  • This study was condo더ed to investigate the antitoxic component in aqueous extract of Houttuynia cordata $T_{HUNB}$. The results were as follows: Generally, detoxification effects by Houttuynia cordata $T_{HUNB}$ extract increased in proportion to the extract concentrations in rats. When 40 mBtg dosage of Houttuynia cordata $T_{HUNB}$ extract was administrated, Houttynia cordata $T_{HUNB}$ extract showed the highest antitoxic effects in metallothionein induction. After the extract treatment, body weights increased in proportion to the extract concentrations. However, after 3 weeks, the body weight decreased insignificantly. From the above results, Houttuynia cordate $T_{HUNB}$ extract increased metallothionein concentration and decreased the toxicity of cadmium in rats. In vitro the antitoxic activity of aqueous extract of Houttuynia cordata $T_{HUNB}$ on NIH 373 fibroblasts was evaluated by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetra-zoliumbromide) and SRB (sulforhodamine B protein) assays. The light microscopic study was carried out to observe morphological changes of the treated cells. These results were obtained as follows; The concentration of 10$^{-2}$ mg/ml of Houttuynia cordata $T_{HUNB}$ extract was shown significant antitoxic activity The number of NIH 373 fibroblasts were increased and tend to regenerate. These results suggest that Houttuynia cordata THUNB extract retains a potential antitoxic activity.oxic activity.

  • This study was conducted to investigate the antitoxic agent in methanol extract of Houttuynia cordata $T_{HUNB}$. Detoxication effects By H. cordata $T_{HUNB}$ extract increased in proportion to the extract concentrations. When 40 mg/kg dosage of H. cordata $T_{HUNB}$ extract was administered, it showed the highest antitoxic effects in metallothionein induction. After the extract treatment, body weights generally increased in proportion to the extract concentrations. From the above results, H. cordata $T_{HUNB}$ extract increased metallothionein concentrations and decreased the toxicity of cadmium in rats. In vitro the antitoxic activity of methanol extract of H. cordata $T_{HUNB}$ on NIH 3T3 fibroblasts was evaluated by the MTT {3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyl-2H-tetrazoliumbromide} and SRB (sulforhodamine B protein) assays. The light microscopic study was carried out to observe morphological changes of the treated cells, $10^{-2}\;mg/ml$ Concentrations of H. cordata $T_{HUNB}$ extract was shown significant antitoxic activity. The number of NIH 3T3 fibroblasts were increased and tend to regenerate. These results suggest that H. cordata $T_{HUNB}$ extract retains a potential antitoxic activity.

  • This study was carried out to evaluate cytotoxic effects of Houttuynia cordata T/sub HUNB/ 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 ㎍/㎖ concentration of methanol extract (63.81 %) of Houttuynia cordata T/sub HUNB/ was shown significantly antitoxic activity on A549 cell lines. The order of cytotoxicity fractions of methanol from Houttuynia cordata T/sub HUNB/ extracts against cancer cell lines in vitro is as follows : hexane fraction layer > chloroform fraction layer > ethyl acetate fraction layer > buthanol fraction layer > water fraction layer. These results suggest that the hexane fraction of methanol extract from Houttuynia cordata T/sub HUNB/ extract may be a valuable choice for the development of antitumor agents.

  • Objective : This study was carried out to examine the effect of five fractions of an aqueous extract from Artemisia capillaris $T_{HUNB}$. Methods : The queous extract from Artemisia capillaris $T_{HUNB}$. was fractionized into 5 kinds of material. We observed the effect of each fractions on etoposide-induced apoptosis, cell viability, cell cycle progression and mRNA expression of apoptosis-related genes in human hepatocyte cell line HepG2. Results and Conclusions : The data shows that butanol fraction of Artemisia capillaris $T_{HUNB}$. has no relation with cell cycle, however, it inhibits apoptosis significantly and the action may be due to the suppression of Fas and Sax genes and activation of Bcl-2 gene.

  • 흰쥐에게 카드뮴 경구투여시, 어성초 전탕액의 경구 투여한 후 카드뮴의 독성에 대한 해독경감효과에 대하여 다음과 같은 결과를 얻었다. 1. 흰쥐에게 어성초 전탕액의 경구 투여 용량이 증가할수록 카드뮴의 독성에 대한 해독경감효과는 증가하였으며, 신장에서보다 간장에서 해독경감효과가 좋았다. 2. 흰쥐 신장 및 간장의 MT의 농도는 간장에서 보다 신장에서 우수한 결과를 보였으며, 신장에서는 어성초 전탕액의 경구 투여 농도가 10mg/kg 이상이 되면 MT 형성은 어성초 전탕액의 투여 농도가 증가하여도 크게 증가하지는 않았다. 3. 흰쥐의 체중변화는 어성초 전탕액의 경구 투여 용량이 증가할수록 흰쥐의 체중변화도 증가하는 경향을 보였으나, 3주 이후에는 체중의 증가가 적게 나타났다. 이상과 같이 어성초 전탕액의 경구투여를 종합해 보면, 어성초 전탕액의 경구 투여 시켰을 경우 카드뮴의 독성에 대한 해독경감효과가 있는 것으로 판단된다.

  • Several plant growth regulators were examined for on their effect on the in vitro propagation of Kalopanax pictus$(T_{HUNB}.)$ $(N_{AKAI}.)$ on WPM medium. Among the cytokinins tested, BA at $13.32\;{\mu}M$ appeared to be the most effective for multiple axillary shoot formation. Although the addition of $2.89\;{\mu}M\;GA_3$ promoted stem elongation, it produced morphologically abnormal leaves and stems. For rooting of the shoots, $4.9\;{\mu}M$ IBA seemed to be more effective than $2.69\;{\mu}M$ NAA. When the regenerated plants were transferred on artificial mixture containing vermiculite and peat-moss (1 : 1, v/v), 81% of them survived and grew normally.

  • Objectives : The purpose on this study is to show the anti-obesity effect of Eugenia caryophyllata $T_{HUNB.}$ pharmacopuncture in mice fed a high fat diet. Methods : Male ICR mice were divided into three groups, which were fed a normal AIN diet(N), a high fat diet(CT), a high fat diet and injected with 50 mg/kg of Eugenia caryophyllata $T_{HUM.}$ pharmacopuncture(EC) for 8 weeks. Results : 1. The levels of body weight gains were significantly increased in CT compared with N and decreased in EC compared with CT. 2. The levels of absolute liver weight and adipose-tissue weight were significantly decreased in EC compared with CT. The levels of relative adipose-tissue weight were significantly decreased in EC compared with CT. 3. The levels of total cholesterol(TG), triglycerid(TC), high density lipoprotein(HDL) cholesterol and low density lipoprotein(LDL) cholesterol were significantly increased in CT compared with N and decreased in EC compared with CT. The levels of HDL/LDL ratio were shown there were no significant differences in all groups. 4. The levels of adiponectin in serum were remarkably decreased in CT compared with N and significantly increased in EC compared with CT. 5. The levels of measuring adipocyte number in adipose tissue was significantly decreased in CT compared with N and increased in EC compared with CT. Conclusions : These results suggest that Eugenia Caryophyllata $T_{HUNB.}$ has an anti-obesity effect in mice and that the effect is mediated by inhibition of fat gain.
