OBJECTIVE Quantitative analysis of (99m)Tc-pertechnetate salivary gland scintigraphy has been used in the evaluation of salivary gland function, but so far no one method can be considered optimal for this task. In this study, a semiquantitative method providing 2 functional parameters for objective assessment of salivary gland function by scintillation camera imaging was tested. METHODS Twent...

The localization of dopamine stores and the expression and localization of dopamine (DAT) and vesicular monoamine transporters (VMAT) type-1 and -2 and of dopamine D1-like and D2-like receptor subtypes were investigated in rat submandibular, sublingual, and parotid salivary glands by HPLC with electrochemical detection, as well as immunochemical and immunohistochemical techniques. Male Wistar r...

Background: The cervical sympathetic trunk-submandibular gland (CST-SMG) axis plays an important role in inflammation. An immunoregulatory heptapeptide, submandibular gland peptide T (SGP-T), was isolated from submandibular glands, and several of its biological activities have been identified. Results: SGP-T reduced shockinduced hypotension and allergen-induced disruption of migrating myoelectr...

Changes in the expression of cytokeratin subunits during regeneration of the intralobular duct in partially injured rat submandibular glands were investigated. Limited parts of rat submandibular glands were injured by irradiation with YAG laser. Irradiated glands were investigated histologically and immunohistochemically using anti-cytokeratin monoclonal antibodies, RCK105 and CK19. Irradiated ...

Sialolithiasis is a condition characterized by the obstruction of a salivary gland or its excretory duct by calcareous concretions. It is a common disease of major salivary glands and mainly affects the submandibular gland. Bilateral submandibular sialolithiasis, however, is a rare condition. No systemic disorders, with the exception of gout, were found to be related to salivary stone formation...

The non-obese diabetic (NOD) mouse is chosen among other experimental models to study autoimmune sialadenitis resembling Sjögren's syndrome (SS), because of its unique characteristic of developing salivary dysfunction. Based on the deep loss of nitric oxide synthase (NOS) activity in parotid glands of NOD mice observed from early stages of disease and the inhibitory effect of nitric oxide (NO) ...

PURPOSE The aim of this study was to evaluate the changes in salivary gland function in patients with chronic renal failure (CRF) undergoing hemodialysis. METHODS The group consisted of 23 patients with CRF (13 female, 10 male; mean age: 40 +/- 13 yr) and 14 healthy control subjects (mean age: 40 +/- 13 yr). All underwent dynamic salivary gland scintigraphy with gustatory stimulation. After i...

Myoepithelial carcinomas are rare malignant tumors arising from salivary glands. They most commonly involve the parotid and minor salivary glands but may also occur in the submandibular glands. These tumors can become extensive, causing bony expansion and destruction. A 31-year-old man with a large swelling on the left side of the face is presented. Histologic examination of an incisional biops...

sialolithiasis is a common disease of the major salivary glands, characterized by the obstruction of a salivary gland or its excretory duct due to the formation of calcareous concretions. sialoliths usually measure from 1 mm to <10 mm. they rarely measure more than 15 mm, and infrequently giant salivary gland calculi >15 mm have been reported in the literature. the submandibular gland and its d...

Objectives To test the feasibility of submandibular salivary gland (SMG) replantation techniques and the survival of the replanted glands. Such a study can provide a rationale for later allotransplantation procedures, along with implementation of conventional and advanced immunosuppression therapy. Materials and Methods Six SMG replantations were performed in New Zealand white rabbits. One we...
