Figure 6From: Extended normobaric hyperoxia therapy yields greater neuroprotection for focal transient ischemia-reperfusion in ratsEffect of NBO on the activity of caspase-3 in cortex penumbral at 22.5 h reperfusion after 90-min ischemia. Data is expressed as mean ± SD, n = 5 in each group. *P < 0.05 and **P < 0.01vs. operation-sham; # P < 0.05 and ## P < 0.01 vs. normoxic group.Back to article page
