[Effect of calcium content of the diet on the course of cadmium poisoning].

The influence of optimum (0.6%), excessive (2.4%) and insufficient calcium content in the ration on the course of cadmium poisoning was studied in a chronic experiment on rats. Cadmium poisoning was drastically exaggerated in the presence of insufficient cadmium content in the ration of the animals, while the excessive calcium content produced a protective effect on the animals suffering from chronic cadmium poisoning.
