Biochemical quantification of hepatic hydroxyproline (HYP) content and αSMA in models of chronic liver injury in rats. (A) Hepatic HYP content in control, CCl4/Vehicle‐ and CCl4/Ex_31‐treated rats. (B) Hepatic αSMA content in control, CCl4/Vehicle‐ and CCl4/Ex_31‐treated rats. (C) Hepatic HYP content in CSAA or CDAA diet‐fed rats treated with Vehicle or Ex_31. (D) Hepatic αSMA content in CSAA or CDAA diet‐fed rats treated with Vehicle or Ex_31. Values are normalized versus liver protein content. Data represent mean ± SEM, n = 10 (control), n = 13 (CCl4‐treated) and n = 12 (CSAA‐ and CDAA‐fed), *P < 0.05.
