Urinary excretion of enzymes following repeated parenteral administration of cadmium to rats
The effect of daily parenteral administration of cadmium (0.75, 1.5, and 3.0 mg/kg) on the urinary excretion of enzymes has been studied in the young male rat. Aspartate aminotransferase, alkaline phosphatase, ..gamma..-glutamyl transpeptidase, and leucine aminopeptidase all showed an initial significant increase around the second day of dosage, the intensity of which was dose related. A second phase of enzymuria occurred later, the onset of which was dose related. High-dose-group animals (3.0 mg/kg) exhibited this increase around Day 15, while the median (1.5 mg/kg) and low- (0.75 mg/kg)dose-group animals developed enzymuria around Days 21 and 38, respectively. This second phase of elevated enzyme levels in the urine was persistent, and is believed to represent the development of renal damage.
