    Description / Table of Contents: Zusammenfassung Bei der normalen weißen Ratte verhält sich die Zona externa des Infundibulum im Gegensatz zur Zona interna infundibuli„gomorinegativ“. Am 7. Tag nach beidseitiger Adrenalektomie treten in der Zona externa „gomoripositive“ Substanzen auf, deren Menge über den 14. Tag nach der Operation hinaus zunimmt. Im supraoptico-hypophysären System ergibt die quantitative Messung eine Entleerung des neurosekretorischen Materials am 3. Tage nach beidseitiger Adrenalektomie. Im Verlauf von 14 Tagen nach dem operativen Eingriff füllt sich das neurosekretorische System wieder bis zu den beim Normaltier ermittelten Werten auf. Die „gomoripositiven“ Granula in der Zona externa inf. sind möglicherweise das morphologische Äquivalent eines Corticotropin-releasing factors.
    Notes: Summary In the normal albino rat, the external layer of the median eminence shows a “Gomori-negative” histochemical reaction as opposed to the internal layer. On the 7th day after bilateral adrenalectomy, “Gomori-positive” substances appear in the external layer, their amount increasing up to and beyond the 14th day p.o. In the supraoptico-hypophyseal system, quantitative measurements show a depletion of the neurosecretory substance on the 3rd day following bilateral adrenalectomy. This loss of neurosecretory material is restored during the course of 14 days p.o., the amount then corresponding to that found in the normal rat. It is conceivable that the “Gomori-positive” granules in the outer layer of the median eminence are the morphological equivalent of a CRF.
