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 Drosophila salivary gland is proving to be an excellent experimental system for understanding how cells commit to specific developmental programs and, once committed, how cells implement such decisions. Through genetic studies, the factors that determine where salivary glands will form, the number of cells committed to a salivary gland fate, and the distinction between the two major cell ty...

Naphthyl esterase and platelet-activating factor (PAF)-acetylhydrolase activities were detected in the salivary glands of the cat flea, Ctenocephalides felis. Salivary naphthyl esterase activity is disgorged during exploratory probing. Whole extracts of salivary glands contain esterase activity against the short-chain naphthyl esters alpha-naphthyl acetate (approximately 210pmol/min/gland pair;...

abstract salivary gland tumors are among the pathologies in the head and neck that may be challenging in diagnosis and treatment. most benign tumors occur in the parotid gland. pleomorphic adenoma is the most common type. basal cell adenoma is a subtype of the monomorphic adenoma with rare occurrence. proper diagnosis and clinical evaluation by the use of radiography can lead the physician to t...

Introduction: High-dose radioactive iodine therapy in differentiated thyroid cancer (DTC) may adversely affect the salivary gland function. This study is aimed to evaluate the effect of radioactive iodine (RAI) with dose of 100 mCi in DTC patients compared to lower doses of less than 30 mCi in hyperthyroid cases. Methods: Fifty four patients (13 men and 41 women) age: 42.3±14.3 (21-71) years we...

The western chinch bug, Blissus occiduus Barber, is a serious pest of buffalograss, Buchloe dactyloides (Nuttall) due to physical and chemical damage caused during the feeding process. Although previous work has investigated the feeding behaviors of chinch bugs in the Blissus complex, no study to date has explored salivary gland morphology and the associated salivary complex of this insect. Who...

INTRODUCTION Cyfra 21 is a serum-soluble fragment of cytokeratin19. Increased Cyfra 21 serum levels and their benefit as a tumor marker have been shown in some malignancies. This study aimed to evaluate the serum levels of Cyfra 21 in patients with benign and malignant salivary gland tumors. MATERIALS AND METHODS In this cross-sectional study, the serum level of Cyfra 21 in 44 patients with m...

The effect of salivary gland extract of the stable fly, Stomoxys calcitrans (L), on bovine lymphocyte proliferation was determined, and antibody reactivity to salivary gland proteins was characterized in cattle exposed to stable flies. Salivary glands were dissected from male and female flies (4-8 d after eclosion), and protein extracts were made by freeze-thaw cycles. Salivary gland extract (S...

Gross morphological study was conducted on the major salivary glands of 42 buffalo foetuses ranging from 73 to 253 days. The mandibular gland was the largest salivary gland during the prenatal life. Dense compact lobulation of the parotid and mandibular glands was observed first at 155 days of foetal age. The mandibular gland was covered by the confluence of linguo-facial, occipital and maxilla...

Salivary gland cancers are uncommon malignancies of the head and neck region. Their site of origin can be major (parotid, submandibular and sublingual) or minor salivary gland (palate, nasal cavity, paranasal sinuses, trachea and lacrimal gland). Of all the salivary gland neoplasms, 85% are benign and 15% are malignant. Salivary gland malignancies comprise 3-6% of all head and neck cancers (Pin...
