摘要: 目的 观察重症急性胰腺炎(SAP)时空肠组织酶活性的变化.方法将大鼠随机分为假手术组(SO组,开腹后牵拉十二指肠、胰腺)、SAP组(用逆行胰胆管注射牛磺胆酸钠复制SAP模型)、谷氮酰胺(Gln)治疗组(SAP+Gln组,制作SAP模型后用Gln治疗),于术后24 h、48 h、72 h分批处死动物,用组织化学染色法对空肠组织中碱性磷酸酶(ALP)、ATPase酶、细胞色素C氧化酶(CCO)、琥珀酸脱氢酶(SDH)进行染色,观察比较酶活性变化及其规律.结果 SAP组ALP、ATPase、CCO、SDH活性明显降低,且随病程发展呈进行性下降,经过Gln治疗后酶的活性显著恢复.结论 SAP时肠道功能随病情进展而下降,谷氨酰胺具有保护肠道功能的作用.

Abstract: Objective To investigate the changes of enzymes activities of jejunum in rats with severe acute pancreatitis(SAP).Methods Rats were divided randomly into 3 groups:sham operation group (SO), SAP group, and treatment group with Gln (SAP+Gln).SAP model was reproduced by retrograde infusion of sodium taurocholate solution into the biliopancreatic duct. In addition, the SAP+Gln group was feeded with glutamine after operation. Tissues of jejunum were taken at 24 h, 48 h and 72 h respectively after operation, and the activities of alkaline phosphatase, ATPase, cytochrome oxidase, succinate dehydrogenase were studied using enzyme-histochemistry staining.Results The activities of ALP,ATPase,CCO,SDH decreased significantly in SAP group,while Gln could increase them significantly.Conclusion It suggest that the intestinal function was impaired in SAP.Gln could protect intestinal function.
