title: In vitro effects of ethanolamine on insulin secretion.
abstract: The effects of ethanolamine on insulin secretion by the perfused rat pancreas were examined. During the second phase of glucose-induced insulin secretion 5-minute perfusions of ethanolamine at final concentrations of 0.1, 1 and 10 mM inhibited insulin release in a dose-related manner. When given throughout the experiment the highest dose of ethanolamine markedly suppressed both phases of glucose-induced insulin release. The inhibitory effect of ethanolamine was blunted in the presence of phentolamine. It is concluded that ethanolamine inhibits glucose-induced insulin secretion by the perfused rat pancreas and that alpha-adrenergic receptors play a role in its actions on insulin output.
