NaHS treatment suppresses apoptosis.

(A) Representative photomicrographs of TUNEL staining results in the ischemic core and peri-infarct regions (magnification 200×). Red arrow indicates apoptotic cells; blue arrow indicates viable cells. (B, C) Quantification of the effect of NaHS treatment on the apoptosis rate in the ischemic (B) core and (C) peri-infarct regions. Data are presented as mean ± standard deviation (n = 8 rats in each group). * P < 0.001 vs. the control group, # P < 0.001 vs. the NaHS 30 group.
