The distribution and relative frequencies of the endocrine cells were studied immunohistochemically in the common pancreatic ducts of the Korean native goat with serotonin, glucagon, insulin, BCG, BPP and somatostatin antisera. Serotonin-, glucagon-, BCG-, BPP- and somatostatin-immunoreactive cells were detected in the basal portion of the mucosal gland in the common pancreatic ducts of the Korean native goat but insulin-immunoreactive cells were not detected. The function of these immunoreactive cells and appearance of other immunoreactive cells in the common pancreatic ducts of the Korean native goat were remains unknown.

To investigate morphological changes in the exocrine pancreas of chicken after pancreatic duct ligation, experimental animals were subdivided to control, 12 hours, 1 day, 2 days, 4 days, 7 days and 10 days groupes and all of three pancreatic ducts of chicken were ligated by surgical procedure and then the morphological changes were observed. In pancreatic ducts, once for a while the ducts were dilated on 12 hours after pancreatic duct ligation and then they were obstructed because of proliferated epithelial cells and connective tissues in pancreatic duct. Marginal dissociation of acini was detected in 12 hours after pancreatic duct ligation and then dissociation of acini was increased with time and finally in 4 days after pancreatic duct ligation the acini showed completely dissociation except periductular regions and around pancreatic islets. Most of dissociated acini cells showed marginal condensation of nuclear chromatin and atropy of cytoplasm, namely, apoptotic features were detected in dissociated acinar cells. Interacinar spaces of dissociated acinar regions were dilated and fulfilled with increased connective tissue and in 4 days after pancreatic duct ligation, deposition of lymphocytes and hemocytes was occurred.

Histopathological changes in the pancreas of bovine eurytremiasis were dilatation and thickning of the pancreatic ducts inwhich infiltration of eosinophils and lymphocytes was prominent. The mucous epithelium showed papilliferous and adenomatoid hyperplasia. Proliferation of tissue mast cells in the mucosa propria of the pancreatic ducts was recognized. In addition, granulomatous inflammation was accompanied with the death of Eurytrema in the pancreatic ducts. Granuloma formation around Eurytrema eggs which were embolized in the lung of rabbit was observed on 15 and 20 days after injection.

The distribution of glucagon-immunoreactive cells in the pancreas during various developmental stages (fetus, neonate, 1-month-old, 6-month-old and adult) of the Korean native goat was investigated by immunohistochemical methods. The varying distribution and frequency of glucagon-immunoreactive cells in the pancreas of the Korean native goat were observed. The glucagon-immunoreactive cells were detected in both exocrine and endocrine portions (pancreatic islets) at all developmental stages and also in ducts of the 6-month-old and adult. The relative frequencies of glucagon-immunoreactive cells increased in the pancreatic islets and ducts with age, but decreased in the exocrine portions. Generally, they were distributed in the interacinar spaces or marginal zone of the pancreatic islets during all stages of development. However, the cell distributions of the pancreatic islets in the neonate divided into two types: 1) ones which were distributed in the inner zone, and 2) others in the peripheral zone.

Researches to determine the infectious status on the pancreatic fluke, Eurytrema pancreaticum(Janson 1889) Looss, 1907, were made into several slaughter hauses at four different districts through seven years from 1963 to 1969. The infection rate showed 2962 positive of 5974 heads (49.6%) of cattle at the Seoul first slaughter hause in Seoul, 881 positive of 1021 heads (86.3%) in Cheju, and six(6) positive of 56 heads (11.1%) at Suwon, 58 positive of 306 heads(19.0%)at Joenju. The infection rate 53.1%, (2907 positive heads of total 7357 heads exammed) is the representative infection rate at the cattle eurytremiasis in Korea. It showed little variation through a year and was increased as compared with those of the past period, from 1915 to 1945. Fecal examinations in order to find out the local distribution of the pancreatic fluke were conducted on cattle, sheep, and goats raised in four districts, showing two(2) of 269 heads (0.7%) in Kyonggi-do, 41 of 212 heads (19.3%) in Cheju-do, and negative in both Chungnam-do and Joenbuk-do. When an artificial infection wss performed on rabbits and goats with metacercaria of the pancreatic fluke, Parenchyma of their pancreas were degenerated and the ducts were dilated. When cattle and sheep were infected naturally, the pancreatic ducts were also dilated, the wall was thickened, and adenomatous and epithelial hyperplasia was appeared. The conclusion, putting the foregoing pathological changes, has been arrived at chronic hyperplastic pancreatitis in the eurytremiasis of cattle, sheep, goats and rabbits.

