Effects of IPC and chelerythrine on levels of HO-1 (a), iNOS (b), and COX-2 (c) protein expression. HO-1, iNOS, and COX-2 protein expression in the liver was measured by immunoblots at 3 and 24 h after reperfusion. Blot shown is representative of three experiments with similar results. *,**Significant differences (P < 0.05, P < 0.01) versus the sham group; ⁺⁺significant differences (P < 0.01) versus the I/R group; ^#,##significant differences (P < 0.05, P < 0.01) versus the IPC + I/R group
