This study was performed to investigate the antitoxic component in methanol fraction of Lonicerae fios. The results were as follows: 1. When a 500 ppm of water soluble fraction of Lonicerae flos was administered, it showed the highest antitoxic effect. 2. Generally, detoxication effects by methanol fraction of Lonicerae fios increased. When the ethyl acetate soluble fraction of Lonicerae rios was administered, it exhibited the highest antitoxic effect against the toxicity of cadmium in Liver. 3. The combined administration of cadmium and methanol fraction of Lonicerae rios significantly increased metallothionein in liver compared to administration of cadmium only. This phenomenon was more remarkable when the ethyl acetate soluble fraction of Lonicerae fios was administered with cadmium chloride.

This study was carried out to evaluate antitoxic effects Palsun Brewing Water against cadmium by colorimetric methods. The antitoxic activity of Palsun Brewing Water in NIH-3T3 fibroblasts was evaluated by MTT ({3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl-2H-tetrazoliumbromide} and SRB (sulforhodamine B protein) assays. The light microcopic 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 Palsun Brewing Water was shown significant antitoxic activity against E. coli endotoxin and Salmonella endotoxin. The number of NIH-3T3 fibroblasts were antitoxin and tend to regenerate. These results suggest that Palsun Brewing Water retains a potential antitoxic activity.

This study was conducted to investigate the metallothionein (MT) induction by Panax ginseng C. A. Meyer in cadmium chloride intoxication. The results were as follows: Generally, detoxicatlon effects by Panax ginseng C. A. Meyer extract increased proportionally to the increase of cadmium concentrations. When a 8 mg/g dosage of cadmium was administered, formation of the cadmium and EDTA complex showed the highest antitoxic effect. Also, when a 4 mg/g dosage of cadmium was administered, Panax ginseng C. A. Meyer extract showed the highest antitoxic effect in metallothionein induction. According to the above results, Panax ginseng C. A. Meyer extract administered with cadmium increased metallothionein concentration and decreased the toxicity of cadmium in liver.

This study was conducted to investigate the metallothionein (MT) induction by Lonicerae rios in cadmium chloride intoxication. The results were as follows: Generally, detoxication effects by Lonicerae fios extract increased to the increase of extract concentrations. When 90 mg/kg dosage of Lonicerae fios extract was administered, it showed the highest antitoxic effects in metallothionein induction. From the above results, Lonicerae rios extract increased metallothionein concentration and decreased the toxicity of cadmium in liver.

This study was conducted to investigate the antitoxic component in methanol extract of Houttuynia cordata $T_{HUNB}$. The results were as follows: Generally, detoxication effects by Houttuynia cordata $T_{HUNB}$ methanol extract increased in proportion to the methanol extract concentrations. When 40 mg/kg dosage of Houttuynia cordata $T_{HUNB}$ methanol extract was administrated, it showed the highest antitoxic effects in metallothionein induction. After the methanol extract treatment. Body weights increased in proportion to methanol extract concentrations. However, after 3 weeks, the body weight decreased insignificantly. From the above results, these results suggest that the methanol extract of Houttuynia cordata $T_{HUNB}$ increased metallothionein concentration and decreased the toxicity of cadmium in rats.

A study on the antitoxic effects of Semen Mungo extracts against Cadmium Chloride Toxicity in Rats This study was performed to find out the effect of Semen mungo against Cadmium toxicity. The experimental rats were divided into 5 groups such as control group, Cadmium alone treatment group, three simultaneous treatment groups of semen mungo and cadmium. Rats were given pellets administration with three dosage of semen mungo glabrae such as 4mg/kg body weight for four weeks. The results were summarized as follows on: ' 1. The simultaneously administration of semen mungo and cadmium significantly more decreased cadmium concentration in liver and kidney tissues compared to the administration of cadmium alone.(p<0.05) 2. The simultaneously administration of semen mungo and cadmium significantly more decreased metallothionein concentration in liver and kidney tissues compared to administration of cadmium alone(p<0.05) 3. When liver and kidney tissues were observed with optical microscope obvious changes were visible in those tissues.1

A study on the antitoxic effects of Herba Taraxaci extracts against Cadmium Chloride Toxicity in Rats. This study was performed to find out the effect of taraxacum platy carpum against Cadmium toxicity. The experimental rats were divided into 5 groups such as control group, Cadmium alone treatment group, three simultaneous treatment groups of taraxacum platy carpum and cadmium. Rat were given pellets administration with three dosage of taraxacum platy carpum such as 4 mg/kg body weight for four weeks. The results were summarized as follows on: 1. The simultaneously administration of taraxacum platy carpum and cadmium significantly more decreased cadmium concentration in liver and kidney tissues compared to the administration of cadmium alone. (p<0.05) 2. The simultaneously administration of taraxacum platy carpum and cadmium significantly more increased metallothionein concentration in liver and kidney tissues compared to administration alone.

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)

This study was carried out to develop the antitoxic compound about cytotoxicity of cadmium on cultured rat neuroglial cells. These cells divided into 3 groups; control group (medium only) or $MTT_{50}$ group (neuroglial cell, $61{\mu}M$ cadmium) and experimental group ($61{\mu}M$ caffeic acid). Neutral red (NR) and tetrazolium MTT of the colorimetric assay were performed to evaluate the cytotoxicity of cell organelles. The light microscopic study was carried out to morphological changes of cultured rat neuroglical cells. The results indicated that caffeic acid showed detoxification effect on cytotoxicity of cadmium in $61{\mu}M$ concentration. According to the spectroscopic study of 1:1 complex of cadmium and caffeic acid, it showed that this formation of complex eliminated cadmium from cultured rat neurogllal cells.
