The kiwi (Actinidia deliciosa) is well known to contain anti-oxidants. In this study, we investigated the anti-oxidant effects of kiwi extract on carbon tetrachloride ($CCl_4$) induced liver injury in BALB/c mice. The radical scavenging effect of 80% methanol extract of Halla-Gold kiwi was observed. For the animal study, mice were randomly divided into four groups: normal group, $CCl_4$-induced model group, kiwi extract administered group, and silymarin treated group. The kiwi extract was provided daily for 10 days. At the 24 h after last administration, $CCl_4$ was injected. The kiwi extract showed strong inhibitory effect of DPPH radicals and superoxide scavenging. In animal study, administration of $CCl_4$ resulted in significantly elevated plasma levels of ALT and AST but they decreased in kiwi-extract pretreated group. Anti-oxidant enzymes such as GSH-px and GSH-rd were restored in the kiwi extract treatment group. Histopathological degeneration was also prevented in the kiwi extract treated group compared with of the control group, which exhibited $CCl_4$-induced hepatotoxicity. On the basis of the obtained results, it can be concluded that kiwi extract showed protective effects, not only as anti-oxidant effects, but also in the protection of hepatotoxicity in $CCl_4$-intoxicated mice.
