“…Additional variation between species has been described in granule ultrastructure of the respiratory glands in rat , pig (Turek et al, 1982), and human (Meyrick and Reid, 1970;Thaete et al, 1981). Much of the variability observed between species is emphasized in a recent volume on the comparative biology of the lung (Tyler et al, 1983).…”

This study was designed to characterize the ultrastructure and carbohydrate content of secretory cells in submucosal glands of rhesus monkey and to compare this information with that available for humans. The tracheas from five adult monkeys were fixed by airway infusion, processed, and embedded for both light and transmission electron microscopy. Histochemical strains including alcian blue-periodic acid-Schiff, dialyzed iron, and high-iron diamine-alcian blue were applied to serial glycol methacrylate sections. The cytochemical stains used included periodic acid-thiocarbohydrazide-silver proteinate, high-iron diamine, and low-iron diamine. The glandular secretory cells were divided into four categories based on ultrastructure and location within the gland. Cells in the first category resembled the mucous cell of the surface epithelium and were located in ducts most proximal to the tracheal lumen. The second category consisted of cells that were located in distal ducts and contained large electron-lucent granules. The granules in both of these cell groups contained material that was periodate-reactive and sulfated. Cells of the third category contained granules that were either electron-lucent or electron-dense. These cells, which were difficult to characterize as either serous or mucous, were located in secretory tubules and acini and contained periodate-reactive glycoconjugates that were either sulfated or nonsulfated. The last category consisted mainly of cells that contained electron-dense granules that were lightly periodate-reactive or a few that were unreactive with any of the cytochemical methods used here.(ABSTRACT TRUNCATED AT 250 WORDS)

The ultrastructure of the parotid gland was examined in the little brown bat. The seromucous acinar cells contained abundant granules of variable morphology. These granules were characterized by a submembranous dense layer consisting of fine parallel slats. In some bats, the matrix of the granules was structureless, whereas in others it consisted of closely packed but randomly arranged bundles of tubules. The intercalated ducts had a highly developed rough endoplasmic reticulum, often containing large numbers of intracisternal granules. In contrast, only a few secretory granules were present in the supranuclear cytoplasm. The striated ducts, which exhibited the characteristic basal striations consisting of vertically oriented mitochondria and highly folded plasmalemmas, contained numerous small dense granules in a subluminal band. These granules had a paracrystalline substructure with a periodicity of 8 nm. Excretory ducts strongly resembled striated ducts. They showed the same kind of basal striations and about half their constituent cells contained small paracrystalline granules.
