Characterization of the alpha-1 adrenoceptors in the mesenteric vasculature from deoxycorticosterone-salt hypertensive rats: studies on vasoconstriction, radioligand binding and postreceptor events.


The vasoconstrictor responses to alpha-1 adrenoceptor agonists, binding behavior of alpha-1 adrenoceptors and postreceptor events in the mesenteric vasculature from deoxycorticosterone acetate-salt hypertensive rats were studied. The reactivity of perfused mesenteric artery to norepinephrine (NE) and phenylephrine, but not KCl, was enhanced significantly in… (More)
