The cervical salivary glands of the armadillo Dasypus novemcinctus was examined by light microscopy. These glands are situated on either side of the neck, divide in lobes and show a presence of a salivary bladder, associated with the main ducts of the gland. This gland is histologically a typical mixed glands, containing both mucous and serous elements, with mucous acini as the predominant secr...

A highly selective, amiloride-sensitive, epithelial sodium channel from rat colon (rENaC), composed of three homologous subunits termed alpha, beta, and gamma rENaC, has been cloned by functional expression and was proposed to mediate electrogenic sodium reabsorption in aldosterone-responsive epithelia. To determine whether rENaC could account for sodium absorption in vivo, we studied the cellu...

Salivary stone disease is the most common disease of the salivary glands. They may occur in any of the salivary gland ducts/ glands, but are most common in the submandibular gland, the reason being submandibular secretions are rich in mucus and are secreted against gravity. This report presents clinical and radiographical signs of a large ductal sialolith. Radiographical examination revealed la...

The immunohistochemical localization of basic fibroblast growth factor (FGF-2) in the submandibular glands of the rat was investigated by use of an antiserum to FGF-2. Nerve fiber bundles with FGF-2-immunoreactivity were found in association with interlobular ducts and blood vessels; they dissociated into single immunoreactive nerve fibers perhaps to terminate in proximity to acinar cells, or t...

The anatomy of dog salivary glands was studied on cadaver heads. The mandibular duct enters the oral cavity on the sublingual caruncle. The parotid gland duct enters the oral cavity on the cheek opposite the 4th upper premolar tooth. The zygomatic salivary gland duct enters the oral cavity opposite the first upper molar tooth. Prior to applying sialography to live animals, catheterization, inje...

Sialolithiasis is the occurrence of calcareous concretions in the salivary ducts or glands. It is the most common pathological condition affecting the major salivary gland. It has an incidence of 0.012% in the adult population [1]. Males are more commonly affected than females with a peak incidence in 4th to 6th decades of life [2]. Most salivary calculi occur in submandibular gland (80-90%) fo...

increased nitric oxide (no) formation is mechanistically linked to pathophysiology of the extrahepatic complications of cirrhosis. no is formed by either enzymatic or non-enzymatic pathways. enzymatic production is catalyzed by no synthase (nos) while entero-salivary circulation of nitrate and nitrite is linked to non-enzymatic formation of no under acidic ph in the stomach. there is no data on...

We used pharmacological methods to test the hypothesis that female Dermacentor variabilis salivary ducts dilated when dopamine-stimulated and that dilation was nitric oxide-mediated. Stimulation with dopamine resulted in an increased diameter (19.7%) compared to unstimulated ducts (P<0.005). Pretreatment with L-NAME, an inhibitor of nitric oxide synthase, or cytochalasin D abolished the dilatio...

Ranula is a cystic fluid filled cavity that caused by extravasation of the sublingual gland at floor mouth. originates in body gland, especifically Rivinus ducts and occasionally minor salivary glands mouth .There are variety treatment modalities for ranula including aspiration fluid, sclerotherapy, marsupialization, incision drainage, excision only, with or without ranula. In this article we p...
