On Reliability of Active Elements Working in Regime of
Negative Differential Conductivity
Presented
by Corr. Member of the Academy A. Khelashvili, December 28, 2000
Abstract. We have evidently calculated
field dependence of free electrons' concentration under the existence of
Coulomb barrier in approximation of quasi-elastic scattering in crossed
electric and magnetic fields when effective cross-section of the capture along
with Zomerfeld multiplier exponentially depends on the energy of electron
tunneled through the barrier. The influence of this exponential multiplier and
magnetic field on the electric field corresponding to the minimum of free
electrons concentration are calculated. For rising of active elements'
reliability it is advisable to work in relatively weak electric field.

Impact of Nonperiodic Components in Dynamics of Water
Level Variations in Boreholes
Presented
February 20, 2001
Abstract. In present study dynamic
complexity of water level variations has been analysed. Dependence of dynamics
on the presence of periodic components in considered data records (time series)
was investigated. Modern tools of time series analysis such as Lempel-Ziv
complexity measure (LZC) and singular value decomposition (SVD) technique have
been used. Values of LZC of original and SVD reconstructed water level records
before and after Spitak and Racha earthquakes were analysed.
It was shown that dynamic complexity of
water level variations is caused by nonperiodic components of time series and
is insensitive to the exclusion of periodical influences corresponding to the
three main principal components.
Key words: dynamics, water level variations, complexity measure.

Presented
by Member of the Academy T.Oniani, April 25, 2000
ABSTRACT. Glutamate, asparagine, GABA (g-aminobutyric acid), glycine, proline do not influence
Na,K-ATPase obtained from rat brain either separately or with specific protein
in synaptic cytosol – synaptosomal factor (SF), while Na,K-ATPase activity
changes under the influence of noradrenaline, serotonin, dopamine and
adrenaline. The latter, in its turn, is regulated by the SF. It is supposed
that there are two different mechanisms of neurotransmitters action in synaptic
transmission with the participation of Na,K-ATPase, which, in its turn, should
be concerned the action of some secondary messengers and without Na,K-ATPase,
what may be due to the action of neurotransmitters on ion channels.

Effects of Galanthamine and Atropine on Short-Term
Memory in the Rats
Presented
by Member of the Academy T.Ioseliani, March 28, 2000
ABSTRACT. The effects of
acetylcholinestherase inhibitor substance (galanthamine) and muscarinic
cholinoreceptor blocker (atropine) on the spatial delayed reaction were
investigated in the adult Wistar rats. It was found that galanthamine causes
improvement of the short-term memory. This action should be due to the
cholinergic transmission facilitation, which, in its turn, is involved in the
short-term memory mechanisms. Along with this it is possible that galanthamine
enhances the rate of anxiety, increases the excitability and facilitates
excitation reverberation in the CNS. On the other hand, atropine administration
seriously impaired the delayed reactions owing to the blockage of cholinergic
receptors and to the other side-effects, which accompany the atropine action.

by Member of the Academy T.Oniani, March 14, 2000
ABSTRACT. The purpose of this study was to
map efferent projections from basolateral part of amygdaloid complex to medial
nucleus (MN). Single unit responses were recorded in the MN following
electrical stimulation of the basal and lateral nuclei (BN, LN) in
unanaesthetized, immobilized cats. The LN stimulation influenced 23 (33.8%) out
of the 68 units, whereas to BN stimulation 59 (49.476%) out of 119 units being
found. The most effective sites for influencing on MN cells were located in
parvicellular part of BN. Following stimulation single cell recordings in the
MN showed two basic types of response. The 58% of the cells studied responded
with excitation and others showed a suppression of discharge. Latencies to
first spike ranged from 16 to 68 msec when the LN was stimulated and from 5.3
to 54 msec when the stimulating electrodes were located in the BN. The
possibility of mono- and polysynaptic connections from basolateral amygdala to MN
was discussed.

ABSTRACT. Applicability of the P.aeruginosa
specific phage in phage titer increasing reaction (PTIR) has been established.
By means of this method rapid (within 5-18 hours) detection of respective
bacteria is possible, even in the presence of other microflora and regardless
the concentration of the material under study. Common bacteriological analysis
requires no less than 3 days. The PTIR is efficient even in those cases when
bacteriological analysis does not reveal and identify the pathogenic agent.
With the aim to test the PTIR efficiency total of 70 clinical samples (blood,
urine, pus, wash-down from various objects) were investigated. Analysis of the
data obtained has shown that the number of positive responses in the PTIR
investigations 2-4-times exceeded those obtained by the microbiological
examination. Results of investigation allow to recommend the indicator
pyocyaneus-bacteriophage as the rapid means for diagnostics of P.aeruginosa.
Key words: bacteria, identification, bacteriophage, phage titer,
PTIR method.

The Caucasian Product Matsoni: its Bacterial
Composition and Properties
Presented
by Member of the Academy T. Chanishvili, February 1, 2000
ABSTRACT. In the 1960s and 1970s when
microbial identification was based on traditional microbiology methods Matsoni
was equated to Bulgarian yogurt which is composed of Lb. delbrueckii ssp.
bulgaricus (i.e Lb. bulgaricus) and St. thermophilus (with the ratio
1:1). Due to modern methodology it was shown that by bacterial composition
Caucasian Matsoni remarkably differs from the Bulgarian yogurt. It is composed
of Lb. delbrueckii ssp. lactis and St. thermophilus (with the
ratio 1:3). Probiotic effect of the endemic Caucasian product Matsoni is
determined by Lb. delbrueckii ssp. lactis. According to the preliminary
results antagonistic Lb. delbrueckii ssp. lactis produces exogenic
inhibitory agent that is active against great variety of bacteria such as
pathogenic species of Staphylococcus, Streptococcus, Enterococcus, Ps.
aeruginosa, E. coli, Salmonella and yeast like Candida lucitaniae which
is a common contaminant of dairy plants.
Key words: lactic acid bacteria, dairy starters, bacterial
antagonism.

by Corr. Member of the Academy G.Nakhutsrishvili, January 25, 2000
Abstract. The causal agent of wheat yellow
rust, Puccinia striiformis West f. sp. tritici Eriks, was developed
everywhere in Georgia during 1987-1998. The most wide-spread pathotype is 6EO
(83%) with genes for virulence pp6, pp7. The virulence structure of the
pathogen in Georgia, Armenia, Azerbaijan were similar. This allows to conclude
that the pathogen population in the Transcaucasus is a unit.

Effect of Constant Magnetic Field on the Organizm of
Guinea-Pigs
Presented
by Corr. Member of the Academy V. Mosidze April 1, 2000
Abstract. The exposure of 300 E constant
magnetic field results in the structural and morphological changes of the
peripheral blood and the brain cells in guinea pigs. These deep changes must be
due, on the one hand, to the effect of magnetic field directly on the
hipothalamo-hypophysic system (causing damage to the blood-forming organs) and
on the other hand, to the feedback effect of blood-forming organs on the brain
cells.

Determination of Carcinogenicity on the Basis of the
Theory of "Two Synkaryons"
Presented
by Member of the Academy N.Javakhishvili, February 29, 2000
Abstract. Those substances and influences,
which induce somatic cells fusion (and cell membranes’ perforations) are
probably potential oncogenic agents. Positive fusogenic effect (i.e. appearance
of two- and polynuclear hetero- and homokaryons) of all known carcinogens with
negative control tests, in our opinion, may be confirmed by this mechanism (
fusion) of malignization and also may allow using this method for determination
of carcinogenicity of chemical substances.
Key words: carcinogenes, fusion, erythrocytes, electron
