Mucoepidermoid carcinoma (MEC) is a malignant neoplasms of the salivary glands which is rarely found in childhood. Its incidence rate has been reported to be 0.44 per 100,000.1 Most of them arise from the parotid gland (64 – 80%) while other locations that are less frequent include submandibular gland, sublingual gland, minor salivary glands and lacrimal gland.2 Submandibular gland cancer is ex...

GABA is an inhibitory transmitter found in rat salivary gland. However, the inhibitory potential of GABA on salivary secretion is unclear. Using an in vivo cannulation method, intraperitoneal administration of GABA was ineffective in the absence of gabaculine, a GABA transaminase inhibitor, on pilocarpine-induced salivary secretion, suggesting that GABA was rendered metabolically inactive befor...

Histological studies have demonstrated sensory nerve endings in the salivary glands of mammals. SASYBIN1) observed Krause's and Pacinian corpuscles in the connective tissue of the salivary gland. BAUMANN" found sensory endings in the wall of the small excretory duct of the salivary gland, and SUZUKI" also reported encapsulated sensory end-organs, such as Vater-Pacini corpuscles, in the acino-du...

Pleomorphic adenoma is the most common benign tumour of major salivary gland presenting as a painless mass gradually increasing in size, usually involving parotid gland. In minor gland, it more palate. lip rare tumour. Thus, we present case pleomorphic originating from upper 75 years old male patient. The tumor was completely excised and sent for histopathological examination which showed micro...

SM1 is a twelve-amino-acid peptide that binds tightly to the Anopheles salivary gland and inhibits its invasion by Plasmodium sporozoites. By use of UV-crosslinking experiments between the peptide and its salivary gland target protein, we have identified the Anopheles salivary protein, saglin, as the receptor for SM1. Furthermore, by use of an anti-SM1 antibody, we have determined that the pept...

Salivary gland cancers comprise a small subset of human malignancies, and are classified into multiple subtypes that exhibit diverse histology, molecular biology and clinical presentation. Local disease is potentially curable with surgery, which may be combined with adjuvant radiotherapy. However, metastatic or unresectable tumors rarely respond to chemotherapy and carry a poorer prognosis. Rec...

Cystadenoma and cystadenocarcinoma are rare salivary gland tumours histologically characterized by prominent cystic and frequently papillary growth. We present two cases of cystadenoma of a minor salivary gland (upper lip) and parotid cystadenocarcinoma respectively, captured between 834 salivary gland tumors studied in our hospital from 1980 to 2004. The authors review the clinical, histologic...

Saliva is a useful biofluid for the early detection of disease, but how distal tumors communicate with the oral cavity and create disease-specific salivary biomarkers remains unclear. Using an in vitro breast cancer model, we demonstrated that breast cancer-derived exosome-like microvesicles are capable of interacting with salivary gland cells, altering the composition of their secreted exosome...

The major salivary glands consist of the parotid, the submandibular, and the sublingual glands. Under the control of the parasympathetic nervous system, the major salivary glands are responsible for the principal portion of saliva produced, which can be as much as 1.5 liters per day. The minor salivary glands of the oral cavity, pharynx, and upper airways contribute only a small percentage of t...

Head and neck cancer patients treated by radiation commonly suffer from a devastating side effect known as dry-mouth syndrome, which results from the irreversible loss of salivary gland function via mechanisms that are not completely understood. In this study, we used a mouse model of radiation-induced salivary hypofunction to investigate the outcomes of DNA damage in the head and neck region. ...
