    Abstract:
    We studied the effect of a complex containing antioxidant vitamins C and E, provitamin A, and antioxidant element selenium on the contents of primary (lipid peroxides) and secondary products (malonic dialdehyde) of free radical lipid oxidation in low-density lipoproteins isolated from the plasma of patients with coronary heart disease and hypercholesterolemia by means of preparative ultracentrifugation. Activity of key antioxidant enzymes in the blood was measured during treatment with the antioxidant preparation. Combination treatment with antioxidant vitamins and antioxidant element selenium sharply decreased the contents of primary and secondary free radical oxidation products in circulating low-density lipoproteins and increased activity of antioxidant enzymes in erythrocytes. Activities of superoxide dismutase and selenium-containing glutathione peroxidase increased 1 and 2 months after the start of therapy, respectively.
