Abstract
This study was conducted to investigate the protective effects of water extract from Crassostrea gigas (CGW) against ethanol-induced hepatic toxicity in rats. Seventy-two male Wistar rats (6-week-old) were divided into six groups of 12 animals each: control group (1 mL saline/d), ethanol-treated group, positive control group (ethanol+Hovenia dulcis Thunb extract), CGWL group (ethanol+low dosage of CGW), CGWM group (ethanol+medium dosage of CGW), and CGWH group (ethanol+high dosage of CGW). All groups except the control group received ethanol (40% ethanol 5 g/kg) orally. CGW administration with ethanol resulted in prevention of ethanol-induced hepatotoxicity by increasing levels of serum alanine aminotransferase and ${\gamma}-glutamyltransferase$. CGW supplementation significantly reduced formation of malonaldehyde and inhibited reduction of hepatic glutathione and peroxidase levels, as compared with the ethanol-administration group. Further, CGW suppressed expression of CYP2E1, which was elevated by ethanol administration. Consequently, our results indicate that Crassostrea gigas may exert hepatoprotective effects against alcohol-induced hepatocyte injury by intensifying the anti-oxidative defense system.
