[An electron microscopic study of the acinar cells of the submaxillary salivary glands of white rats].
Numerous rows of rough endoplasmic reticulum, large Golgi apparatus with condensation vacuoles and other ultrastructures typical for secreting cells of the exocrine type (secretory granules, smooth and covered vesicles, lysosomes, microtubules, mitochondria) were found in glandular acinar cells of the submaxillary salivary glands of albino rats. The substantial features of the given object are: firstly, low electron density of the content of the secretory granules which seems to be connected with high content of polysaccharides in the secretion and secondly, the presence of special inclusions covered with a typical three-layer membrane. The latter together with the rest of the content of the granules may come into the lumen of the central duct of the acinus and intercellular secretory capillaries.
