  • This study was conducted to investigate the antitoxic effects of Houttuynia cordata THUNB with chloroform and ethyl acetate fractions. The results were as follows: 1. Detoxication effects of chloroform and ethyl acetate fractions of Houttuynia cordata THUNB were increased in proportion to the dosages. Detoxication effects of ethyl acetate fraction of Houttuynia cordata THUNB were higher than chloroform fraction of Houttuynia cordata THUNB's results and detoxication effects in the kidneys were higher than results for the liver. 2. Metallothionein concentrations in the liver were higher than concentrations in the kidneys, and ethyl acetate fraction of Houttuynia cordata THUNB was higher than chloroform fraction of Houttuynia cordata THUNB in induction of metallothionein. 3. After the administration of chloroform and ethyl acetate fractions of Houttuynia cordata THUNB, body weights increased in proportion to chloroform and ethyl acetate fraction s dosage of Houttuynia cordata THUNB but changes of body weight dminished after 3 weeks. From the above results, this study suggests that chloroform and ethyl acetate fraction of Houttuynia cordata THUNB increased metallothionein induction to cadmium intoxication in rat s kidney and liver and decreased the toxicity of cadmium in rats.

  • Houttuynia Cordata Thunb, well known as "E-Sung Cho" in Korea, has been used for the treatment of herpes simplex, chronic sinusitis and nasal polyps. Recently, some studies reported the antileukemic activity, anticancer activity, adjuvanticity, and antioxidant action of Houttuynia Cordata Thunb. In the present study, the anti-obesity activity of Houttuynia Cordata Thunb was investigated. Middle-aged women were examined over a period of 8 weeks (n=30). Participants were divided into four group: Houttuynia Cordata Thunb Exercise (HCE, n=7), Placebo Exercise (PE, n=8), Houttuynia Cordata Thunb Non Exercise (HCNE, n=8), and Placebo Non Exercise (PNE, n=7). Participants in Houttuynia Cordata Thunb groups were received 4.5 g Houttuynia Cordata Thunb and in placebo groups were received same dose of placebo thrice daily with meals. The result after 8 weeks demonstrated that HCE significant decreased visceral fat than PNE. Our present study provides the evidence that Houttuynia Cordata Thunb intake and exercise performance may reduce visceral fat and further studies with larger numbers of subjects are warranted to conclusively demonstrate effectiveness.

  • Sulgidduk samples made with additions of 2, 4, 6, 8, and 10% Houttuynia cordata Thunb. powder, and a control were examined for quality characteristics such as moisture content, water activity, color, gelatinization properties, textural characteristics, and sensory qualities in order to determine the optimal ratio of Houttuynia cordata Thunb. powder in the formulation. The moisture contents among the samples ranged from 41.98% to 44.97%, and increased as the content of Houttuynia cordata Thunb. powder increased. The water activities of the samples were not significantly different. As the Houttuynia cordata Thunb. powder content increased, the redness and yellowness of the samples also increased, but lightness decreased. For the gelatinization properties, the additions of Houttuynia cordata Thunb. powder caused decreases in peak viscosity (P) and holding strength viscosity (H). Furthermore, final viscosity (F), setback, and time to peak viscosity decreased with increasing Houttuynia cordata Thunb. powder content; however, breakdown and temperature to peak viscosity were not significantly different among the samples. Hardness and gumminess decreased with increasing Houttuynia cordata Thunb. powder content, and adhesiveness, cohesiveness, chewiness, and resilience also tended to decrease; however, springiness was not significantly different among the samples. In the consumer acceptance test, as the content of Houttuynia cordata Thunb. powder increased, the scores of all evaluated characteristics decreased; while the characteristic intensity ratings showed the reverse effect, and the 2 and 4% Houttuynia cordata Thunb. powder samples obtained fairly good scores. In conclusion, the results indicate that adding $2{\sim}4%$ Houttuynia cordata Thunb. powder to Sulgidduk is optimal, providing good physiological properties and reasonably high overall consumer acceptability.

