Establishment and evaluation of the cadmium-induced mouse model of chronic renal failure / 第三军医大学学报

ABSTRACT

Young Kunming mice were fed with the food containing mercuric chloride, lithium carbonate, lead acetate or cadmium chloride for 45 days. It was found that these 4 salts of metals could all result in different degrees of functional and structural damages of the kidneys of the mice. In the mercuric chloride and lead acetate groups. the liver and the duodenum were also severely damaged besides the renal damages and the mice suffered a high mortality during the period of taking the toxicants. In the lithium carbonate group, the mortality was also very high but the histological damages of the kidneys were less severe. In the cadmium chloride group, the renal damages were more severe than in the other 3 groups, the mortality of the mice was relatively low, the histology of the heart, the liver and the duodenum was essentially normal, and the renal damages became worse even the toxicant was stopped. It is concluded that cadmium chloride is the agent of choice to establish the mouse model of chronic renal failure.
