SELENIUM SATURATION OF HEMOGLOBIN AS ANTIOXIDATIVE FACTOR AT HIGH TENSION ELECTRIC FIELDS ACTION

High tension electrical fields represent a physical environmental factor influencing on oxidativedestructive processes rate in human organism. Resistance to this electrical field depends mainly on multicomponent system of natural antioxidants. Among them trace element selenium and enzyme glutathione peroxides are of great importance. However the mechanism of antioxidative action of selenium has not been investigated completely. Creating selenium-deficit conditions is essential for study of the action mechanism. Hence, both the erythrocytes of pregnant women and the erythrocytes at glucose-6-phosphatedehydrogenase enzyme deficiency are appropriate natural models. The results of investigations have shown that the erythrocytes of pregnant women (initial stage of pregnancy) proved to be more resistant to electrical field effect than the erythrocytes with glucose-6-phosphatedehydrogenase pathology. Due to the intensive consumption of Se at late stages of pregnancy, erythrocytes of pregnant women are more labile to oxidation than the glucose-6- phosphatedehydrogenase deficiency erythrocytes, thus that glutathione peroxides activity of erythrocytes of pregnant women remains close to norm.