  • Euonymus alatus(Thunb.) Sieb has been used for cancer theraphy such as Liver cancer, esophagus cancer, stomach cancer, and uterine cancer in folk. Eupolyphaga simemsis(ES) extracted from Euonymus alatus(Thunb.) Sieb increases HDL-C/TC ratio and LCAT activity. TGF-${\beta}$ and Insulin has been Knoen as factors to induce the supression of proliferation of Hep3B, Human hepatoblastoma cell. Plasma HDL3-C involved in carbohydrate methabolism in the liver was maintained in low level by Euonymus alatus(Thunb.) Sieb. The low level of plasma HDL3-C suppresses the transition from normal liver to Fat liver. Finally, this resuly in suppression of cancer in liver. In this study, Euonymus alatus(Thunb.) Sieb showed higher cell toxicity in hepatoblastoma cell(Hep3B) compared to the uterine cancer cell(HeLa). This means Euonymus alatus(Thunb.) Sieb seems not to affect in the all kinds of cancer. In future, we will study whether Euonymus alatus(Thunb.) Sleb have an effect on the liver cancer induced by virus and hepatocellular carcinoma. Also, the mechanims of suppression of cell proliferation in HCC need to investigated.

  • This study was conducted to investigate the anti-obesity effect of Discorea Japonica Thunb. fermented with Monascus After inducing obesity by feeding hight fat diet (diet induced obesity model: DIO) for four weeks, each 8 rats were assigned to normal (Nor), high fat diet (HF), high fat diet containing orlistat (PC), high fat diet containing different concentration of Discorea Japonica Thunb. fermented with Monascus (UPDM_L, UPDM_H) and Discorea Japonica Thunb. (UPD) extract. Although the UPD, UPDM_L (ultrafine pulverized Discorea Japonica Thunb. fermented with Monascus: 400 mg/kg) and UPDM_H (DIO oral administration ultrafine pulverized Discorea Japonica Thunb. fermented with Monascus: 800 mg/kg) showed weight gain inhibition effects, the results of poor obesity inhibition rather than PC were confirmed. However, it showed a more effective weight loss effect in UPDM_H than UPD, and significantly reduced the weight of epididymal fat and subcutaneous fat. Furthermore, the possibility of anti-obesity effects of Discorea Japonica Thunb. fermented with Monascus can be confirmed by observing the effects of reducing serum total cholesterol, triglyceride and LDL concentrations, reducing ALT and AST levels, and inhibiting fat build-up in liver tissue. It is believed that Discorea Japonica Thunb. fermented with Monascus can be expected to utilize as a functional material that is important to improve anti-obesity and metabolic syndrome.

  • This study evaluates the effect of Dioscorea japonica Thunb subfractions on hyperglycemia and the composition of energy metabolites in diabetic rats. Diabetes emllitus was induced in male Sprague-Dawley rats by an injection of streptozotocin(STZ) dissolved in a citrate buffer into the tail vein at a dose of 45㎎/㎏ of body weight. Diabetic rats were assigned to 6 groups; STZ-control, subfraction A, B , C, D and E groups. All groups were fed an AIN-76 diet. The second butanol fraction of Dioscorea administered orally with carboxymethyl cellucose for 10 days after the STZ injection Body weight gain, diet intake and organ weights were monitored Levels of hematocrit, blood glucose, liver and muscle glycogen were measured. Levels of cholesterol, triglycerides and free fatty acids were also assayed. Body weight losses were observed by subfraction A group. Liver and kidney weights were not affected in any of the subgractioned groups. The decrease of blood glucose in daibetic rats which were fed Dioscorea japonica Thunb was significantly greater than the dicrease of blood glucose in the STZ-control group. cholesterol plasma level was not influenced in any subfraction of Dioscorea japonica Thunb. Liver triglyceride levels were significantly lowered in subfraction A compared with the STZ-control group. This study's results suggest that oral administration of subfraction C of Dioscorea japonica Thunb frction is capabl of reducing blood glucose, plasma triglyceride and free fatty acid levels, and therefore Dioscorea japonica Thunb may contain antihyperglycemic compounds.

  • Houttuynia cordata Thunb powder (0.05 g) was placed in a stainless vessel containing 10 mL of water, and subcritical water (SCW) extraction was carried out at various temperatures (50, 100, 200, and $300^{\circ}C$) for 10, 30, and 60 min. SCW treatment significantly affected physiologically important compounds, antioxidant activity, and acetylcholinesterase inhibitory activity of H. cordata Thunb extracts. H. cordata Thunb extracted at $300^{\circ}C$ for 30 min had the highest quercetin content, DPPH radical scavenging activity, total phenolic content, and acetylcholinesterase inhibitory activity, whereas the extract at $100^{\circ}C$ for 10 min possessed the highest flavonoid content. The highest ABTS radical scavenging activity was found in H. cordata Thunb extracted at 200 and $300^{\circ}C$ for 60 min. These results indicate that SCW extraction might be a useful processing method for obtaining valuable materials from H. cordata Thunb.
