Heme oxygenase-1 protects rat liver against warm ischemia/reperfusion injury via TLR2/TLR4-triggered signaling pathways

Figure 1 Serum concentrations of liver enzymes and myeloperoxidase activity. The hepatocellular function, as evidenced by serum aspartate aminotransferase (ALT) (A), aspartate aminotransferase (AST) (B) and lactate dehydrogenase (LDH) (C) levels were decreased in cobalt protoporphyrin (CoPP) treatment group, compared with zinc protoporphyrin (ZnPP) treatment. The myeloperoxidase (MPO) activity (D) was decreased in livers subjected to CoPP, compared with ZnPP. Data are shown as mean ± SE, (n = 4 per group).
