Summary.
In experiments on white rats it has been observed that the addition of potassium to solutions of glucose and sodium chloride causes a decrease of the glucose and the sodium net‐absorption in the distal part of the small intestine, but not in the colon. The effect is supposed to be caused by an unspecific effect on the mucosa.
Summary.
Previously it was found that the chloride as well as the sodium ions could be absorbed against a concentration gradient in the colon and the distal part of the small intestine of rats when pure sodium chloride solutions were infused. In this paper it is demonstrated that the chloride ion is still absorbed against a concentration gradient in the colon when sodium is replaced by potassium, calcium, magnesium or ammonium, and that sodium, too, is absorbed against a concentration gradient in the colon as well as the distal part of the small intestine when the chloride ion is replaced by acetate, nitrate, bicarbonate or sulphate ions.
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.
