The
work concerns delicti responsibility ensuing from the exploitation of traffic
means. This source of damage origin is also the source of increased danger,
though no such term is used in regard to Article 999 of the Civil Code of
Georgia. Any means of transport represent a source of increased danger, since,
ensuing from its constructive peculiarities, the ability of the person driving
it, and from the characteristic feature of movement to proceed under inertia,
it appears impossible to break the speed inherent to this transport and bring
the car to an instant halt that creates the utmost danger for surrounding
people. Responsibility for the damage caused by increased danger is
characterized by one more, most important property. In this case the
responsibility ensues not only on the basis of intentional or careless guilty
attitude of the wrongdoer towards the ensuing result, but also with no guilt
present, which is an exception from the general rule of guilty responsibility.
In the work, by means of applying transport codes, statutes and special
literature, the provisions of Article 999 of the Civil Code are investigated.

"On the Rights of the Child", the Hague Convention of 1993 "On
Protection of Children and Cooperation within the Scope of the International
Adoption", the Civil Code of Georgia, and the Law of Georgia of December
18, 2009 "On Adoption and Foster Care". International adoption is

factors for the analysis may be: family conditions, age (of family members) and
nationality. This publication presents the methodology, which serves to show
social differences regarding life expectancy. The results demonstrate the
dependence of life expectancy on the income level. Particularly, higher the
income, longer life expectancy. Such tendency is more sharply revealed in
males. In developing countries, a politically managed system of family planning
becomes more and more popular. The consequence of such policy is the essential
reduction of the birth rate, which is typical for developed countries. However,

“Tax
targets” are common tools in tax administration in developing countries but not
unknown in others. Tax administration based on tax targets invariably leads to
corruption, under-collected revenue and over-stated tax arrears that may be
considered collectible. Tax targets must be repudiated in favor of budget
forecasting, which can aid in the growth of the private sector and mitigate the
effects of an economic downturn, coupled with modern tax arrears collection
reform.

Ananiashvili, V. Papava/. Economics and Business. - 2011. - #3. – pp. 10-34. –
rus.; abs.: eng
The
article presents a model of macroeconomic equilibrium in which the aggregate
demand and aggregate supply are considered not at the level of prices, as it is
done traditionally, but in terms of functions dependent on the average tax
rate. The concepts of optimal and equilibrium tax rates are introduced. In the
first case, the volume of aggregate supply is maximal and in the latter case,
the aggregate demand and supply coincide. Based on the analysis of the model,
it is shown that when the government tries to maintain the equilibrium average
tax rate at fixed level, the value of optimal tax rate becomes dependent upon
the price level and relevant change in aggregate demand may lead to the
approximation of optimal rate to the equilibrium rate. It is also demonstrated
that every given value of the equilibrium tax rate can be matched with a set of
functions and curves of aggregate supply and tax revenues of the national
budget.

products) and regulation of existing main socio-economic and technical and
technological problems. The article provides arguments to prove the objective
necessity of realization of the idea as well as economic mechanism of its
realization and expected synergistic socio-economic impacts. Establishment of
new forms of economy, based on social solidarity is especially notable, which
automatically leads to employment of the people living in rural areas, increase
of their income, rise of authority of agricultural labor and complex and
accelerated development of a village.

Economics and Business. - 2011. - #3. – pp. 55-60. – geo.; abs.: eng
D. Hume as an original thinker holds a
prominent position among economists. One of the outstanding facts regarding D.
Hume is that he expressed critics of mercantilism. D. Hume was the initiator of
free trade. D. Hume created his own quantitative theory of money. According to
this theory the amount of money existing in the economy defines the value of
the money and the increase of the volume of money is the main cause of
inflation. D. Hume discussed the issue of interest rates and required imposing
low level of interest rates. He regarded that high level of interest rate was
one of the factors that hindered the increase of profit, which remains stable
even in case of reduction of interest rates or the “Investment Effectiveness”.
The ideas of D. Hume were lately used by other economists.

It is a widely
recognized fact that nearly since the second half of the twentieth century the social
development of the world has been going on in conjunction with the
globalization process. Undoubtedly, Globalization is a key term within our
epoch, but a clear and unambiguous definition of this term has not been
established yet. A comparably complete definition of globalization can be
formulated as follows: Globalization is a process of formation of the united
world, which is carried out by spreading of economic, political, social and
cultural values of the developed countries to diverse areas of the developing
and backward countries. The united world itself is presented as a
planetary-scale, unified, but diverse system, where each state, with its
political, economic and cultural individuality, is integral part of this system
without contradiction with the principles of the common system. The principles
of the unified system are: respect for human rights; freedom of
entrepreneurship; fair distribution of products of economic development;
sustainable development; respect of cultural, religious and language varieties.
We can identify the following characteristics of globalization: objectivity,
irreversibility, progressivism and historical-logicality. The main trends of
globalization are: ideological, institutional, political, military and economic
globalization.

The
article considers the issue of possibilities to overcome basic contradictions
of capitalism by using the Keynesian model of state regulation of economy. It
is shown that by means of Keynesian model of state regulation of economy, which
is still used today for managing the economies of developed countries, it’s
impossible to achieve macroeconomic balance not only practically, but also
theoretically. It is also stated in the article, that overcoming of the main
contradictions of capitalism was impossible on the basis of alternatives of
Keynesian theory, such as neoconservative and neo-liberal concepts. Current
global economic crisis proves this.

probability of a negative deviation of the real expected result. There are three
main categories of banking risks: credit risk, market risk and operational
risk. Banking Risk adjustment is a combination of methods aimed at protecting a
bank from risks. Financial globalization has increased the importance of
international regulation. Basel II is the second of the Basel Committee on Bank

The article discusses the dynamics of the
share of income, received from taxes in the formation of budget revenues and
grant execution and Georgian state budget revenues in 2000-2010 years. The
focus is directed to the structure of direct and indirect taxes and optimal correlation
in budget revenues. The article also analyses the changes made in Tax Code
directed at the optimization of the country’s tax policy and tax rates and
those shortcomings, which are still characteristic for Georgian tax system. On
this background, the basic directions for improving the country’s budget and
tax policy are identified: the necessity of reducing the share of indirect
taxes in budget tax incomes; to develop an effective mechanism for distributing
general state taxes between budgets; strengthening the control over purposeful
distribution and use of credits taken by the state; optimization of tax amounts
and separate types of tax rates.

Introduction
of engineering decisions in the practice as well as implementation of any
investment activities are preceded by substantiation of their economic
appropriateness. For this purpose, the methods of defining economic
effectiveness are used in practice. The mentioned envisages, on one hand,
usage of coefficient for long-term investments to bring them to the moment of
time when the investment begins achieving the result. It is defined by
normative means instead of which the definition of this coefficient is offered
against the inflation rate. On the other hand, it is necessary to change the
so-called “normative coefficient of effectiveness” used when defining economic
effect with the coefficient of average rate of bank loan. Such approach to
effectiveness makes the calculations more credible and closer to the reality.

9.A3.29. Practical realization of multiple-factor
economic-mathematic models of evaluation of efficiency of investments in power
engineering of
The current methods of the evaluation of
efficiency of investments are characterized by serious defects. Elaboration of
the evaluation of efficiency of investments in power engineering on the basis
of comprehensive scientific research becomes a subject of great importance.
By taking into account the results of scientific research and global experience
in the investment policy, generalized integral multiple-factor criteria of the
evaluation of efficiency of investments in power engineering being of a
complex character and capable of objective evaluation of the ratio between
used investment resources and efficiency of invested objects’ future
functioning, that will guarantee the interests both of investor and
investments consumer, are elaborated. Time, inflation, the value of fund
payback coefficient, exchange rate of national currency and interest rate
parameters are accepted as the factors in the criteria. According to the
specific character of the structure of power engineering and on the basis of
the selected criteria several modifications of multiple-factor economic-mathematical
models of the evaluation of efficiency of investments are established. These
are: rehabilitation efficiency evaluation criteria of existing power
enterprise, construction efficiency of power enterprise, and foreign
investment efficiency evaluation in constructing local power enterprise. Due to
approbation of the offered methodology in reality, investment efficiency was
assessed in the key power enterprises, such as: Enguri HPP, Tbilsresi SPP,
Gardabani gas turbine power plant and the Georgian national power grid on the
basis of initial information received by analysis of technical, economic and
statistical data, also audit reports. Calculations were made by a special
computer program in Visual Basic, which comprises the efficiency evaluation
multi-criteria algorithms. The research result shows that the investment had
ecological, technical and local social effect. The reliability and functional
efficiency of the enterprise raised but investment efficiency is still low and
payback period may last too long, except the gas turbine power plant which was
constructed by means of foreign investment. Special measures should be
undertaken to reduce management and operational costs.

