【摘要】 为了研究尿液微量转铁蛋白（ＴＲＦ）与糖尿病早期肾功能损害的关系，用速率免疫散射比浊法测定了６１例非胰岛素依赖型糖尿病（ＮＩＤＤＭ）和４０例正常对照的尿液ＴＲＦ。结果显示，ＮＩＤＤＭ病人尿液ＴＲＦ显著高于正常对照组（Ｐ＜０．００１），其增高程度与ＮＩＤＤＭ病人年龄、病程、血糖水平、高血压和视网膜病变程度关系密切。尿液ＴＲＦ与微量白蛋白（ｍＡ）和Ｎ－乙酰－β－Ｄ－氨基葡萄糖苷酶（ＮＡＧ）呈显著正相关，且尿ＴＲＦ升高幅度较尿ｍＡ和ＮＡＧ增幅大。提示尿液ＴＲＦ测定是预测ＮＩＤＤＭ早期肾病的敏感指标。更多还原

【Abstract】 We studied the relationship between the urinary microtransferrin (TRF) and early glomerular damage in diabetes mellitus. 61 patients with non insulin dependent diabetes mellitus and 40 healthy subjects were measured for urinary TRF with rate immunonephelometry assay. The Urinary TRF concentrations were found to be greatly elevated in patients with diabetes compared with those in the health subjects ( P <0.001). The increase of TRF was closely related to age and duration of diabetes mellitus, blood glucose, hypertension, retinopathy, and it was initial parameter to predict diabetic nephropathy. There was a significant correlation among urinary TRF concentration, microalbumin, and N acetyl β D glucosaminidase. The urinary excretion of TRF was more elevated than that of microalbumin. It is suggested that excretion of TRF in urine is a more sensitive index of the glomerular dysfunction in diabetes mellitus.更多还原
