Summary
A study was carried out on adrenergic innervation of the white adipose tissue by means of theFalck andOwman fluorescence method. The presence of abundant perivascular plexuses, which could be followed up to the level of the vascular capillaries, was demonstrated. The nerve fibers run like “puttees” around the capillaries. The adrenergic nerve fibers establish close contacts with the surface of the fat cells. The fat cells in the immediate vicinity of the vessels are provided for by the perivascular nerve fibers. In the adipose lobules adrenergic networks showing large meshes were observed. The adrenergic nerve fibers show also close contacts with the mast cells. Mast cells may be found both in the meshes of the perivascular plexuses and along the fibers supplying the fat cells.
Zusammenfassung
Die adrenergische Innervation des weißen Fettgewebes wurde mit Hilfe der Fluoreszenzmethode vonFalck undOwman untersucht. Die Anwesenheit zahlreicher perivaskulärer Geflechte, die bis um die vaskulären Kapillaren verfolgt werden konnten, wurde nachgewiesen. Weiter wurde festgestellt, daß die adrenergischen Nervenfasern auch in enger Verbindung zu der Oberfläche der Fettzellen stehen. Die in der nächsten Nähe der Gefäße gelegenen Fettzellen werden von den perivaskulären Nervenfasern innerviert. In den Fettläppchen kommen desgleichen auch großmaschige adrenergische Plexus vor. Enge Kontakte zwischen adrenergischen Nervenfasern und Mastzellen wurden beobachtet. Die Mastzellen liegen sowohl in den Maschen der perivaskulären Plexus, wie auch entlang der für die Fettzellen bestimmten Fasern.