9.A3.39. Concept of sustainable development from the
outlook of the 21st century. /O. Keshelashvili,
The article underlines that the economic
model of the 21st century is completely different from the models
and attitudes predominating some 20-30 years ago. Nowadays, the priority is
given to sustainable development. It is mentioned that since the 1990s the
ecology problem has acquired global character being reflected in the following:
natural restorable resources (tropical forests, fish resources, etc.) are no
longer self-renewing; the world eco system is being ruined, most species of
flora and fauna are disappearing; more and more areas of the planet have
transformed into zones of ecological risk; prospective climate change has been
regarded as the most urgent challenge. It could be definitely said that
sustainable development should become the basis for modern ecological-economic
growth. There are four criteria of a more detailed analysis of sustainable
development. Concepts of weak and strong sustainability are distinguished for
making a more detailed analysis of sustainable development. Given that the
concept of sustainable development has not been finally defined, the author
proposes own scientific wording of it.

Due
to inexistence of a generally accepted, or standard-defined, crude oil
cost calculation method, the author has attempted to develop own
approach to the issue. Namely, if a commercial extraction of oil is in
process, it would be economically, as well as procedurally, justified
to include in crude oil cost not only production costs, but also the
depreciation of capitalized costs. On the contrary, if the commercial
extraction of crude oil has not commenced and respectively capitalized
costs are not being depreciated, the cost of the accumulated crude oil (as a
result of miscellaneous exploration operations) should be assessed
by taking into account only the direct or overhead costs being associated
with the oil accumulation.

The
article discusses the issues concerning accounting of documentary credit
operations. Taking into consideration the available international practice, the
importance of execution of documentary credit operations is mentioned. The
general impossibility of existence of an interest-free bill of credit is
stressed. In any case, the buyer will cover the value of the bill of credit,
including the actual market interest that equals the current (discounted) value
of the credit bill due, rather than its nominal value. The author argues the
proposed issue based on specific examples using the simple and compound

culture of a person, formation of habits of using information for a person’s
development and self-assertion which are the inseparable and indispensible
components of a person’s common culture. The common-strategic goals and the
desirable consequences should be defined concretely in the tasks of the course.
The list of suggested tasks reflects comparatively independent subject’s sphere
of informatics. Above mentioned task’s system represents the fundamentals for a
new input in informatics and makes it easier to break this course into separate
disciplines, modules, themes or variations. Optimization and refinement of
disciplines of informatics studies should be maximally oriented at the
consequences of teaching at public schools, higher educational institutions and
post graduate studies. The concepts of teaching informatics should be refined,
improved and brought closer to each other. There is an argumentative judgment of
defining the concrete functions of informatics according to the levels of
teaching and subject sphere, the integral and interdisciplinary character of
informatics is also highlighted in the article. As a consequence of realization
of represented concept the system of informatics study should ensure the

During centuries, morale offered to people specific reference points expressed

in the understanding of the “existing” and “required”. The way out should be

phenomenological. Although the phenomenon of life starts to be realized on a
level of cell and does not manifest itself in the atomic (quantum-mechanical)
sphere, the phenomenological openness of a quantum system towards life makes
such interpretation admissible. According to the author, life in a micro-world
plays a role of an unknown, metaphysical object. The relation of quantum
mechanics to the metaphysical mystery of life conditions a definite freedom of
quantum particle on the one hand and the integrity of quantum cognitive
situation on the other hand. The quantum situation is open towards the life
phenomenon; it exceeds, thus, the micro-world borders and embraces the human
creative reality, art, literature, manifests dualism, and, concurrently, unity
of the creative freedom and vital necessity in the whole life.

with a reference to intuition or Sat in Śankara’s Advaita Vedanta. /O. Louchakova-Schwartz/. Culture &
Philosophy. – 2011. - pp. 40-61. - eng.; abs.: geo
The author offers an analysis of direct intuition
in Tymieniecka’s journey of knowledge, with a sense of internal stillness and
gratitude. Perhaps the above set of mental acts can be viewed as an algorithm
of philosophical knowledge. The technical aspects of the method are nonexistent in Tymieniecka’s case, but her general
gnoseological stance is distinct and unique; it is the novum of direct intuition. In the analysis of Tymieniecka’s use of
direct intuition, the author made some use of the noēma-noēsis theory of intentional consciousness. However,
as it is mentioned in the discussion, Tymieniecka herself extensively
criticizes that theory’s claims to universal applicability; Tymieniecka’s broad
contextualizing eliminates any doubt that imagination as a cognitive function
and as Imaginatio Creatrix is much
more prevalent in life than the intentional acts of consciousness. Therefore
the author has to establish a delimiter to her own analysis: positioning direct
intuition within the conceptual network of intentional consciousness limits the
possibilities for understanding the former and semantically narrows the
clearing within which imagination can be fully understood as part of one’s own
logoic manifestation. Juxtaposed with the fact that Tymieniecka’s discovery of
the crucial role of imagination in ontopoietic networks is
direct-intuition-based - what else could it be?- these points lead her to
believe that the very framework for the analysis of direct intuition needs to
be eventually revised. It is possible that the concept of direct intuition, which
is the major vehicle of Tymieniecka’s insight, itself needs further
clarification in order to understand Tymieniecka's method in her discovery of
the role of imagination.

9.A6.6. Science and technology in the context of culture.
/I.
Kalandia/. Culture & Philosophy. – 2011. - pp. 62-67. - eng.; abs.: geo
It is well known that the specific
characteristic of man is that he transforms nature and the surrounding reality
according to the laws of beauty, i.e. according to values and thus creates a
completely new reality – culture. Transformation of nature according to values
supposes man’s freedom and activity as necessary pre-conditions. Free activity
is creative activity. Creativity is a necessary moment of man’s transforming
activity. Free creative activity is essential for man not just because it
differentiates him from any other existing but because it, as a necessary
pre-condition of man’s transforming activity, has explanatory power. When we
say that man transforms his own self in the process of transforming the reality
we mean his creative activity. Man transforms the reality on the basis of
understanding and comprehending regularities of the reality, determining the
essence of things and events. Cognition is a complex process. Truth is not given
“ready-made” to man. In order to grasp the truth man is to activate his
consciousness in many directions. Cognition by necessity implies an active
attitude of the subject to the object of cognition. Man’s creativity in the
process of cognition results in producing new cultural values, new knowledge
and therefore cognition is not only a source of new knowledge but a component
necessary to form and develop man’s essential powers. The author argues that
inevitable condition of establishment of human ideas in society is the
development of spiritual values. Therefore we must restrict the tendency of
making a fetish of scientific thought. Science and technology must be
considered in the context of culture to keep it in the frames of system of
human values.

following experiment: n-type ZnO was implanted with F^+ ions at the
concentration 10^20 cm^–3 at the energy E = 110 keV and at the dose D = 10^16
cm^–2. Healing of the created defects in the implanted ZnO crystals were
carried out by radical-beam-quasi-epitaxy (RBQE) method. According to the
measurements with van der Pauw method the hole mobility, hole concentration and
resistivity were found as 270 cm^2 / V s, 1.0*10^19 cm^–3 and
2.3*10^–3 Ohm cm, respectively. In photo-luminescence (PL) spectrum (recorded
at T = 70 K) of p-type ZnO:F layers maxima at l = 369.1, 374.5,
382.4, 389.9 and 401.0 nm were observed. Here we demonstrate the ability of the
RBQE technology for control of electrical and optical properties of ZnO
material.

Faraday rotation in ultrafine magnetic structures. /L. Kalandadze/.
Nano Studies. - 2011. - # 3. – pp. 157-162. - eng.; abs.: geo., eng.
The
Faraday rotation is considered in magnetic fluids based on particles of
magnetic oxides, for the optical constants of the material of which, n and k,
the relation k^2 << n^2 holds. The Faraday rotation is represented within
the theoretical Maxwell–Garnett model. A theoretical analysis has shown that
Faraday rotation for magnetic fluids is related to the Faraday rotation on the
material of particles by the simple relation. According to this result, in
specific experimental conditions the values of the Faraday rotation prorate to
q, which is the occupancy of the volume of the magnetic fluid with magnetic
particles, and spectral dependences of the Faraday rotation in magnetic fluid
and in the proper bulk magnetic are similar. I hould be underlined that this
result should be correct for all magnetic ultrafine media with the same
relation between optical constants n and k.

