SUMMARY The ability of foetal rat salivary epithelium, particularly from the parotid gland, to develop morphogenetically and functionally (amylase activity) in various mesenchymes, and the quantitative effects of altering mesenchymal mass on the development of the parotid epithelium, have been studied in vitro. Both parotid and submandibular epithelial rudiments were able to undergo morphogenes...

PURPOSE To present the clinical features of patients with parotid gland metastasis, and compare the results with previously published series. Most of the relevant literature arises from case reports, while there are only few series reported, as secondary neoplastic lesions of the parotid gland are uncommon. METHODS The medical records of patients with parotid gland metastasis, treated at the ...

Nicotine has been reported to increase the intracellular Ca concentration ([Ca]i) in sublingual acini due to neurotransmitter release from nerve terminals associated with the cell preparation (1). However, it is unclear whether or not the same reaction exists in parotid cells. Therefore, we investigated effect of nicotine on Ca mobilization in digested parotid acini from rats. After removing th...

BACKGROUND although several reports indicate that qualitative and quantitative assessments of parotid salivary function are age-stable in healthy adults, there have been no studies of the influence of age on the variability of repeated parotid flow rates. OBJECTIVE to examine the influence of age on the variability of repeated parotid flow rates in unmedicated, healthy adults. MATERIALS AND...

Human papillomavirus (HPV) infection has been shown to be associated with human tumorigenesis. The aim of the present study was to demonstrate the association between HPV infection and parotid gland tumors. Paraffin-embedded tissue sections from 59 cases of parotid gland tumors and 20 normal oral mucosa were subjected to DNA extraction and flow-through hybridization and gene chip technology to ...

conclusions a complete immunohistochemical study should be considered in cases of malignant salivary gland tumors. to reduce the recurrence rate of these tumors, the optimum therapies are radiotherapy and chemotherapy. introduction salivary gland tumors are rare head and neck lesions. the majority are benign, with only 20% of cases malignant. an epithelial-myoepithelial carcinoma is a rare low-...

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...

by increasing number of vessels. salivary gland tumors are uncommon and their overall incidence is about 3 per 100000 per year. salivary gland hemangioma makes up 1 % of all salivary gland tumors. trismus resulting from parotid hemangioma is so rare. the patient was a 6-month-old boy with a huge lesion in his right parotid who referred to shahid sadoughi hospital of yazd, iran. the lesion appea...

Introduction: Parotid glands contain adipose cells in the alveolar connective tissue and sebaceous glands that release lipid-secretary sebum [1]. The effect of parotid fat on parotid ADC measurement has been unavoidably neglected by the single-shot spin-echo echoplanar diffusion-weighted imaging (EP-DWI), which is essentially equipped by fat-saturation to eliminate chemical shift artifact. Unde...
