We studied the mechanisms of transformation some salivary enzymes and established real contribution glands to enzymatic homeostasis body in unilateral nephrectomy.The results were obtained that with nephrectomy, content amylase pepsinogen blood increases, but its lipolytic activity remains unchanged, volume basal secretion glands, release by parotid gland increases. Unilateral nephrectomy stimu...

Introduction: Radical radiation therapy of head and neck cancers may injure the salivary glands and reduce their function. Single-photon emission computed tomography (SPECT) images maybe used to evaluate function post-therapy. However, accurate quantification is hindered by the partial volume effects (PVEs). The present study involved the introduction of a PVEs quantif...

BACKGROUND Dysgenetic polycystic salivary gland disease is a rare pathology. No case of minor salivary gland involvement has been reported in the literature. METHODS A female patient presented with bilateral tumors of the parotid glands, bilateral submandibular gland enlargement, and multiple cystic lesions of the oral mucosa. MRI of the neck was performed along with fine-needle aspiration (F...

The molecular and pharmacological characteristics of muscarinic receptor subtypes in the rat parotid acinar cell line, PAR-C5, were determined and compared with native rat parotid glands to evaluate the PAR-C5 cell line as a model to study receptor-mediated secretion. Reverse transcription-polymerase chain reaction (RT-PCR) identified mRNAs for M(3), M(4), and M(5) receptor subtypes in both PAR...

It has been demonstrated that parotid glands of rats infected with Trypanosoma cruzi present severe histological alterations; changes include reduction in density and volume of the acini and duct systems and an increase in connective tissue. We evaluated the association between morphological changes in parotid glands, circulating testosterone levels and epidermal growth factor receptor (EGF-R) ...

The sparing of the parotid glands in the treatment of head and neck cancers is of clinical relevance as high doses to the salivary glands may result in xerostomia. Xerostomia is a major cause of decreased quality of life for head and neck patients. This paper explores the relationship between the overlap of the target volumes and their expansions with the parotid glands for helical delivery pla...

BACKGROUND The most common histological diagnosis of bilateral parotid gland neoplasm is Warthin tumor. Bilateral malignant tumors of the parotid gland are extremely rare. METHODS A 60-year-old man presented with a painless mass in the right preauricular area and an MRI scan showed multiple masses in the parotid glands, bilaterally. A standard superficial parotidectomy was performed on the ri...

Fukami, Hideyuki and Robert M. Bradley. Biophysical and morphological properties of parasympathetic neurons controling the paratid and von Ebner salivary glands in rats. J Neurophysiol 93: 678–686, 2005; doi:10.1152/jn.00277.2004. The inferior salivatory nucleus (ISN) contains parasympathetic neurons controlling the parotid and von Ebner salivary glands. To characterize the neurophysiological a...

Many patients with head and neck cancers receive radiation therapy as part of their treatment which frequently causes considerable morbidity, including various degrees of permanent salivary gland dysfunction. Three-dimensional treatment planning [3-DTP] and conformational dose delivery constitute a new therapeutic modality that conforms the high-dose radiation volume to the shape of the tumor v...

1. The liberation of ammonia from adenosine 5'-phosphate (AMP) and adenosine and the release of inorganic phosphate from AMP were investigated in homogenates of bovine and human parotid glands. 2. Adenosine phosphate deaminase (AMP deaminase) was purified from bovine and human parotid glands. The enzyme preparations obtained were free from adenosine deaminase and 5'-nucleotidase activities. 3. ...
