biliary papillomatosis is a disorder characterized by numerous adenomatous polyps of variable distribution and extent in intrahepatic bile ducts. it should be considered as a premalignant condition because a high proportion of the lesions undergo malignant transformation. in this report, we present a patient with abdominal pain and jaundice. according to his presenting signs and symptoms, ercp ...
Background: The incidence of complications of laparoscopic cholecystectomy has increased dramatically since the introduction and widespread use of laparoscopic cholecystectomy in 1990. Bile duct injuries are among the most important complications of this approach. Methods : From January 1998 to January 2002, a total of 155 laparoscopic cholecystectomy were performed at the Loghman Medical Cent...
the aim of this study was to examine the effect of crude bile on the human hepg2 and ccrf-cem cell lines. cells were exposed to different dilutions of bile. antiproliferative effects were determined by the cytotoxic mtt assay. cells undergoing apoptosis were identified by terminal deoxynucleotidyl transferase dutp nick end labeling (tunel) assay. bile administration resulted in dose-dependent c...
Measuring the viability of probiotic microorganisms in food products using plate count methodology is a common practice due to the simplicity (ease of performance), inexpensive and routine testing characters ofthis method. In present study, the suitability of de man rogosa and sharpe agar (MRS) bile agar medium forthe selective enumeration of mixed probiotic bacteria (Lactobacillus ...
liver functional tests due to inflammatory process which induced by cholecystitis might changed and some clinicians suggested that these changes might help us to stone prediction in common bile ducts and decrease hazards of performing ercp and other invasive procedures. present study was performed for assessment of role of liver functional test in diagnosis of common bile duct stone in patients...
Abstract Background and objectives: Bile in healthy people is a sterile fluid and presence of any microorganism can be a marker for a disorder like cholelithiasis. The aim of this study was to determine the frequency of bacterial agents in the bile of patients with bilestone, malignant pancreatic and biliary diseases. Material and Methods: One hundred and two bile samples were obtained, during ...
The aim of this study was to examine the effect of crude bile on the human HepG2 and CCRF-CEM cell lines. Cells were exposed to different dilutions of bile. Antiproliferative effects were determined by the cytotoxic MTT assay. Cells undergoing apoptosis were identified by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Bile administration resulted in dose-dependent c...
Introduction: Increase in the common bile duct diameter after cholecystectomy has been reported in animal model. However, similar studies in the human resulted in controversy. Methods: Between 2008 and 2012, fifty two patients with clinical as well as radiological signs and symptoms of gallbladder disease were enrolled in this study. The patients underwent laparoscopic and open cholecystectomy ...
ABSTRACT Background and Objective: In this study, we compared the susceptibility of Salmonella typhimurium phoP mutant and its parent to stress conditions that the pathogen may encounter in a host. Methods: For this purpose, we used the phoP deletion mutant constructed in our previous study. In order t...
