The paper concerns studying the participation of cyclic nucleotides in the mechanisms of action of cholecystokinin on gallbladder function in man. Cyclic nucleosides (cAMP and cGMP) were identified by radioimmunoassay in the duodenal contents obtained from men in response to intravenous injection of cholecystokinin. The data obtained suggest that the action of cholecystokinin on gallbladder function in man is mediated via cGMP, whereas cAMP is not implicated in the effect of of cholecystokinin on gallbladder function in man. Disturbances in cyclic nucleotide systems may be viewed in the light of the evidence obtained as a possible pathogenetic factor in the development of gallbladder dyskinesia.
