- Abstract
Activity of tubular lysosomic (N-acetyl-beta-D-glucosaminidase--NAG, its thermostable isoenzyme NAG B and B-galactosidase--beta-GAL) and mitochondrial (L-canavanine: ornithine amidinetransferase--COAT) enzymes were measured in urine of 30 patients with diabetes complicated by diabetic nephropathy (DN). It was shown that activity of NAG, especially its thermostable isoenzyme NAG B and also beta-GAL in urine of DN patients was higher compare to those in healthy subject. Moreover COAT activity was registered in urine of DN patients while it is not presented in healthy persons. The precise dependence of NAG, NAG B, beta-GAL levels and COAT activity on the functional state of renal parenchyma in particular on tubular nephron nephrocytes was found that allows us to consider the given parameters as markers of diabetic process progressing in kidneys in patients with diabetes.
