    • A screening method for detecting renal lesions in diabetic patients not yet exhibiting symptoms of nephropathy, comprising administering a predetermined dose of parathyroid hormone, analogue thereof or derivative thereof to the patients with an albumin excretion rate (AER) of microalbumin being below 15 .mu.g/min., measuring urinary excreted N-acetyl-.beta.-D-glucosaminidase (NAG) and urinary creatinine in urinary samples taken 60.+-.10 minutes before and after administration of PTH, and monitoring the increased ratio of urinary excreted NAG (U/g Cr) in post-administration of PTH to the urinary excreted NAG (U/g Cr) in pre-administration of PTH for a value less than 2.3. The screening method provides the possibility of detecting renal lesions without clinical signs of diabetic nephropathy, using a preparation essentially consisting of active ingredient of PTH.
    • PCT No.PCT / JP93 / 00178 Sec。 371 1995年9月19日第 102(e)1995年9月19日PCT 1993年2月12日提交PCT未检测出肾病症状的糖尿病患者的肾脏损害检测方法,其特征在于,向患者施用预定量的甲状旁腺激素,其类似物或其衍生物 微量白蛋白的白蛋白排泄率(AER)低于15μg/ min,在尿样中测量尿排泄的N-乙酰基-β-D-氨基葡萄糖苷酶(NAG)和尿肌酐,在前后60±10分钟内摄取 给予PTH,并监测在PTH给药前尿中排泄的NAG(U / g Cr)与PTH前期尿液排泄的NAG(U / g Cr)的比例增加,小于2.3。 筛选方法提供了检测肾病变的可能性,没有糖尿病肾病的临床体征,使用基本上由PTH活性成分组成的制剂。
