【摘要】：目的觀察低聚果糖(FOS)對小鼠腸道黏膜的影響,并探討其對結腸炎的治療作用及可能機制。方法用5%DSS誘導建立小鼠結腸炎模型,將30例小鼠隨機分成正常組、模型組、FOS組。FOS組在模型建立后飲用配置好的5%FOS溶液。觀察各組疾病活動指數(shù)(DAI),實驗結束后觀察結腸長度變化、組織學損傷評分、菌群計數(shù)統(tǒng)計以及IL-6、IL-33、TNF-α、RegⅢγ的表達。結果 FOS組DAI(P0.000 1)及組織學損傷評分(P0.000 1)明顯低于模型組,模型組小鼠結腸質地變硬且黏膜皺褶消失(P0.01),FOS組結腸致病菌與模型組相比顯著減少(P0.01),FOS組結腸IL-6(P0.05)、IL-33(P0.05)的表達量相比于模型組顯著降低,TNF-α(P0.05)、RegⅢγ(P0.05)雖有降低但無統(tǒng)計學意義。結論低聚果糖能夠改善結腸炎小鼠有益菌群的比例,降低促炎細胞因子IL-33及IL-6的水平,減輕腸道炎癥反應。
[Abstract]:Objective to observe the effect of fructooligosaccharide (FOS) on intestinal mucosa in mice and to explore the therapeutic effect and possible mechanism of FOS on colitis. Methods the colitis model of mice was induced by 5 DSS. 30 mice were randomly divided into normal group and FOS group. The FOS group drank the 5 FOS solution after the model was established.
