title: Effect of somatostatin on the potentiating action of glucagon, cyclic adenosine monophosphate and theophylline on glucose-induced insulin release.
abstract: The effect of glucagon on the inhibition of the insulin response to glucose induced by somatostatin was investigated in humans and in the isolated perfused rat pancreas. Both in vivo and in vitro somatostatin suppressed glucose-induced insulin release. This inhibitory effect of somatostatin was overcome by glucagon. Similar results have been observed in vitro by the infusion of theophylline or cyclic adenosine monophosphate.
