(A) The apoptosis of rat brain tissue after TUNEL staining was observed under 200-fold magnification (×200, n = 8). Effect of administration groups on the brain cells’ apoptosis rate (B) and caspase-3/9 (C,D) level of MCAO rat models (n = 8). ## p < 0.01, ### p < 0.001, compared with sham group; * p < 0.05, ** p < 0.01, *** p < 0.001; compared with MCAO group; ns: no significant difference, ▲ p < 0.05, ▲▲ p < 0.01, compared with NLXT group.
