Effects and mechanism ofandrographolide on diabetic nephropathy mice

  • 摘要: 利用自发2型糖尿病基因工程Leprdb/db小鼠糖尿病小鼠模型,探讨穿心莲内酯(andrographolide,Andro)对糖尿病肾病的作用及机制。利用试剂盒检测Andro治疗Leprdb/db小鼠24 h后的尿蛋白、血肌酐和血尿素氮水平;利用HE染色和PAS染色分别检测Andro对糖尿病小鼠肾脏组织的病理改变和还原糖水平的影响;采用免疫组织化学染色法检测Andro对Leprdb/db小鼠肾脏的纤维粘连蛋白(FN)和NOX-4的影响。结果显示,Andro治疗组(1 mg/kg,ip)的24 h后Leprdb/db小鼠的尿蛋白、血肌酐和血尿素氮等生化指标水平明显低于对照组,Andro能抑制Leprdb/db小鼠肾脏的病理改变和FN、NOX-4的表达,表明Andro可以显著改善自发2型糖尿病基因工程小鼠Leprdb/db小鼠的糖尿病肾病。
    Abstract: To investigate the effects and mechanism of andrographolide(Andro)on type II diabetic nephropathy in Leprdb/dbmice, levels of urinary protein, serum creatinine and blood urea nitrogen after 24 h of Andro(1 mg/kg, ip)treatment on Leprdb/db mice were measured by kit. The changes on renal pathology and sugar levels in diabetic mice treated by Andro were observed by HE staining and PAS staining. The expression of fibronectin(FN)and NOX-4 protein were analyzed by immunofluorescence. Results showed that levels of urinary protein, serum creatinine and blood urea nitrogenin Leprdb / db mice after Andro treatment for 24 h were significantly lower than those of the control group. Kidney pathologic change was inhibited, and FN and NOX-4 expression were markedly decrease in the Andro group. In conclusion, Andro can significantly reduce the diabetic nephropathy in Leprdb/db mice with spontaneous type II diabetes mellitus.
