[Early indicators of kidney injury in male and female rats after oral administration of cadmium].

Abstract

The effect of cadmium on the urinary excretion of glucose, creatinine and enzymes has been studied in adult male and female rats given the substance (70, 140 and 280 mg/kg food) for 4 weeks. Renal function tests and gel electrophoresis of urinary proteins were conducted simultaneously. Sex-dependent differences were demonstrated with regard to sensitivity of several kidney parameters and their predictive character of a possible chronic nephrotoxicity. These results were compared with hematological and general biological examinations of cadmium toxicity.
