Ca(2+) signals mediate the hepatic effects of numerous hormones and growth factors. Hepatic Ca(2+) signals are elicited by the inositol trisphosphate receptor, an intracellular Ca(2+) channel. Three isoforms of this receptor have been identified; they are expressed and regulated differently. We investigated the effect of liver fibrosis and cirrhosis on the hepatic expression of the inositol tri...

We previously described a selective bile duct ligation model to elucidate the process of hepatic fibrogenesis in children with biliary atresia or intrahepatic biliary stenosis. Using this model, we identified changes in the expression of alpha smooth muscle actin (α-SMA) both in the obstructed parenchyma and in the hepatic parenchyma adjacent to the obstruction. However, the expression profiles...

conclusions this study showed that the frequency of bilin was low among iranian patients with psc. high bilirubin and ca19-9 can be predictors of the development of bile duct epithelial changes in patients with psc. background primary sclerosing cholangitis (psc) as one of the most common chronic cholestatic liver diseases is a main predisposing factor for the development of cholangiocarcinoma ...

background bile duct injuries (bdi) during cholecystectomy are now being recognized as major health problems. objectives herein, we present our experience with handling major bdis and report long-term outcome of hepaticojejunostomies followed by trans-jejunal hepatic duct stenting performed to reconstruct extra-hepatic biliary tracts. materials and methods in this case series, we prospectively ...

lead poisoning has several clinical manifestations so the diagnosis may be troublesome. these manifestations consist of anemia, neurologic abnormalities, liver and biliary tract problems and abdominal pain. not only opium addiction, but also lead toxicity can cause biliary tract problems.when both etiologies occur at the same time, the diagnosis is difficult. a 46 year old opium addicted man wi...
