Dopamine receptors in pancreatic acinar cells from dog.

Dispersed acini from dog pancreas were used to characterize dopamine receptors in a study on the stimulation of cellular cyclic AMP formation and the binding of [3H]dopamine. Dopamine elicited concentration-dependent stimulation of cellular cyclic AMP with a maximal increase occurring at a concentration of 0.1 mM (EC50 = 1 microM).

Long-term comparative effect of cholecystokinin and gastrin on mouse stomach, antrum, intestine, and exocrine pancreas.

Mice were injected three times a day for 12 days with 300 micrograms/kg body weight of gastrin G17 or 37.5 Ivy dog U/kg body weight of CCK or saline. Other mice were also injected four times an hr for 1 hr with 7.
