MLB suppresses hepatic fibrosis in TAA-treated rats. The extent of hepatic fibrosis was assessed by Masson's trichrome staining (A, B, C, and D, original magnification × 40); (A) TAA 8-week, (B) TAA 8-week + MLB, (C) TAA 12-week, (D) TAA 12-week + MLB. (E) Masson's trichrome-stained area was quantified using a computerized imaging analysis system. (F) Hepatic hydroxyproline content was colorimetrically quantified from liver samples. *P < 0.05 compared with TAA 8-week, **P < 0.01 compared with TAA 8-week, †P < 0.01 compared with TAA 12-week.
