the life cycle of the american trypanosome, trypanosoma rangeli, in its invertebrate host, rhodnius prolixus, is completed by invasion into the insect salivary glands. as a prerequisite, there is an initial recognition of the salivary gland receptors for the adhesion/invasion by t rangeli. therefore, the purpose of this study was to investigate the putative receptor molecules on either the sali...

objective: the aim of the present study was to investigate the demographic and pathological aspects of adenoid cystic carcinomas (acc) in an iranian sample based on a 20-year archive review. materials and methods: in this descriptive study, tumors of the head and neck registered between 1980 and 2000 were evaluated and cases of acc were selected. patients' medical records and pathology reports ...

epidermal growth factor (egf) is a polypeptide molecule, with important functions in epithelial growth and wound repair. it exerts its effects on cells by binding to receptors on the cell surface. the aim of this study was to evaluate and compare salivary egf levels in patients with gingivitis and advanced periodontitis as well as in healthy controls.unstimulated salivary samples were collected...

External irradiation of advanced head and neck cancer often includes the major salivary glands, despite them not being affected by the disease. The aim of this study was to determine neuron-specific enolase (NSE) as a marker of inflammation in irradiated and non-irradiated salivary glands of the rat. This study shows that NSE expression in irradiated salivary glands is dependent on the topograp...

cystadenoma is a rare benign salivary gland tumor that chiefly originates in the minor salivary glands as a cystic growth with papillary projections into the cystic lumen without the lymphoid element. it is further classified into two histopathological variants that have been recognized by world health organization as the papillary and the mucinous forms of cystadenoma. clinically, it is diffic...

Epithelial myoepithelial carcinoma is a rare biphasic low grade neoplasm of salivary glands; it most commonly occurs in the parotid gland but can also arise in minor salivary glands. Here a case of 58-year-old female presented with left cheek swelling of one-year duration. CT scan revealed a localized submandibular salivary gland tumor mass not involving surrounding tissues. Histological examin...

Salivary glands are important for secretion of saliva, which is essential for bolus formation, swallowing and maintaining a healthy oral cavity [1]. Salivary glands consist of acinar and duct cells. Injury to salivary glands, such as the damage that occurs following radiation treatment for head and neck cancer, causes a decrease in the number of acinar cells and the ability of the glands to pro...

Introduction: In this study the automatic separation of oral and salivary gland activity and spontaneous secretion by means of factor analysis for quantitative salivary gland scintigraphy is introduced. Methods: After intravenous administration of 99mTc sodium pertechnetate, dynamic scintigraphy was performed. 20 minutes after tracer application 2 ml of lemon juice was delivered to stimulate t...
