摘要：The amount of calcium in the liver of rats was examined after continuous oral administration of 0.1 mg/day of lead or cadmium acetate for 30 days, and the following results were obtained. The amount of calcium in the liver increased about 3 times (p<0.01) in the lead-treated group, but decreased to about one-half (p<0.01) in the cadmium-treated group compared with control group. On the other hand, the liver calcium concentration in both lead and cadmium-treated group increased significantly compared with that of the cadmium-treated group. These data suggest that lead antagonizes the effect of cadmium on the amount of calcium in the liver of rats.
