Description
The problem of environmental contamination by heavy metals is significant problem of urbanization. The search of ways of indication heavy metals pollution becomes actual, because of their simplicity and affordability. A widely used test objects for heavy metals pollution indicators are leafy mosses used for bioindication, because they are highly sensitive to any stress factor. The research shows that bioindication with using leafy mosses as test objects is highly effective method definition of heavy metals pollution. Using of bioindication methods are promising techniques for the assessment of the contamination of ecosystems by heavy metals. Through the use of this method, it is possible indication of pollution of the surface layer of air with heavy metals. The epiphytic moss (Pylaisia polyantha) growing in different zones of the city of Rostov-on-Don, was used for the heavy metals pollution biomonitoring of urbosystems. The accumulation features of heavy metals in the epitaphic pylaisiella moss (Pylaisia polyantha) in the territory of the city of Rostov-on-Don have been considered. pylaisiella moss (P. polyantha) accumulates the largest amounts of the following heavy metals: Zn, Cr, Pb, Sr, Ni (Kc to 1.07), and Cu. According to the Kc values, all the studied elements accumulated by pylaisiella moss form the following series of biological uptake: Zn > Pb > Sr > Cr > V > Ni > Cu > Cо. The results of investigation showed that the epiphytic moss (Pylaisia polyantha) can be used as indicator of heavy metals pollution in different polluted zones

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

NEW APPROACHES TO REHABILITATION AFTER ECTOPIC PREGNANCY
Description
The work includes the clinical comparative analysis of ectopic pregnancy’s mortality cases caused by he-morrhagic shock and near miss. Current results contain morphological changes in the adenohypophysis which depend on the amount of hemorrhage and determine the direction of rehabilitation measures in a group of patients who experienced hemorrhage shock

Description
The accumulation features of radionuclides in the epitaphic pylaisiella moss (Pylaisia polyantha) in the territory of the city of Rostov-on-Don have been considered. The specific activities of 137Cs, 226Ra, 40K, and 232Th in the samples of moss, soils, and aerosol air have been compared. The capacity of Pylaisia polyantha to accumulate radionuclides has been estimated for four radionuclides (137Cs, 226Ra, 232Th, and 40K) with consideration for the background level. On the basis of radionuclide analysis, zones in the city of Rostov-on-Don with the highest accumulation coefficients of 137Cs, 226Ra, 40K, and 232Th were revealed. These were primarily the zones with both industrial and traffic loads and the motor transport zones

Description
While studying the content of hypoxia-inducible factor 1-alpha and vascular endothelial growth factor in the tumor tissue, oral fluid and peripheral blood of 141 patients with oral mucosa cancer T1-3N0-2M0, it was shown that the development of purulent inflammatory postoperative complications in patients with oral mucosa cancer is associated with an increased expression of HIF-1α in the tissue and its translocation from the cytoplasm to the nucleus, activation of the neoangiogenesis processes. It is informative to determine HIF-1α factor in the blood serum, which, for further development, can be used as a non-invasive diagnostic marker to predict the postoperative course in this category of patients
