The relative merits of a comprehensive series of contemporary methods for detection of acute nephrotoxicity were evaluated. Male Sprague-Dawley rats were given 0, 0.25, 0.5, 1.0, or 30.0 mg mercuric chloride (HgCl2)/kg body weight by ip injection. Indices of nephrotoxicity were examined 8, 24, 48, 72, and 96 h later. Alterations in urine osmolality, volume, and protein levels were seen within 24 h in response to 1 mg/kg or more of HgCl2. Administration of 0.5-3.0 mg/kg produced dose-dependent increases in urinary excretion of maltase activity and glucose by 24 h, the period of peak effect. There was no increase in maltase or alkaline phosphatase (AP) activity in the serum of these animals. Enzymuria was not apparent in rats that had marked elevations in serum AP, argininosuccinate lyase, and ornithine carbamyl transferase activities as a result of physical (i.e., dichlorodifluoromethane-frozen) or chemical (carbon tetrachloride-induced) damage of the liver.
