title: Effect of taurine on toxicity of cadmium in rats.
abstract: A study was undertaken to investigate the effect of taurine on the toxicity of cadmium in male Wistar rats. The rats were divided into six groups and fed different diets with or without supplement of 5% taurine and 150-300 ppm cadmium for 2 months. It was found that the body weight of rats, the ratios of liver and kidney weight to body weight, and the level of glutathione in the liver were decreased with increasing the dose of cadmium. The levels of cadmium in the liver and kidney, the levels of thiobarbituric acid-relative substances (TBARS) in the plasma and liver, the activities of aspartate transaminase (AST) and alanine transaminase (ALT) in the plasma, and the levels of blood urea nitrogen (BUN) and creatinine in the plasma of rats were increased with the increasing dose of cadmium. Hence, symptoms of cadmium toxicity in rats included loss of body weight, hepatotoxicity and nephrotoxicity. However, these toxic effects of cadmium were significantly reduced when the rats fed diet with supplement of taurine. Furthermore, the level of cadmium in the feces of rats treated with taurine and cadmium was higher than that of rats treated with cadmium alone. It indicated that taurine might play a role in reducing the toxic effect of cadmium in rats.