The
effect of the magnetic particles concentration q on the magneto-optical
properties of an ultrafine magnetic medium has been evaluated in the case of

Nanostructured electrodes for energy conversion devices. /A. Tavkhelidze/.
Nano Studies. - 2011. - # 3. – pp. 187-198. - eng.; abs.: geo., eng.
Recently,
new quantum features have been studied in the area of nanostructured quantum
wells (NQW). Periodic ridges on the surface of the layer impose additional boundary
conditions on the electron wave function and reduce the quantum state density.
The electrons rejected from forbidden quantum states have to occupy the states
with higher energy. As a result, Fermi energy in NQW increases and work
function (WF) decreases. We investigated a low WF electrode composed from a
metal NQW layer and a base substrate. The substrate material was selected so
that electrons were confined to the NQW. The WF value depends on ridge geometry
and electron confinement. We calculate WF in the metal NQW films grown both on
a semiconductor and metal substrates. In the case of semiconductor substrate,
wide band gap materials are preferable as they allow more reduction in NQW work
function. In the case of metal substrate, low Fermi energy materials are
preferable. For most material pairs, the WF was reduced dramatically. Such
structures, can serve as electrodes for room temperature thermionic and
thermotunnel energy converters and coolers.

Magnetoplastic effect in LiF crystals X-rayed in a weak magnetic field. /M. Galustashvili,
M. Abramishvili, D. Driaev, V. Kvatchadze,
The
magnetoplastic effect studies in LiF crystals have shown that under a combined
action of deformation and weak magnetic field the yield stress decreases twice
and after removal of the field it restores the original value in about
twenty-four hours. Theextremely low-dose X-raying, combined with magnetic
field, also exerts an unhardening effect on LiF crystals. The observed
magnetoplasticity can be attributed to spin evolution in a two-spin nanoreactor
produced by paramagnetic defects in the system dislocation-stopper. Magnetic
field does not induce appreciable changes in electron optical absorption
spectra measured concurrently.

The

has been obtained in a new theoretical approach, without using the
phonons-conception – by the direct analysis of the thermal excitation of atomic
vibrations. It allows a quite good qualitatively description of both low and

fitting the theoretical curve to the experimental points available for

Many problems of technology and science are
reduced to the solving of partial differential equations with different
conditions. To receive the numerical solutions of such problems, a diversity of
difference schemes of the different order of accuracy is used. One of such
approximating methods is known as a method without saturation. One approach to
this method was received by means of the approximating method of the
academician Shalva Mikeladze for the ordinary differential equations, which
gave a possibility to raise the order of accuracy by increasing the number of
approximating points. Using discrete and semi-discrete approximating schemes
for solving the boundary value problem for the elliptic type partial
differential equations with Dirichlet condition produced a type of matrices
known as centrosymmetric or double symmetric ones. Peculiarities of such
matrices give a possibility to reduce them to the half-order matrices and
facilitate the construction of a characteristic equation. The characteristic
equation of such matrices is constructed in factorized form. All eigenvectors
are given in explicit form. Such type of matrices has the same eigenvectors
(eigenspaces) which in general do not depend on their elements. The diagonal
form of such matrices contains their eigenvalues. When centrosymmetric matrices
are also symmetric, matrix of spectral decomposition is constructed including
the fourth order. Columns of the matrix of spectral decomposition represent
orthonormal eigenvectors of the initial one. Matrix of decomposition and its inverse
reduce the initial matrix to the diagonal form, which is very useful to find
any power of the given matrix, raising into the power only the real eigenvalues
of the diagonal form. Few theorems are represented to emphasize the
peculiarities of such matrices.

in the classical theory during pure bending of plates really differ from the
stresses caused by outside moments, owing to which both the bending moments and
bents differ from the real one. If the values on the right part of the
equations of Hooke's generalized law are taken as stresses, then these stresses
and the bending moments produced thereby will no longer comply with the
boundary conditions on the plate edges, where the bending moments should equal
the moments acting as outside loads. All these contradictions result from the
fact that the Poisson's ratio is accepted as a constant value. The

An actinomycete (bacteria) strain Streptomyces glaucus 71MD isolated
from the soybean rhizosphere in Georgian soils is examined for its ability to
produce gold nanoparticles from an aqueous solution containing HAuCl_4
(chloroauric acid). The obtained results clearly show that gold nanoparticles
formed by reduction of Au(III) ions by Streptomyces
glaucus 71MD are crystalline in nature and are generally produced

# 4. – pp. 133-138. - eng.; abs.: geo., eng.
The
purpose of this work was to study the growth of germanium nitride nanowires at
relatively low (500 – 580 ^oC) temperatures. A decrease in the synthesis
temperature was caused by the application of active (N_2H_4) vapor. The
hydrazine was containing 3 mol. % of water molecules. It was established that
at 480 ^oC, due to the high reactivity of water the ball-shaped GeO_x clusters
were formed on the Ge source surface. Beginning from 500 ^oC the nitriding
ability of hydrazine decomposition products prevailed over the water induced
effects and Ge_3N_4 nanowires started to grow on the surface of GeO_x clusters.
They grow from the Ge-enriched nanodroplets through the vapor–liquid–solid
mechanism. At temperatures exceeding 530 ^oC the growth mechanism changed to
the vapor–solid method and Ge_3N_4 nanobelts were formed. All grown 1D
nanostructures exhibited the a-Ge_3N_4 structure.
It was found that the nucleation proceeds with the formation of both a‑
and b-Ge_3N_4 nuclei. However, only a-Ge_3N_4
grows in the form of one-dimensional nanostructure.

rises in rat brain cells, which is accompanied by an increase in the intensity
of lipid peroxidation shown by a rise in the quantity of one of the primary and
final products of this process – diene conjugates and thiobarbituric acid
active compounds, including malonedialdehydes. At the same time, activity of
anti-oxidant enzymes, such as superoxidedismutase and catalase, is intensified

Khachidze, M. Kiladze,
Thermostability and energetics of melting
process of chromatin in the composition of normal and ductal breast carcinoma
tissues at various stages of disease have been studied. It has been shown that
the melting process of normal tissues proceeds in five transition stages at 55,
66, 78, 97 and 103°C. The first, second, and third transition stages are
connected with melting of proteins, and the fourth and fifth transitions correspond
to chromatin denaturation. The paper considers only the melting of chromatin.
It was found that stability of both domains of carcinoma chromatin decreased by
5.0 and 3.5°C compared to the norm, and, which was more important, nearly 20%
of ΔHd from transition V was lost and added to transition IV
without change of total chromatin denaturation enthalpy. The authors explain
this change by strong rearrangement of the structural organization of both
domains of chromatin – hetero and active chromatin. In particular, unfolding
about 20% of 30nm fiber structure and its pass to 10 nm fiber and partial
unfolding of 10nm fiber due to the loss of H1 histone and core histones H2A/H2B

An experiment was arranged to compare enzyme
maceration to cold maceration, to study their influence on quantity of total
phenols in red wine, and to determine the optimal length of cold maceration.
The Folin- Ciocalteu spectrophotometric method was applied to determine total
phenols. Cold maceration was conducted during 6, 12, 24, 36 and 48 hours at 4°C
temperature. Enzyme maceration was carried by enzyme preparation Extrazyme
(Institute Oenologique De Champagne) according to manufacturer′s
recommendations. The data obtained by the spectrophotometrical analyses confirm
that the cold maceration conducted at 4°C temperature promoted to an increase
of the content of total phenols in red wine. The pre-fermentation enzyme
maceration is more effective way to increase phenolic compounds in red wine
than cold maceration under the above-mentioned conditions. The cold maceration
at 4°C temperature elevates the level of total phenols during 24 hours.
Therefore, 24 hours are found to be the optimum time. The use of the enzyme
preparation “Extrazyme” is expedient for making wine rich in phenolic compounds

In the work, an analysis of terminological
discrepancies during manufacture, sale and use of radioprotective agents is
made It is shown that non-use of the standard radiobiological characteristics
(the dose conversion factor - DCF) might lead to problems associated with
estimation of the radioprotectors’ activity level of the made preparations, as
well as to serious problems in connection with their use. Such a view is
particularly important in respect of defining the principle of the time of
administration of agents to the organism (i.e. prior or after the radiative
effect). If in the first case the priority processes are the inhibition of
various physiological and biochemical processes and decrease in cytological
toxicity of free radicals upon use of the agents, the reactions associated with
activation of the post-radiation restoration processes can take leading
positions upon the use of such an agent after the radiative effect. Therefore,
the terminological discipline should be strictly observed. Thus,
radioprotectors may be defined as agents administered prior to radiative effect,
while radiopreventive ones – as the agents administered after irradiation.

