Chlorella vulgaris extract ameliorates carbon tetrachloride-induced acute hepatic injury in mice
چکیده انگلیسی

The possible protective effects of Chlorella vulgaris extract (CVE) on carbon tetrachloride (CCl4)-induced acute hepatic injury in mice and the mechanism underlying these effects was investigated. CCl4 administration caused a marked increase in the levels of serum aminotransferases, lipid peroxidation and cytochrome P450-2E1 (CYP450) expression. Also, decreased glutathione (GSH) content and activities of cellular antioxidant defense enzymes such as superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase and glutathione-S-transferase (GST) were found after CCl4 exposure. All of these phenotypes were markedly reversed by preadministration of the mice with CVE. In addition, CVE exhibited antioxidant effects on FeCl2–ascorbate induced lipid peroxidation in mouse liver homogenates, and on superoxide radical scavenging activity. Taken together, these results suggest that CVE produced a protective action on CCl4-induced acute hepatic injury in mice, presumably through blocking CYP-mediated CCl4 bioactivation, inducing the GSH levels, antioxidant enzyme activities and free radical scavenging effect. Therefore, CVE may be an effective hepatoprotective agent and viable candidate for treating hepatic disorders and other oxidative stress-related diseases.
