This study was carried out to evaluate antitoxic effects Taraxaci Herba extract against Cadium by calorimetric methods. The antitoxic activity of Taraxaci Herba ex tract in NIH 3T3 fibroblasts was evaluated by MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-phenyl-2H-tetrazoliumbromide), NR (Neutral red) and SRB (Sulforhodamine B protein) assay. 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 Taraxaci Herba extract was shown significant antitoxic activity. The number of NIH 3T3 fibroblasts were antitoxic and tend to regenerate. These results suggest that Taraxaci Herba extract retains a potential antitoxic activity.

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 components in the water extract of the roots of Trichosanthes kirilowii (Cucurbitaceae). The results were as follows: Generally, detoxication effects by the water extract of T. kirilowii increased in proportion to the concentrations. Experimental animals were treated with cadmium and T. kirilowii water extract by oral administration. When 40 mg/kg dosage of T. kirilowii extract was administrated it showed the highest antitoxic effects in metallothionein induction. After the water extract treatment, body weights did not increase in proportion to the extract concentrations. These results suggest that T. kirilowii extract increased metallothionein concentration and decreased the toxicity of cadmium in rats. In vitro the antitoxic activity of water extract of T. kirilowii on NIH 3T3 fibroblasts was evaluated by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide) 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 T. kirilowii extract was shown significant antitoxic activity. The number of NIH 3T3 fibroblasts were increased and tend to regenerate. These results suggest that T. kirilowii extract retains a potential antitoxic activity.

The aim of this study was to assess the antitoxic compounds, flavanones(Leachianone A=LA and Sophoraflavanone G=SFG), from Sophora flavescens(S. flavescens). We investigated the possibility of antitoxicity of LA and SFG against NIH 3T3 fibroblasts cell lines using calorimetric MTT[3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl -2H-tetra-azolium bromide] assay. The results were as follows : After cadmium was treated against NIH 3T3 cell lines, we determined IC$\_$50/. Accordingly we have examined the detoxification effects of S. flavescens, LA and SFG under cadmium IC$\_$50/=12.5$\mu$M and was carried out to observe morphological changes by the light microscopic study In NIH 3T3 cells, Sophora flavescens, LA, SFG and LA + SFG showed inhibitory effects on the cytotoxicity of cadmium and these detoxication effects increased in proportion to the concentration of these drugs. These results suggest that LA and SFG from S. flavescens retain a potential antitoxic activity.

Cordyceps species has been used as antiinflammatory, antitoxic, diuretic in folk remedies. Recent research has been reported the effect of anticancer, antidiabetic, antimutagenic, antilipid peroxidation. We examined the antidiabetic activity of cultivated Cordyceps pruinosa on streptozotocin-induced diabetic rats. The blood glucose level was recovered by treatment with Cordyceps pruinosa ethanol extract. The contents of GPT, total cholesterol and xanthine oxidase, glutathione peroxidase, catalase activities of the cytosol were significantly decreased as compared to the diabetic group. (omitted)

The antioxidative activity was observed in the ethyl acetate extract $(IC_{50},\;119{\pm}0.16\;{\mu}g/mL)$ from Pueraria thunbergiana. The DPPH radical scavenging effect of this extract was comparable with that of synthetic antioxdant, BHA $(IC_{50},\;88.39{\pm}1.1\;{\mu}g/mL){\times}\;10^{-3}\;{\mu}M$. Pueraria thunbergiana extracts against microorganisms were evaluated in terms of the minimum inhibitory concentrations (MIC). In general, C. albicans was stronger antimicrobial activity than the other microorganisms. in vitro the antitoxic activity of extracts of Pueraria thunbergiana on NIH 373 fibroblasts was evaluated by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide) method. Generally, detoxification effect by the extracts of Pueraria thunbergiana increased in proportion to the concentrations. When $10\;{\mu}g/mL$ of the hexane extract of Pueraria thunbergiana was treated it showed the highest antitoxic effects (p<0.01). These results suggest that the crude extract of P. thunbergiana has a potential therapeutic activity.
