The immunohistological localization of gammaA, secretory "piece" (SP), and lactoferrin (LF) in the mucosae of a variety of normal human tissues was investigated using specific fluoresceinated antisera. gammaA staining was localized in the apical portion of the mucosal epithelium, intercellular spaces, basement membrane area, and plasma cells of the interstitium or lamina propria of a number of ...

Patients with Sjögren's syndrome (SS) have characteristic lymphocytic infiltrates of the salivary glands. To determine whether the B cells accumulating in the salivary glands of SS patients represent a distinct population and to delineate their potential immunopathologic impact, individual B cells obtained from the parotid gland and from the peripheral blood were analyzed for immunoglobulin lig...

the sialolipoma is a rare neoplasm of salivary glands, described as a distinct entity by nagao et al . in 2001. thirty-six cases of sialolipoma in minor and major salivary glands have reported thus far in addition to reporting two new cases of osteolipoma arising in the major salivary gland in this study. thirty-six cases of sialolipoma that published in english language reports were analyzed i...

Patterns of salivary HCO secretion vary widely among species and among individual glands. In particular, virtually nothing is known about the molecular identity of the HCO transporters involved in human salivary secretion. We have therefore examined the distribution of several known members of the Na(+)-HCO cotransporter (NBC) family in the parotid and submandibular glands. By use of a combinat...

BACKGROUND Evidence in imaging studies suggests that there may be differences in glandular involvement in Sjogren's syndrome (SS) depending on the stage of the disease. No detailed histological studies are available to show if there are any such difference in glandular involvement at various time periods and stages of SS. This cross sectional study examines the inflammatory changes in mouse mod...

composed of cells that exhibit sebaceous differentiation; these tumors account for less than 0.1% of all salivary gland neoplasms (1, 2). The parotid gland is the most frequently involved of the salivary glands, where sebaceous differentiation is common (3). There is little information available in English literature on the radiologic features of this rare neoplasm, especially that of cystic se...

Chromatin template activity of mouse parotid glands increases after a single injection of isoproterenol (IPR), a procedure that causes, after a lag period of 20 hr, a marked stimulation of DNA synthesis and cell division in salivary glands of rodents. The increase in chromatin template activity occurs as early as 1 hr and peaks between 6 and 10 hr after IPR, paralleling previously reported chan...

Accessory parotid glands are a common clinical occurrence and usually drain into the main Stenson's duct by small ductules and thereby, into the buccal cavity. Presence of an accessory parotid gland with an ectopic fistulous duct is a rare occurrence. We present the imaging findings in a case of right accessory parotid gland with ectopic fistulous duct associated with bilateral pre-aural append...

The secreted carbonic anhydrases, CA VI, are high molecular mass, oligomeric enzymes originally found in the sheep parotid gland and saliva. The enzymes have been purified from the saliva or parotid glands of several different species. All the CA VI enzymes studied have an apparent subunit Mr of about 45,000 as previously reported for the sheep enzyme. By Western analysis, CA VI from human, cow...
