The A, B, I1 and I2 forms of N-acetyl-beta-glucosaminidase present in urine, serum, kidney, liver and cerebral spinal fluid were separated on DEAE-cellulose and their presence confirmed by cellogel electrophoresis. The relative activities of each enzyme were determined by integrating the area under the elution peaks. 2. Serum A-form was eluted at a lower molarity of chloride than liver A-form and this was designated the As-form to distinguish it from the A-form of N-acetyl-beta-glucosaminidase found in liver and kidney. 3. The P-form of N-acetyl-beta-glucosaminidase present in the serum of a group of pregnant women was not detectable in urine samples from the same women. 4. Urinary NAG activities were found to be abnormally high in patients with impaired renal function. 5. The activity of both N-acetyl-beta-glucosaminidases A and B increased in pathological urines. The higher the total N-acetyl-beta-glucosaminidase activity excreted the higher the % of activity of the B-form present. 6. In a number of patients with haematuria an A-form similar to the serum As-form was present in the urine. | lld:pubmed |
