| Abstract: | Urinary N-acetyl-beta-D-glucosaminidase (NAG) was measured in patients with hyperthyroidism. The value of urinary NAG in these patients was higher than that in normal subjects and diabetic patients without diabetic nephropathy. This high level of urinary NAG in patients with hyperthyroidism decreased to the level of normal subjects after treatment of hyperthyroidism. Why urinary NAG increases in the patients with hyperthyroidism remains unknown. On the occasion of estimating the significance of the high level of urinary NAG, however, the possibility of the existence of hyperthyroidism has to be considered in addition to renal damage or hyperglycemia which have already been found to increase urinary NAG. |
