摘要 已经证实,免疫功能异常是急性胰腺炎病情恶化的重要因素[1,2].推测免疫抑制剂可能通过其免疫调节作用,而对急性胰腺炎有普遍治疗效果.为证实这一假说,本研究通过动物实验观察了常用的免疫抑制剂氟尿嘧啶,甲泼尼龙,环磷酰胺和氨甲喋呤对大鼠急性胰腺炎的炎症性细胞因子和抗炎症细胞因子的抑制作用及其治疗效果. 1.材料和方法:(1)动物:10~12周龄雄性SD大鼠,体重200~250 g,由华西医科大学动物中心提供.(2)急性胰腺炎模型和细胞因子检测:SD大鼠,共分6组,实验前16 h禁食不禁水.1组:正常对照组(n=6).2组:采用5%水合氯醛腹腔麻醉,开腹胰胆管注射5%牛磺胆酸钠0.6 ml/kg.制成胰腺炎模型;不治疗(n=8).余下各组在胰腺炎诱导成功后0.5 h分别经阴茎背静脉注射氟尿嘧啶40 mg/kg(3组n=6);甲泼尼龙30 mg/kg(4组n=6);环磷酰胺20 mg/kg(5组n=6);氨甲碟啶1.2 mg/kg(6组n=6),所有动物术后皮下输液6ml/kg-1@h-1).24 h后处死动物;抽血采用Bioassay法测定血TNF-α,IL-1,IL-6水平;采用标准商用试剂盒ELISA法测定血IL-10,TGF-β水平及胰淀粉酶,胰腺湿重.
