Introduction In humans, three pairs of major salivary glands and numerous minor salivary glands secrete saliva. Variety of pathological processes like inflammatory, infectious, obstructive, autoimmune, systemic and neoplastic disorders affects the salivary glands. Sialolithiasis is the second most common disease of the salivary glands after mumps. It is also the most common disease of submandib...

OBJECTIVE Uptake of 99mTc-pertechnetate in salivary glands reflects intact salivary gland parenchyma. However, no standardized protocol for an accurate quantification of parenchymal function has been established so far. METHODS In this paper we report on a validated acquisition protocol supplying a normal database for standardized quantitative salivary gland scintigraphy. RESULTS The major ...

The aim of this study was to investigate the radioprotective effect of thymol as a natural product against salivary glands dysfunction induced by ionizing radiation in rats. The rats were treated with thymol at dose of 50 mg/Kg before exposure to ionizing radiation at dose 15 Gy. Salivary gland function was evaluated with radioisotope scintigraphy and then salivary gland to background counts ra...

Saliva plays an essential role in maintaining oral health. Alterations in salivary function lead to compromise of oral tissues and functions and have a large impact on a patient’s quality of life. Reductions in salivary flow most commonly manifest as symptoms of oral dryness. This subjective complaint of dry mouth is termed xerostomia, whereas objective alterations in salivary performance, quan...

The secretory cells of the salivary glands of the snail, Helisoma trivolvis, exhibit regenerative, overshooting action potentials whose ampliture may exceed 100 mV. The salivary glands consist of paired, tubular, epithelial structures with acinar outpocketings. The secretory cells display extensive electrical coupling which allows action potentials to propagate along the glandular epithelium. S...

Introduction Tumors of salivary glands are very rare in children overall, and rarely in minor salivary glands. Among them pleoomorphic adenoma (PA) is the most common benign tumor of salivary glands in children and it acounts 60% of all salivary neoplasms, frequently found in major salivary glands (85 %) and rarely in minor salivary glands (10-15%). PA appears as painless oval mass, elastic con...

The salivary glands are divided into major and minor/accessory glands. Tumours are not rare in salivary glands and are mainly found in major salivary glands. Tumours of accessory salivary glands are relatively less common. Accessory parotid gland is a small unit of salivary gland tissue lying on the masseter muscle and seperated from the main parotid gland with an accessory duct draining into t...

Apoptosis in developing Drosophila embryos is rare and confined to specific groups of cells. We explain how one organ, salivary glands, of Drosophila embryos avoids apoptosis. senseless (sens), a Zn-finger transcription factor, is expressed in the salivary primordium and later in the differentiated salivary glands. The regulation of sens expression in the salivary placodes is more complex than ...

BACKGROUND Some species of the whitefly Bemisia tabaci complex cause tremendous losses to crops worldwide through feeding directly and virus transmission indirectly. The primary salivary glands of whiteflies are critical for their feeding and virus transmission. However, partly due to their tiny size, research on whitefly salivary glands is limited and our knowledge on these glands is scarce. ...
