Biphasic vasoconstriction of the rabbit ear artery.
Sympathetic nerve stimulation and intralummal norepinephrine infusion for more than 15 seconds produced a biphasic response in the isolated rabbit ear artery perfused with RREBS solution. This response consisted of an initial rapid constriction (phase A), which was followed by partial relaxation, and a final slowly developing constriction (phase B), which lasted for the duration of nerve stimul...

A contraction of the rabbit ear artery can be induced by depolarizing the cells with a K-rich solution if Ca is present. 10(-9)-10(-6) M noradrenaline and 10(-8)-10(-7) M histamine cause a contraction of this tissue without modifying the membrane potential. If the histamine concentration exceeds 10(-7) M some depolarization of the membrane also occurs. Both noradrenaline and histamine also indu...
