Methods: One hundred and sixty-two adult male SD rats with the body mass of 250–280 g were randomly divided into the following 5 groups: sham operation group (n=18), control group (n=36), Yihuo Qingyi Decoction treatment group (n=36), r-Sak treatment group (n=36), and Yihuo Qingyi Decoction plus r-Sak treatment group (n=36). The SAP ratmodel was prepared by retrograde injection of 5% sodium taurocholate into the cholangiopancreatic duct. Two days before modeling, Yihuo Qingyi Decoction was intragastrically administrated, and r-Sak was intraperitoneally injected. The survival rate within 18 h after modeling was determined. The pancreatic blood flow, the weight of ascites, and the serum amylase and lipase were investigated at 6 h, 12 h, and 18kh after modeling, and the pancreatic tissue was examined under light microscopy to see its pathological change. Results: The 18 h survival count of group A,B,C,D and E rats was 9,2,6,7 and 8 respectively. After r-Sak and Yihuo Qingyi Decoction intervention, the serum amylase and lipase and the weight of ascites were significantly decreased, especially in group E.18 h after modeling, the level of the serum amylase and lipase and the weight of ascites in group E was 1 100±118 U·L-1,1 000±150 U·L-1 and 13.40±1.80 g respectively, obviously lower than that of group B (P<0.05).After SAP was induced, the pancreatic blood flow showed a tendency to decrease, but the decrease extent in the treatment groups was smaller than that in the control group.18h after modeling, the pancreatic blood flow in group B and group E was 30.16±8.96 mL·100 g-1·min-1,and 129.10±42.58 mL·100 g-1·min-1 respectively, there was significant difference (P<0.05). The pathological change of the pancreatic tissue was alleviated in the treatment groups. Conclusion: Both r-Sak and Yihuo Qingyi Decoction play a beneficial role in the treatment of rat SAP and there is a synergistic effect between the two.展开更多
