摘要 目的 探讨前列腺素E2 (PGE2 )免疫干预对大鼠急性坏死性胰腺炎 (ANP )的白介素 -10(IL 10 )、肿瘤坏死因子α(TNF α)、一氧化氮 (NO )及其相关酶类黄嘌呤氧化酶 (XOD )、超氧化物歧化酶 (SOD )的影响。方法 SD大鼠 91只随机分 4组 :假手术组 (n =7) ,ANP组 ,PGE2 前、后干预组 (每组n =2 8) ,后三组随机分 1h ,3h ,6h ,12h时段组 (n =7)。大鼠ANP模型用 5 %牛磺胆酸钠诱导 ,PGE2 前干预组在ANP模型制作前 2h肌肉注射 15 0 μg/kgPGE2 ,PGE2 后干预组在ANP模型完成时即刻肌肉注射 15 0 μg kgPGE2 。分别采用ELISA和化学比色法检测各组各时段大鼠血清IL 10 ,TNF α含量及NO ,SOD ,XOD活性。结果 PGE2 前、后干预组所有时段TNF α含量均比ANP组降低 (P <0 .0 0 1) ,除后干预组 1h时段外 ,前、后干预组其余时段XOD活性均较ANP组降低 (P <0 .0 1) ;PGE2 前、后干预组分别在 3h和 6h时段IL 10含量 ,SOD ,NO活性较ANP组升高 ,差异有显著意义 (P <0 .0 1)。结论 PGE2 前、后干预均提高ANP大鼠IL 10含量 ,NO ,SOD活性 ,降低TNF α的含量及XOD活性 ,在ANP的发病中有重要调节作用。
