Résumé
Objective To study severe acute pancreatitis (SAP) in rats model method improvement ,these rates were given uni-form and multi-point injecting with 3 .5% of the taurocholic acid sodium in pancreas capsule .Methods 96 healthy SD rats randomly divided into SAP group (n=42) and sham-operated group (n=42) ,blank control group (n=12) .SAP group was given uniform multi-point injection of 3 .5% sodium taurocholic acid in the pancreas capsule ,Sham-operated group was injected with 0 .9% saline injection ,two groups were recorded the measurement of serum amylase values by killing 7 rats in 2 ,4 ,6 ,12 ,24 and 48 h respective-ly ,and observed pancreas in form and then pathological changes .The whole rates of control group were killed before the experiment to measure normal values of serum amylase and make normal pancreas tissue specimen as a reference .Results Each time point of the serum amylase values of SAP group were obviously increased compared with the corresponding time points sham-operated group and blank control group(P<0 .000 1) ,no difference between sham-operated group and blank control group ;Pancreas gross tissue and then observed pathological changes of SAP group are more obvious than the sham-operated group and blank control group's . Conclusion The improved injection in the pancreas capsule is an ideal method of moulding ,which can make typical SAP model and have simple operation ,induced by a high success rate ,and have the stability and low mortality rate .
