Effects of Z. zerumbet extract on serum superoxide dismutase (a), brain superoxide dismutase (b), serum catalase (c), brain catalase (d), serum glutathione peroxidase (e), brain glutathione peroxidase (f) activities and brain glutathione level (g). Values are expressed as mean ± SEM. “a” significant at F(5,18) = 16.978, p < 0.5 compared to normal group; “b” significant at p < 0.05 compared to ethanol group. (N = 6). (EtOH: ethanol; 200 + EtOH: 200 mg/kg extract + ethanol; 400 + EtOH: 400 mg/kg extract + ethanol)
