糖毒清治疗糖尿病肾病肾功能不全的量效学研究

Study on the Relation of Dose and Effect in Treating Diabetic Renal Insufficiency (DRI) with Tangduqing

目的探讨中药糖毒清治疗糖尿病肾病肾功能不全的最佳剂量。方法采用5/6肾切除联合腹腔注射STZ的方法建立糖尿病肾病肾功能不全大鼠模型,然后将成模大鼠随机分为模型组、正常对照组及糖毒清高、中、低剂量组,分别灌胃治疗,疗程结束后通过检测各组大鼠的肾功能及24h尿蛋白定量评价糖毒清各组的疗效,以确定糖毒清的最佳给药剂量。结果糖毒清可有效地减少肾功能不全大鼠的24h尿蛋白排出量,并降低血肌酐和尿素氮。结论糖毒清可有效地减缓糖尿病肾病肾功能不全的病理进程,其中以糖毒清中剂量组的疗效最佳。

Objective To investigate the best dose of treating diabetic renal insufficiency （DRI） with Tangduqing granules. Methods To establish model rats of DRI by the method of 5/6 nephrectomy and abdominal cavity injection with streptozotocin. The successful model rats with DRI were divided into four groups randomly： model group, high dose group, medium dose group, low dose group. Ten age-matched healthy male SD rats were served as controls （administered with NS 2 mL/d）. Ten weeks later, contents of the BUN, SCr and urine protein excretion in 24 hours were determined. And to detect the best dose of treating DRI with Tangduqing granules by evaluating the effect of Tangduqing. Results Tangduqing had the function of reducing contents of BUN, SCr and urine protein excretion in 24 hours of rats with renal insufficiency. Conlusions Tangduqing may effectively delay the development of renal failure. The therapeutic effects of medium dose group were the best.
