Representative Western blots of caspase-3 activity in rabbit cortex in the experimental groups. (A) The activity of caspase-3 detected by Western blot in the experimental groups. (B) Quantitative analysis of caspase-3 expression detected by Western blot. As is shown, the level of caspase-3 increased substantially in the SAH and SAH + saline groups compared with that in the control group. In contrast, caspase-3 expression decreased significantly in the SAH + hydrogen-rich saline group compared with that in the SAH or SAH + saline group. Bars represent the mean ± SE. #P < 0.05 compared with control group; *P < 0.05 compared with SAH or SAH + saline group.
