The biliary trees descend from the canaliculi at the hepatocytes in the liver. Bile drains from this level into intrahepatic ducts, smaller ducts combine to form the segmental bile ducts which within the liver gradually enlarge and merge to the right and left hepatic ducts. The right and left hepatic ducts join together to form the common hepatic duct (CHD) at porta hepatis. The common bile duc...
Ductal occlusion has been postulated to precipitate focal pancreatic inflammation, while the nature of the primary occluding agents has remained elusive. Neutrophils make use of histone citrullination by peptidyl arginine deiminase-4 (PADI4) in contact to particulate agents to extrude decondensed chromatin as neutrophil extracellular traps (NETs). In high cellular density, NETs form macroscopic...
Pancreas secretes fluid rich in digestive enzymes and bicarbonate. The alkaline secretion is important in buffering of acid chyme entering duodenum and for activation of enzymes. This secretion is formed in pancreatic ducts, and studies to date show that plasma membranes of duct epithelium express H(+)/HCO(3)(-) transporters, which depend on gradients created by the Na(+)/K(+)-ATPase. However, ...
This study aimed to explore the histomorphology of pancreatic tissue medaka fish develop as a diabetic animal model. Adult were obtained with body length 2.53±0.22 cm and weight 265.8±25 g. Medaka fixed using Boiun's fixative solution. Macro anatomical observations pancreas conducted stereomicroscope. Histological preparations made according Hematoxylin-eosin staining standard procedure. Pancre...
The three-dimensional architecture of the rat exocrine pancreas was studied by scanning electron microscopy (SEM) with the HCl digestion method. The treatment with HCl effectively removed connective tissue elements enclosing the ducts and the acini. Thus their shapes and relations were clearly revealed under the SEM. Furthermore fine surface features of the acinar or ductal cells were also demo...
CONTEXT The identification of genes involved in tumorigenesis is essential for the development of new treatment strategies or diagnostic approaches for pancreatic cancer. OBJECTIVE To identify genes overexpressed in pancreatic cancer we employed differential display, a PCR-based method of differential expression cloning. Using this method, we identified a PCR product that was consistently ove...
mucoepidermoid carcinoma of the pancreas is rare. here, a 63-year-old woman with left upper abdominal pain and abdominal distension is presented. her mucoepidermoid carcinoma was located at the left upper abdomen, arising from the pancreatic body and tail without invasion of pancreatic capsule. on pathologic examination, the tumor consisted of three types of cells, the majority being poorly dif...
A 60-year-old Caucasian male underwent a total pancreatectomy for a mixed type pancreatic intraductal papillary mucinous neoplasm (IPMN) arising in the main and secondary pancreatic ducts. During surgery, a subserosal polypoid mass was noted at the greater curvature of the gastric antrum and was enucleated. This mass was proven to be heterotopic pancreatic tissue with cystic neoplasia of the IP...
AIM To determine whether pancreatic enzymes are present in hepatic bile and in intrahepatic bile duct epithelium. METHODS The activity and proteins of pancreatic enzymes (pancreatic alpha-amylase, lipase, trypsin/trypsinogen) in hepatic bile were investigated using biochemical and western blot analyses in 25 patients with extrahepatic bile duct obstruction. Immunolocalization of enzyme protei...
