Effects of the NaHS on mortality, neurological behavior impairment and brain edema after SAH. (A) Mortality was recorded at 48 h after SAH. (B) Neurological scores were recorded at 48 h after SAH, n = 15. (C) Brain water content of cerebral cortex was measured at 48 h after SAH, n = 6. Values represent the mean ± SD, **p < 0.01, ***p < 0.001 SAH vs. Sham; #p < 0.05, ##p < 0.01 SAH + NaHS vs. SAH.
