Exogenous Triggering Factor for
the Large Earthguakes
Presented October 5, 1999
Abstract.
The problem
of the distribution of planets and "couple of planets" in the moment
of the origin of the earthquakes for the Caucasus, Turkey-Greece united region
has been considered.
The obtained results enable us
to make following conclusions: if the definite distribution of planets or
"couple of planets" can play a role of the "triggering
mechanism" then for the considered regions maximum and real probabilities of
getting of the planets and "couple of planets" in the definite
sectors are calculated.
One interesting fact should be mentioned here:
some pla-nets and couple of planets create the so-called "prohibited
zo-ne" that is if the planet or couple of planets are in their prohi-bited
zone, the probability of the origin of the large earthquakes is extremely
small.
Key words: earthquake,

Influence of Automatic Behaiour
on Discriminative Learning
Presented by Member of the
Academy T.Oniani, August 2, 1999
Abstract. The experiments were carried out in 4 cats in three
series. First, the animals were trained to perform a conditioned automatic
movement to one feeder. Numbers of trials were 224, 230 and 285 in three cats.
Then a new conditioned instrumental reflex was elaborated to the opposite
feeder. Finally, the trained and control cats were engaged in discriminative
learning tasks. The results demonstrate that behavioural automaticity and
discriminative learning have distinct and contradictory nature. They are based
on memory forms differing by their structure. Attention is not involved in
automatic behaviour but inevitably participates in discriminative learning.
Time duration of automatic behaviour is an important factor determining the
strength of retention in the brain.
Key words:

Cholinergic Control of
Emotional Memory in Rats
Presented by Member of the

Abstract. Possible role of cholinergic input to hippocampus is
considered in cognitive and emotional processes. With an aim to elucidate this
problem influences of septal lesion, acetylcholinestherase inhibitor
(galanthamine), and acetylcholine receptor blocker (atropine) were tested in
Punished Water Drinking conflict test, in adult rats. It was found that septal
lesion significantly decreased shock-induced memory retention, atropine
insignificantly decreased retention time, while galanthamine significantly
increased aversive memory retention. These results corroborate the notion that
hippocampal theta-activity correlates with negative emotions and with
improvement of aversive learning processes.

On Conformational Possibilities
of Poly (L-Glutamic Acid)
Presented September 6, 1999.
Abstract. Conformational
analysis of the (Glu)10 in uncharged and in charged states have been
done in the regular main chain approximation. The electrostatic interactions
have been estimated using three different values of electrostatic constants (e): e=4, e=R (R is a distance between
interacting atoms) and conformationaly dependent values of e for each atom-atom interaction. The last evaluations of e are done accordingly as proposed by our method. The result of analysis
allows us to suppose that the side chain charging changes the conformational
possibility of the (Glu)10 homopolypeptides, making the extendent
helix conformation more preferable relative to other conformations and a- helical conformation as well.
Key words: dielectric

Difference in protein spectrum of studied varieties is little. Glutamine
synthetase and glutamate dehydrogenase activities are higher in roots as
compared with leaves. With plant ageing, while glutamine synthetase activities
decrease in vegetative organs, glutamate dehydrogenase activities sharply
increase, independently from protein amount change. The increase of glutamate
dehydrogenase activities is more significant in roots, indicating the
participation of glutamate dehydrogenase in ammonia assimilation in this organ.

Influence of Constituents of
the Synaptosomal Factor on the NaK-ATPase activity
Presented by Member of the
Academy T. Oniani, September 28, 1999
Abstract.
Fractionation
of the Synaptosomal Factor by HPLC recovered two active fractions that show
influence on the NaK-ATPase activity. One of them is high -molecular-weight
proteinous fraction and possesses ability of elimination the inhibitory effect
of noradrenalin, and the second, directly inhibits the enzyme. This activity was
not observed in preparations obtained after subsequent fractionation of the
activatory fraction by the ion exchange HPLC. Even more, there was prominent
reversed action, particularly, deepening of the enzyme inhibition by the

Lysine Biotransformation
during Secondary Alcoholic Fermentation
Presented by Member of the
Academy G.Kvesitadze, November 6, 1999
Abstract. Lysine conversion products in yeast and wine were
studied during condary alcoholic fermentation. Lysine carboxylic carbons
available in the fermentation medium were shown to be incorrporated in the
yeast biomass. They participate in the synthesis of wine amino- and organic
acids. It has been established that in the process of champagnization
asparagine and glutamic acid are the chief products of lysine conversion in
yeast and wine. Of organic acids glyoxylacid is the basic one in wine. During
secondary alcoholic fermentation lysine carbon skeleton is partially oxidized to
carbon dioxide.
Key words:
lysine, aspartic acid, glutamic acid, yeasts, organic acids, amino acids.

Used Against Grape Moth
Presented by Corr. Member B.
Kurashvili, August 2, 1999
Abstract.
We present
the indices of per hectare ecological load
for preparation used against
grape moth. It is ascertained that per hectare ecological load is much
less when using synthetic piretroids than phosphate-organic insecticides.
Key words: ecological
load, piretroid, phosphate-organic.
P450 where 9 regions of
similarity were observed. 7 regions were found with tomato, and only 2 regions
with the Glycyrrhiza and Catharanthus P450. Among structural
domains two out of four, domains B and D were showing high conservation among
plant P450. These regions of similarity may correspond to conserved functional
regions and should improve our understanding of the evolution of these
proteins.
Key words: cytochrome

Some Data on Normocytes
Physical Indices after Extracorporeal Use of Laser
Presented by Member of the
Academy T. Chanishvili, January 10, 2000
Abstract. Laser radiation acts on membrane and makes its
depolarization. This promotes the release of membrane from toxic agents fixed
on it. On the other hand, during change of erythrocytes structural parameters
laser radiation regulates membrane permeability stimulating active
transformation of iones.

Antioxidating Properties of the
Plaferon-LB
Presented by
Abstract. Plaferon
LB (PLB) is a mixture of biologically active compounds from human placenta
amniotic membrane. Due to its immunomodulatory, antiishemic, antitoxic and
anti-inflammatory properties PLB is widely used in clinical practice. Lipid
peroxidation is a well-established mechanism of cellular injury and this
process occurs in association with certain pathological conditions. Present
study was aimed to investigate if PLB possesses antioxidant properties.
Following products of lipid peroxidation were measured: malondialdehyde (MDA)
and MDA plus 4-hydroxyalkenals (4-HAE). Experiments were carried out with three
types of rat brain and liver P2 membrane
fraction and human plasma: (1) control untreated; (2) incubated with Fe2+
during one hour and (3) treated simultaneously with Fe2+ and PLB for
the same period of time. It was shown that PLB causes significant decrease in
the Fe2+ induced elevated
amount of MDA (but not MDA + 4-HAE). Effect is dose-dependent and is achieved
by the cliPsychology
