Cytochemical Studies on Gll. vestibulares nasi of Cat

Abstract

The cat Gli. vestibulares nasi were investigated cytochemically. The changes caused by the subcutaneous injection of pilocarpine were observed. The presence of beaded mitochondria in glandular cells is ascertained, but their contour is not distinct. The terminal extension stains dark with iron hematoxylin.
The pilocarpine in jection results in a decrease of the basophilia. Presumably glycogen does not exist in the glandular cell, or its amount is extremely small, if it is present. No remarkable changes is observed after the injection.
An intense alkaline phosphatase activity is seen in the the luminal side of the cytoplasm. The injection results in a general intensification of the activity, and a remarkable intensification is found in the myoepithelium.
An intense acid phosphatase activity is observed in the nucleus of the glandular cell. The injection causes a general intensification of the activity, and an espeCially intense activity is demonstrated in the luminal side of the cytoplasum.
