S TUDIES OF THE CELLULAR EFFLUENT of the thoracic duct of the calf were undertaken to provide background information to be used in interpretations of changes in agranubocytes#{176} observed in experimentally immunized calves as well as in preleukemic and leukemic cattle. This report concerns an attempt to characterize the ultrastructure of the various agranulocytes encountered in the thoracic d...

Autoimmunity to salivary duct cells has been suggested in Sjögren's symdrome (SjS). We were interested in the secretory component (SC) of secretory IgA (s-IgA) as a common duct cell antigen of systemic exocrine glands because of the possible analogy between SC in SjS and thyroglobulin in Hashimoto's thyroiditis. Therefore, we isolated s-IgA as a source of SC from human milk and investigated lym...

Background: Persistent thyroglossal duct leads to a fibrous cyst formation named thyroglossal cyst which is the most common form of congenital cyst and usually located in the midline neck below the hyoid bone. Rarely the thyroglossal cyst is associated with thyroid cancer. Although the Sistrunk procedure is often considered adequate, currently there is no clear consensus on the optimal manageme...

purpose: to evaluate the effect of stenosis nature on success of silicone intubation for nasosolacrimal duct stenosis (nlds) in adults (patent nasolacrimal duct with resistance to positive-pressure irrigation) methods: an interventional case series of consecutive monocanalicular and bicanalicular silicone intubation for nasolacrimal duct stenosis in adults were reviewed. the severity of the ste...

Regeneration or extensive new growth of the pancreatic duct has been report,ed by Fisher (1924b), and regeneration of pancreas tissue (acini and islets) from the pancreatic duct tissue have been reported by several investigators, Languesse and de la Roche (1902), Cecil (1911), Bensley and Clark (1914). These observations deal with regeneration of pancreas from duct tissue left in situ, such as ...

purpose:  to determine the safety and efficacy of mitomycin-c injection into the lacrimal duct for treatment of partial nasolacrimal duct obstruction in adults. method: this is a before-after clinical trial performed on 20 patients with partial primary acquired nasolacrimal duct obstruction. we injected 1.5 ml of mitomycin-c 0.2 mg/ml into the lacrimal duct and repeated it with concentration of...

introduction: solitary fibrous tumor is a rare, mesenchymal neoplasm that has been reported in numerous sites. occurrence in the parotid gland is exceedingly rare.   case report: a 53-year-old man with a 2 cm solitary fibrous tumor of the left parotid gland, that was observed clinically and operatively and thought to be a neoplasm arising from stensen's duct, is described. a pre-operative ...

A 38-year-old man with chronic pancreatitis caused by heavy alcohol consumption presented with recurrent abdominal pain due to underlying pancreatic duct calculi and stricture of the main pancreatic duct (▶Fig. 1 a). Endoscopic cholangiopancreatography (ERCP) was performed and a plastic pancreatic stent was inserted, which relieved the pain. Attempts at stricture dilation with a dilation balloo...

background: narcotic addiction is one of the most important problems in human communities that unfortunately it's prevalence has been increased in our country inconveniently. opium has various effects on the parts of body. many studies has been performed about these effects, but opium effect on common bile duct has allocated only small quantity. materials and methods: this study is a cross-sect...
