l-Cysteine ameliorated subarachnoid hemorrhage (SAH)-induced brain injury. (A) Neurological scores were recorded at 48 h after SAH (n = 6). (B) Brain water content of the cerebral cortex was measured at 48 h after SAH (n = 6). (C) H&E staining was performed on brain tissues at 48 h after SAH. Pathological changes included focal edema in the prefrontal cortex (black arrows indicated) (n = 4). Scale bar = 100 μm. The values represent the mean ± SD. **p < 0.01, ***p < 0.001 SAH vs Sham, ^#p < 0.05, ^##p < 0.01 SAH + l-Cys vs SAH, ⁺p < 0.05 SAH + l-Cys + AOAA vs SAH + l-Cys. AOAA, amino-oxyacetic acid.
