  • Title: Diffusion through the vessel wall of transmitter released by sympathetic stimulation. A fluorescence and Autoradiography study.
    Author: Dolezel S, Gerová M, Gero J, Feit J.
    Journal: Blood Vessels; 1975; 12(2):108-21. PubMed ID: 1139042.
    Abstract:
    The disposition of sympathetic transmitter within the wall of rat femoral and rabbit saphenous arteries has been studied during sympathetic stimulation. Using a histochemical fluorescence technique, sharply delineated bead-like fluorescent spots representing sympathetic nerve terminals were found at the adventitio-medial junction. In specimens excised during sympathetic nerve stimulation, the entire media was veiled by fluorescent material representing noradrenaline which had diffused into that layer after release. The localization of the nerve terminals in controls as well as diffusion of transmitter during stimulation in the rat femoral artery was corroborated by autoradiography of tritiated noradrenaline.
