Activity of some lysosomal enzymes in peritoneal lymphocytes from patients with terminal renal failure treated by intermittent peritoneal dialysis.

Acid phosphatase (AcP), beta-glucuronidase (GR) and N-acetyl-beta-D-glucosaminidase (NAG) activity was determined, using semiquantitative cytochemical methods, in the peritoneal fluid lymphocytes obtained from 50 patients with terminal renal failure treated by intermittent peritoneal dialysis. The control group included 30 subjects with normal renal function. The percentage of AcP and NAG-positive lymphocytes was significantly lower and that of the GR-positive cells significantly higher in dialysed patients than in the control group.
