亚科科技股份带领大家探讨下香芹酚(499-75-2)预处理对心肌缺血再灌注时线粒体损伤的作用:
【摘 要】: 目的 探索香芹酚(CAR)对心肌缺血再灌注(I-R)时线粒体损伤的作用.方法 C57 BL/6小鼠冠状动脉左前降支结扎45 min,解除结扎2h构建心肌I-R损伤模型.将小鼠随机分为3组(每组n=12):假手术组、Vehicle (DMSO in saline)+ I-R组、CAR(60 mg/kg)+ I-R组.Vehicle或CAR于冠脉结扎前15 min给药.心肌缺血45 min再灌注2h后,检测心肌梗死面积,并测定平均线粒体面积、线粒体分裂百分比、线粒体基质微粒及脂滴数量以评估线粒体损伤情况.结果 与假手术组相比,Vehicle组心梗面积显著增加,差异有统计学意义(P<0.05);与Vehicle组相比,CAR(60 mg/kg)预处理可显著减少心梗面积,差异有统计学意义(P<0.05).与Vehicle组相比,CAR预处理可显著降低平均线粒体面积、线粒体基质微粒数、线粒体周围脂滴数和线粒体分裂百分比,差异均有统计学意义(P<0.05).结论 CAR可通过减轻心脏组织中线粒体损伤降低小鼠心肌I-R后心梗面积.
