摘要 目的:研究急性心肌梗死(acute myocardial infraction,AMI)大鼠血浆Ghrelin水平变化,探讨人与大鼠Ghrelin在AMI病理过程中的潜在的生物学效应。方法:结扎左冠状动脉前降支制作AMI大鼠模型,实验设为正常对照组、假手术组、AMI模型组、AMI模型+人Ghrelin组及AMI模型+生长激素促分泌素(growth hormone secretagogues,GHSs)受体(GHSR)阻滞剂[D-Lys3]-GHRP-6组;以酶联免疫吸附试验(Enzyme-linked immunosorbent assay,ELISA)检测AMI术后24h大鼠血浆Ghrelin含量。结果:与正常组大鼠比较,大鼠血浆的Ghrelin水平均升高,但假手术组与正常组比较没有统计学意义;以GHSR阻滞剂组最高(P<0.01),人Ghrelin干预组比模型组低(P<0.05)。结论:MI术后24h大鼠Ghrelin明显升高,人Ghrelin抑制但GHSR阻滞剂增加AMI大鼠血液循环Ghrelin水平的升高,本研究结果有助于更好理解GHSR介导的心脏保护活性。
