CONTRACTIONS DUE TO α-ADRENOCEPTOR AGONISTS ARE MEDIATED BY α1-ADRENOCEPTORS IN RAT CAROTID ARTERY
Some large vessels have a mixed functional population of postjunctional α1- and α 2-adrenoceptors. The purpose of the work presented here was to investigate the population of postjunctional α -adrenoceptors in the rat isolated common carotid artelY Male Wi star rats were killed by overdose with pentobarbitone sodium, after which the left and right common carotid arteries were removed. Rings...

متن کاملEndothelial modulation of contractions caused by oxyhemoglobin and NG-nitro-L-arginine in isolated dog and monkey cerebral arteries.
BACKGROUND AND PURPOSE Oxyhemoglobin is a key substance in provoking cerebral vasospasm and a scavenger of nitric oxide. The present study was designed to determine whether suppression of the action of endothelium-derived nitric oxide is involved in oxyhemoglobin-induced cerebroarterial contraction. METHODS Dog and monkey cerebral artery strips with and without endothelium were immersed for i...
متن کاملPotent P2Y6 receptor mediated contractions in human cerebral arteries
BACKGROUND Extracellular nucleotides play an important role in the regulation of vascular tone and may be involved in cerebral vasospasm after subarachnoidal haemorrhage. This study was designed to characterise the contractile P2 receptors in endothelium-denuded human cerebral and omental arteries. The isometric tension of isolated vessel segments was recorded in vitro. P2 receptor mRNA express...
متن کاملFunctional role of α1-adrenoceptor subtypes in murine ophthalmic arteries.
PURPOSE To identify the α(1)-adrenoceptor (α(1)-AR) subtypes mediating vascular adrenergic responses in murine ophthalmic arteries. METHODS Expression of mRNA was quantified for individual α(1)-AR subtypes in murine ophthalmic arteries using real-time PCR. To assess the functional relevance of α(1)-ARs for mediating vascular responses, ophthalmic arteries from mice deficient in one of the thr...
