1鞘内注射吗啡预处理激活大鼠δ、κ、μ受体致心肌保护显示文摘背景鞘内注射小剂量吗啡可产生与静脉注射吗啡相似的心肌保护作用,但鞘内注射吗啡预处理(IT—MPC)与缺血预处理(IPC)作用强度的差别还未知,IT-MPC是否由阿片类受体所介导也未阐明。因此,本实验比较IT—MPC与IPC作用强度差别并探讨阿片类受体的作用。方法80只SD大鼠麻醉后开胸,成功置入鞘内导管后随机分为13组(n=6—7)。IPC组接受3次5分钟缺血-5分钟再灌注的心肌IPC(阻闭左冠状动脉),随之给予30分钟缺血-2小时再灌注诱导心肌缺血再灌注(IR)损伤。IT-MPC组按剂量不同分为4个亚组(分别是0.03、0.3、3及30μg/kg),以3次5分钟注射-5分钟间停的模式平均注入鞘内,随之诱导IR损伤。静脉注射吗啡预处理组(IV-MPC)组经静脉给予吗啡300μg/kg,对照组鞘内给予10μl生理盐水。受体阻滞剂组选择在IT—MPC(3μg/kg)前分别给予选择性δ、κ、μ受体阻滞剂NTD、nor-BNI及CTOP,以评价阿片类受体亚型的作用。通过2,3,5-tripheny ltetrazolium染色,计算心肌梗死面积(IS),即梗死心肌占缺血危险区(AAR)的百分比。结果与对照组相比,鞘内注射0.3~30μg/kg吗啡降低心肌IS,3组IS/AAR分别为33%±10%(0.3μg/kg)、29%±10%(3μg/kg)、29%±16%(30μg/kg),对照组为53%±8%(P〈0.01)。IT-MPC降低心肌IS/AAR程度与IV-MPC(33%±6%,P=0.84)及IPC(22%±4%,P=0.41)相近。注射选择性受体阻滞剂后,由IT-MPC(3μg/kg)产生的心肌预处理效果降低(NTD+IT-MPC,50%±9%:nor-BNI+IT-MPc,43%±6%;CTOP+IT—MPC,53%±9%;与对照组相比,P=0.14)。结论IT—MPC产生与IPC及IV—MPC相近的心肌保护作用,其机制涉及到δ、κ、μ受体。Rui Li Gordon T.
