摘要
目的 研究红景天最细粉对糖尿病肾病(DN)大鼠的保护作用.方法 采用单侧肾脏切除并腹腔注射链脲佐菌素(STZ)的方法建立DN大鼠模型.将造模成功的大鼠按体质量排序编号,采用随机数字表法随机分为假手术组,DN模型组,红景天普通粉治疗组(3 g/kg·d-1),及红景天最细粉低剂量组(0.75 g/kg·d-1)、中剂量组(1.5 g/kg·d-1)、高剂量组(3 g/kg·d-1)各10只,均灌胃给药,1次/d.7周后,检测各组空腹血糖(FBG)、血清总胆固醇(STC)、尿素氮(BUN)、肌酐(Cr)、尿液尿蛋白(Upro);光镜观察各组肾组织的形态学改变.结果 DN模型组FBG、STC、BUN、Cr、Upro[分别为(24.78±3.66) mmol/L、(4.07±1.32) mmol/L、(22.36±2.54) mmol/L、(86.78±7.47) μmol/L、(50.23±6.82) mg],与红景天普通粉治疗组,红景天最细粉中、高剂量组的FBG[分别为(18.67±2.74) mmol/L、(17.21±3.17) mmol/L、(15.48±2.46) mmol/L]、STC[分别为(3.33±0.87) mmol/L、(3.42±0.74) mmol/L、(3.21±0.92) mmol/L],BUN[分别为(15.43±2.04) mmol/L、(16.56±1.85) mmol/L、(12.44±1.36) mmol/L]、Cr[分别为(66.17±4.43) μmol/L、(68.42±5.06) μmol/L、(61.33±4.21) μmol/L]、Upro[分别为(37.47±5.64) mg、(35.66±4.72) mg、(27.37±3.92) mg]比较均降低,差异有统计学意义(P<0.05),且红景天最细粉高剂量组的疗效更佳.DN大鼠肾组织病理形态学观察表明,各红景天治疗组肾组织病理改变均减轻.结论 红景天对DN大鼠有保护作用,且相同剂量最细粉组的疗效优于普通粉组.
Objective To study the renal protective effects of superfine powder of Rhodiola rosea in diabetic nephropathy (DN)rats.Methods The DN rats model was established by one side nephrectomy and intraperitoneal injection of streptozotocin(STZ).Then rats were randomly divided into 6 groups:sham-operation group,model group,Rhodiola rosea common powder groups(3 g/kg·d-1),and superfine powder of low,medium and high dose groups (0.75、1.5、3.0 g/kg·d 1),10 rats in each group.Rats were given the relevant drugs respectively for 7 weeks.Finally the levels of fasting blood glucose (FBG),serum total cholesterol (STC),blood urea nitrogen (BUN),creatinine (Cr) and urinary protein (Upro) were detected.The kidney tissue was taken for histopathological observation.Results Compared with DN modelgroup [FBG,STC,BUN,Cr and Upro was (24.78±3.66)mmol/L,(4.07±1.32)mmol/L,(22.36±2.54)mmol/L,(86.78±7.47) μmol/L,(50.23±6.82)mg respectively],the rats in DN model group after treatment with common and superfine powder (medium and high dose groups) of Rhodiola rosea appeared different levels of improvement ofFBG [(18.67±2.74) mmol/L,(17.21 ±3.17)mmol/L,(15.48±2.46) mmol/L],STC [(3.33±0.87) mmol/L,(3.42 ± 0.74) mmol/L,(3.21 ±0.92)mmol/L],BUN [(15.43±2.04)mmol/L,(16.56±1.85)mmol/L,(12.44±1.36)mmol/L],Cr [(66.17 ± 4.43) μmol/L,(68.42 ± 5.06) μmol/L,(61.33±4.21)μmol/L] and Upro [(37.47±5.64) mg、(35.66 ± 4.72) mg,(27.37± 3.92) mg],P< 0.05.The pathologic changes of kidney tissue were improved,too.Conclusion Rhodiola rosea has a good renal protective effect in rats with DN.Furthermore,the superfine powder is more effective than the common powder in renal protective effects.
