| Abstract: | Antioxidation system in the brain and blood of rats with generalized bemegride-induced epileptic activity was studied. Antioxidation enzyme activity (superoxide dismutase, glutathione peroxidase and glutathione reductase) and alpha-tocopherol content were determined at an early convulsive stage, immediately after generalized seizures and 10-15 min after seizure. Antioxidation enzyme activity and alpha-tocopherol level in the brain homogenate and blood remained unchanged at any stages of investigation. It is suggested that the increased level of lipid peroxidation products in the brain and blood of rats upon the development of bemegride-induced epileptic activity is not related to the decrease in antioxidation system activity. The effect is mediated by the activation of the reaction initiating free radical brain lipid transformations. |
