摘      要：BACKGROUND： Oxidative stress plays an important role in the pathophysiology of epilepsy. Glutathione, known as one of the compounds of antioxidant defense, has been shown to inhibit convulsions. Nitric oxide has a proconvulsant effect on a pentylenetetrazole-induced animal model. OBJECTIVE： To evaluate the effects of glutathione administration on nitric oxide levels in brain regions of convulsive and kindling pentylenetetrazole-induced seizure models. DESIGN, TIME, AND SETTING： A randomized, controlled, animal experiment. The study was performed at the Department of Physiology, Gaziantep University and Department of Chemistry-Biochemistry,Kahramamaras Sutcu Imam University in 2006. MATERIALS： Pentylenetetrazole and glutathione were purchased from Sigma, USA. METHODS： A total of 80 mice were assigned to 8 groups （n = 10）： normal control, saline control （1 mL normal saline）, convulsive pentylenetetrazole （single intraperitoneal administration of pentylenetetrazole, 60 mg/kg）, convulsive pentylenetrazole plus glutathione （single administration of 60 mg/kg pentylenetetrazole and 200 mg/kg glutathione）, five-dose glutathione （intraperitoneal injection of 200 mg/kg glutathione respectively at 1, 3, 5, 7, and 10 days）, single-dose glutathione （single administration of 200 mg/kg glutathione）, pentylenetetrazole kindling （intraperitoneal administration of pentylenetetrazole of 40 mg/kg at 1,3, 5, 7, and 10 days）, and pentylenetetrazole kindling plus glutathione group （intraperitoneal injection of 40 mg/kg pentylenetetrazole and 200 mg/kg glutathione respectively at 1, 3, 5, 7, and 10 days）. MAIN OUTCOME MEASURES： All mice were sacrificed 1 hour after the last administration. Brain nitric oxide levels were determined by spectrophotometry. RESULTS： There were no significant differences in nitric oxide levels between the normal control, saline control, five-dose glutathione, and single-dose glutathione groups （P 〉 0.05）. Nitric oxide levels in the cerebral hemisphere and cerebe
