[Study of activity of enzymes of antioxidant system of blood at HIV infection].

HIV infection is accompanied by activation of lipid peroxidation, oxidative modification of lipoprotein complexes, and a decrease in activity of antioxidant enzymes (superoxide dismutase (SOD), catalase and glutathione peroxidase (GP)) in blood serum. A significant increase of glutathione reductase observed under these conditions is considered as a function of the antioxidant defence. These changes were already seen at early (symptomless) stages of this disease, however, at manifested forms they were more pronounced.
