Abstract: Background and Objective: Carbon tetrachloride (CCl4), a carcinogenic compound commonly used in household cleaning agents and spot removers can cause free radical-mediated liver damage. Recent research shows polyphenols in pomegranate (Punica granatum L.), rich in exogenous antioxidants, may protect the liver from hepatotoxic damage. This study aimed to investigate the effect of pomegranate juice on CCl4-induced liver damage in a rat model. Materials and Methods: A total of 25 rats, aged 8 weeks and weighing an average of 200 g were used. They were divided into 5 groups as follows: (1) Normal, (2) Hepatotoxic rats and (3), Hepatotoxic rats with pomegranate juice 0.4 mL/200 g body weight (BW) (4) Hepatotoxic rats with pomegranate juice 0.8 mL/200 g BW and (5) Hepatotoxic rats with pomegranate juice 1.2 mL/200 g BW, respectively. Hepatotoxicity was done by intraperitoneal injection of 0.5 mL–1 CCl4 kg–1 BW for 5 days. Before and after 2 weeks administration of treatment, blood samples were collected for assessment of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (γ-GT) and malondialdehyde (MDA). At the end of the study, the animals were euthanized and the livers were used for histopathological assessment. Data were analyzed by paired t-test and one-way ANOVA followed by the Games-Howell test. Results: Supplementation with three different doses of pomegranate juices in CCl4-induced rats significantly reduced the serum levels of ALT, AST, ALP, γ-GT and MDA (p<0.05) and pomegranate juice as much as 0.8 and 1.2 mL/200 g BW reduced liver damage in CCl4-induced rats. Conclusion: According to findings of this study supplementation with pomegranate juice can improve liver damage induced by CCl4 in rats.
