Abstract:
Objective To observe the change of nitric oxide(NO) and superoxide dismutase(SOD) in the epileptic rat brain cortex, and study the effect of the redox states of NO on epilepsy.Methods Using epileptic rat model induced by bemegride, the level of NO and the activity of SOD were measured in rat cerebral motor cortex during and only after seizures.Results The level of NO in rat cerebral motor cortex was significantly increased during and only after seizures than the normal controls. During seizures, SOD activity was decreased; but only after seizures, SOD activity was significantly increased.Conclusion The value of SOD activity than NO content had significantly difference in rat cerebral cortex between during and only after transient seizures. These results suggested that the different redox state of NO would play different role du ring the seizure.