The quantitative data of geological

conclusions made on their basis are more or less prognostic. The main parameter
of ore deposits economic evaluation – quantity of useful components - is also
prognostic. Determination of the quantity of the metallic component in ore body
is achieved by processing data obtained from discretely located observation
points. In cases with extremely irregular mineralization, using the method of
arithmetic mean gives an unacceptable error that significantly decreases the
reliability of estimation and increases the costs of mining. We have performed
calculation on data for more that 2000 samples from 26 locations that clearly
show the strong correlative link between the quantitative values of the
variation of mineralization distribution (variation factor) and the relative
error. This interrelation gives an opportunity to correct the amount of content
of the component calculated by the method of arithmetic mean with the
regression equation using the variation factor.

Hypothetical versions of granite forming
within the continental crust are considered with their weak and strong sides.
It is the first attempt to design a completely new model of granite forming and
development under conditions of the middle crust. The issue of the source of
petrogenic elements of the said rocks is considered on the basis of the
available factual data. The granite forming is found to take place under conditions
of the continental crust for the last 3-3.5 milliard years of the Earth
development. The granite forming was going on at the expense of granite itself
according to the principle of self-generation of the petrogenic elements. This
is evidenced by the hydrolysis process (kaolization) going under exogenic
conditions, as a result of which a complete release of potassium, aluminum and
of their compounds occurs. Based on the geochemical peculiarities, the granite
petrogenic elements remain on the spot, facilitating thus the preparation of a
source for these elements. It has been found that the upper mantle did not
practically take any part in the granite forming process within the middle
crust. According to the geochemical data, most of the late-Variscan granitoids
are attributed to the upper crustal formations and mostly correspond to S-type
granitoids.

In
the past centuries pyrometallurgy was the only route to extract metals from
ores and this required a large capital investment many countries could not
afford to raise. This situation encouraged marketing of concentrates. Today,
metallurgists have the option to use the hydrometallurgical route to process ores
and concentrates at a reasonable capital investment. This opened the way to the
possibility of processing ores locally. When need arises to increase production
new units can be added economically. This is not possible with
pyrometallurgical processes because one large furnace is more economical than a
number of small furnaces with the same capacity due to heat radiation losses.
In summary, mineral processing has made great progress in the past thirty years

Pyrometallurgical
processes involve a preliminary step to render the ore or concentrate more
amenable to further processing. This is then followed by a reduction or a
conversion step to liberate the metal and finally a refining step to get the
pure metal for the market. When the flotation process was introduced it
permitted the utilization of low great ores which resulted in fine particles
that cannot be introduced into shaft furnaces in use. As a result new unit
operations were invented to cope with the situation. Although fine particles
may be desirable because of the large surface area and the rapid rate of reaction
they have the disadvantage of generating undesirable dust. Fine particles are

solutions, the production of aluminum takes place from molten salt. Electrowinning
of zinc and aluminum are energy intensive operations while electrorefining of
copper is not. Electrometallurgy cannot be isolated from other areas of
extractive metallurgy because of its dependence on the feed material as well

irradiated with 25 MeV protons at 300 K. The irradiation dose varies within the
range (1.8 – 8.1)*10^12 cm^–2. The measurements are carried out by means of the
Hall technique in the range of temperatures T = 77 – 300 K. In samples
irradiated with different proton doses, a sharp increase in the experimental
effective Hall mobility μ_eff or a deep minimum in the dependence
μ_eff = f(T) in the region of phonon scattering of electrons is observed
immediately after irradiation or after aging of the samples, respectively. The
observed effect is attributed to the formation of high-conductivity –
metal-like) – inclusions in the irradiated samples and to changes in the degree
of screening of the inclusions by impurity–defect shells in relation to the
irradiation dose, the time of natural aging, and the temperature of
measurements. The impurity–defect shells are formed around metal-like
inclusions during isochronal annealing or natural aging of the irradiated
samples. It is suggested that metal-like inclusions formed in the n-Si crystals
on irradiation with protons with the energy 25 MeV are atomic nanoclusters with
an 80 nm radius.

It is established
that upon use of 3.7-4% CMC (carboxymethyl cellulose) to thicken the emulsion,
the latter retains stability. At the same time, the emulsion becomes firm and
its main principles are violated – since the oxidizing agent and fuel are no
longer fluid. It should be mentioned that the KMC binds the emulsion in one
direction. Upon use of a high-polymeric flocculant “Magnafloc 10”, the emulsion
is bound from all the directions, becomes viscous, fluid and is capable of
preserving the both phases in a liquid state. Under laboratory conditions, the
testing of the emulsions made by us showed that no emulsion retains stability
while passing a water column – the penetrating water divides the emulsion. The
emulsion retains stability when the silicate sodium structure builder and the

Mathematical formulas determining the major
design parameters – cylinder diameter and height – of spray dryers were
theoretically derived. The dryer’s dimensions were found to depend on the
physical-mechanical properties of the dryable material, parameters of the
working drying agent and the basic specifications of the drying process. At
that, the physical-mechanical properties of the part determining the spray
dryer’s dimensions are the coefficient of aerodynamic resistance, the part’s
mass and effective cross-sectional area. Out of the working agent’s parameters,
the drying process is influenced by the airflow density, the initial and final
humidity, the absolute temperature and pressure, as well as the product’s
initial and final humidity and the dryer’s performance - out of the drying

still active. Therefore, together with the processes ongoing in physical
solutions, the tissue structure destruction and retardation of biological
processes are additionally taking place therein. For the purpose of studying

Bulletin of
With progressing earth history temperatures
and precipitation have globally, regionally and locally changed. In addition to
extraterrestrial reasons also terrestrial reasons like volcanism, forest fires,
changes of global ice, snow and vegetation cover have caused such changes. For
the last 100 years the global mean temperature has increased to actually more
than 15°C, which is widely assumed to have not only natural but anthropogenic
reasons: A reduced water evaporation from agricultural land in contrast to
natural forest, emissions of warmth and carbon dioxide especially in
urban-industrial agglomerations, and the release of methane and nitrous oxide
in agriculture are the most important impacts. It is assumed that in the 21st
century the global mean temperature will rise by another 2-3 C, mainly caused
by a higher use of fossil fuels and an intensified conventional agriculture.
Increased temperatures, higher CO2-concentrations near the soil
surface and higher precipitation rates lead in principle to a higher formation
of biomass. More crop residues and higher temperatures also stimulate the
activity of soil organisms. Higher soil temperatures also stimulate chemical
weathering. On the other side higher rainfall can wash out more solved
nutrients. But the expected climate changes and their effects on soils can vary
to a large extent. The predicted rising sea level will increase the flooding of
coastal soils, so that dikes have to be built or heightened. Higher temperatures
in coastal soils will intensify the microbial formation of green house gases.
Permafrost soils will melt so that their agricultural use may be partly
possible.

Nowadays, a growing interest in the use of
biomass for the purpose of energy generation conditioned by the necessity of
environment protection and depletion of fossil fuel is observable. One of the
effective solutions of these problems is the establishment of energy
plantations with fast growing woody species, which already play an important
role in the energy supply of different countries. In our opinion, similar
plantations can be effectively used in the future to meet demand for fuel wood
in our country, and consequently favorable conditions for the development of
energy forest in Georgia are to be created.

