  • This study was performed to investigate the effect of dietary protein and calcium levels on cadmium detoxication in rats. Seventy male Sprague-Dawley rats weighing 208 $\pm$ 19 g were blocked into 10 groups of 7 animals according to body weight. Five groups were fed 15% protein-0.6% calcium diet with 100ppm cadmium in drinking water for first 15days and the other 5groups fed same diet without cadmium in drinking water for same period and served as controls. After this 15-day intoxication period, each one of cadmium intoxication and control groups were fed each of 4 kinds of detoxifying diets different with protein(40%, 15%) and calcium(1.3%, 0.6%) levels without cadmimum in drinking water for following 15 days of detoxifying period. Results were summarized as follows: 1) Food intake, body weight gain, F.E.R. and weights of liver, kidney and femur were increased by detoxifying diets and high protein diet was most effective in weight gains of liver and kidney. 2) When cadmium and metallothionein contents of initial intoxication group and those of all detoxication groups were compared, cadmium and metallothionein contents in the liver were not changed, but those in kidney increased, and those in intestine decreased markedly. 3) Only dietary protein level affected cadmium and metallothionein distribution among organs, and cadmium contents of whole blood, liver, kidney and femur were lower in high protein diet, but metallothionein contents in liver and kidney were higher in high protein diet. 4) Gel filtration chromatogram showed that most of cadmium in the cytosol was bound to metallothionein fractions in high protein-high calcium group. Results obtained indicated that high protein diet was effective in cadmium detoxication by increasing the induction of metallothionein synthesis. But high calcium diet did not play a role in cadmium detoxication.

  • 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 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 of methanol fraction of Lonicerae fios increased. 'When the ethyl acetate soluble fraction of Lonicerae fios was administered, it exhibited the highest antitoxic effect against the toxicity of cadmium in spleen.

  • Detoxication effect of red ginseng extract against toxicity of methly mercury on ultrastructure of mouse liver was studied by electron microscopy. The hepatocyte of methyl mercury treatment group showed partial rupture of nucleus, mitochondrial swelling, decrease of glycogen content, and appearance of a great number of large vacuoles. While, the hepatocyte of methyl mercury-red ginseng extract treatment group showed slight mitochondrial swelling and decrease of vacuoles in size and number than those of methyl mercury treatment group.

  • We have studied the mechanism by examining the effect of ginseng on the epoxide hydrolase which is catabolized the reactive intermetabolite of bromobenzene, and bromobenzene-induced hepatotoxicity. It was observed that ginseng saponin fraction protects against bromobenzene-induced hepatotoxicity in mice as evidenced 1. increased the epoxide hydrolase activity, 2. lower serum transaminase activity, 3. decreased the formation of lipid peroxide. These results suggested that the inducing effect of ginseng on the epoxide hydrolase is believed to be a possible detoxication mechanism for the bromobenzene toxicity in mice.

  • To investigate the detoxificative effect of tea, five kinds of tea(mulberry, anaerobic treated mulberry, green, barly tea and corm tea) were selected and determined their dotoxication activities for Cd and Pb in drinking water. The effect of tea on the removal of Cd and Pb were increased proportionally to the contents of teas. Anaerobic treated mulberry leaf tea showed stronger detoxication activity than the others. In drinking water contaminated with Cd, the removal effect of Cd was high 27% by anaerobic treated mulberry leaf tea and 14% by mulberry leaf tea as compared to green tea. Also, in drinking water with Pb, the removal effect of anaerobic treated mulberry leaf tea was the best among five kinds of tea. Pretreatment method on the removal effect of Cd was better than post-treatment method in the treatment method.

  • Objective: Through the literature on the effect of Scolopendra subspinipes mutilans L. Koch, we are finding out the clinical possibility and revealing the more effective to untractable disease. Method: We investigated the literatures of Oriental Medicine and experimental reports about Scolopendra subspinipes mutilans L. Koch. Results: 1.The taste of Scolopendra subspinipes mutilans L. Koch is hot, wann and toxic, and the effect is dispelling wind, spasmolytic action and detoxication so it has been used for C.V.A, facial palsy, numbness of hands and feet, wounds and arthritis. 2. A toxic constituent of Scolopendra subspinipes mutilans L. Koch is mainly located in the 1st limbs, and we can prevent toxic symptoms, if taken a dosage moderately. 3. The pharmacological action of Scolopendra subspinipes mutilans L. Koch is anti-convulsive action, analgesic action, lowering blood pressure, anti-inflammatory action, anti-tumor action and microbe inhibition. On the study of Scolopendra subspinipes mutilans L. Koch, we thought it is effective to intractable disease, and it may be needed variable studies on toxicity and clinical effects.

  • The present work was undertaken to investigate the effect of diallyl disulfide on ethacrynic acid toxicity. Ethacrynic acid-induced morality and formation of lipid peroxide were inhibited by diallyl disulfide. Furthermore, decreasing effect of glutathione S-transferase and glutathione level in the liver by ethacrynic acid were reduced by diallyl disulfide. These results suggested that the inducing effect of diallyl disulfide on the ethacrynic acid metabolizing enzyme, glutathione S-transferase, is believed to be a possible detoxication mechanism for the ethacrynic acid toxicity in mice.

  • Glutathione s-transferase in thought to play a key role in initiating the detoxication of potential alkylating agents, including pharmacologically active compounds. It is widely accepted that garlic contained allin which is converted to allicin by allinase. Allicin is easily degraded to diallyl disulfide and other components. This report attempted to observe the effect of diallyl disulfide on some biological activities. It was observed that the activity of serum transaminase was not changed by the treatment of diallyl disulfide. The liver cytosolic glutathione s-transferase was significantly increased. where as the microsomal glutathione s-transferase was not increased.
