Figure 1 Representative histologic sections of a chronic bile duct ligation (CBDL) and control rat liver. (A) The CBDL rat demonstrates bile ductular proliferation without significant portal fibrosis or inflammation when compared with the liver from a (B) control animal (Trichrome stain, ×100).

Figure 6 Levels of free isoprostanes and TBARS in the (A and B) systemic circulation and in (C and D) renal vein plasma at 21days. *P < 0.05 vs. control; †P < 0.05 vs. CBDL. CBDL is chronic bile duct ligation; TBARS is thiobarbituric acid reactive substances. Kidney International , DOI: ( /j x) Copyright © 2003 International Society of Nephrology Terms and Conditions
