Abstract:

The aim of this study is to examine the therapeutic effects of Olea europaea L. leaf extract on carbon tetrachloride (CCl)-induced liver damage in rats. In the experiments, 3- to 4-month-old 28 male Sprague-Dawley rats were divided into four groups: control, O. europaea leaf extract, CCl, and curative. The CCland curative groups received CCl(0.2 mL/kg) intraperitoneally for 10 days to form hepatic injury. O. europaea (80 mg/kg) leaf extract was given orally to the curative group dissolved in distilled water the following 14 days. Hepatic and antioxidant enzyme levels, p53, caspase 3, lipid peroxidation marker malondialdehyde (MDA), andalso DNA fragmentation levels were determined to establish oxidative stress in hepatic cell damage and its consequences. After formation of liver damage, oral administration of the O. europaea significantly reduced CCl-induced elevations of serum alkaline phosphatase, aspartate aminotransferase and alanine aminotransferase levels (P < .001), MDA levels of both blood (P < .001) and liver tissues (P < .001), DNA fragmentation (P < .001), p53 (P < .001), and caspase 3 (P < .001) levels of liver tissues. Also this administration in curative group significantly increased CCl-induced reductions of superoxide dismutase (SOD) (P < .001) and catalase (CAT) (P < .001) activity of blood samples and decreased SOD (P < .001) and CAT (P < .05) activity observed in liver tissue curative groups compared with CClcurative group. In CClgroup, liver tissue samples exhibited remarkable damage because of CCland reduction of these damages were observed in the curative group. Our results showed that O. europaea leaf extract was effective in reducing hepatic damage caused by CClby reducing lipid peroxidation, regulating antioxidant enzymes, and minimizing DNA damage.
