We have succeeded in demonstrating for the first time adrenergic innervation in the Eustachian tube of guinea pigs. The approach was histochemical using the fluorescence method with glyoxylic acid. There was an apparent regional variation with a greater number of axon terminals in the pharyngeal area of the Eustachian tube as compared to the tympanic area.

Adrenergische Innervation der Ohrtrompete des Meerschweinchens


Zum ersten Mal wird die adrenergische Innervation der Ohrtrompete beim Meerschweinchen mittels histochemischer Untersuchung (Fluoreszenz-Methode) nachgewiesen. Dabei zeigt der pharyngeale Abschnitt der Tube eine größere Innervationsdichte als der tympanale.
