the aim of this study was to investigate the radioprotective effect of thymol as a natural product against salivary glands dysfunction induced by ionizing radiation in rats. the rats were treated with thymol at dose of 50 mg/kg before exposure to radiation at dose 15gy. salivary gland function was evaluated with radioisotope scintigraphy and then salivary gland to background counts ratio was ca...

Immunohistochemical staining, with a monoclonal antibody specific for cytokeratins 5, 6, 8, 17 and 19 of dog submandibular, sublingual, parotid, palatine, tongue and zygomatic salivary glands resulted in staining of myoepithelial cells, duct epithelial cells (including intercalated, striated and secretory ducts) and some acinar epithelial cells. Differences in acinar staining between glands ref...

introduction: 18f-choline pet-ct is an increasingly used technique in patients with prostate cancer. the main indication is to localise the disease in patients with biochemical recurrence. to accurately interpret 18f-choline pet, knowledge of normal tracer distribution is paramount. the aim of this study was to describe the normal distribution pattern of 18f-choline by measuring the maximum sta...

Saliva plays an essential role in maintaining oral health. Alterations in salivary function lead to compromise of oral tissues and functions and have a large impact on a patient’s quality of life. Reductions in salivary flow most commonly manifest as symptoms of oral dryness. This subjective complaint of dry mouth is termed xerostomia, whereas objective alterations in salivary performance, quan...

Submucosal glands are abundant (approximately 1 gland/mm2) secretory structures in the tracheobronchial airways of the human lung. Because submucosal glands express antibacterial proteins, it has been proposed that they contribute to lung defense. However, this concept is challenged by the fact that mice do not have submucosal glands in their bronchial airways, yet are quite resistant to bacter...

Six abomasums of yaks (Bos grunniens) were studied with gross dissection and histological methods. It was found that the mucosa of the yak abomasum was covered with simple columnar epithelium. There were lots of spiral folds (≥10) in the fundic glandular area. The developed membrane of lamina propria was occupied by high density glands. According to the morphological characteristics of the glan...

Multicellular glands in the amphibian integument represent a signifi cant evolutionary advance over those of fi shes. Bufonids have parotoid glands, symmetrically disposed in a post-orbital position. Their secretion may contribute to protection against predators and parasites. This study provides a re-evaluation of the morphology of the Bufo ictericus parotoid glands. The parotoid gland integum...
