【摘要】 目的观察葛根素对糖尿病大鼠肾小球细胞间黏附分子ICAM-1基因表达的调控。方法利用链脲佐菌素腹腔注射法诱导建立1型糖尿病大鼠模型,将实验用SD大鼠随机分为正常对照组、糖尿病组、葛根素治疗组。治疗16周。观察治疗期间及治疗后大鼠的一般状况、血糖、尿素氮、血肌苷,内生肌苷清除率、24 h尿蛋白排泄率,原位杂交检测肾组织CD54基因表达。结果造模组大鼠均出现肾脏功能有损害;葛根素能改善基本状况,降低糖尿病大鼠的尿素氮、血肌苷、24 h尿白蛋白排泄率,增加内生肌苷清除率,细胞间黏附分子mRNA表达显著下调。结论葛根素具有确切的肾脏保护作用。更多还原

【Abstract】 Objective To observe the effect of puerarin on the ICAM-1 gene expression in streptozotocin-Induced diabetic nephropathy rats. Methods Diabetic nephropathy rats were induced by intraperitoneal injection of STZ.Rats were allocated into normal control group,model group,and puerarin group.The puerarin treatment lasted for 16 weeks.During and after the treatment,the general health conditions,blood glucose levels,blood urea nitrogen,serum creatinine,urinary albumin excretion rate of 24-hours,and clearance rate of creatinine of the rats were observed.The ICAM-1mRNA expressions were also determined by in situ hybridization analysis in the kidney tissue of the rats.Results Diabetes mellitus and renal function lesion occurred in the model group and puerarin group.Puerarin could improve the general health of the rats,decrease blood urea nitrogen,serum creatinine,and urinary albumin excretion rate of 24-hours;and increase the clearance rate of creatinine.The ICAM-1mRNA expressions in the kidney were significantly inhibited by puerarin treatment.Conclusion Puerarin has a function of renal protection.更多还原
