Experimental study on ulinastatin combined with qingyitang in treatment of severe acute pancreatitis of rats / 中国综合临床

ABSTRACT

Objective To investigate the changes of serum concentration of amylase(AMY) and pathological of pancreas in severe acute pancreatitis of SD-rats treated with Ulinastatin combined with qingyitang and to provide the basis for clinical application.Methods Ninty male SD-rats with average weight of(271.59±11.13) g were conventional feeding for a week.Twelve hours before experiment,they were forbidden to take food.They were randomly divided into five groups(with 18 in every group)sham operation group,severe acute pancreatitis group,Ulinastatin treated group,qingyitang treated group,Ulinastatin combined with qingyitang treated group.Then eighteen rats in every group were divided randomly into 6 h,12 h and 24 h groups with six rats in each group.Severe acute pancreatitis model was created by retrograde injection of 5％ sodium taurocholate (0.1 ml/100 g) through pancreatic duct,in sham operation group,only pancreas were flipped.The three treated groups were treated with vein injection of Ulinastatin(20 000 U/kg)or qingyitang perfusion(1 ml/100 g)or Ulinastatin combined with qingyitangat 0 h,5 h and 11 h after severe acute pancreatitis model successfully created.AMY and patholigical changes of pancreas were measured.Results There was significant difference on AMY level at 6 h,12 h and 24.h between severe acute pancreatitis group and sham operation group[6 h(16 518±327)U/L vs(1671±175)U/L,F =3296.24,P ＜0.01;12 h(16 796±338) U/L vs(1751±223)U/L,F =3802.44,P ＜0.01;24 h(1554±373) U/L vs(1724±187) U/L,F =2382.54,P ＜0.01].Compared with severe acute pancreatitis group,the AMY level and pathologic score both decreased significantly in Ulinastatin treated group,qingyitang treated group and Ulinastatin combined with qingyitang treated group(P ＜0.05 or P ＜ 0.01).At the same time,the AMY level and pathologic score both decreased more in Ulinastatin combined with qingyitang treated group than Ulinastatin treated group and qingyitang treated group(P ＜0.05 or P ＜ 0.01).Conclusion Combination of Ulinastatin with qingyitang in treatment of severe acute pancreatitis of rats is superior to treatment with single medicine.
