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 کاملINFLUENCE OF ENDO THELIUM REMOVAL AND LNAME ON RESPONSES OF RAT COMMON CAROTID ARTERY TO α-ADRENOCEPTOR AGONISTS
In this study we investigated the effects of endothelium removal and L-NAME on responses to α-adrenoceptor agonists. Male Wistar rats were killed by overdose with pentobarbitone sodium, after which the left and right common carotid arteries were removed. Rings of arteries 3-4 mm in length were cut from each vessel and then mounted in 10 mL isolated organ bath, bathed in Krebs maintained at ...

متن کاملPRE- AND POSTJUNCTIONAL α-ADRENOCEPTORS IN RABBIT ARTICULAR BLOOD VESSELS
Previous in vitro work on rabbit knee joint vessels showed that vasoconstrictor effects of nerve stimulation and administration of α-adrenoceptor agonists were mediated predominantly by α1-adrenoceptors5,9 The present experiments were performed to assess the nature of α-adrenoceptor subtypes within these blood vessels in vivo. Dose/response relationships for adrenaline and noradrenaline pr...
