摘要
为了探讨急性胰腺炎的发病机制,我们采用胆汁酸盐—胰蛋白酶混合液向胰导管内注射,复制出大鼠急性出血坏死性胰腺炎动物模型。实验结果:在发病后10h动物血浆脂质过氧化物(LPO)即见升高(从4.67上升到20.5nmol/ml),而同时血浆淀粉酶水平已开始下降(从6577降到2629U);心肝、肾、肺组织LPO在术后10、20h也有不同程度的升高(P<0.05或P<0.01)。作者认为:急性胰腺炎时,动物血浆、组织LPO的升高证实了自由基在此病理过程中起着重要作用;与传统用血清淀粉酶水平判断急性胰腺炎发生、发展方法相比较,血浆LPO更能反映出这一病变的发生、发展和全身器官组织受损的程度。
Acute necro-hemorrhagic pancreatitis (ANHP) was induced in rats by intra-pancreatic duct injection with a mixed solution of bile salt and trypsin. After 6- to 30-hr of operation the increase of plasma lipidperoxidant (LPO) levels from 4.67 to 20.5 nmol/ml and the fall of plasma amylase levels from 6577 to 2629 U were observed in the rats with ANHP. The values of the plasma LPO at 10-,20-,and 30-hr in the rats with ANHP were significantly higher than those in the control (P<0.05 or P<0.01). The tissue LPO levels in the liver, kidney, heart and lungs of the experimental rats at 20-hr after operation significantly increased (P<0.01), compared with the control. The results suggest that free radicals play an important role in the process of acute pancreatitis (AP). The plasma LPO level in evaluating the severity of AP, and the damage of other tissue in the development of AP may be more effective than the plasma amylase level.
