Similar sensitivities of pancreatic and biliary secretion to cholecystokinin plus secretin infusion. 1976

I L Macgregor, and J R Knill, and J H Meyer

The differing sensitivities of the gallbladder and pancreas to graded doses of CCK have been claimed as important in normal digestive events. As both secretin and CCK are thought to be released in response to normal feeding, we have reexamined the sensitivities of the gallbladder and pancreas to graded increases of CCK with a constant secretin background. Under such conditions the increase in output of pancreatic trypsin and bile salt occurred simultaneously, the dose-response curves being almost superimposable. Thus, under conditions more closely approaching normal postcibal events, the previously described differing sensitivities of the pancreas and gallbladder were not observed.

UI MeSH Term Description Entries
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010179 Pancreas A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
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. Pancreozymin,CCK-33,Cholecystokinin 33,Uropancreozymin
D005704 Gallbladder A storage reservoir for BILE secretion. Gallbladder allows the delivery of bile acids at a high concentration and in a controlled manner, via the CYSTIC DUCT to the DUODENUM, for degradation of dietary lipid. Gallbladders
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
D001647 Bile Acids and Salts Steroid acids and salts. The primary bile acids are derived from cholesterol in the liver and usually conjugated with glycine or taurine. The secondary bile acids are further modified by bacteria in the intestine. They play an important role in the digestion and absorption of fat. They have also been used pharmacologically, especially in the treatment of gallstones. Bile Acid,Bile Salt,Bile Salts,Bile Acids,Acid, Bile,Acids, Bile,Salt, Bile,Salts, Bile
D012633 Secretin A peptide hormone of about 27 amino acids from the duodenal mucosa that activates pancreatic secretion and lowers the blood sugar level. (USAN and the USP Dictionary of Drug Names, 1994, p597) Secrepan,Secretin Citrate, Pig,Secretin Maleate, Pig,Secretin Pentacetate, Pig,Secretin Sulfate, Pig,Secretin, Pig,Secretin-KABI,Pig Secretin,Pig Secretin Citrate,Pig Secretin Maleate,Pig Secretin Pentacetate,Pig Secretin Sulfate,Secretin KABI,SecretinKABI
D014357 Trypsin A serine endopeptidase that is formed from TRYPSINOGEN in the pancreas. It is converted into its active form by ENTEROPEPTIDASE in the small intestine. It catalyzes hydrolysis of the carboxyl group of either arginine or lysine. EC 3.4.21.4. Tripcellim,Trypure,beta-Trypsin,beta Trypsin
