Evaluation of urinary enzymes in dogs with early renal disorder.
We investigated urinary N-acetyl-beta-D-glucosaminidase NAG (EC 3.2.1.30), gamma-glutamyl transpeptidase gamma-GTP (EC 2.3.2.2) and glycyl-prolyl dipeptidyl aminopeptidase GP-DAP (EC 3.4.14.5) in dogs with heartworm disease and renal failure. In the renal failure dogs, the NAG, gamma-GTP and GP-DAP index were significantly higher than those in the healthy dogs. In the heartworm disease dogs with normal chest X-rays (HW I), none of the enzyme values was significantly different from those of the healthy controls. In the dogs with heartworm disease showing abnormal heart shadows on their chest X-rays (HW II), enzyme values were significantly higher than those in the healthy dogs (P < 0.01) and the HW I dogs (P < 0.01). Thus, these urinary enzymes tests are available for the early detection of renal disorders.
