Houttuynia Cordata thunb has been used as folk medicine for analgesics, beriberi, edema, hepatitis and icterus etc. We investigated, the effects of Houttuynia Cordata thunb administration on protective in liver of 2,3,7,8- tetrachlorodibenzo-p-dioxin(TCDD) treated rats. Seven days after the injection of TCDD(1㎍/kg), Houttuynia Cordata thunb (200mg/kg) was administered into rats intraperitoneally for four weeks. We examined the antioxidative enzymatic activity by measuring the level of GOT, GPT in serum and MDA, GSH, GSSG, GPx, SOD and Catalase in liver tissue of rats. GOT activity of Houttuynia Cordata thunb and TCDD administered group(HTT) showed 49.00% of inhibitive effect compared to TCDD-treated abnormal group(TTA). GPT level of HTT group was decreased to the level of Non TCDD-treated group(NTT). MDA content in the TTA group was 1.27 times increased compared to NTT group. HTT group was inhibited by 69.53% compared to TTA group. GSH contents in HTT group was 1.91 times increased compared to TTA group. GSSG contents in HTT group was 46.72% decreased compared to TTA group. SOD and Catalase in TTA group were lower than in NTT group, but SOD and Catalase in HTT group were increased by 82% and 55.45% respectively compared to TTA group.
