환경호르몬으로 독성이 강하기로 유명한 TCDD는 간을 포함한 각 조직에 손상을 주고, 내분비의 붕괴를 야기 시킨다. 본 연구는 TCDD로 처리한 rat의 간과 혈장을 사용하여, 어성초의 생화학적 효과를 연구하였다. TCDD를 투여한 지 일주일 후부터 어성초 200 mg/kg을 4주간 격일로 투여하고 TCON군과 NO군은 saline을 투여하였다. 혈청에서 total cholesterol, HDL-cholesterol, LDL-cholesterol, total lipid, triglyceride(TG)를 간조직중에서 MDA를 측정함으로써 과산화지질 활성도와 콜레스테롤의 양을 조사하였다. TCDD로 처치한 rat에 어성초 추출물을 투여했을 때, 과산화지질 및 콜레스테롤이 유의적인 수준으로 억제되었다.
TCDD, one of the notorious toxic environmental pollutants, damages various organs including liver and is regarded as an endocrine disrupter. To investigate the effects of Houttuynia cordata Thunb (HCT) on the biochemical parameters of function, liver and serum of TCDD-treated rats were used. Seven days after the injection of TCDD (1 $mu extrm{g}$/kg), HCT (200 mg/kg) was administered to rats on every other day for four weeks. The lipidperoxide activity was examined by measuring the level of total cholesterol, HDL-cholesterol, LDL-cholesterol, total lipid and triglyceride (TG) in serum, and malondialdehyde (MDA) in liver tissue of rats. Result showed that lipidperoxidation was inhibited In the significant level when 2,3,7,8-TCDD-damaged rats were treated with HCT
