Objective To explore the dose-effect relationship and optimal concentration of sodium taurocholate (NaTc) to establish acute necrosis pancreatitis (ANP) complicating MODS in a rat. Methods 280 SD rats were randomly divided into control group (n =40) and 3.5%, 4%, 4.5%, 5% ANP group (n = 60, respectively). ANP groups were induced by retrograde injection of NaTc solution into the pancreatic duct of rats. Rats in each model group were sacrificed at 1, 3, 6, 12 and 24 h after the model induction. Serum amylase, serum total bilirubin, creatinine, blood gas analysis, and pathological changes of pancreas were determined. Survival rate at 24 h after the model induction was observed in other 20 ANP rats in each group. Results In each groups, the serum amylase level, creatinine, blood gas analysis and pathological changes all increased corresponding to the increase of NaTc, and there was significant dose-effect relationship and time-effect. In 4.5% group, the dysfunction of liver and kidney reached the peak at 6 h,while the respiratory dysfunction reached its peak at 12 h. Its incidence of MODS was 52.5%, which was significantly higher than those in 3.5%, 4.0% group (15.0% and 37.5%) ;and 24 h survival rate of 4.5% group was 65%, which was significantly higher than that in 5% group (30%). Conclusions 4.5% NaTc solution may be the optimal concentration to establish the ANP model, which had higher incidence of MODS and 24 h survival rate.

Objective To investigate the time-course change of intra-abdominal pressure (IAP), TNF-α in rat with acute necrotizing pancreatitis (ANP) and its mechanism. Methods 80 SD rats were randomly divided into ANP group and control group. ANP group was induced by retrograde injection of 4.5% sodium taurocholate into the pancreatic duct in SD rats, while control group was induced by injection of saline at the same dosage. Eight rats in each group were killed at 1 h, 3 h, 6 h, 12 h and 24 h, respectively. The serum levels of amylase, TNF-α were determined;IAP, amount of abdominal ascites, pancreatic pathologic changes were evaluated. Results The levels of amylase in ANP group increased progressively with time, which were 32-folds higher than those in control group at 24 h. The serum levels of TNF-α in ANP group reached the peak at 6 h, and were significantly higher than those in the control group. The amount of abdominal ascites increased post-ANP induction and reached the peak at 24 h, which was 4.7-folds higher than that in the control group. The IAP significantly increased 1 h after induction, which was 3 times as high as the control group in 3 h group and 9 times in 12 h group. Pathologic injuries deteriorated progressively and reached the peak at 24 h. Conclusions Significant IAP occurred in ANP rats and reached the peak at 12 h, TNF-α reached the peak at 6 h, therefore IAP may be the secondary response to inflammatory reaction.
