A novel model of adenine-induced chronic kidney disease-associated gastrointestinal dysfunction in mice: The gut-kidney axis.

Although constipation is a common complication of chronic kidney disease (CKD), there is no animal model that can be used to study the association between renal impairment and gastrointestinal function without interfering with the gastrointestinal tract of the model. Therefore, we determined whether adenine could induce CKD in association with gastrointestinal dysfunction. Six-week-old ICR mice were intraperitoneally injected with saline, 25, 50, or 75 mg adenine/kg body weight for 21 days.

Amelioration of gut dysbiosis and gastrointestinal motility by konjac oligo-glucomannan on loperamide-induced constipation in mice.

Objective: Konjac oligo-glucomannan (KOG) is a non-digestible dietary fiber that is resistant to digestion and absorption in gastrointestinal (GI) tract. Thus, it might be used as an alternative management for constipation. The aim of this study was to evaluate the effects of KOG on gut motility and microbiota to relieve constipation in mice.

Prebiotic oligosaccharides from dragon fruits alter gut motility in mice.

Dragon fruit oligosaccharide (DFO) has a prebiotic property which improves gut health by selectively stimulating the colonic microbiota. Altering microbiota composition may affect intestinal motility. However, no study has been done to understand the DFO effects on gut motor functions.
