A bile duct lesion originating from intrahepatic bile ducts is generally regarded as an incidental pathologic finding in liver specimens. However, a recent study on the molecular classification of intrahepatic cholangiocarcinoma has focused on the heterogeneity of this carcinoma and has suggested that the cells of different origins present in the biliary tree may have a major role in the mechan...

Electron microscopic and other evidence have provided support for the hypothesis that the sickling phenomenon is due to the intracellular formation of long slender crystals of reduced sickle hemoglobin. The rapid growth of these crystals causing tenting of the cell membrane is responsible for the bizarre distortion of the erythrocytes and presumably for the disease itself.

Rats were injected with [(3)H]leucine, and at various times thereafter labelled albumin was isolated by electrophoresis from their livers and blood plasma. The specific radioactivity of each protein was determined by spectrophotometry and liquid-scintillation spectrometry. Intrahepatic albumin was shown to be identical with plasma albumin by its electrophoretic mobility and antigenicity. It was...

Intrahepatic cholangiocarcinoma (ICH) is one of the most aggressive malignant neoplasms gastrointestinal tract, which accounts for 10–15% all primary liver tumors. Among risk factors ICH in Europe and Russia, diseases accompanied by formation concretions intrahepatic bile ducts, include Karoli's disease (KD), are importance. The article presents a clinical observation HPV that developed against...

INTRODUCTION The intrahepatic hepatitis B surface antigens (HBsAg) expression is related to disease progression of chronic hepatitis B. We examined the features of intrahepatic HBsAg expression. MATERIAL AND METHODS A total of 181 patients with e antigen positive chronic hepatitis B were enrolled. Patterns and semi-quantitative measurement of intrahepatic HBsAg expression were analyzed. The a...

Intrahepatic stones remain a major source of morbidity and mortality. With improving techniques in hepatobiliary surgery, the management and the outcome of intrahepatic calculi is reviewed. Forty-nine cases referred from all over Malaysia between January 1993 to June 1996 were analyzed retrospectively. There were thirty-two females and seventeen males. The median age was 46 years. Biliary disea...

Intra- or extrahepatic cholangiocarcinomas are the second most common primary liver malignancies behind hepatocellular carcinoma. Whereas the incidence for intrahepatic cholangiocarcinoma is rising, the occurrence of extrahepatic cholangiocarcinoma is trending downwards. The treatment of choice for intrahepatic cholangiocarcinoma remains liver resection. However, a case of liver resection after...

Cholangiolocellular carcinoma is a minor primary cancerous tumor of the liver and its coexistence with intrahepatic cholangiocarcinoma in the liver is rare. We herein report a case of concurrent cholangiolocellular carcinoma and intrahepatic cholangiocarcinoma in the liver, in addition to a rectal G1 neuroendocrine tumor, a so-called carcinoid. The intrahepatic tumors showed a different uptake ...

SEVERAL HEMOGLOBINOPATHIES of man are known to produce striking morphologic changes in erythrocytes. In vivo sickling, occurring under low oxygen tension, is well documented in hemoglobin 5 (1-lb S) disease. Osmotic dehydration produced by incubation in hypertonic salt solutions fosters sickling in these cells.’ This phenomenon is explained on the basis of a single amino acid substitution, vali...
