HKL ameliorated neuronal damage after SAH in mice. a Representative images of Nissl staining and c quantitative analyses of Nissl positive neurons in each group 24 h after the operation are shown. Scale bar 50 μm. b Representative images of FJC staining and d Quantitative analyses of FJC-positive cells in each group 24 h after the operation are shown. Scale bar 50 μm. Values were represented as mean ± SD, n = 8 for each group. *P < 0.05 and **P < 0.01 vs. sham group, ^#P < 0.05 and ^##P < 0.01 vs. SAH group
