摘要(Abstract):
目的探寻活血解毒方关于糖尿病大鼠视网膜组织Notch信号通路的影响。方法将大鼠随机分为模型组、正常组、活血解毒方组。采用一次性腹腔注射链脲佐霉素65 mg/kg,建立糖尿病大鼠模型。灌胃12周后,取大鼠视网膜组织,应用免疫组化技术测定Notch1、Dll4的表达变化;提取大鼠视网膜组织中的总蛋白,应用Western-blot技术检测Hes1的表达变化。结果 1)免疫组化结果显示,模型组Notch1、Dll4表达量高于正常组(P<0.05),活血解毒方组Notch1、Dll4表达量低于模型组(P<0.05);2)Western-blot的结果显示,模型组Hes1表达高于正常组(P<0.05),活血解毒方组Hes1表达低于模型组。结论活血解毒方可能通过抑制糖尿病大鼠视网膜组织中的Notch信号通路,减少Notch1、Dll4、Hes1的表达,阻止糖尿病视网膜病变的恶化。
