Adult rat submandibular glands have a rich autonomic innervation, with parasympathetic and sympathetic nerves working in synergy rather than antagonistically. Ligation of the secretory duct rapidly causes atrophy and the loss of most acini, which are the main target cell for parasympathetic nerves. Following deligation, there is a recovery of gland structure and function, as assessed by autonom...

OBJECTIVES/HYPOTHESIS Onabotulinum toxin A (OBTXA) injection is a well-established therapeutic option for the management of drooling. Many of the children treated undertake repeated injections every 3 to 6 months. We aimed to assess quantitative salivary gland changes via ultrasound imaging after intraglandular injection of OBTXA for sialorrhea treatment in children, as a method that suggests p...

Neonatal rats treated with chronic injections of isoprenaline (isoproterenol) for 10 days revealed differential induction of proline-rich proteins and glycoprotein synthesis between the parotid and submandibular glands. Biosynthesis of proline-rich proteins (Mr 17000-35000) and a Mr-220000 glycoprotein were detectable by solubilization in 10%-trichloroacetic acid extracts from parotid glands 14...

OBJECTIVE To comparatively analyze the ultrastructural changes in the submandibular and parotid glands and in the exocrine pancreas following diabetes induced by Streptozotocin exposure and the effects of fasting and insulin treatment on these alterations. METHODS For experimental procedure, we included 48 Sprague-Dawley type rats in July 2001-March 2002 at Gazi University, Turkey. We divided...

OBJECTIVES To review the findings of the patients with Sjögren's syndrome (SS) having technetium99-m-pertechnetate (99mTc-pertechnetate) and gallium67- citrate (Ga-67) salivary gland scintigraphy in the past eight years. METHODS The patients with SS, who were referred to our department for salivary gland scintigraphy during January -2008December 2015 were studied using both 99mTc-pertechnetat...

BACKGROUND AND PURPOSE Although radiation induced damage to the salivary gland is a known complication of radioactive iodine ((131)I) therapy for thyroid carcinoma, prediction of the severity and reversibility of sialoadenitis is difficult. Our aim was to correlate the extent of salivary dysfunction assessed by salivary gland scintigraphy with changes in the volume and attenuation of salivary g...

We have recently shown that salivary gland myoepithelial cells express podoplanin. Podoplanin indirectly binds the actin filament network which links classical cadherins. The study here is aimed to investigate the expression of podoplanin and cadherins on salivary gland myoepithelial cells and the changes in the aging cells using klotho-deficient (kl/kl) mice. The submandibular glands of kl/kl ...

Epithelial myoepithelial carcinoma is a rare biphasic low grade neoplasm of salivary glands; it most commonly occurs in the parotid gland but can also arise in minor salivary glands. Here a case of 58-year-old female presented with left cheek swelling of one-year duration. CT scan revealed a localized submandibular salivary gland tumor mass not involving surrounding tissues. Histological examin...

Still little is known about the role of oxidative stress (OS) in the pathogenesis of the salivary gland dysfunction in the course of insulin resistance (IR). To induce IR rats was fed with a high fat diet (HFD) during 8 weeks. Stimulated and non-stimulated salivary flow rate, total protein, as well as oxidative damage markers: 4-HNE protein adduct, 8-isoprostanes (8-isoP), 8-hydroxy-D-guanosine...
