Abstract： 目的:探索姜黄素对炎症性肠病(IBD)模型大鼠肠黏膜炎症靶点基质金属蛋白酶(MMP)-9的影响.方法:建立以三硝基苯磺酸诱导的大鼠IBD模型.模型大鼠给予含20g/L姜黄素的饲料喂养,药物对照组给予含2 g/L N-乙酰半胱氨酸和5g/L柳氮磺胺吡啶的饲料喂养,模型组及正常对照组给予普通饲料喂养.评价肠炎大鼠死亡率及肠黏膜病理组织学评分.电泳迁移率改变分析法检测肠黏膜胞核NF-κB活性的变化.应用Western印迹分析法检测肠黏膜细胞质IκB.半定量RT-PCR检测MMP-9 mRNA的表达.结果:姜黄素可降低IBD模型大鼠死亡率及改善肠黏膜病理组织学症状.姜黄素可抑制IBD模型大鼠肠黏膜胞质IκB的降解并抑制胞核NF-κB的激活,同时降低MMP-9的表达.结论:姜黄素可预防和改善IBD鼠科模型中的实验性肠炎,调控MMP-9的表达;MMP-9可作为观察抗肠炎药物药效的指标之一,姜黄素对治疗IBD有应用前景.
