A NEW METHOD FOR STUDYING THE RED BLOOD SYSTEM G. Ormotsadze, K.sh. Nadareishvili
In the framework of systems analysis we have developed a new methodological approach for studying the functional state of the red blood system (RBS), based on the analysis of population spectra (PS) of the peripheral blood erythrocytes (PBE) - distribution of PBE according to their physiological state. The physiological state of erythrocytes with the use of this methodological approach is estimated by two parameters: the cell spherulation degree and their volumes. By a comparative analysis of PS obtained in humans under normal physiological conditions and in different pathologies, as well as in rats under radiation pathologies, consistent changes were revealed in the surface area and volume of PBE in the course of their survival cycle. Based on them, a number of criteria for estimation the RBS functional state were established. Within stationary approximations, on the strength of a single PS analysis, it is supposed to be possible: 1) determination of overall PBE concentration and hematocrit; 2) detection of a variation in the intensity of destruction (rate of aging) and consequently, also the PBE survival and intensity of stochastic perish of cells in respect to physiological norm; 3) estimation of the degree of erythropoiesis by way of distribution analysis of volumes and surface area of young fractions of PBE; 4) evaluation of changes occurring in rheological properties of the circulating blood. In nonstationary (transient) conditions of RBS functioning, dynamics of PS variations allows for practically complete visualization of the process of PBE aging. Key words: RED BLOOD SYSTEM, METHOD, ERYTHROCYTE, ERYTHROPOIESIS, ERYTHROCYTE AGING, and ELIMINATION.
PROBLEMS OF THRESHOLD OF RADIATION EFFECTS IN MODERN RADIOBIOLOGY AND MEDICINE M.S.Tsitskishvili, G.T.Gadelia, G.V.Karchava,A.G.Chkhartishvili, E.M.Petriashvili, L.B.Tsitskishvili, T.M.Suloshvili, V.H.goncharova
Radioactivity detection has fundamentally changed not only the world outlook, but also a way of life, modern biology and medicine. Problems of its safety and regulation are closely connected with the questions of threshold effect. The epidemiological and experimental results of pro and contra of threshold radiation effects are considered in this work. Analysis of materials suggests the presence of threshold effects in small radiation doses. The conclusion is made on the possibility of repudiating the hypothesis on nonthreshold linear effect of atomic radiation; this will not cause significant changes in practical regulation of ionizing radiation, will improve measurement assurance of safe radioutilization in medicine. Key words: SMALL RADIATION DOSES, THRESHOLD EFFECT.
EFFECT OF IMMOBILIZATION INDUCED STRESS ON AGGRESSIVE BEHAVIOR OF ANIMALS AND THEIR NEIROCHEMICAL CORRELATES N. Melitauri, M. Nikolaishvili, G. Iordanishvili
Immobilization of rats induces aggressiveness in 70 % of them. 12 days later after the immobilization the animals lose the aggressiveness. It is remarkable that 7 Gy exposure of immobilized rats causes loss of aggressiveness on the 2 day. There is no noteworthy difference between control and immobilized rats in terms of elaboration and storage of passive avoidance reaction. Although the elaboration of active avoidance reaction in immobilized animals requires more influence. The exposure of immobilized animals causes the decrease of MAO (Mono Amino Oxidase) activity both in frontal and distal parts of the hemispheres. Furthermore, it causes an increase of noradrenaline correlation to serotonin in pineal complex, hippocampus, olfactory bulb and hypothalamus. The exposure of immobilized animals at 7 Gy decreases this correlation and it becomes similar to the control group Key words: RAT, IMMOBILIZATION, FREE AMINO-ACIDS, BEHAVIOUR, PASSIVE AVOIDANCE REACTION, ACTIVE AVOIDANCE REACTION
INTERRELATION BETWEEN Na, K, AND Ca IONS TRANSPORT VALUES AND DNA SYNTHESIS IN THE TUMOR CELLS BEFORE- AND AFTER IONIZING IRRADIATION A.Mtskhvetadze, M.Gogoberishvili
The goal of the work was to determine the relation between the DNA content in the tumor cells, as related to the level of transmembrane transport of Na, K, and Ca ions, in both intact and irradiated conditions at various doses. Experiments have shown increased transmembrane transport of these ions in the tumor cells (sarcoma-37) as compared to the normal fibroblasts. In such a case the content of DNA in the cells is linked with the volume of transmembrane transport of the ions. Ionizing irradiation at a dose of 200 rad suppresses ionic transport of Na, K, and Ca in the tumor cells and, respectively, the DNA content as well. Key words: TRANSMEMBRANE TRANSPORT
GENETIC HAZARD OF IONIZING RADIATION - RETROSPECTIVE ANALYSIS OF THE PROBLEM M.S.Tsitskishvili, G.T.Gadelia, T.S.Zakareishvili, G.V.Karchava, A.G. Chkhartishvili, L.B.Tsitskishvili, B.S.Gugushvili.
