Protective Effect of Leek(Allium Odorum L.) on the Cadmium Poisoning in Rats

카드뮴 독성에 대한 부추(Allium Odorum L.)의 방어효과

This study aimed to find out the effect of freeze-drying leek against cadmium poisoning on the cholesterol and enzyme activities in serum and superoxide radical, SOD and catalase in liver and kidney of the male rats during the administrered period. In this experiment, male rats of Sprague-Dawley strain were used. The rats were divided into 3 groups which were fed differently either for 5 weeks or for 10 weeks:basal diet, basal diet and cadmium in water and 3 % leek added diet and cadmium in water. Cadmium was administered ad libiturn 100 ppm CdCl$_{2}$ in water. The followings are the results of this experiment. 1. Leek reduced the cholesterol and the activities of GPT increase resulted from cadmium treatment. 2. Leek reduced the rate of cadmium in liver and kidney. 3. Leek reduced the activities of SOR and catalase in liver and kidney, while it enhanced the activities of SOD. 4. Leek reduced the necrosis and swelling in liver and kidney casused by cadmium treatment. This experiment showed that leek-addition group had protective effect against cadmium poisoning and increased ALPase activities in serum. Leek alleviated GPT activities in serum and cadmium concentration, necrosis, and swelling in liver and kidney. Therefore, this experiment concluded that leek has defensive power against cadmium poisoning.
