Effects of bromocriptine on pancreatic secretion in the isolated, blood-perfused pancreas of the dog. 1984

K Iwatsuki, and F Iijima, and S Chiba

Effects of bromocriptine on the secretion of pancreatic juice were investigated with dog isolated, blood-perfused pancreas. Bromocriptine (1-10 mg) caused dose-dependent increases in the secretion of pancreatic juice. However, bromocriptine did not affect the perfusion blood flow rate. The secretory response to bromocriptine was inhibited by pretreatment with a dopamine antagonist, sulpiride, but not by phentolamine, propranolol, atropine, metiamide, indomethacin or tetrodotoxin. Bromocriptine caused a dopamine-like secretion of the pancreatic juice containing a high concentration of bicarbonate but had little effect on protein output. These results suggest that bromocriptine increases pancreatic secretion stimulating directly on pancreatic dopamine receptors.

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.

D004285	Dogs	The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)	Canis familiaris,Dog
D004298	Dopamine	One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.
