【摘要】 目的　探讨急性胰腺炎病人接受肠外营养 (PN)支持后 ,抗氧化酶活性的变化及其变化机制。方法　测定 2 0例急性重型胰腺炎病人PN支持前后的过氧歧化酶 (SOD)和脂质氧化酶 (LPO)活性的变化 ,并作统计学分析。结果　PN支持后 ,SOD值平均升高 18 7% (P <0 0 5 ) ,LPO值下降 19 4% (P <0 0 5 ) ,2 0例病人均治愈。结论　PN支持能帮助损害机体的氧自由基 (OFR)的清除 ,能增强病人抗氧化损伤的能力。更多还原

【Abstract】 Objective To investigate antioxidase activety change and its change mechanism post parenteral nutrition (PN). Methods The superoxide dismutase (SOD) activety and lipoxidase (LPO)ativety in 20 patients with acute severe pancreatitis was measured respactively preparenteral nutrition (PN) and post PN, and satistical analgsis was done. Results The SOD activety post PN was risen 18 7%( p <0 05), the LPO activety was downed 19 4%( p <0 05), 20 patients were curred. Conclusions PN can help eliminate oxygen free radical (OFR)which damages body,and can increase the ability of patients antioxide damage.更多还原
