大黄对糖尿病大鼠肾脏ICAM-1及VCAM-1表达的影响

目的 探讨大黄对糖尿病大鼠肾脏细胞间黏附分子-1(intercellular adhesion molecular-1,ICAM-1)及血管细胞间黏附分了-1(Vascular Cell Adhesion Molecule-1,VCAM-1)表达的影响.方法 制备糖尿病大鼠模型,成模后,随机抽取24只分为模型组、大黄组各12只.大黄组给予人黄煎剂10 g(生药·kg体重-1)灌胃,正常组和模型组给予同等剂量纯净水灌胃.8周后,取肾脏制备病理切片,SP法免疫组化染色,观察ICAM-1、VCAM-1的表达.结果 大黄组、模型组ICAM -1及VCAM-1表达明显高正常组(P<0.05),大黄组肾脏ICAM-1、VCAM-1表达弱于模型组(P<0.05).结论 大黄能抑制糖尿病大鼠肾脏ICAM-1、VCAM-1表达(P<0.05),具有保护糖尿病大鼠肾脏的作用.

Influence of Rhubarb on Renal Expression of Intercellular Adhesion Molecule-1 and Vascular Cell Adhesion Molecule-1 in Diabetes Mellitus Rats

Objective To explore the influence of DaHuang on renal expression of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) in diabetes mellitus rats. Methods After the DM rat model was made, 24 DM rats were selected randomly and divided into a model group (12 DM rats) and a Rhubarb group group were given pure water in equal amount every day. 8 weeks later, kidney was cut to make pathological slice and method of SP immunohistochemistry was adopted for staining. Observed the expression of ICAM-1 and VCAM-1. Result The renal expression of ICAM-1 and VCAM-1 in the rhubarb group and the model group were obviously increased compared with the normal group (P<0.05). The renal expression of ICAM-1 and VCAM-1 in the rhubarb group was obviously weaker than the normal group(P<0.05). Conclusion Rhubarb could obviously inhibit the renal expression of ICAM-1 and VCAM-1 in diabetes mellitus rats and protect kidney of diabetes mellitus rats.
