[Effect of pancreastatin on pancreatic exocrine secretion in vivo and in vitro]. 1989

K Miyasaka, and R Nakamura, and A Funakoshi, and K Kitani

The effects of pancreastatin on pancreatic exocrine secretion were examined both in vivo and in vitro in rats. Pancreastatin inhibited pancreatic fluid and protein outputs stimulated by the exclusion of pancreatic juice from the intestine with the intraduodenal infusion of Trasylol but did not inhibit bicarbonate output stimulated by HCl in vivo in conscious rats. However, pancreastatin did not affect amylase release from dispersed acini or Ca concentration in acinar cells. Therefore, it is concluded that pancreastatin inhibits pancreatic exocrine secretion but the effect is indirect.

UI MeSH Term Description Entries
D008297 Male Males
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.
D010187 Pancreatic Hormones Peptide hormones secreted into the blood by cells in the ISLETS OF LANGERHANS of the pancreas. The alpha cells secrete glucagon; the beta cells secrete insulin; the delta cells secrete somatostatin; and the PP cells secrete pancreatic polypeptide. Hormones, Pancreatic
D011506 Proteins Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D053379 Chromogranin A A type of chromogranin which was first isolated from CHROMAFFIN CELLS of the ADRENAL MEDULLA but is also found in other tissues and in many species including human, bovine, rat, mouse, and others. It is an acidic protein with 431 to 445 amino acid residues. It contains fragments that inhibit vasoconstriction or release of hormones and neurotransmitter, while other fragments exert antimicrobial actions.