Determining which of
the road-conditions parameters are directly associated to road accidents
recurrence is of importance in the field of road-accident prevention. Given an
accident scenario, it is a common practice to evaluate road-accidents related
parameters via deterministic dependencies such as the driver's accuracy of the
subjective assessment, his ability to implement a given task and car dynamics.
Still, it is better to take into account also the statistical nature of such
processes. The main advantage of a probable evaluation is the synthesis between
deterministic and stochastic characterizations. These may provide an answer for
the vehicle motion, enabling, in turn, a scheme for accident prevention. In
this paper, we made an attempt to define probable characterizations of road
accidents, in which an obstacle appeared in use of ECS. To these end previous
incident parameters were also taken into account (parameters associated to the
vehicle, the obstacle, the road and the dynamic characteristics of the vehicle
etc.). Our main result is calculation of a car-obstacle collision probability
based on Monte-Carlo method. Furthermore, we were able to extract some
analytical dependencies, relating to the avoidance probability of incidents
with several influence arguments. Finally, these provided us with a platform
for solving some practical problems in the field of road safety.

periodicity of scheduled (preventive) maintenance. This model describes in
detail the possibilities and conditions of performing the CE preventive
maintenance. Practical application of the proposed method is demonstrated in an
example of the CE preventive maintenance periodicity optimization. The
presented method indicates, that data from observation of vehicle operational
reliability can be employed successfully for optimization of their maintenance
conditions. By means of the proposed model, it is easy to illustrate the
possibilities of significant savings in maintenance by setting an optimal

for their exposure are likely to influence the uptake, sub-cellular distribution,
and toxicity of gold nanoparticles. However, investigations of metal
particulates are still in their infancy at this stage and are concentrated on
revealing the toxicity, safety, tissue distribution, antibacterial properties
and cellular uptake of gold nanoparticles. Consequently, more comprehensive
studies are required to more fully understand the toxicity versus safety
associated with metal particulate exposure. Inevitably, any emerging technology
requires extensive safety assessment before coming to market, including
diagnostics, medications and cosmetics. While comparing and evaluating newly
established properties at nano-scale, consumers may experience confusion
concerning the safety issues. Lately, responsibilities for the control and
regulatory mechanisms have also applied to the safe utilization of
nano-particles in cosmetics.

Wavelet technologies in nanomedicine. /I. Chkheidze, L. Tokadze/. Nano
Studies. - 2011. - #3. – pp. 163-168. - geo.; abs.: geo., eng.
Wavelet technology is
considered as an example of the application of information technologies in the
HealthGrid and nanomedicine. Digital image processing and signal-computing
tomography studies provide the unique properties of wavelet transforms: data
compression, allocation of the image contours and objects of interest, as well
as cleanup of signals from random errors. It is shown that the implementation
of the algorithm of discrete wavelet in MathCAD program is characterized by
simplicity, speed and accuracy, and the results of such experimental
investigation will help doctors in establishing the correct diagnosis of brain
disease and be useful in automation of the diagnosis process.

We distended the
relaxed porcine left ventricular myocardium by inflating the coronary arteries
with compressed air, using rising pressures between 1 and 3 atmospheres.
Computed tomographic analysis revealed a feathered arrangement of the
myocardium aggregated together within the walls, with an overall system of
spatially netted lamellar structures. Histological examination in orthogonal
planes revealed the lamellas themselves to be made up of endless chains of
myocytes, which show the well recognized systematic change in helical angle
when traced through the thickness of the walls. The pneumatic distension had
opened clefts between the lamellas, with sparse and loosely aligned fibrous
tissue present within the clefts. The lamellar structure itself is continuous
through the walls via a system of interlamellar connections from epicardium to
endocardium, and from the ventricular base to the apex. The ventricular walls,
therefore, which appear compact when sectioned without pneumatic distension,
are shown by distension to be composed of a system of three-dimensionally
curved and nested blades, with the individual blades taking their origin from a
central circular myocardial collar, Krehl´s Triebwerkzeug, and then
extending with opposing curvatures towards the endocardium and epicardium.

Metabolic syndrome
(MS) is a major public health threat. Individuals with MS are at increased risk
for development of chronic kidney disease (CKD). Despite effective medical
interventions that have targeted vascular renin-angiotensin system (RAS)
blockade the prevalence of CKD remains considerably high. Few studies have
directly compared the reno- protective effects of Angiotensin II-receptor
blockers and Angiotensin-converting-enzyme inhibitors (ACE) in patients with
MS. The aim of the present study was to compare the renoprotective effects of
Angiotensin II-receptor blockers and Angiotensin-converting-enzyme inhibitors
(ACE) in patients with MS and early nephropathy. In this prospective three year
study, we randomly assigned 123 patients (mean age 45.8±11.7 years, range 31-57
years, 72 male and 51 female) with metabolic syndrome and early nephropathy to
receive either the ACE inhibitor Quinapril (Accupro, Pfizer International, 20mg
daily, 43 subjects) or Angiotensin II- receptor blocker Valsartan (Diovan,
Novartis, 160 mg daily, in 41 subjects) or in combination Valsartan /Quinapril
(160 mg/20 mg daily, in 39 subjects). The endpoint was the change in the
glomerular filtration rate (GFR) (determined by measuring the plasma Clearance
of Creatinine) between the baseline value and the last available value during
the three-year treatment. After three years, indices of GFR increased by 4.2
ml/min/1.73m² in Quinapril-treated patients, compared with - 4.7
ml/min/1.73m² in Valsartan-treated subjects, and - 7.1 ml /min/1.73m²
in Valsartan /Quinapril group (p<0.01). The results indicated that Valsartan
was not superior to Quinapril,but the renoprotective effects of the combined
therapy with Valsartan/Quinapril significantly improved after three years.

During the past
century, the evidence for the risks imposed on human health by excess salt
consumption was compelling. The causal relation between habitual dietary salt
intake and blood pressure has been established through experimental,
epidemiological, migration, and intervention studies. The aim of the work was
to select from persons having normal arterial pressure the salt sensitive ones
and using DASH and sodium-restricted diets to set the perspective for the
development of preventive measures. Salt sensitivity was assessed in
normotensive 54 young and 68 elderly males. Accordingly salt sensitive subjects
were divided into two groups in accordance with age. Salt sensitivity was
assessed by the difference of mean arterial pressure (MAP) on high (200
mmol/day) vs. low (40 mmol/day) salt diet. Compliance with the diet was
confirmed by measurement of 24-hour urinary sodium excretion during the last 2
days of both weeks. As was mentioned, both the DASH diet and DASH diet with
lower sodium intake caused mean arterial pressure decrease, but the combination
of the DASH diet plus lower sodium intake consistently produced the greatest
mean reductions in blood pressure with peak levels in the elderly. Based on our
results, we can suggest that in spite of the fact that diet modifications
cannot influence the genetic nature of salt sensitivity, it can lower the mean
arterial pressure in normotensive salt sensitive individuals, thus creating the
possibility of its use for hypertension prevention.

One of the factors of
pain is the damage of nerve fiber structure. Due to the fiber damage passive
penetrability of Na+ ion is increased, leading to the change of
membrane polarization and additional local currents with pain syndrome
strengthening. Thus two moments in the occurrence of pain syndrome play an
important role: disfibering of myelin and growth of Na+ -ion
penetrability.

Since 2004, the
nationwide Georgian Longevity Study has been undertaken by Department of
gerontology and geriatrics at the National Center of Therapy. Interesting
features have emerged regarding gender, geography and diet. The female-to-male
longevity ratio is more than six to one and it is not uniform throughout
Georgia, varying according to the proximity of inhabitants to the seashore or
mountains. Significant dietary groups were noted. Although fewer in number, men
are better off functionally and medically. Long-lived people in the mountainous
regions have better state of health than those living near the sea. Similar
findings have also been noted in Korea and Italy. It can be concluded that
habitation might influence gender differences in longevity, particularly via
the influence of diet and physical activity.

