This study was carried out to evaluate cytotoxic effects of Houttuynia cordata THUNB extracts on A549 (lung cancer), MDA-MB231 (breast cancer), SNU-C4 (colon cancer) and B16 (mouse melanoma) cell lines. We have determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazoliumbromide (MTT) assay. The 150 $\mu$g/$m\ell$ concentration of methanol extract (63.81 ％) of Houttuynia cordata THUNB was shown significantly antitoxic activity on A549 cell lines. (omitted)

Houttuynia cordata Thunb (HCT) is a herbal plant growing in China, Japan and Korea. According to the records of the Chinese medicine, this plant has been used as folk medicine for analgesics, beriberi, edema, hepatitis, icterus, etc. 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. After 7 days from TCDD (1$\mu$g/kg) injection, HCT (200 mg/kg) was administered into rats intraperitoneally for 4 weeks. (omitted)

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.

YMV-K strains were purified from D. oppostita Thunb. tv. Dung-Gun-Ma showing mosaic symptom on their leaves. YMV-K strains were filamentous particles of 780nm in length and induced cytoplasmic disorder such as inclusion body formation. Nucleotide and amino acid sequences of 5'-UTR, Pl and CP of YMV-K strains shared 80.8, 64.7 and 98.3％ identity respectively to JYMV J1 in the mean value. Purification of YMV-K strains according to JYMV purification method(S. Fuji) was conducted to product antiserum. With antiserum against YMV-K strains, the Various diagnosis methods such as IC-RT-PCR, DIBA, RIPA and indirect-ELISA were used to detect YMV-K strains in Chinese yam plant.

To investigate an eliminatory effect of mixed extract of Hovenia dulcis Thunb, Gastrodia elata and Alnus japonica etc., on the ethanol-induced hangover, 12 hr-fasted male Sprague-Dawley rats weighing 220±20 g were given mixed extract (10 mL/kg, p.o.) and administered ethanol at a dose of 3 g/kg bw (25% in distilled water) orally 30 min postdosing. Blood was collected from caudal artery at 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hr and then the animals were sacrificed at 24 hr after the ethanol treatment. From 0 to 12 hr, the administration of mixed extract significantly decreased the area under the serum alcohol concentrations-vs.-time curves by 21 % compared with control group. In these experiments, liver function indices, such as alanine aminotransferase, aspartate aminotransferase and sorbitol dehydrogenase activities, showed unaltered results in all treated groups compared with the normal group. These results suggest that oral intake of the mixed extract may be effective on elimination of ethanol-induced hangover.
