The (137)Cs accumulation by forest-derived products in the Gomel region.

This paper reports basic features of the (137)Cs uptake by forest-derived products in the Gomel region. Even with the soil contamination density of 37 kBq m(-2) the radionuclide contents in 20-30% of mushrooms and berries were found to be higher than the admissible levels. The (137)Cs contamination density of soil, site type and meteorological parameters were observed as the major factors which govern the radiocaesium uptake by mushrooms and berries. The (137)Cs contents in forest-derived products were found to increase directly with the soil contamination density. Bilberries (Vaccinium myrtillus) growing on different site types differed significantly in the (137)Cs content. It was also determined that statistically significant differences in the (137)Cs radioactivity of forest foods growing on different natural sites were governed by the factor designated in the current study by "territorial". The differences are to be accounted for both by forms of the Chernobyl fallout and by the natural and climatic conditions determining variations in the availability of radionuclides in the soil. In dry years the (137)Cs concentrations in some mushroom species were higher than in normal years.

[Effect of the biopreparation "Polyene" on parameters of blood fatty acid composition in volleyball athletes]. / Vliianie biopreparata "polien" na pokazateli zhirnokislotnogo sostava krovi u sportsmenov-voleibolistov.

[Changes in the fatty acid composition of serum albumin in patients with lung and breast neoplasms]. / Izmenenie zhirnokislotnogo sostava syvorotochnogo al'bumina u bol'nykh s onkopatologiei legkikh i molochnoi zhelezy.

Serum albumin fatty acid composition of patients with lung and mammary gland oncopathology was investigated by chromatography method. Differences in the contents of families 6 and 3 fatty acids were showed that depend on disease stage and tumour localization. omega 6/ omega 3 ratio increase in the early stages of tumour process was established for both pathologies. These findings can be used in a diagnostic test to discover early stages of tumour.

[Lipid composition of blood plasma and erythrocyte membrane of volleyball players under intensive physical load]. / Lipidnyi sostav plazmy krovi i membran éritrotsitov u voleibolistov v usloviiakh intensivnoi fizicheskoi nagruzki.

As the result of prolonged training activity highly skilled volleyball players have marked deficiency of fatty acids of w3 family both in the blood plasma as erythrocyte membranes. These acids may be used in the lipid peroxidation processes, that is proved by the facts of POL products content and their drawing into oxidation reaction, which is certified by high level of ATP in erythrocytes. Reduction of quantity of polyunsaturated fatty acids of w3 family may be regarded as results of their insufficient arrival with food.

[The indices of intraerythrocyte metabolism and hemoglobin oxygen affinity in volleyball players under intensive physical loads]. / Pokazateli vnutriéritrotsitarnogo metabolizma i srodstvo gemoglobina k kislorodu u sportsmenov-voleibolistov pri intensivnykh fizicheskikh nagruzakh.

The authors' investigations led them to the conclusion that skilled volleyball players' erythrocytes undergo adaptive metabolic rearrangement. There was also low hemoglobin affinity to oxygen. A single training load provoked the effect of metabolic enhancement as a result of increased red cell concentration of glucose, glycosylated hemoglobin and high activity of hexokinase.

[Features of transport function and structure of serum albumin in cancer]. / Kharakteristika transportnoi funktsii i struktury syvorotochnogo al'bumina u onkologicheskikh bol'nykh.

Levels of lipid ligands in serum albumin from cancer patients were assayed versus tumor localization. Abnormal non-specific increase in albumin-bound lipids as well as in peroxidation products was found. Gas-liquid chromatography of different polynonsaturated fatty acids pointed to the enhancement of their metabolism via the omega 3 pathway. The despiralization-type changes in secondary structure of albumin identified by procedures of spectral analysis and the decline in reserve functional activity of protein in tumor patients were matched by a rise in levels of serum albumin-transported ligands. It is suggested that such increase in the ligand-binding ability of albumin provides a major adaptive factor involved in oncopatology.

[A structural-functional assessment of serum albumin in cancerous diseases]. / Strukturno-funktsional'naia otsenka syvorotochnogo al'bumina pri onkologicheskikh zabolevaniiakh.

HSA structure was studied in healthy subjects and cancer patients using infrared spectroscopy. No significant differences were observed although the intensity of valent C-H fluctuation lines in alkyl groups of HSA was slightly increased in cancer patients. Gas-liquid chromatography established changes in the profile of polyunsaturated fatty acids binding to HSA in cancer patients. The data obtained suggest inhibition of omega-6 pathway of fatty acid metabolism and activation of omega-3 pathway. Marked binding of POL products to serum albumin was found nonspecific and was considered evidence of protective function of that protein.
