“…Another phenomenon of pharmacological interest in which the neuronal uptake of catecholamines has been implicated is the development of supersensitivity to catecholamines in sympathetically denervated organs. It is now well established that a major factor underlying such denervation sensitivity is the loss of neuronal uptake sites which accompanies the degeneration of the terminal sympathetic innervation (Hertting, Suko, Widhalms & Harbich, 1967;Langer, Draskoczy & Trendelenburg, 1967).…”
