[Urinary N-acetyl-beta-glucosaminidase as index of renal toxicity (author's transl)]

Urinary excretion of N-acetyl-beta-D-glucosaminidase (NAG) has been studied in rats submitted to potentially nephrotoxic drugs (acetylsalicylic acid, gentamicin). Both drugs induced increase in NAG excretion which was reversible and dose-dependent. The date presented in this paper suggest that urinary NAG determination may have value as screening device for the study of nephrotoxic effects in experimental toxicology.
