摘要:
目的:通过 DSS 诱导产生溃疡性结肠炎后,建立睡眠剥夺模型,并观察褪黑素、双歧杆菌对溃疡性结肠炎是否具有缓解作用;方法:通过将小鼠随机分为对照组,SD 处理组, DSS 处理组,DSS+SD 组,DSS+SD+ 益生菌组,DSS+SD+ 褪黑素组,对小鼠进行 7 天 DSS 诱导产生溃疡性结肠炎,再进行为期 10 天的睡眠剥夺,通过 DAI 评分,形态学检查与生化检查 如 ELISA,观察其细胞因子 IL-10 与 MPO 活性的变化,以判断褪黑素的疗效;结果:褪黑素的使用可使溃疡性结肠炎小鼠的体重明显回升(p< 0.05),粪便隐血症状明显改善(p<0.01), 且组织中 MPO 浓度与无治疗处理组的小鼠相比显著下降(p<0.01),IL-10 水平显著升高(p<0.01);结论:褪黑素可缓解溃疡性结肠炎小鼠的症状。Objective: To investigate the effect of Melatonin and bifidobacterium in relieving Ulcerative colitis(UC) induced by DSS and sleep deprivation.Methods: Sperate mice randomly into control (group), SD (group), DSS, DSS+SD, DSS+SD+ Probiotics, DSS+SD+ Melatonin, induce UC with above process in the first 7 days, and began sleep deprivation for 10 days. By DAI, morphological examination and ELISA, to investigate the differences of the expression of IL-10 and MPO.Results: Melatonin can significantly increased the weight of mice with ulcerative colitis (p< 0.05), significantly improved fecal occult blood symptoms (p<0.01), and significantly decreased MPO and increased il-10 levels in tissues compared with mice without treatment (p<0.01).Conclusions: Melatonin alleviated symptoms in mice with ulcerative colitis.
