Interaction of systemic and local vascular regulation of the intestinal circulation during systemic infusion of norepinephrine

AUTHORS' SYNOPSIS

In these studies escape of the intestinal vasculature from the constrictor effect of norepinephrine was examined during systemic intravenous infusion of this catecholamine. Under these conditions about 60% of the escape response appeared to be due to local pressure independent adjustments, 20% due to local pressure dependent adjustments, and 20% due to systemic neurogenic adjustments.