We aimed at
evaluating the informativeness of arterial and venous blood indices at
hemorrhagic shock and gravity of hemorrhagic shock in animal models with the
use of the in vitro system AVL (England). The model of severe hemorrhagic shock
(HS) in 2-4 kg anesthetized (nembutal narcosis - 40 mg/kg) male cats (n=8) was
induced by the Wiggers-fine’ method through bloodletting. Intraarterial blood
effusion summary 40mg/kg, till arterial blood pressure dropped to 40mm/hg for 1
hr. Arterial and venous blood gas monitoring was conducted in dynamics: at 30th
min (HS 30), at 60th min (HS 60) and at 80th min. Blood
was taken from femoral vein and artery (v.et.a.femoralis) using microcapillary
TYPPE 551T 1/18 5/100 and studied on AVL (England). A total of 174 blood gas
samples: arterial and venous pH, partial pressure of PC02, mmHg,
partial pressure of PO2 , mmHg,bases excess BE mmol/l, buffer bases
BB mmol/l, bicarbonate HCO3, mmol/l, saturated O2 sat
mmHg, alveolo-arterial oxygen deficiency (AaDO2) and cardio
circulatory oxygen deficiency CCDO2 - % were measured. The obtained
results were analyzed statistically with the use of STX program. Reduction of
arterial blood effusion to 40ml/kg/ led to the following alterations: decreases
in mean arterial blood pressure (from 124 mmHg to 60 mmHg –at HS30 and 40 mmHg
- at HS60), In venous blood control CCDO2 increases from 17.10±1.20
% to 21.43±1.15% . At HS60 and 80th min CCDO2 increases
from 43.3±3.60% to 47.80±1.03% (p< 0.05, p< 0.01, p<0.01). Inarterial
blood control CCDO2 was 0%, while at HS30, HS60 and at 80th
min CCDO2 increases and is equal to 9.0±1.3%, 43.3±3.63% and
50.1±1.3%, respectively. (p<0.01, p<0.01, p<0.01). Arterial PC02 varies
and at HS30,HS60 and 80th min it is 40.55±1.09 mmHg, 32.40±2.40 mmHg
(p< 0.05), 38.66±1.20 mmHg and 45.60±1.3 mmHg(p< 0.05). After 80th
min irreversible changes develop. In the experiments carried out PCO2 differs
from controldata. Arterial and venous blood gas monitoring revealed close
correlation of altered PCO2 and CCDO2 indices with
acidosis, which could be used for assessment of acidosis at hemorrhagic shock.
Changes in venous PCO2 and CCDO2 have recently been shown
to correlate with changes in global tissue perfection (cardio-vascular
system).Such data, available immediately via continuous venous blood gas
monitoring, may be useful for monitoring shockand the response to
resuscitation. The results of blood gas monitoring agrees closely with the
results obtained withthe use of fiberoptic three-dimensional sensors. This
method could be used in different unstable situations. In vitro AVL system
provides additional possibilities to investigate other vitally important
parameters (buffers, CCDO2, AaDO2) etc.

The development of
prerenal azotemia in different pathologies accounts for 40-80% of cases. In
order to identify it, especially at early stages, special clinical diagnostic
methods should be selected. The goal of the present paper is to select a
combination of clinical diagnostic tests to identify the early manifestation of
this pathological mechanism. Three types of prerenal azotemia are known: (1) a
decrease in intravascular volume; (2) a change in vascular resistance; (3) a
low cardiac output. We have studied the second type – 5 patients with liver
cirrhosis in the decompensation stage and the third type - 22 patients with
clinical heart failure (refractor stage, D degree according to Hunt’s
classification). We have applied the following methods of clinical tests: (a)
relation of blood urine nitrogen and creatinine (norm <20:1); (b) glomerular
flow rate (GFR); c) sodium rate in urine (UNa); (d) measurement of
fractional excretion percent of sodium (FENa); e). Osmolality
of urine and blood serum by our construction
(conductometer-osmometer); e) oliguria is defined as urinary output <400-500
ml/d or 20 ml/h. We have determined all the parameters of osmoregulation by
means of the parameters obtained from the device. The same device is supposed
to state the viscosity of urine and blood serum together with osmolality. Due
to our data, in patients with liver cirrhosis the prerenal azotemia occurs at
the decompensation stage, also observed is hypervolemic hypotonic hyponatremia.
Osmalality of blood serum decreases from 275 mEq/kg. Against the backgrounds of
sharply decreased diuresis, urine sodium decreases from 20 mEq/l to 10 mEq/l.
In severe clinical cases the concentration of sodium decreases up to 5mEq/l.
The ratio of blood urine nitrogen and creatinine is 60:1 (the upper limit
20:1). In patients with chronic heart failure (at the refractor stage) under 36
hours of deprivation the urine osmolality was less than 400 mosm/kg. At the
refractor stage, glomerular filtration (GF) makes 1.4±0.42 ml/min. It is
dramatically decreased. Also decreased is the excretion fraction of osmotic
substances (0.83±0.06 osm%) as well as the excretion of free water (TH2O
0,24±0,3ml/min). The results obtained show the already formed prerenal
azotemia. The designed by us micro conductometer–osmometer is in full
compliance with modern standards. In order to expose prerenal azotemia at an
early stage, much wider combinations of clinical laboratory tests are needed.

The aim of the work
was to identify a level of increase in general cholesterol, low-density
lipoproteins and triglycerides in different age groups – from 25 - to 50, from
50 – to 65, from 65 – to 75 and up to 75 years. Based on the 2009 observation
data, the contingent studied for lipid metabolism amounted to 340 (297 men, 43
women) patients. The carried research vividly showed that an increase in
general cholesterol in all age groups was almost equally proportional (18 to
27%). The same holds true in respect of triglycerides, their high level was
within 35 to 38%. As for the low-density lipoprotein increase in any age
groups, its maximum made 93 to 100%. Thus, the timely detection of dislipidemy
by age groups means primarily prevention of atherosclerosis and related
cardio-cerebral-vascular complications. It would be reasonable to carry out a
wide-range research of lipid metabolism in children and adults to ensure timely
control of atherosclerosis development.

Rehabilitation. – 2011. – pp. 51-62. – geo.; abs.: geo., eng., rus.
The purpose of the work is to develop a method for establishing
the effectiveness of therapeutic riding and having it tested in the
rehabilitation of patients with stage I-II coxarthrosis. Under
observation were 60 women, aged 24-56 and, of them 30 healthy and 30 patients
with stage I-II coxarthrosis. To establish the effectiveness of
therapeutic riding, we observed the hip joint function using a biomechanical
curve of the hip joint at different gaits of a horse, i.e. we have
developed a method of functional diagnostics with application of horse riding
as an exercise. For this, an optical method is used, in
particular, accelerated filming by professional camera (Mini DV Sony GCR-VX2100
PAL). The resultant video recording was divided into exposures, measuring on
each the angle of the joint hip flexion. By the
angle values, a biomechanical curve was built. We studied
the wave curves (their number and shape), their length and width, amplitude,
angle of movement and their range. To establish self-descriptiveness
of the biomechanical curve, the curves of healthy subjects and patients during
the horse’s going at a slow pace and at trop were studied and compared. The
biomechanical curves were also analyzed in dynamics – prior to therapeutic
riding and 3 months later. Based on these results, it can be said that the
biomechanical parameters of the curves of hip joint at different gaits of horse
(walk, trot) in healthy patients and the stage I-II coxarthrosis were
significantly different (p< 0,001), which allows to recommend the
biomechanical study of the hip joint, in particular the biomechanical
curve, as an objective criterion for evaluating the effect of rehabilitation in
coxarthrosis. In the therapeutic riding dynamics, the
biomechanical parameters of curves during the horse’s going at a slow pace
verged towards the parameters of healthy individuals, while during trot the
shape of the curve radically changed, being shaped to that characteristic of
trot. This in
turn points to the positive impact of therapeutic riding at coxarthrosis stage
I-II.

We studied 226 patients (from 3 to 17 years) with different degrees of
scoliosis, including 58 patients with 1st degree, 55 – with 2nd
degree, 53 – with 3rd degree and 60 athletes (from 6 to 17 years)
with 1st and 2nd degree of scoliosis. During our
investigation we focused our attention on collection of correct anamnestic
data. Clinical investigations included study of children’s physical
development, somatoscopy, orthopedical and radiological investigations. As a
result of 20-day treatment by the above-mentioned methods, improvement of
stance was achieved in 98% in case of 1st degree scoliosis and in
58% in case of 2nd degree scoliosis. Although, in case of 2nd degree
scoliosis, additional 2 courses of treatment (20 days each) were required for
better results. In case of 3rd degree scoliosis, strong muscular

Spontaneous abortions
and inborn structural anomalies are the main complications of diabetic
pregnancy. We made a research to reveal the role of IL -10 in
streptozotocin-induced diabetic outcome of pregnancy in IL-10-/- and
IL-10+/+ mice. According to our results, we can conclude that IL-10
has a major role in diabetic pregnancy outcome. Interleukin 10 knockout
pregnant mice are much more sensitive to sterptozotocin-induced diabetes. We
found out that they have reduced pregnancy rate. During diabetes production of
IL-10 decreases, therefore raises expression of TNFa
in uterine mucosal cells, which leads to increase of NO production. Thereafter,
excessive apoptosis and reduced proliferation processes cause the uterus weight
loss. Consequently, the uterus is not ready for successful implantation; there
are deregulation and dysfunction of important molecules, such as LIF and MMP-9,
responsible for uterine sensitivity acquirement and implantation.

