ABSTRACT
Objective: To examine T-lymphocyte subsets of peripheral blood and splenic cells in rat with acute pancreatitis(AP),to investigate the changes of immune functional status in the development of acute pancreatitis.Methods: AP model was developed in adult male rats by retrograde injection of 4% sodium taurocholate in the pancreatic duct.T-lymphocyte subsets( CD3,CD4,CD8) of peripheral blood and splenic cells was measured by Flow Cytometer.Results: There was no singificant change in the stage of MAP.In the stage of SAP,the levels of CD3 and CD4 and CD4/CD8 of peripheral blood were decreased,the decrease of T-lymphocyte subsets in splenic cells was more obvious than those in peripheral blood.Conclusion:Spleen shows a negative immunologic function in the stage of SAP and promote the development of AP.
