Summary

By use of the “formaldehyde induced fluorescence” extramedullary chromaffin cells are demonstrated in the mediastinum and retroperitoneum of rats and guinea-pigs. Furthermore their vascularisation is studied by means of Indian ink-gelatin injections. It can be shown that the groups of these cells (1) have a rich vascularisation and (2) that single cells lie close to capillaries. Only occasionally adrenergic terminals are seen to supply these cells. Our findings are discussed in view of an endocrine or a storage function of these cells for catecholamines.

Zusammenfassung

Zur Darstellung der extramedullären chromaffinen Zellen (e. chr. Z.) im Mediastinum und Retroperitoneum von Ratten und Meerschweinchen wurde die „formaldehyde induced fluorescence“ verwendet. Außerdem wurden die diese Zellen versorgenden Gefäße mit Tusche-Gelatine sichtbar gemacht. Die e. chr. Zellgruppen sind reich kapillarisiert, die Zellen liegen den Gefäßen eng an. Die Versorgung der e. chr. Z. mit adrenergen Nerven ist spärlich. Diese Befunde sprechen für eine endokrine Funktion der Zellen oder für eine Katecholaminspeicherung.
