[Experimental cadmium poisoning].

During the past years, many publications and reviews have described kidney and bone lesions observed after human chronic cadmium poisonings of food or occupational origin. In this experiment carried out in rat fed with normal diets or polydeprived of vitamin D3, calcium and proteins, with or without addition of cadmium, the bone lesions observed are as severe in all polydeprived animals, wether treated with cadmium or not.
