【摘要】 对49例糖尿病的24小时尿N-乙酰-β-D-氨基葡萄糖苷酶（NAG）活性、白蛋白及β₂微球蛋白,24小时尿及随机尿的NAG指数,血NAG及HbA₁进行了测定。通过糖尿病患者值与正常人值相比以及这几个指标间相关比较,认为尿NAG是糖尿病性肾病早期诊断的一个有用指梳更多还原

【Abstract】 Urinary activity of N-acetyl-β-D-glucosaminidase （NAG） and NAG: Creatinine （NAG-I） in 24-hour urine and NAG-I in a single random urine were measured in 43 diabetic subjects. The results showed that they were significantly higher in diabetics than in non-diabetic eontrols and NAG correlated with urinary albumin and β₂-microglobulin, but not with serum NAG and HbA₁. The results indicate that the urinary activity of NAG may be an early predictor for diabetic nephropathy.更多还原
