The progression of changes in rabbit kidney function following dosing with the nephrotoxin S-(1,2-dichlorovinyl)-L-cysteine (DCVC, 20-50 mg/kg) was determined. Proteinuria was observed 0.5-1 hr after administration of DCVC at doses of 20 -50 mg/kg. Blood urea nitrogen levels, glomerular filtration rates, urinary glucose excretion, and urine volume were also altered following DCVC dosing; however, these parameters were less sensitive than proteinuria as markers of early renal dysfunction. None of these latter four indicators were affected by low DCVC doses, nor were they altered by high DCVC doses until 1.5-2.5 hr after dosing. Dose-dependent morphological changes to kidney structure were also observed 5 hr after DCVC administration. Low doses caused damage restricted to brush border membranes in the pars recta, while higher doses produced a necrotic lesion encompassing all regions of the proximal tubule. This study indicates that DCVC can cause rapid renal dysfunctional changes which are first detected by elevated urinary protein excretion.
