Influence of dopamine as noradrenaline precursor on the secretory function of the bovine corpus luteum in vitro.

abstract：:1. Caerulein displayed a potent stimulant action on pancreatic secretion in the dog. Threshold doses were 1-5 ng/kg by rapid intravenous injection, 0.25-1 ng/kg per min by intravenous infusion and 50-100 ng/kg by subcutaneous injection. There was a conspicuous increase not only in the volume flow of pancreatic juice b...
