Hamster nasal glands: their structure, @entity3167 content, and vulnerability to XXXX .

This study examines the structure of mucosal glands in the walls of the hamster maxillary recess, compares the histochemical appearance of nasal glands to their @entity3167 content, and determines the vulnerability of nasal glands to @entity4316 @entity137 . Observations were made on plastic-embedded tissue with light and transmission electron microscopes. Determinations of total @entity3167 in mucosal samples were conducted with @entity4466 . Experimental hamsters were administered 0.2 micrograms of @entity4316 (IP)/gm body weight/day for five days. Types of granules present in the later nasal gland (LNG) and glands of the maxillary recess (MRGs) include: 2.0 micrometers lightly basophilic, lightly electron-dense granules and 1.5 micrometers strongly basophilic, electron-dense granules in the same acinar cell type in both the LNG and MRGs; 1.5 micrometers metachromatic granules in some acinar cells of the LNG; 1.0 micrometer moderately electron-dense granules in cells of @entity5755 ducts; and 0.7 micrometers electron-dense granules in cells of LNG intercalated ducts. Acid glycoproteins, demonstrable by histochemistry, are present in the LNG but not in the MRGs. However, the total @entity3167 content of tissues from @entity5755 tissue is greater than that of other tissues measured. A minor number of LNG acini, those with metachromatic granules, have branching basal cytoplasmic projections. Many dark cells are present in striated ducts of the LNG. Histological alteration due to @entity4316 @entity137 , conspicuous in parotid salivary parenchyma, is greater in @entity5755 than in LNG tissue.
