Fig. 7From: DL-3-n-butylphthalide improved physical and learning and memory performance of rodents exposed to acute and chronic hypobaric hypoxiaEffects of NBP on the oxidative stress of rats under conditions of acute and chronic hypoxia after the shuttle-box experiment. Levels of MDA, H2O2, SOD, and GSH-Px in the serum of acute (a) and chronic (b) hypoxia rats were detected. *P < 0.05 compared with control group; ∆P < 0.05 compared with 120 mg/kg groupBack to article page
