Keyword:  油橄榄叶提取物海洛因美沙酮消化酶十二指肠;
Abstract: 目的:探讨油橄榄叶提取物(olive leaf extract,OLE)联合美沙酮对海洛因依赖大鼠胃肠道消化酶活性及十二指肠组织结构的影响.方法:将40只健康大鼠随机分成正常组、模型组、美沙酮组、OLE+美沙酮组.按递增法采用皮下注射海洛因建立海洛因依赖大鼠模型,造模后药物处理30 d,用比色法检测血清脂肪酶(LPS)、淀粉酶(AMS)和胰蛋白酶(TRS)活性,用生物显微技术观察十二指肠组织结构的变化.结果:与正常组相比,模型组海洛因依赖大鼠血清LPS、AMS、TRS活性显著降低,十二指肠粘膜上皮掉落、溶解,隐窝空泡化甚至消失;与模型组相比,OLE+美沙酮组和美沙酮组大鼠血清LPS、AMS、TRS活性明显升高,十二指肠组织病理损害程度明显减轻.OLE联合美沙酮对海洛因依赖大鼠消化功能的治疗效果比美沙酮组更明显.结论:OLE和美沙酮联合治疗海洛因造成的胃肠道损害疗效优于单一的用药,两药合用具有很好的协同作用.