Perennial data on the estimation of the genetic danger of ionizing radiation according to official estimation of the United Nations Scientific Committee on the Effects of Atomic Radiation (Official Records of the General Assembly) have been analyzed. Summary tables on the estimation of the “doubled dose” values, as well as numerical evaluations of the mutagenesis frequency values of different origin per 1 mln of newborns have been presented. According to the recent estimations, the frequency of all types of natural mutations per 1 mln of newborns reaches 738 000. On this background an estimation of mutation values by exposure at a dose of 1 Grey – from 3000 to 4700 is more than modest. However, an actual estimation of ionizing radiation hazard by radioecology-anthropogenic loads on the external natural environment increases in terms of some factors: - at exposure of “parent generations” the mutation percent will be doubled; - at high “natural level” of spontaneous mutations the probability of defects “summation” will sharply increase. In spite of the presence of powerful antimutation reparation mechanism in human’s genotype, a further progress in studying the phenotypes of revealing dysfunctions makes it still difficult to estimate genetic hazard of ionizing radiation. Key words: ''REDOUBLED DOSE", FREQUENCY OF NATURAL MUTATION
THE STIMULATORS OF PROLIFERATION IN THE NORMAL CELLS CORRELATED WITH GROWTH FACTORS IN THE TUMOR CELLS IN INTACT AND RADIATED STATES A.Mtskhvetadze, A. Mukhadze
It is known that growth factors affect the active transport of sodium, potassium, and calcium. Therefore the volume of active transport may be used as a criterion of impact of a certain growth factor. The aim of the present work was: 1. To investigate transmembrane transfer of K+, Na+ and Ca2+, and the ATPase activity in cell cultures in both intact state and after the influence of the growth factors (TGF, EGF, IGF), in comparison with the same indices of the tumor cells; 2.To conduct similar experiments after the action of ionizing radiation. Our experiments have shown that TGF, at a higher extent than EGF and IGF, especially by the criteria of impact on the calcium transport, elicits changes in the ZTZ cells, which resemble indices observed in the tumor cells in Sarcoma-37. This notion has been corroborated by the action of ionizing radiation of 500 rad as well. Key words: GROWTH FACTOR, TRANSMEMBRANE TRANSFER.
