Figure 2. Exogenous H2S decreases cell damage in the aged H9C2 cells. (A) Exogenous H2S decreased cell damage. The cells were cultured in glass-bottom dishes and observed using a general inverted microscope (magnification ×100). (B, C) Exogenous H2S inhibited the activity of LDH (C) and CK (B). The LDH and CK activities were detected in the cell culture fluid. Data are the means ± S.E.M. of 8 determinations. * p<0.05 vs. control group; # p<0.05 vs. H/R group; & p<0.05 vs. PC group; § p<0.05 vs. H/R + NaHS group; $ p<0.05 vs. PC + NaHS group.
