“The ability of yohimbine or prazosin , at alpha 2- and alpha 1-adrenoceptor specific concentrations respectively, to antagonize the effects of BHT 933 suggests a lack of agonist specificity for these receptor effect as previously suggested for the mesenteric artery.”
“Yohimbine (300 nM) or prazosin (28 nM) at alpha 2- and alpha 1-adrenoceptor specific concentrations respectively, blocked this inhibition of renin release by BHT 933.”
