Abstract
Addition of conjugated bile salts increased transmural- and transserosal-potential, differences of sheets of rat jejunum. Removal of Cl− from buffer solutions minimized the bilesalt induced bioelectric changes. Bile-salt induced doubling of tissue resistance was not explained by an observed increase in net Cl− serosa → mucosa flux. Electrical effects were unrelated to concentration and were observed only when bile-salt solutions perfused the jejunal mucosa. The molecular events associated with bile-salt interactions with the plasma membrane affecting ion fluxes may relate to their unique effects on sterol absorption.
