Efficacy of High Specific Volume Polysaccharide – A New Type of Dietary Fiber – On Molecular Mechanism of Intestinal Water Metabolism in Rats With Constipation

Background The aim of this study was to evaluate the effects of a new type of dietary fiber – high specific volume polysaccharide (HSVP) – on fecal properties, serum vasoactive intestinal peptide (VIP) concentration, intestinal flora count, and expression of the VIP-cAMP-PKA-AQP3 signaling pathway.
