Abstract. The transition from potentials to field strengths in

density operator in terms of the electrical and the magnetic specific
polarization operators. It is important that the current density J is expressed
by vectors P and M, which are the quantum-mechanical averages of the

Influence of Acidic Rains on the Activity of Plant
Endogenous Growth Regulators
Presented

Abstract. We studied the effect of artificial acidic rains on
the activity of endogenous growth regulators of the following plants: red beet
(Beta vulgaris L, ssp esculenta),onion (Allium cepa L), carrot-(Daucus
sativus (hoffm) Bochl), coriander (Coriandrum sativum L), kidney
bean (phaseolus vulgaris L, savi), dill (Anethum graveolens),maize-
Zea mays L. It was revealed, that acidic rains cause activation of auxin
group substances in the sprayed leaves of onion, bean and maize. Comparatively
high level of inhibitors was found in sprayed variants of beet, carrot, dill
and coriander. In underground parts of beet, carrot, onion and in seeds of bean
the difference between sprayed and control variants was not observed. Distinctions
in results may be explained by the differences in acidic salts uptake and
accumulation, affecting period and plant’s biological peculiarities. It
indicates different mechanisms of adaptation to acidic rains in plants.

The Effect of Interchain Disulphide Cross-Link in the

Presented
May 4, 1998
Abstract. The effect of interchain
disulphide cross-links and blocking of cystein-190 in the rabbit muscle
tropomyosin molecule on the potentiation of actomyosin contraction by
tropomyosin has been studied. The disulphide crossband between tropomyosin a and b subunits changes tropomyosin conformation in the way
that weakens F-actin - tropomyosin interaction; the blocking of cystein-190
causes the losing of polymerization ability; the cooperativity of Ca2+
regulation of actin-myosin interaction by troponin-tropomyosin complex
diminishes.
We have shown that interchain disulphide
cross-links and blocking of cystein 190 in tropomyosin molecule doesn’t effect
the potentiation of actomyosin contraction by tropomyosin. The conclusion was
made that the districts responsible for the tropomyosin participation in Ca2+
-regulating mechanism and activation of actomyosin contraction in the
tropomyosin molecules must be different.

Investigation of Blood Lipids and Fatty Acids in

Presented

Abstract. Quantitative alterations and lipids’ peroxide
oxidation (LPO) of the human blood phospholipids, cholesterol, and fatty acids
have been investigated in healthy donors and patients with benign prostate
hyperplasia (BPH) and prostate adenocarcinoma (PAC). It was found that in the
blood of the PAC patients an overall volume of phospholipids and of
amine-containing and choline-containing phospholipids was sharply increased. In
both pathologies an increase of cholesterol and activation of the LPO was
evident, although in the malignant tumors these indices were higher. As to
fatty acids, in PAC a sharp decrease of oleic and palmitic acids was
determined, while stearic, linolenic, and arachidonic acids’ volume was
increased. All these data point to the systemic character of the tumor action.

Dynamic Regulation of Light Absorption in Plants
during Stress and Acclimation
Presented
by Corr. Member of the Academy T. Zaalishvili, May 31, 1999
Abstract. After low-temperature stress and rewarming, if the
stress-induced damage is not irreversible, a noticeable increase of delayed
thylakoid fluorescence is marked compared with the level prior to stress. It
indicates temporal depression of photosynthesis dynamic regulation mechanism,
while the thylakoid membrane can still produce the transmembrane gradient of
protons. Dynamic regulation mechanism depression must have been induced by the
dehydration factor of low-tempetarure stress. The mentioned mechanism is very
sensitive to this factor. After cold acclimation of the plant the
low-temperature stress causes neither temporal depression of dynamic regulation
mechanism nor intensification of delayed fluorescence.

Synthesis and Antitumor Properties of
Ferrocenyl-1-phenyl-1-dioxy-1,4-butin-2 (FC-A)
Presented
by Corr. Member of the Academy D. Ugrekhelidze, June 25, 1998
Abstract. In the present work, we stated a technique of
synthesis of ferrocene-containing acetylenic alcohol (FC-A). We investigated
also its biological activity and kinetics in blood. It was established, that
FC-A has certain antitumor properties.

Influence of 3,4-diketoadipic Acid on Respiratory
Processes
Presented
by Corr. Member of the Academy L. Khananashvili, October 3, 1998
Abstract. The influence of 3,4 - diketoadipic acid on
respiratory processes of intact Saccbaromyces cerevisiae cells have been
studied. It has been shown that intensification of respiration occurs in a few
minutes after adding 3,4-diketoadipic acid.

Biological Damages of Fluoro-Containing Materials with
Mould Fungi under Humid Subtropical Conditions
Presented
by Corr. Member of the Academy N. Aleksidze, April 5, 1999
Abstract. Biological stability of 16 samples prepared on the
basis of poly-tetra-fluoro-ethylene has been studied in the humid subtropical
conditions. The 2/3 of the studied material revealed the damage force 3 and
more by the mould fungi, which refers to their biological instability in the
above stated conditions. The experiments have shown that in the humid
subtropical conditions the major bio-destructor of the material is Trichoderma
to be observed on the surface of all materials. Cladosporium and Fusarium
were less frequently observed.

Heart Trophic Ultrastructural Basis under Experimental
Hypercholesterolemia
Presented
by Member of the Academy N. Javakhishvili , March 29, 1999.
Abstract. We have studied ultrastructural-functional changes in
the heart from an early period of atherogenesis (14 days) to its late period (6
months) in rabbits hypercholesterolemic model. The results revealed that
morphofunctional changes in microcirculatory network of the heart are caused by
degenerative changes in capillary endotheliocytes, fibroblasts collagen and GAG
production. Such alterations as a whole result in the profound changes in
myocardiocytes structure and function and development of diffused small focal
cardiosclerosis.

Barrier Function of Red Formed Elements of Blood and
Thrombocytes during Gunshot Wound
Presented
by Member of the Academy T.Chanishvili, September 16, 1998
Abstract. Structural and functional changes in red formed
elements of blood and trombocytes may serve as objective criterion for the
estimation of wound degree, which helps to elaborate proper tactics.

Presented
by Corr. Member of the Academy A. Gvakharia, May 25, 1998
Abstract. The author proposes that a proverb is a
general-referential utterance, but not all general-referential utterances are
proverbs.

The First Book about Charles Darwin and his
Evolutionary Theory by Georgian Author
Presented
May 15, 1998
Abstract. The first book by Georgian author about Charles
Darwin and his evolutionary theory was published in 1914 in Tbilisi. The author
was a famous doctor and charity-monger D. Akhvlediani. The book has not only
chronological, but scientific importance. The author gave suitable
interpretation to Darwin’s teaching.

On the Problem of Creation of Superconductor
Gravimeter
Presented
by Member of the Academy B.Balavadze, September 15, 1998
Abstract. On the basis of the historical and information
analysis, using the scientific and technical potential existed in low temperature
physics and gravimetry in Georgia, the possibilities of both the development of
superconductor gravimeter and the cryogenic gravimetric investigations are
studied.
