Before, during and after total X-irradiation (500 Gy) of anesthetized by nembutal (50
mg/kg) rats the dynamics of cardiac rhithm changes was studied using the original full
automatized monitoring system for digital measuring of R-R intervals and computer
estimation of correlation, covariation, spectral and other parametres, reverberating
functional condition of the heartbeat regulatory system. Large doses of radiation was
shown to result in a phasic disturbance of the nervous regulatory mechanism, especially on
the suprabulbar level with a simultaneous damage to the pace-maker cells in the
myocardium. These changes appeared partly reversible but in the pre- and terminal periods
they recurred. The possible mechanisms of these changes are discussed.

SUPERLETHAL X-IRRADIATION EFFECT ON AGGRESSIVE BEHAVIOUR AND SOME
NEUROCHEMICAL INDICES IN THE BRAIN STRUCTURES OF RATS
M.Nikolaishvili, K.Nadareishvili, G.Jordanishvili, N.Melitauri
The action of X-irradiation (50, 100, 200 Gy) on spontaneous aggressive behaviour of
animals and on their emotional memory in open field, as well as some of their
neurochemical indices were studied. An hour after the total irradiation (3,6 Gy/min) 50%
of aggressive rats have lost their motivation to attack the victim. After four hours 75%
and after six hours all the aggressive rats have turned into nonaggressive. It the same
time changed the rats' behaviour in open field and the distribution of free amino acids in
the cerebral structures. The above-mentioned processes are supposed to be due to the
changes in neurotransmitters and free amino acids.

VASOPRESSIN BLOOD CONCENTRATION CHANGES INDUCED BY NOCICEPTIVE STIMULATION
OF RABBITS BEFORE AND AFTER X-IRRADIATION
N.Gzirishvili
The increase of vasopressin concentration in the blood in response to nociceptive
stimulation was observed. It is considered as the involvement of this system in the
antinociceptive analgesic defence reaction. Exposure of animals to ionizing radiation in
the dose of 4 Gy results in a decrease of vasopressin blood concentration to nociception
and removal of analgesic defence mechanism.

VASOPRESSIN DAILY RHYTHM IN BLOOD BEFORE AND AFTER X-IRRADIATION OF
RABBITS
N.Gzirishvili
Vasopressin concentration in the rabbits blood at 10 pm and 2 am, also at 6 am is
statistically reliable higher, than at 10 am and 2 pm. 8 Gy dose irradiation of animals
results in the disturbance of the vasopressin circadian rhythm in blood. There is no
difference between vasopressin blood concentration in the day- and night-time.

ACTION OF THE IONIZING RADIATION OF THERMAL PROPERTIES AND TRANSPORT
FUNCTIONS OF POLYCELLULAR MEMBRANES
T.Sanaya
The active transport (AT) dose-effect curve of Na-ions was shown to have S-shaped form and
that of K-ions, exponential form. The radiation dose required for the inactivation of the
Na-ions AT is three times greater than for the inactivation of K-AT. The analysis of data
has shown that in the basic membranes of epithelial cells there function two Na-pumps, the
first is oubain-sensitive thermal-sensitive and radio-sensitive Na/K pump, and the second,
oubain-resistant, thermal-resistant and radio-nesistant. The functional mechanisms of
these two Na-pumps are essentially distinct. The possible physiological mechanisms of the
second Na-pump is considered.

THE DYNAMICS OF DOCUMENTARY INFORMATION STREAM AND GENERAL TENDENCIES IN
NEURORADIOBIOLOGY FROM HIROSHIMA TO CHERNOBYL
B.Gugushvili
The analysis of the structure of documentary information stream was made. In 1954-1987 the
transition period is completed and begins the development of problematic directions in the
field of radiation neurobiology. The change is the cumulative volume in subject to
parabolitic dependence. The part of increasing tendency of coauthorship in all thematic
directions is established.

THE STRUCTURE AND DYNAMICS OF INFORMATION STREAMS IN RADIATION CARDIOLOGY
B.Gugushvili
The publications dealing with the influence of radiation on the cardio-vascular system are
to a considerable extent of experimental nature and this tendency is proved on the basis
of scientometric analysis of information stream for the last quarter of the century. This
indicates that a lot of questions in this field are in need of theoretical study using
model experiments. The analysis of the obtained distribution of documentary information
stream shows that it is mainly described by the Zipf-Breadford law.

