| Abstract |
|
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. |