There are two
strategies in modern public health system to preserve health: treatment and
health protection of healthy human. The latter is less prioritized by
government, because nowadays it is more common to eradicate diseases than
preserve the health of healthy people. This has definitely affected the
professional training of doctors in universities, in the curricula of which the
subject of sanology is completely disregarded, while the physiological
reactions of both the pathogenic and sanogenous direction are involved in the
organism in the course of diseases. Based on the above, the psycho-physic
condition and social standing of a healthy person must become the main object
of medical research. Doctors must, in addition to the “case history”, also
start keeping a “health history” in order to identify the health defense and
compensatory mechanism with the aim to protect health and restore the disturbed
homeostasis. According to this position, sanology is the basic science teaching
of health management, the efficient functioning of which is based on the
theoretical and practical achievements in pathology, rehabilitation and general
valeology (health studies).

5 normospermic men
with idiopathic infertility were revealed out of 85 patients fully examined for
infertility. The rest of 80 patients had urogenital diseases of different
etiology with chronic infectious inflammatory pathologies and pathospermia. The
present study has shown that infectious inflammatory processes as well as
resultant complications in urogenital organs impair the ejaculate quality in
regard to fertility. In particular, the ejaculate from all the patients
diagnosed had a markedly decreased number of spermatozoa. Changes in the sperm
volumes were seen in 32(40%) of men with different inflammations of the
genitalia. pH was altered in 62(77%) cases, with a decreased pH noted in 39(62%),
while increased pH was in 11(37.1%) patients. It has been established that
infectious inflammatory processes seriously affect the concentration of
actively motile, especially of fertility –potent (forward progressive) sperm.
The number of sperm leukocytes drastically rises resulting in leukocytospermia
which has been documented in 29 (36.25%) cases. The study has revealed
significant disturbances of spermatokinesis, increase in teratogenic shapes of
spermatozoa, and changes in the biochemical indices of the ejaculate.

chronic heart failure with and without diabetes mellitus demonstrated the
positive dynamics of similar clinical and homodynamic indices in both groups.
In addition to the patients’ clinical status improvement, also improved the
contractile cardiac function. In contrast to other beta-blockers, the
carvedilol treatment significantly increased the cardiac index, stroke volume,
while decreasing the systemic peripheral vascular resistance. All the above is
associated with the multifunctional neurohormonal effect of carvedilol.

Liver damage
represents the most widely distributed pathology. It plays a main role in
morbidity and mortality of human population. According to the WHO, more than 2
billion people suffer from liver damage; this number is 100 times higher than
HIV-infected population. Every year 500 thousand to 1 million new cases of liver
disease are being registered in the CIS (Commonwealth of Independent States).
The article discusses the role of undesirable ecological factors in the
development of liver damage. Admittedly, chemical agents that contaminate
environment may have a direct destructive effect on the liver function, may
change the human organism’s sensitivity to drugs, thus leading to iatrogenic
hepatotoxicity. Some groups of medicinal agents are known to cause the liver
damage and liver dysfunction with different types of clinic-morphological

This region is known for its frequent earthquakes (1991, 2002, and 2009),
landslides and floods (2005). The purpose of the presented study is to identify
in the Racha-Lechkhumi and Kvemo Svaneti Region a connection between natural
disasters (1991-2009) and the population health index, as well as the
preparedness of local case for emergencies. The study is of a retrospective
character, encompassing data of the 1991-2009 natural disasters in the research
region. The used information sources were obtained from the Center for Disease
Control CDC; the Emergency Coordination and Regime Department of Ministry of
Labor, Health and Social Affairs; the Seismic Monitoring Centre. The study
failed to link the population’s health status or a specific disease with the
natural disasters that took place in the region in 1991-2009. However, based on

people with food poisoning decreased from 4597 to 3805 cases, increasing again
to 4667 in 2010. The recent increase in the number of food poisoning may be
explained by two reasons: 1) inadequate control over products, and 2) better
recording of food poisoning cases. It connection with the above, the problem of
comprehensive control over food products (locally produced and imported) with
the aim of preventing the getting of uncertified products to the consumer

to get acquainted with the Good Pharmacy Practice standards presented by
International Pharmaceutical Federation and to conduct inquiry among the
pharmacists working in a pharmacy network; to propose recommendations for
developing GPP national standards taking into account FIP standards. The
results received at the result of inquiry showed that only 30% of GPP national
standards proposed by FIP are fulfilled in our country. Therefore, we consider
it necessary to offer the following recommendations for developing GPP national
standards: - It is necessary to hold conferences, briefings, meetings between
the employees of health care sphere, which will facilitate the collegial
collaboration among them; - It is necessary that the reference books available
to the health products issued with or without prescription in pharmacies; - It
is necessary that the confidential room exist in the pharmacy for sincerer
conversation between pharmacists and patient; - It is necessary to conduct
professional trainings for pharmacists aiming at raising their qualification; -
In case of discovering an error made in prescription, pharmacists and doctor
should confidentially solve the problem; - Pharmacist should not replace/change
the preparation prescribed in the prescription or offer its analogous
preparation without doctor’s consent; - For company, pharmacy and pharmacist it
should be paramount to care for patient and not to focus on profit.

The antiphospholipid
syndrome (APS) is an autoimmune thrombophilic condition that is marked by the
presence in blood of antibodies that recognize phospholipid-binding proteins.
The clinical manifestations of APS include vascular thrombosis and pregnancy
complications, especially recurrent spontaneous miscarriages. Several study
groups have demonstrated the importance of inflammatory mediators in the
pathogenesis of APS. It was also established that tissue factor, p38MAPK,
nuclear factors kappa B, complement system, toll-like receptors and annexin are
integral to the pathophysiology of the disease. These study groups proposed new
targeted therapeutic strategies which include Rituximab, complement inhibition,
anti-cytokine therapy, p38 MAPK inhibitors, nuclear factor inhibitors and
tissue factor inhibitors. Newer therapeutic strategies are being proposed that
might lead to safer and more efficacious treatment modalities in the future.

Acute toxic damage of
the liver is a clinical syndrome developed during exacerbation of pathological
process, which frequently results in an acute massive hepatic parenchymal
necrosis. The morphological base of an acute hepatic failure is the so-call
‘cytological syndrome’ resulting in the damage of cell membranes and then of
cell structures with the development of functional insufficiency. The liver has
a unique ability of reparative regeneration, which is manifested by a
quantitative increase of the peroxisomes, oval mitochondria and endoplasmic
reticulum microtubules. The application of the said ability of the liver is of
much importance in developing the already tested or completely new (cell
transplantation) treatment techniques.

Functional changes
have been investigated in a steelworkers’ body exposed to hot conditions in a
dry subtropical climate. The revealed functional changes have a temperate
character. It has been established that the character and intensity of
functional changes of the workers’ body depend both on the industrial and
non-industrial factors, such as the character and intensity of thermal load,
climatic and geographical conditions of the region, adaptation of the workers
to these factors, the season. The conducted research has laid down a basis of
the measures for work improvement.

genesis of non-specific urethritis (NSU). /G. Maglakelidze; L. Khutsishvili;
The author gives his
views concerning chronic prostatitis. He suggests that the disease is laid down
by virus (or group of viruses) existing in the cell during the embryonic life.
The lifelong effect of virus (or group of viruses) on cells may initiate
different chronic inflammatory processes and different pathologic changes in
the organism, including prostatitis. An analysis of the literature showed a
lack of complete understanding of the causes and mechanisms of chronic
prostatitis, but it also showed that the prostatitis syndrome is no longer a
faceless myth. It is a reality, and the new awareness of its importance may
give new hope for patients suffering from this intractable pain syndrome.
Further research in this area will help to better understand the nature of
chronic prostatitis and find the best possible solutions in its treatment. The
current literature in mechanisms involved in the pathogenesis of
prostatitis/chronic pelvic pain syndrome (GPPS) is reviewed. Based on the
literature and own observation it is suggested that, in the pathogenesis of
chronic prostatitis are involved several mechanisms, and the mechanism of
infection, especially in the later stages of the disease, is not determinative.
Carried out researches give us an opportunity to state that this disease begins
in perinatal period by the group of viruses HSV-1, HSV-2, and cytometagalovirus
infection.

