Abstract:
Objective To improve the establishment of severe acute pancreatitis model in rat. Methods 36 Sprague-Dawley rats were randomly divided into experiment or shame operation group(n=18,each). Severe acute pancreatitis was induced by injection of 4% sodium taurocholate through puncturing common bile duct with a fine needle, puncture hole was closed by medical sealant glue. Ascites volume and blood amylase were measured at 3, 6 and 12 hours after injection. Gross and histological changes of pancreas were evaluated by a scoring system. Results Pancreatic changes in the experiment group was hemorrhagic and necrosis.The ascites volume(8.52±1.05)ml,serum amylase activity(5247.17±547.07)u/L, gross and histological scores(13.6±3.92) in experiment group was significantly higher than ascites volume(1.21±0.32)ml,serum amylase activity(1289.5±176.67)u/L, gross and histological scores((0.83±0.58) in shame operation group at every time point(P<0.05). Conclusions Combined injection through common bile duct and medical sealant glue in the experiment can minimize the trauma and simplize the procedure. This method produces a reliable model with high success rate and it is an ideal severe acute pancreatitis animal model.
