...D.A.S. Parker; I.S. de la Lande; J.A. Thompson; I. Parker The spontaneous and stimulation-induced (SI) effluxes of 3 H-norepinephrine ( 3 H-NE) and its metabolites from the intimal and adventitial surfaces of perfused segments of rabbit ear arteries were determined; vessels were previously...

...Michel F. Roberts; John D. Chilgren; Andrew C. Zygmunt We have studied contractile responses to norepinephrine (NE) and K + of isolated rabbit ear arteries and veins in an effort to determine how α -adrenoceptor affinity and smooth muscle contractility affect responsiveness at different...

... of rabbit ear artery, we have demonstrated that it is possible to selectively activate nerves, without stimulating smooth muscle directly. Adrenergic nerve activation was blocked with guanethidine, phentolamine or tetrodotoxin, while responses to direct smooth muscle activation persist in the presence...

...Ralph E. Purdy; Diana E. Hurlbut; Leslie A. Rains The effects of N, N’-bis-(O-methoxybenzylaminohexyl)-cystamine tetrahydrochloride (BHC), 2-brom-d-lysergic acid diethylamide (BOL) and prazosin on 5-hydroxytryptamine (5-HT) dose-response curves in rabbit ear artery and thoracic aorta were...

Watanabe The contractile effect of propranolol in isolated rabbit ear artery was assessed in reserpinized and in surgically and chemically denervated blood vessels. Reserpinization and surgical...

...Ivan S. de la Lande A number of factors which have been implicated in the response of the rabbit ear artery to adrenergic agents and stimuli are reviewed. Aspects discussed include: (a) the method of propagation of vasoconstriction in the arterial smooth muscle; (b) the interrelationship between...

...R.J. Head; R.E. Stitzel; I.S. de la Lande; S.M. Johnson When assayed on homogenates of the rabbit ear artery up to 192 h after sympathetic denervation, the activity of monoamine oxidase (MAO) showed a small but significant decrease (maximum 9%). The activity of catechol-O-methyl transferase (COMT...

...Stephen M. Johnson; Ivan S. de la Lande An inhibitor of extraneuronal uptake, deoxycorticosterone acetate (DOCA), increased the sensitivities of the rabbit ear artery to extraluminal and to intraluminal epinephrine, each approximately threefold. The effect on extraluminal epinephrine was increased...
