The Journal of clinical investigation, 100(8), 2007-2014 (1997-10-23)
We explored in 51 normal subjects, distributed in various series of experiments, whether endothelium nitric oxide may play a role in insulin modulation of alpha2- and beta-adrenergic- evoked vascular responses. In particular, we examined the forearm blood flow response (FBF...

To characterize neonatal mesenteric alpha-adrenoceptor populations, an extracorporeal perfusion circuit was established to control intestinal blood flow in prematurely delivered (by cesarean section at 90% of gestational age) piglets. Activation of alpha 1-adrenoceptors was documented by observing dose-dependent increases in...

Sciatic nerve ligation in rats (chronic constriction injury (CCI)) induces clinical signs and symptoms that mimic human conditions of neuropathic origin, such as reflex sympathetic dystrophy (RSD). Denervation-induced supersensitivity to (circulating) catecholamines has been implicated in sympathetic dysfunction in the...

In rat aorta, the presence of functional alpha(2)-adrenoceptors (alpha(2)-AR) was investigated in ring preparations preconstricted with alpha(1)-adrenergic and non- alpha(1)-adrenergic agonists. Particularly, the hypothetical interference of alpha(2)-AR agonists with alpha(1)-AR-mediated vasoconstriction was evaluated. Relaxant and contractile responses to alpha(2)-AR agonists...

This study analysed the inhibition produced by the agonists moxonidine (imidazoline I(1) receptors>alpha(2)-adrenoceptors) and agmatine (endogenous ligand of imidazoline I(1)/I(2) receptors), using B-HT 933 (6-ethyl-5,6,7,8-tetrahydro-4H-oxazolo[4,5-d]azepin-2-amine dihydrochloride; alpha(2)-adrenoceptors) for comparison, on the rat cardioaccelerator sympathetic outflow. Male Wistar rats were pithed...
