The article is devoted to biography of Leonid Grinevetskiy (1853-1892) - a medical officer, alumnus of Imperial military-medical academy, first commander of Anadyr region on Chukotka. The article presents the characteristic of activity of the talented medical researcher, Russian scientist and administrator.

[Immunological studies of peripheral blood in patients with external genital endometriosis and infertility]. / Immunologicheskie issledovaniia perifericheskoi krovi bolnykh naruzhnym genital'nym éndometriozom, stradaiushchikh besplodiem.

Immunoregulatory lymphocytes of SD2-, SD4-, SD8- and SD2-phenotypes have been assayed using monoclonal antibodies in peripheral blood of infertile women with external genital endometriosis and tubal-peritoneal infertility. The tested cells did not markedly differ from those in control fertile patients. Serum concentrations of immunoglobulin M were increased in women with endometriosis. Immunoglobulin concentrations widely varied in the peritoneal fluid, with a statistically significant elevation of IgA and IgM in women with tubal-peritoneal infertility.

[Regulation of free radical oxidation of pulmonary surfactant lipids]. / O regulatsii svobodno-radikal'nogo okisleniia lipidov legochnykh surfaktantov.

Surface-active substances of lung tissue, covering the alveoli, resembled the biological membranes in their structure. Their composition was controlled, among the other factors, also by free radical oxidation reactions. Under conditions of circulatory hypoxia the activity of antioxidative enzymes correlated with the alterations in antioxidative activity, with the rates of spontaneous and inducible lipid peroxidation in lung surfactants. As surfactant exhibited a limited antioxidative activity important for resistance of alveolar pneumocytes, their functions may be controlled by various exogenous antioxidants.

[Antiradical protective systems in the plasma membranes of an irradiated animal]. / Sistemy antiradikal'noi zashchity plazmaticheskikh membran v obluchennom organizme.

In the purified plasma membranes of rat liver the antiradical protection systems were revealed involving superoxide dismutase, glutathione peroxidase, glutathione reductase, lipid-dependent and water-soluble catalase, and reduced glutathione. Early changes were observed in these systems after total-body X-irradiation (LD50/30). The authors discuss the role of a plasma membrane in the radiation response of cells.
