Vascular and Brain Dopamine β-Hydroxylase Activity in Young Spontaneously Hypertensive Rats

Abstract
Dopamine beta-hydroxylase activity was higher in mesenteric vessels, adrenal glands, and serum of 3-week-old spontaneously hypertensive rats but lower in the locus coeruleus than it was in the control Wistar-Kyoto rats. The results support the concept that the nervous system is an important regulator of blood pressure.
