摘要 目的探讨还原性谷胱甘肽(GSH)消耗与胰腺炎严重程度的关系。方法 36只雄性Wistar大鼠随机分为两组:正常对照组(n=18)开腹后仅翻动胰腺即关腹;重症急性胰腺炎(SAP)组(n=18)以0.1 mL/min的速度向胰胆管内逆行注入4.5%牛磺胆酸钠(1 mL/kg)建立大鼠SAP模型,两组分别于造模术后3、6、12 h麻醉后,获取新鲜胰腺组织,各组每时点6只,取一部分用于GSH检测,另一部分用于病理学观察和电镜观察。结果 (1)SAP组各时点胰腺组织中GSH水平均明显比正常对照组低,差异均有统计学意义(P<0.05)。(2)胰腺组织病理学观察:SAP组出现急性坏死性胰腺炎病变,随着时间推移逐渐加重。病理学评分:各时点SAP组均较正常对照组高,差异均有统计学意义(P<0.01)。(3)电镜观察:随着时间推移,SAP组GSH消耗增加,粗面内质网结构紊乱,线粒体肿胀,甚至消失,腺泡细胞腔内囊泡排出明显减少。结论 GSH的消耗将导致细胞骨架直接暴露于氧自由基的攻击之下,正常的胰腺腺泡细胞骨架结构破坏,促进胰腺炎的发生、发展。
