Effects of adrenaline and noradrenaline upon the smooth muscle contractile activity were shown to have a biphasic character. In low concentrations the effects coincide with that of phenylephrine, in high concentrations--with that of isadrine. The alpha-adrenoreceptors seem to be located at the metasympathetic neurons of the intramural ganglia and at postganglionic cholinergic nervous fibers, whereas the beta-adrenoreceptors at the smooth muscle cells.
已表明肾上腺素和去甲肾上腺素对平滑肌收缩活动的影响具有双相性。在低浓度时，其作用与去氧肾上腺素的作用一致；在高浓度时，与异丙肾上腺素的作用一致。α-肾上腺素能受体似乎位于壁内神经节的节后交感神经元和节后胆碱能神经纤维上，而β-肾上腺素能受体则位于平滑肌细胞上。
