Таксономический статус степной гадюки правобережной украины

Author(s): A. L. Baybuz,O. V. Kukushkin,Olena Zinenko / Language(s): Ukrainian Issue: 2/2011

Data on morphological variability of the steppe viper in the Kirovograd region (Right-bank Ukraine) are given firstly. Tentative estimation of the similarity level of the local population and the populations from the Left-bank Ukraine and the Crimea was carried out using methods of the multivariate statistics. Morphological data in line with the results of mitochondrial DNA analysis show that the population in the Kirovograd region belongs to widespread Eurasian species Vipera renardiand morphologically most close to the original populations of the lowland Crimea, Sivash and Forest-Steppe of the Left-bank Ukraine. This could indicate the complicated history of the Right-bank Ukraine colonization by the steppe viper and possible influence of environmental conditions on the vipers’ morphology

Author(s): O. M. Vasyliv,S. O. Hnatush,O. I. Bilyy,V. B. Getman / Language(s): Ukrainian Issue: 2/2011

Desulfuromonas acetoxidans are obligatory anaerobic gram-negative sulfurreducing eubacteria. The influence of different concentrations of iron (III) chloride hexahydrate, iron (II) sulfate and manganese (II) chloride hexahydrate on D. acetoxidans growth and light scattering properties has been investigated. The correlation between biomass accumulation and changes of the cells’ light scattering properties has been as-certained under the influence of the 3d transition metal salts. The maximum of cell distribution curve equaled 0.49 ?m under the influence of all investigated concentrations of iron (III) chloride hexahydrate, iron (II) sulfate and manganese (II) chloride hexahydrate. The highest relative content of cells with maximal size (0.49 ?m) and the largest biomass were observed under the influence of 2.5 mM FeCl3x6H2O and 0.5 mM MnCl2x4H2O. Under the influence of FeSO4 the highest D. acetoxidans biomass was obtained with addition of 2.5 mM metal salt in the growth medium. The highest relative cell content with maximal size was observed under the influence of 0.5–1.5 mM FeSO4.

Влияние низкочастотной вибрации на кислотную резистентность эритроцитов

Author(s): O. I. Dotsenko,A. M. Mischenko / Language(s): Russian Issue: 1/2011

The influence of low-frequency vibration (frequency range 8–32 Hz, amplitudes 0.5 ± 0.04 and 0.9 ± 0.08 mm) on the erythrocytes’ acid resistance was studied. The kinetics of various hemolysis stages was investigated. The time-frequency dependences of the kinetics constants of hemolysis stages were obtained and discussed. It was shown that 8–16 Hz vibration with the 0.5 mm amplitude and 8 Hz with 0.9 mm causes destructive reorganizations of a cytoplasm’s water-protein structure. It leads to decrease in a permeability barrier for a hemolytic agent. As a result of oxidizing stress the vibration in the frequency range of 20–32 Hz causes the modifying reactions leading to the aggregation of cellular proteins and, in particular, the band 3 protein.
