Representative Western blots of caspase-12 activity in rabbit cortex in the experimental groups. (A) Representative autoradiogram of the caspase-12 expression by Western blot. (B) Quantitative analysis of caspase-12 expression detected by Western blot. As is shown, caspase-12 was significantly increased in the SAH and SAH + saline groups compared with that in the control group. However, caspase-12 expression decreased obviously in the hydrogen-rich saline group compared with SAH or SAH + saline groups. Bars represent the mean ± SE. #P < 0.05 compared with control group; *P < 0.05 compared with SAH or SAH + saline group.
