title: [Excretion of beta-N-acetylglucosaminidase in urine in type I and type II diabetic patients with and without nephropathy].
abstract: The clinical aspects of the excretion of beta-N-acetylglucosaminidase (beta-NAG, EC 3.2.1.30) in urine of type I and type II diabetics with and without nephropathy are evaluated. Correlation between concentration of albumin and of beta-NAG activity in urine is determined and the circadian rhythm of beta-NAG excretion in urine is examined, the indication of glomerular and tubulointerstitial damage is discussed. Longitudinal studies should demonstrate, whether an increased beta-NAG activity in urine of diabetics with normoalbuminuria is an indicator of nephropathy or a predictor of nephropathy if raised albuminuria is observed.
