摘要 目的探讨灯盏花素(Breviscapine,Bre)注射液对心肌缺血再灌注(Myocardial Ischemia and Reperfusion,MIR)大鼠血清肿瘤坏死因子(TNF-α)、白介素-6(IL-6)的影响。方法 40只SD大鼠随机分为假手术组(Sham组)、模型组、Bre组。Bre组于术前1周腹腔注射不同剂量的Bre(25,50 mg.kg-1.d-1),另2组给等量生理盐水。采用结扎大鼠左冠状动脉前降支方法制备MIR模型。缺血30 min、再灌注2 h后,观察大鼠心功能的变化;用HE染色在光学显微镜下观察心肌组织的病理改变;ELISA法检测各组大鼠血清中TNF‐α及IL-6水平。结果 Bre可以改变MIR损伤大鼠心电图T波变化幅度,减少MIR损伤导致的心律失常发生率;MIR组大鼠心肌细胞结构出现明显的病理改变;Bre能显著降低MIR后大鼠血清TNF‐α,IL-6的含量。结论灯盏花素能减轻TNF-α及IL-6对缺血再灌注大鼠心肌的损伤。
