ABSTRACT
Background The chemoprevention of chemically-induced hepatotoxicity is a crucial means of minimizing susceptibility to hepatic carcinogenesis and plants remain a rich source of anti-hepatotoxicants with antioxidant properties. Objective The protective role of defatted-methanol (MECF) and ethyl acetate fractions (EF), obtained from Leaves of Cnestis ferruginea in rats induced with carbon tetrachloride (CCl4) toxicity was investigated. Materials and Methods Adult male Wistar rats were orally administered MECF or EF (125 – 500 mg/kg bwt/5mL) or silymarin (25 mg/kg bwt/5 mL) separately for three days before intervention with an intraperitoneal dose of CCl4 Biomarkers of liver and kidney toxicity as well as Ca2+ regulation were evaluated. Results Pre-treatment with MECF and EF significantly (P < 0.05) decreased the activities of serum alanine and aspartate aminotransferases, levels of urea, creatinine and cholesterol. A significantly (P < 0.05) enhanced Ca2+-ATPase activity and lowered levels of membrane cholesterol: Phospholipid ratio were observed in liver microsomes of pre-treated as compared to CCl4-only treated rats. Rat liver superoxide dismutase activity was enhanced by 125 mg/kg and 250 mg/kg of EF and MECF, while decreases were observed at 500 mg/kg. MECF and EF, like silymarin, attenuated CCl4-induced hepatotoxicity, microsomal membrane Ca2+-ATPase inactivation and renal dysfunction. Phytochemistry of MECF revealed the presence of anthraquinones, cardiac and flavone glycosides, tannins and trihydroxyl phenol. Conclusion These findings suggest that the mechanism of hepatoprotection elicited by MECF and EF, involve its antioxidative properties and regulation of Ca2+ homeostasis.