To investigate morphological changes in the endocrine pancreas of chicken after pancreatic duct ligation, experimental animals were subdivided to control, 12 hours, 1 day, 2 days, 4 days, 7 days and 10 days groupes and all of three pancreatic ducts of chicken were ligated by surgical procedure and then the morphological changes were observed. In pancreatic islets, the vacuolation and invasion of connective tissue were occurred in all experimental groups and dissociation of pancreatic islets was detected in 4 days after pancreatic duct ligation and hold out to 10 days. The peak of the morphological changes in pancreatic islets was detected in 4 days after pancreatic duct ligation. In the results of immunohistochemical methods against glucagon, insulin, somatostatin and bovine pancreatic polypeptide(BPP), the number of immunoreactive pancreatic islets were decreased but the size increased with time, so the number of immunoreactive cells in each pancreatic islets were increased. Glucagon-immunoreactive cells were not changed but insulin-immunoreactive cells were decreased with time(p<0.05). BPP-immunoreactive cells were increased in 2 days after pancreatic duct ligation and then decreased with time(p<0.05). Somatostatin-immunoreactive cells were increased with time(p<0.05) in dark islets.

Objective: This study was conducted to investigate the efficacy of pancreatic drainage for pain relief in advanced pancreatic cancer. Method: Seventy-one patients with pancreatic carcinoma were divided into two groups: dilated and non-dilated pancreatic ducts. All patients underwent endoscopic retrograde cholangiopancreatography (ERCP), endoscopic biliary stenting and pancreatic stenting. Visual Analog Scale (VAS) scores, pain remission rates and survival time were evaluated during follow-up. Results: The post-ERCP VAS score of the dilated group was lower than that of the non-dilated group at 1 and 3 months post-ERCP. There was no difference at 6 months. The pain remission rate in the dilated duct group was significantly higher than that in non-dilated duct group in 1 and 3 months post-ERCP. The median survival times were 8.17 and 8.22 months respectively. Conclusion: Endoscopic pancreatic drainage can relieve pain of advanced pancreatic cancer accompanied by safe dilation of the pancreatic duct.

Portal cavernoma cholangiopathy is defined as an obstruction of the biliary system due to distended veins surrounding bile ducts that mainly occur in patients with extrahepatic portal venous obstruction. The periductal venous plexuses encircling the ducts can cause morphological changes which may or may not become symptomatic. Currently, non-invasive techniques such as ultrasonography, computed tomography, magnetic resonance cholangiopancreatography, and dynamic contrast enhanced magnetic resonance images are being used to diagnose this disorder. Only a few patients who have symptoms of biliary obstruction require drainage which might be accomplished using endoscopic stenting, decompression of the portal venous system usually via a lienorenal shunt, a difficult direct hepaticojejunostomy, and rarely a liver transplant.

Anatomical and histological changes were studied in the dorsal, ventral, third and splenic lobes of the pancreas of the chicken embryos (8 days of incubation, 10 days of incubation to hatching). From 13 days of incubation, all four pancreatic lobes, namely, dorsal, ventral, third and splenic lobes were observed. Histologically, the pancreas of 10-14 days of incubation were consisted of mesenchymal tissue, exocrine acini and pancreatic islets. But mesenchymal tissues were disappeared from 15 days of incubation. The pancreatic ducts were observed from 14 days of incubation. The dark and light typed pancreatic islets were observed in splenic lobe from 13 days of incubation, in the third lobe from 11 days of incubation, and in the dorsal lobe from 13 days of incubation. But no dark typed islets were observed in the ventral lobes.

Pancreatic trauma from a blunt injury is fairly uncommon in the pediatric population. Furthermore, such trauma with associated disruption of the pancreatic duct (PD) is even less prevalent and is associated with high morbidity and mortality. Pancreatic injuries in the pediatric population are often missed and hence require a thorough workup in children presenting with any form of abdominal injury. This case report describes a young boy who presented with abdominal pain and did not initially inform medical staff about any injury. For this reason, his initial provisional diagnosis was appendicitis, but he was later found to have transection of the pancreas with injury to the PD on imaging. The management of such injuries in pediatric patients often poses a challenge due to a lack of pediatric physicians trained to perform interventions such as endoscopic retrograde cholangiopancreatography. Furthermore, such interventions carry a higher risk when performed on children due to the smaller size of their pancreatic ducts. As a result, our patient had to be transferred to an adult center to undergo this procedure. Thus, maintaining a high degree of suspicion, along with a detailed history and examination, is crucial for the early diagnosis and management of pancreatic injuries.
