These studies were carried out to investigate the effects of Puerariae radix catechins(PRC) administration on the biochemical parameters of liver function in liver of carbon tetrachloride(CCl4)-treated rats. Thirty six healthy Sprague-Dawley rats weighing about 120g were used for this experiment and divided intot he following 3 groups : normal control group(NCON), $CCl_4$ control group(CCON), PRC treated group(PRC). Fifty percent $CCl_4$ in oil was administered(I.P.) by 2ml per kg body weight two times a week for 3 weeks. PRC treated groups were administered orally at the leaves of 1% per day in distilled water for 8 weeks. Lipid hydroperoxides were analyzed by using chemiluminescence-high performance liquid chromatography(CL-HPLC) method as a phosphatidylcholine hydroperoxide value(PCOOH) in liver tissues. $CCl_4$ treatment significantly(p<0.05) resulted in an increase in GPT & GOT activities and liver hydroperoxide values comparing with those of the untreated control, while administration of PRC to the $CCl_4-treated$ rats significantly(p<0.001) decreased GPT & GOT activities and liver hydroperoxide value. Their ultrastructual changes of hepatocellular organelles were shown to clarify the morphologic nature of protective effects of PRC on hepatocytic injuries. $CCl_4$ treatment observed to change the ultrastructual nature of outer membrane of hepatocytes. However, the hepatic changes on PRC treatment to $CCl_4$ group was not found. PRC administration may inhibit the formatiion of liver lipid hydroperoxides in vivo and were very effective in recovering the liver function in $CCl_4-treated$ rats.
