We have examined the distribution of L-ascorbic acid in rat parotid acinar cells by analysis of whole tissue, subcellular fractions, and parotid salivary secretion. Acinar cell secretion granules contain reduced ascorbate at a calculated concentration of 3.5 mM. A distinct extragranular pool, comprising as much as 80% of total cellular ascorbate, also exists in these cells. Parotid secretion, c...

PURPOSE The purpose of this study was to evaluate the effectiveness of MR sialography of the parotid gland ducts in the diagnosis and staging of Sjögren syndrome. METHODS MR imaging was performed on a 1.5-T unit with a neck phased-array coil. MR sialographic source images were obtained using a heavily T2-weighted fast spin-echo sequence with spectral fat suppression. All images were analyzed ...

A sialo-cutaneous fistula is a communication between the skin and a salivary gland or duct discharging saliva. Trauma and iatrogenic complications are the most common causes of this condition. Treatments include aspiration, compression, and the administration of systemic anticholinergics; however, their effects are transient and unsatisfactory in most cases. We had a case of a patient who devel...

BACKGROUND Acute suppurative parotitis (ASP) is a rare finding in the neonate. It is commonly caused by S. aureus but other bacterial isolates may be emerging. Effective treatment includes prompt diagnosis, parenteral antibiotics and supportive measures such as rehydration and bimanual gland massage. CASE REPORT This case report describes an extremely premature female infant with a complicate...
