introduction: natural killer (nk) cells, of which cd56 is a specific marker, play an important role in host defense against tumors. cancer stem cells, of which aldehyde dehydrogenase isoform 1 (aldh1) is an immunohistochemical marker, are a group of tumorigenic cells which are involved in migration and tumor recurrences. we aimed to evaluate the expression of aldh1 and cd56 in common salivary g...

Salivary gland cancers are uncommon malignancies of the head and neck region. Their site of origin can be major (parotid, submandibular and sublingual) or minor salivary gland (palate, nasal cavity, paranasal sinuses, trachea and lacrimal gland). Of all the salivary gland neoplasms, 85% are benign and 15% are malignant. Salivary gland malignancies comprise 3-6% of all head and neck cancers (Pin...

This study was designed to compare labial and sublingual salivary gland biopsies in the diagnosis of Sjögren's syndrome (SS). Fourteen labial and 29 sublingual specimens were considered positive. There was a better correlation between infiltration of the ductal structure and the focus score in the sublingual salivary gland biopsy than in the labial salivary gland biopsy. Use of sublingual saliv...

adenoid cystic carcinoma is an uncommon, slow growing malignant salivary gland tumor that is characterized by wide local infiltration, perineural spread, propensity to local recurrence anddistant metastasis. in this paper, the authors present a case of adenoid cystic carcinoma affecting the palate and involving the maxillary sinus in a 60‑year‑old male patient along with a brief reviewof litera...

Unlike cancers of related exocrine tissues such as the mammary and prostate gland, diagnosis and treatment of aggressive salivary gland malignancies have not markedly advanced in decades. Effective clinical management of malignant salivary gland cancers is undercut by our limited knowledge concerning the key molecular signals that underpin the etiopathogenesis of this rare and heterogeneous hea...

background: rhipicephalus ( boophilus ) annulatus tick is one of the most important ectoparasite of cattle. re­cently, several laboratories in the world have been concentrated on immunizing cattle against tick using various types of tissue extracts of ticks. the aim of this study was to evaluate the effect of immunization of cattle with tick salivary gland extract on biological parameters of ti...

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...

Salivary glands are exocrine that secrete saliva, which plays an important role in the maintenance of oral health. Few reports exist on contralateral salivary gland is not directly affected when one by sialolithiasis, radiation therapy, or a tumor. In present study, we investigated changes submandibular mice following excision unilateral gland. Outcomes this study showed and sublingual resectio...

Significant increase in the salivary gland weight was observed after exposure to single therapeutic dose of 3.7 MBq of 131I in mice. Pre-supplementation of antioxidants, O. sanctum leaf extract, turmeric extract and vitamin E for 15 days before 131I exposure demonstrated significant reduction in the salivary gland weight. No major histopathological changes were observed in the salivary gland of...
