研究中药降糖复方水提取物对KK-Ay小鼠AGEs和RAGE的影响。将自发性2型糖尿病模型KK-Ay小鼠随机分成5组:模型组、二甲双胍组、中药降糖复方低、中、高剂量组。另外,C57BL/6J小鼠作为正常对照组。其中二甲双胍组灌胃盐酸二甲双胍250 mg·kg~(-1);中药降糖复方低、中、高剂量组分别灌胃水提取物2,4,8 g·kg~(-1);正常对照组和模型组灌胃等体积蒸馏水,每日1次,共12周。实验过程中分别对小鼠血清中及(或)尿液中的谷丙转氨酶(alanine aminotransferase,ALT)、肌酐(creatinine,Cr)、血清尿素氮(urea nitrogen,BUN)、糖基化终末端产物(advanced glycation end products,AGEs)及糖基化终末端产物受体(receptor of glycation end products,RAGE)等进行检测。于灌胃12周后处死小鼠,取小鼠肾脏做病理切片及免疫组化,同时取肾组织做蛋白印记法Western blot、荧光实时定量PCR、酶联免疫吸附测定法ELISA检测AGEs,RAGE,过氧化氢酶(Cata-lase,CAT...
【英文摘要】
To elucidate the efficacy of Jiangtang decoction( JTD) on AGEs-RAGE and oxidative stress in type 2 diabetic model KKAy mice. Fifty KK-Ay mice were randomly divided into 5 groups as follows: model group,metformin group,low-dose,medium-dose and high-dose of JTD group,with 10 C57BL/6J as normal group. All groups are orally administrated with equal distilled water,250 mg·kg~(-1) metformin hydrochloride,2,4,8 g·kg~(-1)JTD,equal distilled water respectively,once per day for 12 weeks. Alanine aminotransferase( ALT...