A NEW APPROACH TO THE RESEARCH OF PERIPHERAL BLOOD ERYTHROCYTES POPULATION
STRUCTURE
G.Ormotsadze
The proposed method based on automatic measuring volume of peripheral blood erythrocytes
(PBE) and functional modelling of the living cycle as well as experimental data obtained
on rates during radiation injury and action of other stressors allow to come to the
conclusion, that: 1) it is possible to obtan an operative and correct approximation about
functional state of the red blood system and its adaptive behaviour during illness or
environment tension; 2) some effects demonstrated by this method cannot be explained by
means of the mechanisms known so far about the red blood system, including PBE aging,
elimination, properties and diagnostic significance of its population spectrum estimation.
The causes of these effects are in nead of further study.

THE MECHANISM OF THE ELECTRON EXCITATION INTRAMOLECULAR TRANSFER IN
ORGANIC COMPOUNDS OF VARIOUS FUNCTIONAL GROUPS
R.Tushurashvili
The nature of radical and ion products which are formed during the radiolysis of organic
compounds of various functional groups has been studied. The dependence of the radical
products type on the length of the hydrocarbon chain and the nature of the functional
group have been recorded. The value of Cn - the number of CH2 - the fragment at which
takes place a change in the nature of the radical product has been established. For the
first time is described the mechanism responsible for the electron excitation
intramolecular transfer which unequivocally explains a dramatic change of radiolysis of
the definite value of the hydrocarbon chain length.

THE KINETICS AND THERMODYNAMICS OF THE X-IRRADIATED PROTEIN MOLECULES
ABSORPTION IN LIPID MONOLAYERS
A.Egiazarova
Effects of X-irradiation on the interaction of proteins (human serum albumin, globular
actin, citochrome c) with stearic acid, cholesterin and phospholipid monolayers were
studied using the monomolecular technique. X-irradiation of protein solutions modifies the
kinetic and energetic parameters of interaction processes, in particular, activation
energy and absorption velocity. It is concluded that these effects are bound with
conformational changes in the irradiated protein molecules, changes in the number of
nonpolar side chains and electrical charges on its surface.

STUDIES OF THE RED BLOOD SYSTEM REGULATION IN NORMAL AND X-IRRADIATED
RATS
G.Ormotsadze
The basic indices, reflecting the functional state of the red blood system including
production, aging and elimination of peripheral blood erythrocytes (PBE) were studied
using an original method, based on the estimatin of cell volume, superficial area and
spherulation rate. Total X-irradiation of rats (7 Gy) was shown to provoke significant
depression of erythropoiesis and aging velocity during the first 1-3 days after radiation
exposure, while the velocity of elimination increases only 4-5 days later at the time when
restoration of erythrocytes production begins.

ACTION OF ACTH FRAGMENT AND RADIATION ON THE RATS' AGGRESSIVE BEHAVIOUR
AND THE DISTRIBUTION OF TRANSMITTER AMINO ACIDS IN THE BRAIN STRUCTURES
M.Nikolaishvili
Study of the influence of ACTH fragment on aggressive behaviour of naturally aggressive
rats has shown that its two-fold introduction provokes a change in the animal's behaviour
and the rats render calm (nonaggressive). Neurochemical experiments revealed that the
metabolism of the amino acids in the cerebral hemispheres has a tendency to an increase of
the ratio of aspartic acid to taurine and GABA with a simultaneous enchancement of
oxidation. Following the injestion of ACTH fragment radiation exposure leads to an
increase in the amount of phenylalanine, cystamine acid, glycine and especially of GABA,
and on the sixth day no alteration in the distribution of free amino acids (FAA) in the
cerebral hemispheres is observed. The exchange of FAA in the hippocampus is going on in
the same way, but the quantitative changes in collicular structures are less pronounced.
The results obtained enable to conclude that fragment 4-7 of ACTH transforming FAA's
normal exchange in the brain structures has a correcting action on aggressive behaviour
and the X-irradiated effects.

In order to exclude the various anthropogenic loading factors the results of experimental
work concerning the content of metals in Georgian soils and the industrial and
agricultural pollution were considered. They were shown to have the local character and to
exert no influence over the epidemiologic characteristics. The comparative analysis of
dynamics of the deathrate caused by tumor diseases, anemias and leucosis and radioecologic
radionuclides in the nature in a number of cases fails to reveal a distinct relationship
with Chernobyl catastrophe, that necessitates its further studies.

On the basic of sciencebasic criteria, with the analysis of documentary information stream
in particular, perspective thematic trends were revealed. The cumulative share of
investigations in English on the utilization of radioactive wastes is twice as much as
those in Russian. The peak of publication in the basic trends: the distribution of natural
