概括
从母乳养的小猪中移植便微生物群 (FMT) 可以减少配方养 (FF) 小猪的腹. 通过增加Bifidobacterium和5-HIAA水平,FMT恢复了有益的肠道细菌并改善了肠道健康.
科学领域:
- 动物科学动物科学
- 微生物学 微生物学
- 胃肠病学 胃肠病学
背景情况:
- 配方料在猪生产中正在增加,这是由于母猪繁殖率的提高.
- 腹是配方养 (FF) 小猪的重要健康问题,影响动物福利和生产力.
- 便微生物群移植 (FMT) 在恢复肠道微生物群和治疗腹方面表现有前途.
研究的目的:
- 评估从母乳养的小猪中获得的FMT在缓解FF小猪腹方面的有效性.
- 调查FMT对FF小猪肠道微生物群组成,结肠形态和屏障功能的影响.
- 探索与FMT治疗效果相关的潜在机制,包括分子途径和代谢概况.
主要方法:
- 随机对照试验将小猪分配到对照,FF和FMT组.
- 评估腹发病率,结肠形态和肠道屏障功能.
- 对肠道微生物群组成的分析,重点关注细菌属的丰富性 (例如Bifidobacterium).
- 测量炎症标志物,JNK/MAPK通路激活,以及托代谢物 (5-HIAA) 的水平.
- 使用IPEC-J2细胞进行体外实验以验证5-HIAA的作用.
主要成果:
- 与对照组相比,FF猪仔表现出更高的腹率,受损的结肠形态和受损的屏障功能.
- FMT治疗使结肠形态和屏障功能正常化,抑制了JNK/MAPK通路,并减少了促炎细胞因子的产生.
- 在接受FMT治疗的小猪中,有益的Bifidobacterium的丰富性被恢复.
- 托芬代谢物5-HIAA和阿里尔碳化合物受体 (AHR) 敏感基因 (CYP1A1,CYP1B1) 在FMT后被上调.
- 综合的多组学分析显示,Bifidobacterium和5-HIAA之间存在强烈的正相关性.
- 在体外,5-HIAA补充剂减轻了脂聚糖 (LPS) 诱导的紧结和细胞因子生产的破坏.
结论:
- FMT有效地降低了腹的发生率,并改善了FF小猪的生长性能.
- FMT的治疗效果与Bifidobacterium的恢复和5-HIAA水平的增加有关.
- FMT调节肠道微生物群和宿主新陈代谢,为配方养小猪管理腹提供了一个有希望的策略.

Drugs for Treatment of Diarrhea-Predominant IBS
192
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Drugs Affecting GI Tract Motility: Opioids as Antidiarrheal Agents
221
Diarrhea, a condition marked by frequent loose or watery bowel movements, can be triggered by multiple factors such as viral or bacterial infections, food intolerances, anxiety, medications, and digestive disorders. Symptoms may include abdominal pain, bloating, nausea, and cramping. Severe or prolonged diarrhea can lead to complications like electrolyte imbalances, malnutrition, and dehydration if left untreated.
