Dietary calcium decreases but short-chain fructo-oligosaccharides increase colonic permeability in rats [PDF]
, 2010 An increased intestinal permeability is associated with several diseases. Nutrition can influence gut permeability. Previously, we showed that dietary Ca decreases whereas dietary short-chain fructo-oligosaccharides (scFOS) increase intestinal ...

Effect of permeability enhancers on paracellular permeability of acyclovir
Journal of Pharmacy and Pharmacology, 2016 AbstractObjectivesAccording to Biopharmaceutics Classification System (BCS), acyclovir is a class III (high solubility, low permeability) compound, and it is transported through paracellular route by passive diffusion. The aim of this study was to investigate the effect of various pharmaceutical excipients on the intestinal permeability of acyclovir ...
