摘要: 探讨了胰蛋白酶原激活肽(TAP)在预测大鼠实验性急性胰腺炎严重程度中的意义。将90只大鼠按抽签法随机分为5组:EP和NP(3%和5%牛磺胆酸钠逆行胆胰管注射)组,TP(乌司他丁治疗)组,CP(生理盐水对照)组,OP(假手术)组。用酶联免疫法测定各组制模后3、6、24h的血浆TAP浓度。结果:制模后3h和6h血浆TAP浓度NP组〔(4.798±0.169)、(3.999±0.299)nmol/L〕比EP组〔(2.416±0.148)、(3.356±0.211)nmol/L〕明显增高(P<0.01);在制模6h后TP组血浆TAP浓度(1.611±0.113)nmol/L,比EP组明显降低(P<0.01).提示:血浆TAP浓度可以作为预测急性胰腺炎严重程度的指标.

Abstract: To investigate the generation and possible significance of plasma trypsinogen activation peptides(TAP) in experimental rats of acute pancreatitis, 90 SD rats were randomly allocated to five groups: group EP and NP with retrograde ductal infusion of 3%and 5%sodium taurocholate ; group TP with Ulinastatin(UTI) treatment; group CP with 0.9%NS retrograde ductal infusion; group OP with sham operation. Plasma TAP was determined by EIA. Result: At times 3 h and 6 h after infusion, plasma TAP concentration of group NP (4.798±0.169、3.999±0.299 nmol/L) were significantly higher than that of group EP(2.416±0.148、3.356±0.211 nmol/L); At 6 h after infusion, plasma TAP concentration of group TP(1.611±0.113 nmol/L) was significantly lower than that of group EP. The result shows that plasma TAP concentration may be used as a marker for the early assessment of the severity of pancreatitis.
