Inhibiting heme oxygenase-1 attenuates rat liver fibrosis by removing iron accumulation

Figure 2 Van Gieson’s staining of collagen I for liver sections and liver hydroxyproline content. A-F: Collagen type I was deposited in the bile duct ligation (BDL) group, cobalt protoporphyrin (CoPP) group and Fe group (B, C and E) and was rarely found in the Sham group, zinc protoporphyrin (ZnPP) group and deferoxamine (DFX) group (A, D and F); G: The area of collagen type I; H: Hydroxyproline content of liver tissue (magnification, × 100). Values are expressed as mean ± SE (n = 6). ^bP < 0.01 vs Sham group; ^cP < 0.05, ^dP < 0.01 vs BDL group; ^eP < 0.05 vs ZnPP group.
