BIOLOGICAL PROPERTIES OF BLACK LEACHED SOILS OF THE ROSTOV REGION
06.00.00 Agricultural sciences
DescriptionThe regularity that increases biological and enzymatic activity with increasing the age of the deposits of 10 to 82 years has been shown. The indicator of recovery of black leached soil steppes can be presented as invert-ase activity and humus content, as well as reducing the density of the soil. Integrated indicator of the biological properties decreases with decreasing age deposits: 82 years (100%) - 26 years (84%) - 16 and 10 years (74%) - arable land (64%)

Description
The article describes the structure of microbial communities in urban soils of Rostov-on-Don. The difference in numbers of bacteria of main trophic groups between the central part and the suburbs of Rostov-on-Don has been analyzed. The comparison with control soil with minimal anthropogenic impact has been performed. The indices of mineralization, oligotrophy, oligonitrophylic and pedotrophic quotients have been calculated

Description
The number of microarthropods in the black soil de-creased with an increase in the number of oil. The same pattern was observed until a certain concentra-tion of lead in soil (von 250 mg / kg), after which high doses (500 and 1000 mg / kg) was recorded an in-crease in the number of microarthropods. Gamasid mites and ticks of akaroid-trombidiform complex have proven more resistant to lead, and armored mites and springtails - to oil, vise versa

INFLUENCE OF MALIGNIZATIONS LEVEL OF ASTROCYTIC HUMAN BRAIN TUMOR ON THE EXPRESSION OF CONNEXIN-43
DescriptionStudy was performed on 12 samples of astrocytic human brain tumors, which differ by the level of malignancy and histological indications. The study was conducted with the method of immunohistochemistry using a commercially available antibody anti-connexin-43 (Cx 43), a prior test of which was carried out on myocardium tissue of rats (positive control). The study showed that with the increasing of malignant level of astrocytomas, there was marked the decreased level of connexin-43 expression of, which is apparently to be associated with the destruction of intercellular gap junctions in tumor tissue
