title: N-acetyl-beta-D-glucosaminidase activity in serum, kidney and liver of streptozotocin-induced diabetic rat.
abstract: Serum N-acetyl-beta-D-glucosaminidase (NAG) activity in streptozotocin-induced diabetic rats was significantly increased. There was neither a difference in total NAG activity in kidney and liver, nor in optimal pH of NAG in serum, kidney and liver between diabetic and control rats. The ratio of the thermounstable fraction of NAG increased in diabetic kidney and liver, while there was no difference in thermostability of between diabetic and control rats. Isoelectricfocusing of diabetic serum NAG indicated an increase in the neutral form. That of kidney and liver NAG indicated an increase in the acid form. These results may suggest that NAG clearance from the serum is decreased diabetic state.
