Experimental Study of the Accuracy of Activation Analysis with Neutrons Multiplier
Presented by Member of the Academy N. Amaglobeli, October 8, 2002
Abstract. The accuracy of activation analysis with neutrons multiplier has been studied experimentally. It is mainly determined by the error caused by statistic character of radioactive elements decay. In case of irradiation of one and the same sample in different time-regimes the results of numerous measurements coincide with 0.95 confidence probability. An increase of radiation time decreases measuring error but makes worse the expressiveness of the analysis. Therefore in each concrete case the choice of optimal irradiation time is necessary.
Key words: neutrons multiplier, activation analysis, accuracy of analysis.

Impact of Noises on Frequency Distribution of Daily Mean Temperatures in Georgia
Presented by Member of the Academy B. Balavadze, July 17, 2002
Abstract. Power spectrum characteristics of daily mean temperatures time series of East and West Georgia have been analysed. Influence of unavoidable dynamic noises on frequency distribution of analysed data sets was investigated. Multiple noise reduction procedures was carried out. Regression exponents of power spectrum of original as well as noise free time series were calculated.
It was established that variation of daily mean temperatures in Georgia by their linear characteristics represented itself as coloured (pink) type noise. Antipersistence of these time series were caused by unavoidable additional and dynamical noises. Noise free time series revealed clear persistence, though the process of daily mean temperatures variation remained coloured (black) noise.

Alteration of Peroxidase Isoenzyme Spectra in Grape Varieties of Different Frost Resistance
Presented by Member of the Academy N. Nutsubidze, October 22, 2002
ABSTRACT. Alteration of peroxidase isoenzyme spectra under hardening influence was studied in wintering above-ground organs of commercial Georgian grape varieties. By means of electrophoresis in polyacrylamide gel the opposition between different varieties was established in buds, in slowly moving zone of spectra. In shoots, the most resistant part of plant, the content of slowly moving components was higher than in buds. However in the latter under the influence of hardening the number of rapidly moving ones was increased, what is of great importance for adaptation.

The Intensity of Photosynthesis and Content of Plastid Pigments in the Intervarietal Hybrids of Wheat
Presented by Corr.Member of the Academy G. Nakhutsrishvili, October 1, 2002
ABSTRACT. The photosynthetic activity of leaves and ear, content of the plastid pigments, photoassimilates transport and respiration of hybrids obtained by crossing the local varieties of wheat (Triticum aestivum, L. var. Doli 35-4, Tetri Ipkli) with complex hybrids (Tbilisuri 7, Tbilisuri 10, Mexican Triticale) has been studied, in relation with the productivity. In obtained hybrids in some cases the photosynthesis and the content of pigments was lower, compared with the parent forms, respiration was increased. But the indices of their productivity were the same or higher than of initial forms. According to the obtained results it may be supposed that the photosynthesis and pigment content are not in direct relation. These data together with the respiration from their side, are not responsible for the productivity, but affect it and totally may be used for evaluating the productivity of new hybrid. The data of assimilates transport provide also interesting information for studying the plant productivity.
Key words: photosynthesis, plastid pigments, respiration, assimilates transport, hybridization, wheat.

Abstract. The samples of thyroid parenchyma were studied by histologic and electron-microscopic methods after operation causing diffuse and polinodous toxic goiter. It has been concluded: 1) In polinodous toxic goiter (PTG), contrary to diffuse toxic goiter (DTG), "T3-toxicosis" is revealed; 2) In DTG hyperplasia of epithelium is diffuse, it spreads regularly all over the gland while in PTG it is focal, located in certain parts of goiter from which nodes develop; 3) Contrary to polynodous goiter, in diffuse goiter the area occupied by membranes of granular endoplasmatic reticulum is increased. Diffuse goiter is characterized by numerous secondary lysosomes with the properties of hydrolytic activity such as membrane ruptures, by their transformation into the stage of autophagic vacuoli.

Variation of Iron and Copper Concentrations in Placenta at Term and Preterm Delivery
Presented by Corr. Member of the Academy T. Dekanosidze, July 17, 2002
Abstract. The aim of this study is to quantify the essential trace elements iron and copper in placenta. The concentrations of iron and copper have been determined by emission spectrography in 30 parturients at term and 50 parturients at preterm delivery. The present results show that the mean concentrations of iron and copper in preterm parturients are significantly lower when compared with term parturients. It is supposed that low iron (Fe) and copper (Cu) levels in placenta at preterm delivery may be one of the causes of changes in free radical defense mechanisms.

Echocardiography Potential in Prognosis of Hypertrophic Cardiomyopathy
Presented September 10, 2002
Abstract. The aim of our investigation was to determine the main echocardiographic predictors of flow and outcome for patients suffering with hypertrophic cardiomyopathy. 58 patients in accordance with outcome were divided into three groups: with stable flow of disease, with sudden death, with fatal outcome, which was not related with sudden death. Our investigation showed that extreme thickening of left ventricular myocardium and concentric type of left ventricular hypertrophy significantly determines risk of sudden death. Enlargement of left chambers cavity and growth of left ventricular mass is malignant prognostic sign of hypertrophic cardiomyopathy. Severe diastolic disfunction and changes of systolic function is important echocardiographic sign for heart failure and fatal outcome.

Presented by Member of the Academy N. Kipshidze, December 31, 2002
Abstract. 63 patients aged from 15 to 57 (35 males and 28 females) suffering from PRAVNT have been treated. Successful results were achieved in different cases.
It can be concluded that CRA of the slow pathways of the atrioventricular junction is a highly effective and safe method of radical treatment of patients with PRAVNT.The AHBe - ACsp interval measuring shorter than 20 ms during an invasive electrophysiological study indicates to a close proximity between the slow and fast pathways of the atrioventricular junction, therefore demanding extremely care while performing catheter ablation. This criterion derived from our studies will make it possible to minimize the risk of development of a full atrioventricular block.

Ecophysiological Peculiarities in Trifolium ambiguum in Subalpine Zone of the Central Caucasus
Presented by Corr. Member of the Academy G. Nakhutsrishvili, October 15, 2002.
Abstract. In order to determine ecophysiological mechanisms of adaptation to the alpine environment in various phytocoenoses of subalpine zone of the Central Caucasus, diurnal dynamics of CO2-gas exchange and its dependence on ecological factors, biomorphological parameters and content of plastid pigments in Trifolium ambiguum, which has wide synecological area of distribution, have been studied. It has been established that in different conditions this species is characterized by strong variability of the studied indices. Despite strong plastic character of CO2-gas exchange (frequent depressions of net-photosynthesis are marked), it is distinguished with high productivity of photosynthesis (conditioned by high intensity of photosynthesis), high efficiency of CO2 assimilation, high light-requiring, wide range of optimal temperature for photosynthesis and absorption ability of CO2 to high and low temperatures. All this provides its wide spread and plays an active phytocoenotic role in various communities.
