INTERRELATION BETWEEN COMPENSATION OF CARBOHYDRATE METABOLISM AND SEVERITY OF MANIFESTATIONS OF OXIDATIVE STRESS IN TYPE II DIABETES MELLITUS

Glycosylation end-products formed during diabetes mellitus promoted atherogenic oxidative modification of low-density lipoproteins. We evaluated the effects of compensation of carbohydrate metabolism and therapy with antioxidant probucol on parameters of free radical oxidation in patients with type II diabetes mellitus. Compensation of carbohydrate metabolism reduced manifestations of oxidative stress, which was manifested in accelerated enzymatic utilization of reactive oxygen species and lipid peroxides and decreased content of free radical oxidation products in low-density lipoproteins. In patients with type II diabetes mellitus combination therapy with antioxidant probucol decreased the severity of oxidative stress and stabilized carbohydrate metabolism without increasing the dose of hypoglycemic preparations.
