Abstract: Atherosclerotic lesion of the aorta and lipid peroxidation (LPO) in blood and in lipoproteins produced in hepatocytes were studied in rabbits with experimental atherosclerosis maintained on a diet enriched in polyunsaturated fatty acids containing in corn oil (2 ml/kg daily during 30 days) and antioxidants alpha-tocopherol and carnosine (2.5 mg/kg and 50 mg/kg, respectively, daily during 30 days). This diet exhibited a hypocholesterolemic effect accompanied by approximately a 10-fold decrease of the impaired aortic area, as well as lowered content of 2-thiobarbituric acid-positive LPO products occurring in blood and, especially, in apoB lipoproteins. The antioxidant-containing diet decreased distinctly the content of LPO products both in the liver tissue homogenate and lipoprotein fraction (d < 1.065 g/cm3) produced by hepatocytes during 30-min perfusion of liver tissue. The findings suggest that the diet enriched in polyunsaturated fatty acids and antioxidants contributed to a decrease of LPO products content in the blood serum and apoB lipoproteins as well as to the inhibition of lipoprotein oxidation during their synthesis in liver cells; the diet may be recommended for the prophylaxis and treatment of atherosclerosis.
