This study was designed to investigate the effects of Korean Gu-Gi-Ja tea on plasma hormone such as renin and aldosterone water in cadmium administered rats. The cadmium administered rats were given 50 ppm and 100 ppm of CdCl$_2$.2$H_2O$ disolved in the distilled water. Sixty male Sprague-Dawley rats weighing 100$\pm$10 g were divided into 6 groups according to body weight. The control group was fed standard diet without cadmium. The experimental groups, which were fed standard diet containing 50 ppm and 100 ppm cadmium and Gu-Gi-Ja tea group. The results of this study were as follows; food intake, body weight gain and kidney weight content in cadmium administered groups were lower than those in Gu-Gi-Ja tea group. The contents of cadmium in kidney of the rats were determined by using ICP (Inductively Coupled Plasma Spectrcphotometer). In kidney accumulation of Gu-Gi-Ja tea groups were lower than those in cadmium administered group. Plasma levels of renin activity was increased by Cadmium administration group, compared with Gu-Gi-Ja tea and cadmium administred group. Plasma levels of aldosterone activity was increased by cadmium administration group, compared with Gu-Gi-Ja tea and cadmium administred group. This results suggested that Gu-Gi-Ja tea has a lowering effects on the accumulation of cadmium in kidney and it is believed that the Gu-Gi-Ja tea has some protective effects to cadmium administered lenin and aldosterone hormone in rats, but the mechanism of these effects was obscure.
