Abstract
The aim of this study was to investigate the effect of combined therapy of vitamin E and selenomethionine to pro/ antioxidant status in experimental hypercholesterolemia. Thirty male rabbits were included in the study and randomized into five groups consisting of the control group (standard diet) and four experimental groups staying on a diet rich in cholesterol (0.5 g/100 g diet): cholesterol group and groups supplemented cholesterol with selenomethionine (12.5 μg/kg body mass/24 h) or vitamin E (10 mg of Dl-α-tocopherol/kg body mass/24 h) or combination of the above antioxidants for 3 mo. The activity of superoxide dismutase (SOD), glutathione peroxidase (GPX), and catalase (CAT) as well as the concentration of malondialdehyde (MDA) was estimated in the blood during every month of experiment. Increased activity of SOD and GPX with a decreased concentration of MDA in comparison to the cholesterol diet was found mainly in the combination of study antioxidants. The supplementation of the cholesterol diet with combined doses of vitamin E and selenomethionine appears to prevent the lesions induced by experimental hypercholesterolemia much more efficiently than single doses of the above.
