Abstract

This study was done to investigate the protective effects of Diospyrus kaki Folium on carbon tetrachloride intoxicated rats. Male Sprague-Dawley rats (200~230g) was used. Experimental groups were divided into normal group and $CCl_{4}$-treated group and then $CCl_{4}$-treated groups were divided into 7 groups: only $CCl_{4}$-treated group, methanol extract pretreated group, butanol fraction pretreated group and $H_{2}O$ fraction pretreated group, $CCl_{4}$ treated groups were injected with $CCl_{4}$ 0.6 mg/kg (ip). The activities of ananine aminotransferasein hexane, chloroform and $H_{2}O$ fraction pretreated groups were significantly decreased (p<0.05) compared to the only $CCl_{4}$-treated group and also activity of aspartate aminotransferase and hepatic malondialdehyde content in $H_{2}O$ fraction pretreated group were significantly decreased (p<0.05) compared to the only $CCl_{4}$-treated group. The activity of alkaline phosphatase in chloroform and $H_{2}O$ fraction pretreated groups were decreased compared to the only $CCl_{4}$-treated group but the difference was not statistically significant. The activity of ${\gamma}$-glutamyltranspeptidase in hexane, chloroform and ethylacetate fraction pretreated groups were significantly decreased (p<0.05) compared to the only $CCl_{4}$-treated group. The contents of cholesterol and triglyceride were not influenced in any fraction pretreated groups, but HDL-cholesterol content in hexane and chloroform fraction pretreated groups were significantly increased (p<0.05) compared to the only $CCl_{4}$-treated group. Therefore, these results demonstrate a possible hepatoprotective role of $H_{2}O$ fraction of Diospyrus kaki Folium methanol extract in carbon tetrachloride intoxicated rats.
