[Some cytological aspects of the epithelium of the striated ducts in the human parotid and submaxillary glands].

Some cytological features peculiar to striated ducts epithelium of normal parotid and submaxillary glands were investigated by transmission electron microscopy. Interspersed among the clear cells, which comprise the great majority, dark cells have been encountered. Large lipoid bodies with histochemical reactions typical of lipofuscins were also observed. In three case only, polysome-lamella complexes consisting of concentric lamellar cylinders alternating with layers of polysomes were noted. This study indicates that some ultrastructural features, previously attributed to inflammatory diseases, may also occur in normal salivary glands.
