Abstract:Solutions of varying chemical and osmotic composition were perfused through isolated upper or lower bowel loops in unanesthetized dogs. Enterosorption and absorption of solute ions were measured separately and an apparent insorption rate of solutes was estimated. The latter increased nearly linearly with log perfusate concentration. The slope constants (Δ insorption/Δ log conc.) differed among ions and differed for a given substance when certain other ions were present. Insorption rates at a standard solute co… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
