Abstract： 目的探讨肥大细胞(mast cell,MC)在重症急性胰腺炎(SAP)时的致病作用,了解肥大细胞膜稳定剂对SAP的治疗作用.方法将15只健康雄性SD大鼠随机分为3组:假手术组、SAP组及MC膜稳定剂处理组.MC膜稳定剂处理组应用MC膜稳定剂色甘酸钠,以50 mg/kg的用量于制模前30 min注入大鼠腹腔进行预处理.使用胆管注射5%牛磺胆酸钠法诱发SAP,观察各组大鼠血清淀粉酶、胰腺及肺组织病理变化、组织髓过氧化物酶(MPO)活性以及肺干湿重比的变化情况.结果SAP组的淀粉酶水平为2 500.0±227.7 U/L,胰腺髓过氧化物酶活性为0.41±0.01U/g湿重,肺干湿重比为4.58±0.29,胰腺病变评分为6.4±0.5,均较假手术组明显增高(P＜0.05).而使用MC膜稳定剂预处理后造模,其淀粉酶水平降为1 894.40±124.37 U/L,胰腺髓过氧化物酶活性为0.38±0.15 U/g湿重,肺干湿重比为4.35±0.13,胰腺病变评分为3.4±0.5,均较SAP组明显减轻(P＜0.05).结论肥大细胞可能在SAP发病过程中起着重要的作用,MC膜稳定剂对SAP可能有治疗作用.
