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 $\mu\textrm{g}$/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.

TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin), 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. After 7 days from TCDD (1 $\mu\textrm{g}$/kg) injection, HCT (200 mg/kg) was administered into rats intraperitoneally for 4 weeks. The lipidperoxide content 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.

Motherwort (Leonurus sibiricus L), a hemp nettle (Labiatae) plant, grows about 1.5${\~}$2 m high spontaneously to wildness in Korea, China, Japan, and other Asian place. Its medical applications includes women's uterine disease, urination, bloody stool, bloody urine, and hemorrhoids. It's also effective for high blood pressure, heart stimulation, and anti-cancer activity. We first prepared chlroform and methanol extracts of motherwort and then they were fractionated using water, $30\%$ methanol, $60\%$ methanol, and $100\%$ methanol, respectively. Each fractionates is assayed for free radical scavenging activities against DPPH and anti-oxidant activity by TBARS assay measuring lipid peroxidation using LDL. The $30\%$ and $60\%$ methanol fractionates of methanol extracts showed strong anti-oxidant activity compared to vitamin C. They also had more Potent SOD activity using pyrogallol at 250 ppm than that of vitamin C. These results suggest that anti-oxidant activities of motherwort may be applicable to development of natural anti-oxidant cosmetics. Possibility of nature anti-oxidation ability cosmetics is seen possibility low official.
