Peripheral adrenergic receptors in hypertension.

Peripheral adrenergic receptors in hypertension.

Increased sympathoadrenal activity appears to play an important role in the development or maintenance of elevated blood pressure in hypertensive patients and various animal models of hypertension. Alterations of adrenergic receptor number or responsiveness might contribute to this increased activity. We therefore reviewed the data on adrenergic receptor alterations in hypertension with special...

Sex differences in peripheral vascular adrenergic receptors.

Although the incidence of many vascular diseases differs in men and women, sex differences in vascular physiology have not been extensively examined in human in vivo studies. The present study compared finger blood flow responses of normal men and women with brachial artery infusions of adrenergic agonists and with other neurally and nonneurally mediated procedures. In response to phenylephrine...

Renal a2-Adrenergic Receptors and Hypertension

I N 1964 Oj-adrenergic receptors were first described pharmacologically using the in vitro melanocyte granule dispersion technique in Rana pipiens. The goal of these studies was to assess the intrinsic activity on o^-adrenergic receptors of methyldopa's neurotransmitter metabolites and other catecholamines. Publication of this description was delayed for 13 years, 1 until the evidence for a rec...
