[Antioxidative status changes in golden syrian hamsters with experimental metabolic syndrome].
Some indices of the antioxidant status (content of the alpha-tocopherol, reduced glutathione and ascorbic acid, activity of the glutathione reductase and aryl-esterase) and lipid peroxidation processes in the liver, blood serum, and some blood serum lipoprotein fractions of the Golden Syrian hamsters of different sex and age status under high-caloric diet were investigated. It has been shown that the hypercaloric diet leads to a decreaseng of reduced glutathione content and increase of the level of lipid peroxidation products in the liver of experimental animals. The ascorbic acids content in male liver is decreased and in female liver is increased. In the blood serum under hypercaloric nutrition the accumulation of lipid peroxidation products and alpha-tocopherol content a decrease in ApoB-lipoproteins and HDL is observed. Simultaneously the ascorbic acid content is increased in the blood serum of all experimental animals. Activation of free-radical oxidation both in the liver, and blood serum is more significant in males compared with females. The data obtained allow to suppose that atherosclerotic complications of metabolic syndrome development may be connected to the lipoprotein oxidant status infringement.
