Effects of IPC and chelerythrine on serum aminotransferase activities (a) and histological features of liver sections with H&E staining (b) at 3 and 24 h after reperfusion. Typical images were chosen from each experimental group (×200, scale bar 200 μm) and arrows indicate the necrotic area. Results are presented as mean ± SEM of sham, 3 h (n = 8); I/R, 3 h (n = 9); IPC + I/R, 3 h (n = 10); CHE + IPC + I/R, 3 h (n = 10); sham, 24 h (n = 8); I/R, 24 h (n = 9); IPC + I/R, 24 h (n = 10); CHE + IPC + I/R, 24 h (n = 10). **Significant differences (P < 0.01) versus the sham group; ⁺significant differences (P < 0.05) versus the I/R group. ^#significant differences (P < 0.05) versus the IPC + I/R group
