Quantity and quality of erythrocytes, blood haemoglobin concentration, glucose levels in the erythrocytes and plasma, content of TBA-active products in blood plasma of rats were studied during development of the Guerin carcinoma, introduction of cis-platinum and cluster rhenium substances with organic ligands. It was shown that rhenium substances had essential antioxidant effects and changed the dynamic of tumour growth. The conclusion on perspectiveness of further investigations of rhenium substances with cluster fragment and organic ligands in experiments in vivo with changed redox-status of an organism was drawn.

The biotesting of south chernozem soil in Odessasteppe area was made with use of bacterial test-system Salmonella typhimurium TA 100. Comparison of results of biotesting and soil chemical analysis, results of laboratory experiment and multivariate analysis of variance allowed revealing the factors, which are usually hidden but generate genotoxicity potential of soil. Furthermore our research permitted to explain the mechanisms of cumulative effect occurrence under cooperative effect of heavy metals mixture of CoSO4 and FeSO4, CoSO4 and CuSO4.

Frequency of bryophytes occurrence in epiphytic communities of broad-leaved forests of Vorskla River valley and their ecology-biologic peculiarities are analysed. Distinct relations of bryophyte species to specific wood species are not found, while some species, i.e. Hypnum pallescens (Hedw.) P. Beauv., Platygyrium repens (Brid.) B. S. G., Bryum subelegans Kindb. are attached to Quercus robur L., but Radula complanata (L.) Dum., Leskeеlla nervosa (Brid.) Loeske and species of the Anomodon genus − to Fraxinus excelsior L.

Data of the long-term research of accumulation and distribution 137Cs radionuclide in organisms of predatory wild animals from the alienation zone of the Chernobyl nuclear power station are presented. Essential fluctuations of the 137Cs contents in muscular tissue are noted. The results have large practical value for management of the hunting facilities on the radioactively polluted territories.

The effect of exogenous amino acids on the biosynthetical activity of 2P-15 rifampycin -resistant strain was studied. Addition of the amino acids to the medium for the 2P-15 cultivation in the optimal concentrations (50, 100, 200, μg/ml) entailed the augmentation of a synthesis of protein, biomass, activity of staphylococcus-lytic enzymes and strain’s productivity in the conditions of deep fermentation. All studied amino acids ensure the increase of stimulating activity of the mutant 2P-15 strain 2.0-3.7 times.

Dynamics of the basic rhythms of hypothalamogram under conditions of stress and action of the right- handed and left-hand vortex pulsed magnetic fields was studied. Ambiguous influence on both various activities and different zones of hypothalamus was revealed. It may be a result of the specific action of anterior and posterior zones of hypothalamus during the stress-response, and of the mechanism of separate waves generation.

From the position of systems approach the universal principles of phytosystems organization and their hierarchical subordination are examined. Biological quanta are determined for the basic levels of phytosystems organization. A concept “phytocyclocenon” (elementary seral system) is introduced. The legitimacy of its consideration as a basic evolutionary unit of phytocenosystem level of organization is grounded.

The functional state of Greco-Roman wrestlers of high-level skill was studied. 19 sportsmen of 18–27 years old, which are members of the national Ukrainian team, were examined. During the training session the raise of information processing speed with simultaneous enhancement of the homeostasis stress are accompanied by activation of the sympathetic and parasympathetic parts of nervous systems.

Influence of the industrial air pollution on traits of Catalpa bignonioides Walt. fruiting has been studied. The fruiting quality of C. bignonioides plantsbecame worse under environmental contamination by emissions of pipe factory and motor transport. The coefficient of fruiting was reduced owing to diminution of the fruits quantity. Moreover the dimensions and form of fruits changed.

On the basis of field research characteristics of the brown hare track activity in steppe forests of a south-east of Ukraine on the snow cover are presented. The estimation of qualitative and quantitative parameters of the aggregate of the hare vital activity traces as elements of an information field was carried out

The influence of different environmental factors on growth and pigment biosynthesis by particular strains of purple thiobacteria was investigated. These strains belong to the genus Chromatium, Thiocystis, Thiocapsa and Lamprocystis and were isolated from Yavoriv sulphur mine. Calcium, magnesium, manganese, iron and sodium chloride should be included in the medium for optimal growth of these bacteria. Addition of these elements entails increasing the biomass production and synthesis of carotenoids and bacteriochlorophyll a. Initial concentration of inoculum and electron donor has essential influence on growth of purple thiobacteria. Early in the development of culture, sulphide was oxidized, and then the growth impairment and destruction of cells under exposure of light were observed. For the optimization of bacteria growth the electron donor (sulphide) must be added many times during the cultivation process in the concentration, which is not exceed an inhibition dose. The additional bringing of the electron donor in the medium promotes the raise of cells’ biomass. The acetate introduction in the medium has positive influence on the pigments’ biosynthesis. The essential factor of growth and pigments’ biosynthesis is the light intensity. Peak gain of the culture growth was observed under 400 lx. The amplification of light exposure is accompanied by the decrease of growth and content of pigments in cells. Oxygen inhibits the synthesis of pigments in all strains

Comparative morphobiological analysis of the roach Rutilus rutilus (Linnaeus, 1758), living in littoral and open deep-water zones of the lake Plescheevo, was carried out. Different ecological forms of fish were found: littoral and pelagic. They vary in a number of plastic characteristics, morphofunctional parameters (gape size and body form) and in growth rate. We assume that intrapopulation differentiation of the roach was induced by invasion of the zebra mussel into the lake.

The hums of a pharynx, which were originated in the attempt to make "a white noise", were explored in health and disease. To obtain the frequency spectrum the registered sounds were subjected to Fourier’s transformation. It has been shown that the noise spectrum was submitted by peaks reflecting the individual singularities of a human pharynx. On the average men have low-frequency 2−8 peaks, which is more than women (2-6 peaks of higher frequency). Diseases of the throat change peaks’ amplitude, alter its maximums (increasing or decreasing of frequency). It has been also observed the "spreading" of peaks on a spectrum or even complete depressing. The data argue for the possibility to identify a person by a spectrum of hums of the throat or to diagnose illness or process of convalescence objectively.
