ABSTRACT  BACKGROUND: PIXE (Particle Induced X-Ray Emission) is a suitable method for the analysis of biological samples in which heavy trace elements are contained in light matrix elements. It is very important to know which factors or probably elements act as initial seed and lead to growing the sands. The goal of this study was to compare the relative values of Fe/K, Cu/K and Zn/K for gallst...

aim : to assess the complications of bile duct injury in laparoscopic cholecystectomy in loghman medical center, tehran. background : the incidence of complications of laparoscopic cholecystectomy has increased dramatically since the introduction and widespread use of laparoscopic cholecystectomy.  patients and methods : from january 1998 to january 2002, a total of 155 laparoscopic cholecystec...

total petroleum hydrocarbon ( tph ) are environmental contaminants that are released into the marine environment through oil spills, industrial and domestic activities. tph are readily transformed into more hydrophilic metabolites, which are accumulated in bile. thus fish bile can be used as a biomarker of exposure of fish to tph in the marine environment. in this study several stations were se...

Lactobacillus strains are a major part of the probiotics, microflora of the intestine and of fermented dairy products, and are found in a variety of environments. The aim of this study was to find out the ability of bile and acid tolerance and antibacterial properties of the twenty eight isolates of three group lactobacilli namely Lactobacillus plantarum, Lactobacillus casei and Lactobacillus d...

Background: Cholangiocarcinoma is an invasive biliary malignancy with poor prognosis. Diagnostic accuracy of conventional methods is low which is mainly due to the specific anatomy of the disease. The aim of this study was to evaluate the diagnostic value of biochemical profile and tumor marker of the bile in patients with malignant cholestasis compared to that of choledocholithiasis. ...

Philips CA, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-221324 Description A 70-year-old male teetotaller, with a history of chronic obstructive lung disease and hypertension, presented to the emergency department with a 2-day history of right upper quadrant pain and melaena. Investigations revealed total bilirubin 6.8 mg/dL, aspartate and alanine transaminases 88 and 122 IU/L, respectively,...

In vitro excystment studies on the metacercaria of Acanthoparyphium spinulosum indicated that optimal excystment occurred when the cysts were incubated in either a complete medium containing trypsin and bile salts, or bile salts alone following acid pretreatment, and the reductant (sodium dithionite) at a temperature of 42°C and a pH of 7.8. A relatively lower percentage of excystment was obtai...

carcinoid tumors of the bile duct are rare. despite cholangiocarcinoma, they grow more slowly and generally occur in younger patients and females. these tumors have a better prognosis and more disease-free survival. we present the case of a 25-year- old male with common bile duct (cbd) carcinoid tumor misdiagnosed as cholangiocarcinoma.

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...
