introduction sialolithiasis is the most common disease of salivary glands. sialography is particularly important for the assessment of the outflow tract and in diagnosing obstructive salivary gland lesions including calculi. case presentation we report on a 38-year-old female with sialolithiasis whom had wharton’s duct perforation, complicating the sialography. she was treated conservatively wi...

INTRODUCTION The lesions of the salivary ducts may be idiopathic, post- traumatic, or iatrogenic and lead to sialocele formation with persistent painful facial swelling or cutaneous fistula formation. No consensus on treatment of this condition exists: the options of treatment include needle aspiration, pressure dressings, antisialogogue therapy, radiotherapy, botulinum toxin and surgical appro...

Patterns of salivary HCO(3)(-) secretion vary and depend on species and gland types. However, the identities of the transporters involved in HCO(3)(-) transport and the underlying mechanism of intracellular pH (pH(i)) regulation in salivary glands still remain unclear. In this study, we examined the expression of the Na(+)-HCO(3)(-) cotransporter (NBC) and its role in pH(i) regulation in guinea...

Patterns of salivary HCO3 secretion vary and depend on species and gland type. However, the identities of the transporters involved in HCO3 transport and the underlying mechanism of intracellular pH (pHi) regulation in the salivary glands still remain unclear. In this experiment, we examined the expression of the Na/HCO3 cotransporter(NBC) and its role in pHi regulation in guinea pig salivary g...

The aim of the present study was to determine different affections of the salivary ducts in buffaloes with special reference to diagnosis and treatment. The study was carried out on 39 buffaloes suffering from different affections of the salivary ducts. The recorded affections of the salivary ducts in buffaloes include; ectasia of the parotid duct (21 cases), parotid duct fistula (15 cases) and...

Duct epithelial structure is an essential feature of many internal organs, including exocrine glands and the kidney. The ducts not only mediate fluid transfer but also help to maintain homeostasis. For instance, fluids and solutes are resorbed from or secreted into the primary fluid flowing through the lumen of the ducts in the exocrine glands and kidneys. The molecular mechanism underlying the...

What are the developmental mechanisms required for conversion of an undifferentiated, two-dimensional field of cells into a patterned, tubular organ? In this report, we describe the contribution of the Drosophila Pax gene eye gone to the development of the embryonic salivary glands and ducts. eye gone expression in salivary tissues is controlled by several known regulators of salivary fate. Aft...

Salivary gland metaplasia is a newly recognized, adenosis-like lesion which could not be classified according to known categories of adenosis of the breast. We report a case of basaloid ductal carcinoma in situ (DCIS) arising in a background of salivary gland metaplasia in a 49-year old woman who visited our hospital for a right breast mass. Breast ultrasonography showed a multi-lobulating mixe...

MAJOR SALIVARY GLANDS OF BOTH HUMANS AND RODENTS CONSIST OF THREE PAIRS OF MACROSCOPIC GLANDS: parotid, submandibular, and sublingual. These glands secrete serous, mucous or mixed saliva via the proper main excretory ducts connecting the glandular bodies with the oral cavity. A series of discoveries about the salivary ducts in the 17th century by Niels Stensen (1638-1686), Thomas Wharton (1614-...

We describe our preliminary experience with the half-Fourier acquisition single-shot turbo spin-echo (HASTE) sequences for MR imaging of the salivary gland ducts. In the majority of patients, the main parotid and/or submandibular gland ducts and large branches within the glands were detectable on MR images obtained in 2 seconds per section and within 3 minutes for the entire examination. MR sia...
