Gatecholamine Content and Response to Norepinephrine of Middle Cerebral Artery 1

Summary The norepinephrine (NE) and epinephrine (E) contents of bovine middle cerebral (MCA) and lingual (LA) arteries were determined fluorometrically. Although the amount of E was almost identical in the 2 vessels, the MCA contained almost four times as much NE as the LA. Cumulative NE dose-response curves revealed a much greater reactivity of the LA than the MCA. An inverse relationship is demonstrated between NE content and vascular reactivity to this agent, and a similar relationship is suggested between NE content and the degree of functional innervation in some vascular beds.
