Comment After administration of enalaprilate no changes in whole pancreatic blood flow could be observed. However, the islet blood flow was markedly increased, leading to an almost doubling of the fraction of whole pancreatic blood flow being diverted through the islets.

Glucose

in blood
Comment Enalaprilate affected neither basal nor glucose-stimulated insulin release, whereas angiotensin II delayed the first phase of insulin release in response to glucose. The effect of angiotensin II was probably due to initial marked vasoconstriction. The retardation of insulin release could be avoided by adding angiotensin II to the perfusion medium 20 min before glucose administration, i. e. so that the vasoconstriction had disappeared when glucose-stimulation began.
