Classification of postjunctional beta adrenoceptors mediating relaxation of canine bronchi.
Abstract
Adrenoceptors mediating relaxant responses to exogenously added or endogenously released catecholamines in isolated canine bronchi (3rd-6th order) were characterized using selective beta receptor agonists and antagonists. Norepinephrine (3 x 10(7) to 3 x 10(-5) M) or isoproterenol (3 x 10(-8) to 10(-6) M) fully relaxed tissues precontracted with 3 x 10(-7) M carbachol (Cch). Salbutamol (Sal) also relaxed Cch-precontracted tissues, but this …
