Fascioliasis is a health problem in several countries including the Islamic Republic of Iran.  In a review of the medical publications during 1990-2002, only 22 cases of biliary tract obstruction by fasciola hepatica have been reported.  Herein, we are adding a new case of fasciola hepatica causing bile duct obstruction and presenting with intermittent colicky pain, eosinophilia and bile duct d...

Recently, we reported that primary cultures of inner medullary collecting duct cells from Dahl salt-sensitive (S) rats absorb more Na+ than do cells cultured from Dahl salt-resistant (R) rats. To begin to evaluate the molecular basis for this difference, we selected four candidate gene products that on the basis of their physiology and genetics could participate in regulation of Na+ transport b...

Extrahepatic biliary system presents with numerous variations. Anatomical knowledge of the cystic duct, common hepatic duct, common bile duct and the surrounding vessels is necessary to avoid iatrogenic ductal injuries and inadvertent complications during biliary surgery. This study reports the presence of duplicated cystic duct in a fifty-year old male cadaver. The gallbladder in this case was...

Lipocalins are secreted cup-shaped glycoproteins that bind sterols, fatty acids, and other lipophilic molecules. Lipocalins have been implicated in a wide array of processes related to lipophilic cargo transport, sequestration, and signaling, and several are used as biomarkers for human disease, but the functions of most lipocalins remain poorly understood. Here we show that the Caenorhabditis ...

Options for managing the common bile duct during laparoscopic cholecystectomy include routine peroperative cholangiography and selected preoperative endoscopic retrograde cholangiopancreatography (ERCP). The use of these methods was reviewed in 350 patients with symptomatic gall stones referred for laparoscopic cholecystectomy. Unit A (n = 114) performed routine cystic duct cholangiography but ...

purpose: to compare the success rate of external dacryocystorhinostomy (dcr) with and without bicanalicular silicone intubation for the management of primary acquired nasolacrimal duct obstruction. methods: in this study, 51 eyes from 50 patients who were diagnosed with primary acquired nasolacrimal duct obstruction underwent external dcr. patients with history of trauma and/ or surgery in the ...

purpose: primary acquired nasolacrimal duct obstruction (pando) is an acquired disease characterized by persistent symptoms such as tearing, mucus secretion, recurrent conjunctivitis and eye irritations. different etiologies such as conjunctival infections, and nasal and sinus diseases have been proposed. pathological studies have revealed inflammation, vascular congestion and edema in the earl...

Short-circuit current (I(sc)) technique was used to investigate the role of testosterone in the regulation of chloride secretion in cultured rat efferent duct epithelia. Among the steroids tested, only testosterone, and to a lesser extent, 5alpha-dihydrotestosterone (5alpha-DHT), reduced the basal and forskolin-induced I(sc) in cultured rat efferent duct epithelia when added to the apical bathi...

No studies have explored the risk factors for paraurethral duct dilatation following paraurethral duct infection by Neisseria gonorrhoeae in men undergoing ceftriaxone therapy. The present study was performed to explore the risk factors for paraurethral duct dilatation following paraurethral duct infection by N. gonorrhoeae in men undergoing ceftriaxone therapy and thus guide clinical intervent...

Bile duct injury can occur more frequently during laparoscopic cholecystectomy than in open cholecystectomy. Three cases of common bile or hepatic duct injuries occurred in a series of eighty laparoscopic cholecystectomies; In case 1, the common bile duct was misidentified as the cystic duct. In case 2, bile peritonitis occurred on the fourth postoperative day caused by necrosis of the common h...
