l-Cysteine attenuates subarachnoid hemorrhage (SAH)-induced apoptosis. (A) The detection of transferase dUTP nick end labeling (TUNEL)-positive cells in the prefrontal cortex was performed at 48 h after SAH. Scale bar = 50 μm. (B) Bar graphs showing the quantification of TUNEL-positive cells (n = 4). Scale bar = 50 μm. The values represent the means ± SD. ***p < 0.001 SAH vs Sham, ^###p < 0.001 SAH + l-Cys vs SAH, ⁺⁺p < 0.01 SAH + l-Cys + AOAA vs SAH + l-Cys. AOAA, amino-oxyacetic acid.
