The mammalian esophagus has the capacity to secrete a HCO(3)(-) and mucin-rich fluid in the esophageal lumen. These secretions originate from the submucosal glands (SMG) and can contribute to esophageal protection against refluxed gastric acid. The cellular mechanisms by which glandular cells achieve these secretions are largely unknown. To study this phenomenon, we used the pH-stat technique t...

the aim of this study was to determine the prognosis and survival for patients with borderlineovarian tumor (bot). a retrospective review of 30 patients with serous andmucinous bot treated at or referred to our institution was performed. fifteenpatients (50%) had serous, and the others had mucinous bot. about 86% of allpatients in both groups were in stage i of the disease. the recurrent diseas...

central serous chorioretinopathy (cscr) is an ocular disease which fluid is collected under retina and leads to retinal detachment and blurred vision. risk factors for development of central serous chorioretinopathy are included: alcohol use, uncontrolled hypertension, pregnancy, type a personalityand different ways of corticosteroid use. we want to present central serous chorioretinopathy in a...

purpose: to evaluate the beneficial effects of rifampin for the treatment of central serous chorioretinopathy (cscr). methods: in this non-randomized clinical trial, 39 patients with acute cscr (<2 weeks) were enrolled. initially, complete visual examinations including determination of best spectacle-corrected visual acuity (bscva) using snellen chart; anterior and posterior segment examination...

while ovarian masses are common findings in gynecology, unusually huge masses are quite rare. however, such cases can still be found today. mismanagement of common complaints in patients can be a leading cause of facing such findings. herein, we introduce a case of a giant ovarian cyst, which was mismanaged in a young virgin female patient. the patient had received gastrointestinal medications ...

BACKGROUND To report atypical features on Spectral domain optical coherence tomography (SD-OCT) in a case of non-familial pure adult nanophthalmos. CASE PRESENTATION A 39 year old male hyperope was found to have biometric and fundus findings typical of nanophthalmos. The additional atypical features included serous pigment epithelial detachment (PED) in right eye and a cuff of subretinal flui...

introduction retrorectal cysts are rare benign lesions which are frequently diagnosed in middle-aged females. according to their origin and histopathologic features, retrorectal cysts are classified as squamous-lined (dermoid or epidermoid) cysts, postanal gut (tailgut) cysts, and rectal duplications (enteric or enterogenous cysts, enterocystomas). described in this case report is an extremely ...

ovarian borderline serous tumors are uncommon. combination of borderline serous adenofibromatous tumor and prominent micro papillary architecture is not previously reported. we report a case of borderline papillary serous adenofibromatous tumor (also called serous adenocarcinofibroma) with extensive micropapillary pattern in a 27 year-old married woman. she was infertile and presented with diff...

The electrical potential across the human colon was measured by a technique which accurately reflects the true mucosa-to-serosa potential difference. Large negative mucosal potentials were recorded from all regions. The potential difference of the sigmoid colon was significantly greater than that of the rectum. The technique may have important applications to the further study of normal or abno...
