OBJECTIVES Evaluation of Acoustic Radiation Force Impulse Imaging (ARFI) elastography performance in predicting the elasticity of the submandibular glands in normal situations and after radiation therapy. MATERIAL AND METHOD A number of 54 normal submandibular glands from 27 voluntary subjects and 33 pathological submandibular glands (radiation submaxillities) from 18 patients who had undergo...
OBJECTIVE In the current study, we examined whether selenium supplementation during iodine-131 (131I) treatment had a radio-protective effect on salivary glands. SUBJECTS AND METHODS Sixteen patients with differentiated thyroid cancer were prospectively enrolled in the study. Patients after total thyroidectomy, before 131I treatment, were divided into two groups; 8 patients in the selenium gr...
The objective of this work was to study the effect of the aerobic physical training and the cafeteria diet introduced after weaning of Wistar rats and on the morphology of the main salivary glands (parotid, submandibular, sublingual). Male rats after weaning were subjected to the cafeteria diet or the standard rodent chow, and either performed aerobic physical training in a treadmill for 100 da...
Objectives: The present study is to evaluate Virtual Touch Tissue Quantification (VTQ) technique in the prevention of submandibular gland damage in patients with Nasopharyngeal Carcinoma (NPC) after Intensity-Modulated Radiation Therapy (IMRT). Material and method: A total of 61 patients diagnosed with NPC were treated with IMRT. All the patients underwent Ultrasonography (US) while submandibul...
This study was designed to explore the protective effects of selenium on submandibular glands of rats that were maintained on liquid diet. The animals kept on liquid diet for 10 days following 20 days of solid diet, had severe degeneration on both acinar and ductal cells: pycnotic nuclei, enlarged granular endoplasmic reticulum, swollen mitochondria with separated cristae, reduction of secretor...
Myoepithelial cells (MECs) exist on the basal surface of acini in major exocrine glands, include myofilaments and various constructive proteins, and share characteristics with smooth muscle and epithelial cells. MECs project several ramified processes to invest acini, and possibly contract to compress acini to support the secretion by the glandular cells. However, the functional roles of MECs i...
Autologous submandibular gland transplantation is an effective treatment for severe dry eye syndrome. However, the protein secretion in transplanted gland is altered by a mechanism that remains to be elucidated. In the present study, we found that β1-adrenoceptor (β1-AR) and β2-AR expression and the phosphorylation of the downstream molecule protein kinase A (PKA) were elevated in transplanted ...
Stem cell-based regenerative therapy is a promising treatment for head and neck cancer patients that suffer from chronic dry mouth (xerostomia) due to salivary gland injury from radiation therapy. Current xerostomia therapies only provide temporary symptom relief, while permanent restoration of salivary function is not currently feasible. Here, we identified and characterized a stem cell popula...
To elucidate the localization of post-translational modifications of different classes of human salivary proteins and peptides (acidic and basic proline-rich proteins (PRPs), Histatins, Statherin, P-B peptide, and "S type" Cystatins) a comparative reversed phase HPLC-ESI-MS analysis on intact proteins of enriched granule preparations from parotid and submandibular glands as well as parotid, sub...
INTRODUCTION Immunoglobulin G4-related disease (IgG4-RD) is a newly recognized fibro-inflammatory condition. Forty-two cases with immunoglobulin G4-related sialadenitis (IgG4-RS) confirmed by histopathological and immunohistochemical assessment were studied to clarify the clinicopathologic characteristics of the salivary glands involved in IgG4-RS, especially the relationship between the histop...
