Fig. 4From: DL-3-n-butylphthalide improved physical and learning and memory performance of rodents exposed to acute and chronic hypobaric hypoxiaEffects of NBP on the time and distance to motor exhaustion of mice and rats under conditions of acute and chronic hypoxia. Time (a) and distance (b) to exhaustion of mice in the forced exercise wheel-track treadmill experiment at 5800 m for 3 days. Time to exhaustion of rats in the treadmill running experiment at 5800 m for 3 days (c) and 20 days (d). *P < 0.05 compared with control group; #P < 0.05 compared with 60 mg/kg groupBack to article page