EFFECT OF POWER-FREQUENCY ELECTROMAGNETIC FIELDS (EMF) ON AGGRESSIVE BEHAVIOR AT EARLY STAGES OF ONTOGENESIS G. Iordanishvili, M. Nikolaishvili, N. Melitauri, G. Magradze, M. Kakabadze, M. Djodjua
The manifestation of mouse-killing aggressiveness during ontogenesis was studied in the offspring of white and gray rats. It was shown that in gray rats the aggressiveness was manifested sooner, at 80-91 days age, when their weight was 145-150 g. While in white rats the aggressiveness was manifested at 100-115 days age. In the offspring obtained by crossing the non-aggressive gray rats with non-aggressive white ones the aggressiveness was manifested in 42,8 % of gray rats and in 20 % of white animals. From the 25 descendants received by crossing non-aggressive gray rats with aggressive white ones, 14 (56 %) were gray and 57 % of them were aggressive. Also in white rats the level of aggressiveness has increased and was 48 %. The study of effects of power-frequency (1,5 mT) EMFs on the manifestation of aggressive behavior has shown that one-hour exposure does not cause induction of aggressiveness in white rats, while 60 % of non-aggressive gray rats become aggressive after the exposure. The study of effects of one hour exposure to 50 Hz frequency at 1,5 mT induction electromagnetic fields on elaborated and stored passive avoidance reaction has shown that right after the exposure the number of rats which remembered this reaction has sharply decreased and reached zero, while in control group it was 82,5 %. The study of EMF effects on elaboration of passive avoidance reaction has shown that it has overwhelming effect on psycho-nervous memory: in non-aggressive rats after exposure to EMF (1,5 mT) the elaboration of passive avoidance reaction does not occurring. And in naturally aggressive rats it had very significant difficulties. Exposure to EMF has effects on “Open Field” behavior of rats as well. The difference is statistically significant for translocations and central circle leaving time, that are 5 times less than in control rats, while the orientation-exploratory activities (vertical rising) and stereotypic activities (grooming) are increased. The study of effects of power-frequency EMFs on distribution of free amino-acids and concentration of mediator amino-acids in brain has revealed the increase of stimulation processes, which are probably eliciting aggressive behavior of animals. Thus, these results corroborate our earlier opinion about the fact that the influence of mediators on the central nervous system is manifested by difficult interrelationships that have different effects on the animal’s behavior. Key words: RAT, IMMOBILIZATION, ONTOGENESIS, FREE AMINO-ACIDS, “OPEN FIELD”, BEHAVIOR, AND PASSIVE AVOIDANCE REACTION
EFFECT OF POWER-FREQUENCY EMF ON RATS’ BEHAVIOR AND THE DISTRIBUTION OF FREE AMINO-ACIDS IN THE CEREBRAL CORTEX M. Kakabadze, L.Tsitskishvili, M.Djodjua
The action of chronic exposure to power-frequency electromagnetic fields (EMF) at the induction of 1,5 mT on the rats’ passive avoidance reaction as well as on the distribution of free amino acids in the cerebral cortex was studied. Statistically significant changes were shown to occur in the distribution of free amino acids after exposure, which manifested themselves with different changes in rats’ emotionality and their ability to learn. Key words: RAT, ELECTROMAGNETIC FIELD, ONTOGENESIS, FREE AMINO-ACIDS, “OPEN FIELD”, BEHAVIOR, PASSIVE AVOIDANCE REACTION
COMPARATIVE STUDY OF ELECTROMAGNETIC RADIATION OF DIFFERENT FREQUENCY RANGES AND IONIZING RADIATION OF DIFFERENT DOSES ON VARIOUS INDICES OF IMMUNE AND HORMONAL SYSTEMS A. Mtskhvetadze, G. Nadareishvili
The effect of electromagnetic field exposure in the frequency ranges from 40 to 60 Hz at 2,0 mT induction, as well as the effect of ionizing radiation at doses of 7 and 10 rad were studied. It turned out that under the conditions of exposure the both factors have a stimulating effect on hormonal and immune systems. During a complex influence of both of the mentioned factors the stimulating effect was greater, than after the influence of each factor taken separately. This may become a basis for the development of a method for strengthening the immunity in oncology practice. Key words: ELECTROMAGNETIC FIELDS, IMMUNE AND HORMONAL SYSTEMS
ABIOTIC FACTORS OF UNNATURAL DEPRIVATION AND IMPRINTING G. A. Marsagishvili, K. Sh. nadaerishvili, V. I. Sandodze, T. I. Gikoshvili, L. d. Jokhadze

EFFECT OF IONIZING RADIATION AND ELECTROMAGNETIC FIELD DURING PRENATAL PERIOD ON THE MEMORY OF RATS L.Tsitskishvili
Chronic influence of electromagnetic field of the network frequency was found to have negative impacts on the nervous system of the germ in the prenatal and postnatal period of development. More specifically, increased excitability of the central nervous system was fixed in the above-mentioned animals in the early period of postnatal development. The first perception stage of memory was violated in the rats. The memory of those rats, which had been subjected to electromagnetic field during the prenatal development period, was also negatively affected. Namely, all three stages of memory were impaired. It is worth noting that similar irregularities were recorded in animals, which were x-rayed with 0.5 Gy beams on the 9th day of prenatal development. Key words: ELECTROMAGNETIC FIELD, PRENATAL AND POSTNATAL PERIOD OF DEVELOPMENT.
