“…As regards the parotid gland of hamster, there are quite a few reports describing the fine structure of the parotid glands of Chinese, golden and European hamsters [11,14,22,24,25]. No attempt has ever been made, to our knowledge, by the light and transmission electron microscopic observations on the parotid gland of Djungarian hamster.…”

“…The acinar cells of the parotid gland were positive to PAS but were negative for AB staining, and the mandibular acinar cells were positive to PAS and were stained by AB. The parotid acini consisted of serous cells that are PAS-positive and AB-negative in Syrian hamsters [4], Chinese hamsters [14], mice [10], rats [10], and seromucous cells have a PAS-and ABpositive nature in Djungarian hamsters [11] and ginea pigs [3]. As for the mandibular gland in rodent species, there are several reports describing that the acinar cells are of a seromucous type with a PAS-and ABpositive nature [2,8,12,13,16].…”

Abstract:The parotid and mandibular glands of the cotton rat were examined by light and transmission electron microscopy. Parotid gland: Acinar cells were serous in nature, and contained electron-dense granules. Intercalated duct cells contained electron-dense granules. Striated duct cells had small granules of moderate and high electron densities. Mandibular gland: Acinar cells were seromucous in nature, and contained granules of low and moderate electron densities. Intercalated duct cells contained granules of moderate and high electron densities. Striated ducts were comprised of two portions -a secretory portion and a striated portion without granules. The secretory portion had many electrondense granules. A sexual dimorphism was obserbed in these granules, which were smaller and fewer in females than in males.

Secretion by striated ducts of mammalian major salivary glands: Review from an ultrastructural, functional, and evolutionary perspective

et al. 2001

In addition to their role in electrolyte homeostasis, striated ducts (SDs) in the major salivary glands of many mammalian species engage in secretion of organic products. This phenomenon usually is manifested as the presence of small serous-like secretory granules in the apical cytoplasm of SD cells. The composition of these granules is largely unknown, except in the case of the cat and rat submandibular gland, where the granules have unequivocally been shown to contain kallikrein. In some species, the apical cytoplasm of SD cells contains variable numbers of vesicles, both spherical and elongated, that vary in appearance from 'empty' to moderately dense. In the rat parotid gland, lucent vesicles transport glycoproteins to the luminal surface where they are incorporated into the apical plasmalemma and the glycocalyx. There is a strong possibility that in various species some of these vesicles are involved in transcytosis of antibodies to the saliva from their source (plasma cells) in the surrounding connective tissue. In addition, vesicles may engage in transfer of growth factors from the saliva to the interstitium. In a few species, conventional SDs have been replaced by ducts that are wholly given over to secretion, i.e., they entirely lack basal striations; although such ducts occupy the histological position of conventional SDs, it is not clear whether they represent a new type of duct or merely are modifications of SDs. Broad-based comparisons of ultrastructural and other data about SDs offer some insight into evolutionary history of salivary glands and their role in the adaptive radiation of mammals. Evolutionary patterns emerged when we made interspecific comparisons across mammalian orders. Among the bats, there is a clear relationship between SD secretion and general categories of diet.
