Abstract

Purpose. Crohn's disease (CD) and ulcerative colitis (UC), the two major forms of inflammatory bowel disease (IBD), have histopathologically and immunologically different characteristics. We previously reported that a traditional Japanese medicine, daikenchuto (TU-100), ameliorated a trinitrobenzenesulfonic acid- (TNBS-) induced type-1 model colitis exhibiting histopathological features of CD through adrenomedullin (ADM) enhancement. Our current aims were to examine whether TU-100 ameliorates a type-2 model colitis that histologically resembles UC and identify the active ingredients. Methods. TU-100 was administered orally to mice with oxazolone- (OXN-) induced type-2 model colitis. The morbidity was evaluated by body weight loss and the macroscopic score of colonic lesions. ADM was quantified using an EIA kit. Results. TU-100 prevented weight loss and colon ulceration. ADM production by intestinal epithelial cells was increased by TU-100 addition. Screening to identify active ingredients showed that [6]-shogaol and hydroxy α -sanshool enhanced ADM production. Conclusions. TU-100 exerted a protective effect in OXN-induced type-2 model colitis, indicating that TU-100 may be a beneficial agent for treatment of UC.

摘要

目的。克罗恩病(CD)和溃疡性结肠炎(UC)是两种主要的炎症性肠病(IBD),它们在组织病理学和免疫学上具有不同的特征。我们之前曾报道,一种传统的日本药物,大建中汤(TU-100)通过增强肾上腺髓质素(ADM),改善了一种表现出 CD 组织病理学特征的三硝基苯磺酸(TNBS)诱导的 1 型模型结肠炎。我们目前的目的是研究 TU-100 是否能改善类似于 UC 的组织学特征的 2 型模型结肠炎,并确定其有效成分。方法。将 TU-100 口服给予氧化偶氮甲烷(OXN)诱导的 2 型模型结肠炎小鼠。通过体重减轻和结肠病变的宏观评分来评估发病率。使用 EIA 试剂盒定量 ADM。结果。TU-100 可预防体重减轻和结肠溃疡。TU-100 的添加可增加肠上皮细胞 ADM 的产生。活性成分的筛选表明,[6]-姜烯和羟基 α -山椒素增强了 ADM 的产生。结论。TU-100 在 OXN 诱导的 2 型模型结肠炎中发挥了保护作用,表明 TU-100 可能是治疗 UC 的有益药物。
