Acetone effects on N-(3,5-dichlorophenyl)succinimide-induced nephrotoxicity.

Acetone has been shown to potentiate the toxicity of many halogenated hydrocarbons. The purpose of this study was to determine if acetone could alter the acute nephrotoxicity produced by the experimental fungicide N-(3,5-dichlorophenyl)succinimide (NDPS). Male Fischer 344 rats were administered acetone (1, 5 or 10 mmol/kg) or acetone vehicle (corn oil, 10 mg/kg) orally followed 16 h later by a single intraperitoneal injection of NDPS (0.2 or 0.4 mmol/kg) or NDPS vehicle (sesame oil, 2.5 ml/kg) and renal function was monitored at 24 and 48 h. Acetone (1 or 5 mmol/kg) did not alter NDPS (0.2 mmol/kg)-induced renal effects while acetone (10 mmol/kg) pretreatment attenuated NDPS (0.4 mmol/kg)-induced increases in blood urea nitrogen (BUN) concentration and kidney weight but had no effect on NDPS (0.4 mol/kg)-induced changes in urine volume or content, organic ion accumulation by renal cortical slices or renal morphology. These results suggest that acetone weakly attenuates NDPS-induced nephrotoxicity.
