Effects of Pueraria radix in Water Extract on the Detoxification in Rat administered with Cadmium

This study was designed to investigates the effects of Korean pueraris radix water extract in Cd(cadmium) administered rats. Forty male Sprague-Dawley rats weighing were used for this experiment and divided into following 4 groups; control group, 3% pueraria radix in water extract group, 50 ppm Cd group, 50ppm Cd group with 3% pueraria radix in water extract group. The Cd administered rats were given 50 ppm of disolved in the distilled water. The Cd content in the rats tissue of Cd administered group was lower than in the rats tissue of Cd group with 3% pueraria radix in water extract group. Plasma levels of renin activity was increased by Cd administration group, compared with 3% pueraria radix in water extract group and Cd administred group. Glutamate oxaloacetate transaminase(GOT) and Glutamate pyruvate transaminase(GPT) were increased in Cd-administered group and lower in the 3% extracts of pueraria radix in water extract group. Lactate dehydrogenase(LDHase) was lower in the 3% extracts of pueraria radix-Cd group than in the Cd group. This results suggested that pueraria radix in water extract group, has a lowering effects on the accumulation of Cd and it is belived that the pueraria radix in water extract group has some protective effects to Cd administered in rats, but the mechanism of these effects was obscure.
