Journal ArticleDOI
TL;DR: The results indicate that dopamine is practically not taken up by neuronal or extraneuronal mechanisms, and differences observed among the effects of dopamine and noradrenaline are mostly due to differences on sensitivity towards neuronal uptake and to other minor factors.
Abstract: The contractile effects of dopamine and noradrenaline were compared in the rat isolated vas deferens, in order to obtain evidence for the presence or absence of postsynaptic dopamine receptors in this tissue. Attention was given to the role of several factors known to interfere with receptor characterization.
