Action of cholecystokinin and caerulein on the rabbit sphincter of Oddi. 1976

J C Sarles, and J M Bidart, and M A Devaux, and C Echinard, and A Castagnini

The action of cholecystokinin (CCK) and caerulein upon the rabbit sphincter of Oddi was investigated by electromyography, manometry and measuring of the flow. Intravenous injection of CCK resulted in a marked rise of the sphincter activity with a maximum at the 1st min and return to the basal level at the 10th min. Injection of increasing doses of hormone showed that the effect was proportional to the logarithm of the dose. The same results were obtained with caerulein. Parallely, CCK provoked a rise of the biliary pressure also proportional to the logarithm of the dose and a reduction to the biliary flow. The discrepancies between these results and some other experiments are discussed. It is concluded that, in the rabbit, CCK increases the activity of the sphincter of Oddi.

D011817	Rabbits	A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D002108	Ceruletide	A specific decapeptide obtained from the skin of Hila caerulea, an Australian amphibian. Caerulein is similar in action and composition to CHOLECYSTOKININ. It stimulates gastric, biliary, and pancreatic secretion; and certain smooth muscle. It is used in paralytic ileus and as diagnostic aid in pancreatic malfunction.

D002766	Cholecystokinin	A peptide, of about 33 amino acids, secreted by the upper INTESTINAL MUCOSA and also found in the central nervous system. It causes gallbladder contraction, release of pancreatic exocrine (or digestive) enzymes, and affects other gastrointestinal functions. Cholecystokinin may be the mediator of satiety.
