摘要 目的:通过观察心肌缺血再灌注对缺血区心肌细胞表达 P物质( SP)和降钙素基因相关肽( CGRP)表达的影响,探讨吗啡预先给药在心肌缺血再灌注中的病理生理学的影响。方法:健康成年雄性SD大鼠24只,采用结扎左冠状动脉前降支的方法制备心肌缺血再灌注动物模型。结果:P物质:I/R组(5.14±0.39)缺血区心肌SP表达显著高于Sham组(3.27±0.36);与I/R组比较,M组(4.46±0.39)有低趋势,但无统计意义;降钙素基因相关肽:I/R组(543.47±26.85)缺血区心肌SP表达显著高于Sham组(346.06±19.42);与I/R组比较,M组(462.04±9.43)明显减低(P<0.05)。结论:吗啡预先给药可降低大鼠心肌缺血再灌注心肌组织SP、CGRP的表达。