Thyroid carcinoma is the most common primary
cancer of the thyroid gland. The purpose of the study is to find if thyroid
gland carcinoma shows gender predilection in Armenia. 529 cases of thyroid
gland cancer were studied in hospitals from 1999 to 2011. It was found that
thyroid gland carcinoma is three times more common in women than in men
practically in all age groups. In comparison with 1985 year, the frequency of
disease in women has increased. Thyroid gland carcinoma had a higher death rate
in women than in men. The lethality was higher in men.

Thyroid cancer is considered as one of the deadly cancers.
Differentiation of benign and malignant structures is difficult in patients
with thyroid cancer. This work is devoted to the problem of early clinical
diagnosis of thyroid cancer. 523 cases of primary thyroid cancer from 1999 to
2011 were studied. The pathomorphologic analysis of thyroid cancer was carried
out. The problem of early detection of thyroid cancer is reviewed. It is
concluded that the thyroid nodule fine-needle aspirate biopsy and
intraoperative frozen section examination do not allow the accurate
differentiation of benign tumors from malignant neoplasms; novel diagnostic
methods for early detection of thyroid cancer are needed.

Today hyperfraction radiotherapy in combination
with cisplatin and 5-FU is the most effective treatment modality of patients
with nasopharyngeal carcinoma. The poorly investigated late complications
developed as a result of using this method made the basis of this research. By
analyzing the treatment results of 118
patients, we revealed that radiation damages are more often and severe in the
patients subjected to a more aggressive treatment – accelerated hyperfraction
radiotherapy with and without concurrent cytotoxic drugs. However, the
application of complex prophylaxis and treatment measures by radiation
oncologists in cooperation with other specialist (dentists, dermatologists,
endocrinologists, etc.) make it possible to control toxicity and finalize the
planned treatment schedule.

The assessment of adolescent’s reproductive behaviour and
identification of the factors affecting this kind of behavior represented the
main goal of the study. A comprehensive
examination (n=136) and interviewing (n=825) were made in female adolescents
aged 14 to 19 years (randomly formed via continuous selection). Information on the state of their health, their
attitude towards child–bearing and their risky habits have been evaluated.
Under the present conditions, the development of the reproductive system in
female adolescents is characterized by high frequency of menstrual
irregularities (24.7%), the delayed formation of the bone pelvis (25.2%) the
trend for retarded development of secondary sexual characters (12.3%), the high
prevalence of chronic extra genital diseases. Thus, the results of the
given study prove that reproductive disorders develop under the influence of a
complex of socio-medical factors and lifestyle. They predetermine the
reproductive abnormalities, inadequate reproductive behaviour, and the low
standard of knowledge of contraception.

Lately, high rate of swine flu À (H1N1) disease has been recorded in
the world. In Georgia, it began to spread at the end of autumn 2009. The aim of
our study was to define clinical trials of the swine flu (H1N1) in patients of
the Republic Clinical Hospital in Batumi from 2009 to 2011 and to generalize
the methods of treatment. In the hospital, there were 94 patients suffering
from the swine flu (H1N1) disease, 20 of which, due to their critical situation
of the disease, were treated in the intensive care department. We studied case
histories of 20 patients, who were undergoing treatment in the intensive care
department under the generally recognized monitoring programme. Out of 20
patients 10 were women and 10 men. 10 patients died. The intensive care
programme consisted of infusive-transfusive therapy by the negative water
balance, antivirus treatment (Tamiflu/Relenza), de-escalation antibiotic
therapy, mechanic ventilation of lungs, aerosol therapy, plus symptom
treatment. In 2011, there were fewer cases of the swine flu and death rate
compared to the earlier years. In 2011, one out of 25 patients died, but in
2009-2010, 7 out of 69 patients died), which was conditioned by immunity
development. The most frequently used regime of lung mechanic ventilation was
BIPAR. In the first days, the antibiotic therapy is not determining. A more effective

Immunotherapy is considered as one of the promising treatment
strategies for patients with malignant tumors. In the presented work antitumor
effects of E.coli thermo- and phagelysates on Ehrlich carcinoma growth in mice
have been studied. The treatment efficacy was evaluated by estimation of
dynamic changes in volume of cancer tissue and by the percentage of cancer
growth inhibition. Semi-empirical mathematical model, describing cancer volume
variations in relation to time, passed after Ehrlich carcinoma inoculation was
elaborated. It was shown that at the early stage of cancer growth both tested
bacterial preparations significantly inhibit cancer growth. Antitumor treatment
effects were better expressed in animal studies using bacterial pagelysates in
comparison to that of thermolysates. After cessation of administration of
bacterial preparations a prolonged antitumor activity in animals treated with
E. coli phagelysates was demonstrated.

On
cats, we studied the influence of stimulation of the Raphe nuclei (RN) on
postsynaptic processes evoked in neurons of the somatosensory cortex by
stimulation of nociceptive (intensive stimulation of the tooth pulp) and
nonnociceptive (moderate stimulation of the ventroposteromedial – VPM- nucleus
of the thalamus) afferent inputs. 6 cells, selectively excited by stimulation
of nocciceptors and 9 cells, activated by both the above nociceptive and
nonnociceptive influences (nociceptive and convergent neurons, respectively)
were recorded intracellular. In neurons of both groups, responses to
nociceptive stimulation (of sufficient intensity) looked like an
EPSP-spike-IPSP (the letter of significant duration, up to 200-300 ms) complex.
Conditioning stimulation of the RN, which preceded test stimulus applied to the
tooth pulp or VPM nucleus by 100 to 800 ms, induced a 40-60% decrease of the
IPSP amplitude only, while the maximum effect in both cases was noted within
intervals of 300-800 ms between conditioning and test stimulus. During
stimulation of the RN, serotonin released via receptor and second messengers
provides the postsynaptic modulation of GABAergic system, decreasing the IPSP
amplitude, which occurs after stimulation of both the tooth pulp and VPM
thalamic nucleus. This process may be realized through either pre- or
postsynaptic mechanisms.

Radionuclide content
of food and water in high mountainous regions of Georgia - Adjara (Keda,
Shuakhevi, Khulo) has been studied; internal and total irradiation doses for
the population have been defined and preventive measures for its reduction have
been proposed. Internal irradiation dose for the population caused by K-40 was
identified as 0,63 mSv/y, total irradiation dose – 1,73 mSv/y that slightly
exceeds acceptable levels;
due to this it seems desirable to provide some measures with the aim to reduce
the radiation dose of the population and conduct further observation of the
radiation situation. Measures intended to reduce irradiation doses include:
provision of population with less radioactive water sources, the regulation of
medical radiation procedures (mostly - X-ray diagnostic procedures), the
rational use of fertilizers with 40K content, construction of
buildings on the territories with the lowest values of gamma radiation and radon
release from soil, use of materials with low content of natural radioactive
nuclides for building construction, provision of premises with effective
ventilation and radiation monitoring of buildings at any stages of
construction, reconstruction or repair.

These experiments examined the release of glutamate (Glu) and GABA in
the hippocampus of rats treated with memantine (2.5mg/kg, for four weeks) or
saline prior to, during, and after spontaneous alternation test. Glu and GABA
release during the 10 min samples taken at the time of the behavioral testing
of animals treated with memantine or saline were not different from those seen
immediately before and after testing. Similarly, the alternation scores were not significantly different between groups. We
found an increase in KCl-stimulated glutamate and GABA release in the
hippocampus of memantine-treated rats compared to the saline-treated rata. This
difference in KCl response between the memantine-treated and control rats was
statistically significant (p<0,05). Our evaluation of memantine reveals that
changes in KCl-stimulated Glu and GABA release after chronic memantine
treatment do not affect the working memory in adult rats assessed in the
spontaneous alternation task.

of magnetic fields are utilized, although mostly the sick fields are
considered. In spite of some advantages, that possess the sick magnetic fields
in MRI, there may arise some problems being untypical for the ordinary and
strong magnetic fields in MRI. Especially, some differences appear in
inhomogeneous magnetic fields due to the presence of attendant gradients being
transverse relative to the main field. In this paper the mathematical
formulation of the relation between the performed object and the data received
by MRI methods is considered. It is noted as well that the relaxation processes
