[Lymphocytes sensitization to insulin in acute ischemic attacks].

The study aimed at investigation of frequency and character of lymphocyte sensitization to insulin in patients with acute disturbances of brain blood circulation (ADBBC). Fifty patients with ADBBC (38-with ischemic stroke, 5-with hemorrhagic stroke, 7-with transient ischemic attacks), 17 patients with cerebrovascular diseases (CVD) and 20 age- and sex-matched controls have been studied. Lymphocyte sensitization to insulin (LS) was revealed in 32 patients with stroke and in 5-with CVD.

[Characterization of peripheral erythron component in patients with localized thermal burns].

Cytospectrophotometry and electron microscopy of peripheral blood erythrocytes in patients with local surface thermal burns and healthy volunteers showed a notable decrease in the levels of sulfhydryl groups and lipoproteins, decreased number of biconcave discocytes, and increased number of transitional, prehemolytical, and degenerative forms of red blood cells. These changes were more pronounced during the early posttraumatic period and persisted for 2 months after burns were inflicted. Deep structural metabolic and morphological disorganization of the erythron peripheral component is a factor of risk of postburn complications.

[Intensity of lipid peroxidation processes and activity of antioxidant enzymes in erythrocytes during anemia in pregnancy].

The given report deals with investigation of the level of spontaneous lipid peroxidation (LPO) (as judged by the accumulation of MDA) and activity of antioxidative enzymes (GSH-peroxidase, GSH-reductase) in red blood cells of pregnant women (24-26 weeks) suffering from minor (blood Hb is 95 g/l) and medium (blood Hb is 85-90 g/l) anemias. We have found that as the anemia becomes deeper, the red blood cells of pregnant women demonstrate a linear increase in the level of spontaneous LPO, which rises by 54% during anemia of moderate severity (p < 0.02) as compared with control.

[Structural-functional changes in erythrocyte membranes in bovine lympholeukemia].

The condition of lipid peroxidation and activity of enzymes of protective glutathione-dependent anti-oxidation system of erythrocytes: glutathione peroxidase (GSH-P) and glutathione reductase (GSH-R) in cows with leukosis has been studied. The decrease of the level of MDA and GSH-R activity was accompanied by GSH-P activation depending on the stage disease. The considerable lowering of Ca2+ transport to erythrocytes was shown on hematological stage of leucosis.

[Protein and RNA synthesis in larvae of the yellow mealworm beetle (Tenebrio molitor) during cooling and cold acclimatization].

Functioning of protein-synthesis system freeze-avoiding larvae of Tenebrio molitor. (Tenebrinidae family) has been investigated at temperature lowering to 6-8 degrees. It has been shown that mealworms maintain the protein and RNA biosynthesis under cold acclimation (6-8 degrees C).
