Tissue distribution of epidermal growth-factor (EGF) in rat was investigated using a human EGF (hEGF) radioimmunoassay system. Antisera generated against hEGF reacted with hEGF and [21Leu] hEGF but not with mouse EGF, fibroblast growth factor (FGF), nerve growth factor (NGF), platelet derived growth factor (PDGF), and endothelial cell growth supplement (ECGS). Similar amounts of EGF immunoreact...

In atrophic parotid glands induced by liquid diet, acinar cell apoptosis is increased while proliferative activity is reduced. This study aimed to clarify how liquid diet affects submandibular and sublingual glands, including acinar cell apoptosis and proliferation. Seven-week-old male Wistar rats were fed either a liquid (experimental group) or pellet diet (control group) from 3 to 21 days, re...

A 48-year-old man who had a complaint of swelling in the left submandibular region and right side of the neck was referred to our radiology clinic for sonographic examination that revealed a type 1 hydatid cyst with a diameter of 32 mm in the left submandibular gland, and a type 3 hydatid cyst with a diameter of 33 mm in the right thyroid gland. The diagnosis was verified by computed tomography...

Background Radiation-induced xerostomia is a distressing clinical condition that starts appearing from the initial stages of radiotherapy in head and neck cancer patients. Though submandibular glands contribute to maximum of the "resting salivary" secretions, most of the acute xerostomia experiments so far reported have been on animal parotid glands. Therefore, we assessed and quantified the hi...

The arterial vasculature in the floor region of the mouth and the submandibular region of the crab-eating monkey was studied by the acrylic plastic injection method. 1. The titled regions were found to be supplied by the hyoid branch and the sublingual artery arising from the lingual artery, and the submandibular glandular branch, the mylohyoid branch and the submental artery from the facial ar...

Sharing the airway is a major concern for both anaesthetist and surgeon because the security of the airway may be jeopardized and the tracheal tube might impede the surgical field. This is seen typically in maxillofacial and ENTsurgeries. Nasal intubation is widely exercised by anaesthetists in maxillofacial surgery but difficulties arise with panfacial fractures when an unobstructed surgical f...

Three cases of carcinosarcoma of the salivary gland, two in the submandibular gland, and one in the parotid, were investigated with CT and exhibited a variety of findings. The density of the tumors was lower than that of normal submandibular tissue. A calcification was found in one case. One case showed extensive lymphadenopathy. The parotid lesion had low central density with an enhancing margin.

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...

Objetivo: el objetivo de este estudio es recopilar la información más relevante en literatura con respecto a etiología, diagnóstico y tratamiento sialoadenitis submandibular crónica. Material métodos: utilizando los buscadores PubMed ScienceDirect se descargaron total 143 artículos referentes al tema, cuales sólo incluyeron 20 para realización estudio. Resultados: sialolitiasis principal causa ...

Dermoid cyst of the oral floor is rare benign tumour, who having three histological aspects: dermoid, teratoid and epidermoid. This one characterized by presence a squamous stratified epithelium with cutaneous remnants. It may occur in any part body, however their frequency ENT sphere relatively scarce. Seven per cent (7%) only epidermoid cysts cervico-facial area, 1.6% which locate at level. W...
