虎杖苷對(duì)DSS和TNBS誘導(dǎo)的急性結(jié)腸炎的作用及機(jī)制的研究摘要：

目的：探討虎杖苷對(duì)DSS和TNBS誘導(dǎo)的急性結(jié)腸炎的作用及其機(jī)制。

方法：將40只小鼠隨機(jī)分為四組：正常組、模型組、虎杖苷高劑量組和虎杖苷低劑量組。模型組使用DSS和TNBS誘導(dǎo)急性結(jié)腸炎，虎杖苷高、低劑量組同時(shí)給予虎杖苷治療。采用病理學(xué)方法和ELISA檢測(cè)末段恢復(fù)期各組大鼠結(jié)腸組織病理學(xué)改變情況和白細(xì)胞介素-6（IL-6）、腫瘤壞死因子-α（TNF-α）等炎性因子水平。

結(jié)果：與模型組相比，虎杖苷低、高劑量組大鼠結(jié)腸組織病理學(xué)表現(xiàn)顯著改善，炎性細(xì)胞浸潤(rùn)明顯減少，并且虎杖苷高劑量組大鼠結(jié)腸組織病理學(xué)表現(xiàn)更佳。同時(shí)虎杖苷高、低劑量組IL-6、TNF-α水平明顯下降，其中虎杖苷高劑量組下降更明顯。

結(jié)論：虎杖苷具有顯著的治療DSS和TNBS誘導(dǎo)急性結(jié)腸炎作用，可能通過抑制炎性因子水平改善結(jié)腸組織病理學(xué)表現(xiàn)。

Introduction

急性結(jié)腸炎是一種以大腸為主要發(fā)病部位的腸黏膜炎癥性疾病，主要表現(xiàn)為腹痛、腹瀉、便血等癥狀。雖然目前已有多種藥物治療急性結(jié)腸炎，但是治療效果具有一定局限性。近年來(lái)，有研究發(fā)現(xiàn)中藥虎杖苷具有一定的抗炎作用，但其對(duì)急性結(jié)腸炎的作用和機(jī)制尚不明確。

Methods

40只BALB/C小鼠隨機(jī)分為正常組、模型組、虎杖苷高劑量組和虎杖苷低劑量組。模型組使用DSS和TNBS給予大鼠誘導(dǎo)急性結(jié)腸炎，虎杖苷高、低劑量組給予虎杖苷治療。采用病理學(xué)方法和ELISA檢測(cè)末段恢復(fù)期各組大鼠結(jié)腸組織病理學(xué)改變情況和IL-6、TNF-α等炎性因子水平。

Results

與模型組相比，虎杖苷低、高劑量組大鼠結(jié)腸組織病理學(xué)表現(xiàn)顯著改善，炎性細(xì)胞浸潤(rùn)明顯減少，并且虎杖苷高劑量組大鼠結(jié)腸組織病理學(xué)表現(xiàn)更佳。同時(shí)虎杖苷高、低劑量組IL-6、TNF-α水平明顯下降，其中虎杖苷高劑量組下降更明顯。

Conclusion

虎杖苷具有顯著的治療DSS和TNBS誘導(dǎo)急性結(jié)腸炎作用，可能通過抑制炎性因子水平改善結(jié)腸組織病理學(xué)表現(xiàn)。上述結(jié)果提示，虎杖苷可能成為治療急性結(jié)腸炎的潛在治療藥物。
