The Golgi Apparatus and Secretion of Enzymes in Peptic Cells of Rabbit

Abstract

In rabbits starved for 48 hr. with free access to water, the Golgi apparatus as shown by the Aoyama technique, as modified by me, is in the form of a compact reticulum lying close to the luminal pole of the nucleus (Fig. 1.1). After feeding, the Golgi reticulum expands and increases gradually in volume until it occupies the luminal part of the cytoplasm (Fig. 1.2–4). During increased secretory activity, the power of the Golgi substance to reduce silver nitrate or osmium tetroxide gradually increases; this suggests that besides the morphological changes, chemical changes occur in the Golgi substance. In the fed rabbits, argentophile secretory granules appear in the field of the Golgi apparatus, and as the latter hypertrophies the secretory granules increase in number (Fig. 1.2–3).
