摘要/Abstract

摘要： 目的: 探究选择性环氧合酶-2(COX-2)抑制剂是否加重佐剂性关节炎大鼠胃黏膜损伤及其机制。方法: 将32只雄性SD大鼠随机分为空白对照组、关节炎对照组、正常给药组和关节炎给药组,给予选择性COX-2抑制剂塞来昔布灌胃4周,取大鼠胃组织行HE染色损伤评分以及大体损伤评分。结果: 关节炎对照组、关节炎给药组大鼠胃黏膜损伤病理评分以及大体评分与空白对照组相比均增加;正常给药组大鼠胃黏膜损伤病理评分以及大体评分与空白对照组相比均无显著差异;关节炎用药组大鼠胃黏膜损伤病理评分以及大体评分与关节炎对照组相比均无显著差异。结论: 在治疗剂量下,塞来昔布不会造成正常大鼠胃黏膜损伤,也不会加重佐剂性关节炎大鼠胃黏膜的损伤;佐剂性关节炎大鼠存在胃黏膜损伤,这可能与关节炎所致全身慢性炎症有关。

Abstract: Objective: To investigate whether selective COX-2 inhibitors aggravate gastric mucosal injury and its mechanism in adjuvant induced arthritis rats. Methods: 32 male SD rats were randomly divided into blank control group, arthritis control group, normal administration group and arthritis administration group. They were given celecoxib, a selective COX-2 inhibitor, by gavage for 4 weeks. Then take the gastric tissue of rats for HE staining injury score and gross injury score. Results: The pathological score and gross score of gastric mucosal injury in arthritis control group and arthritis administration group were higher than those in blank control group; There was no significant difference in the pathological score and gross score of gastric mucosal injury between the normal administration group and the blank control group; There was no significant difference in the pathological score and gross score of gastric mucosal injury between the arthritis administration group and the arthritis control group. Conclusion: At the therapeutic dose, celecoxib, a selective COX-2 inhibitor, did not cause gastric mucosal damage in normal rats or aggravate gastric mucosal damage in adjuvant arthritis rats. There was gastric mucosal injury in adjuvant arthritis rats. Gastric mucosal injury in adjuvant arthritis rats may be related to the systemic chronic inflammation caused by arthritis.