MOBILE PHONE (CELLULAR RADIOTELEPHONE).EVALUATION OF THE HEALTH HAZARD L.B.Tsitskishvili, G.T.Gadelia, R.V.Rcheulishvili, T.A.Suloshvili, M.S.TSitSkishvili, G.M.Magradze, Z.S.Sharadze, T.L.Ninua
Cellular radiotelephone that is a great progress of civilization suggests effects of EM radiation on health. Foremost, radiation levels in the organism are limited by absorbed energy. Analysis of literary data and our laboratory studies have not suggested unambiguous data on oncopromoting effects of EM radiations. At the same time, we obtained reliable experimental data on functional changes, according to exposure duration and technical characteristics of EM radiation. At present, a basis of limiting the cellular radiotelephone hazard results from the radiated power control.The main concern of population is an allocation of base stations in residential neighborhood. Worldwide practice in the pilot experimental studies in the places of “transmitters” installations fulfills standard requirements. At the same time, an ambiguity of safety targets determines a World Health Organization to adopt “ Prevention Policy”. Key words: MOBILE FHONE, ABSORBED ENERGY

A growth of X-ray medical procedures associated with the growth of examination rates and elaborated X-ray equipments cause the danger to the excess of population doses. Required regulation of medical procedures by normative documents is based on the modeling of efficient calculated doses. This work suggests a simplified calculation scheme and effective irradiation doses for ten main X-ray procedures in four main age groups that allows estimating the effective doses for irradiating the patients under X-ray examinations. Key words: CALCULATED DOSE

THE INFLUENCE OF GAMMA-IRRADIATION ON THE ACTIVITY OF ALKALOIDS BIOSYNTHESIS IN CULTURAL CALLUS TISSUES M.Gogebashvili., N.Ivanishvili., L.Phaladze., N.Popiashvili
In this work the change of alkaloids maintenance in Datura stramonium L. cultural tissues by gamma-irradiation influence is shown. It is determined that the exposure of 10 Gy in tissues causes the decrease of alkaloids maintenance, and in the interval of 20-40 Gy exposure the increase of the compound mentioned above is seen. In order to activate the alkaloids biosynthesis it is not reasonable to use further increase of exposure. The mechanisms and principles of possible interrelation between the primary and secondary metabolisms are discussed. Key words: IRRADIATION, PLANT CULTURAL TISSUES, ALKALOIDES
THE INFLUENCE OF GAMMA-IRRADIATION ON THE FORMATION OF THE ANTIGENETIC STRUCTURE OF PLANT PROTEIN M.Gogebashvili, L.Pkhaladze, N.Ivanishvili
It has been shown that the antigenic structure of the plant tissues is possible to be used as an effective test-system in order to study the processes determined genetically that are related to the development of tissues. It is concluded that gamma-irradiation is able to influence the formation of the morphogenetical reactions in tissues; namely: the quantitative and qualitative indices of phasespecific Albumens are being changed that points to the altered dynamics of the realization of the genetical programme related to the tissue growth. Key words: PLANT TISSUES, IRRADIATION, PROTEIN, ANTIGENIC STRUCTURE
THE INFLUENCE OF RADIOACTIVE EMANATION ON THE SEEDS OF SUGAR BEET AND OVER THE PATHOGENESIS OF THE FUNGI PHOMA BETAE FRANK. H. Akhalaja
The emanation of the sugar-beat seeds (species Bordo 237) by 10-12 krad, causes an increase of the seed swelling energy by 14,8-16,2% and the ability of swelling by 17,2-18,4%. It reduces the presence of Phoma betae fungi on the seed (9,2-11,4%), improves the growing and developing of the plant and its biometrical indicates of germination. Consequently, 80-100 krad decreases to the minimum (0,2%) the presence of the Phoma betae fungi on the seed; it decreases the energy of swelling by 18,4-8,2% and the ability of swelling by 20,3-11,6%.
