摘要 目的 探讨γ 干扰素 (γ IFN)、一氧化氮 (NO)的表达在实验性病毒性心肌炎中的作用。方法 BALB/C鼠 6 0只 ,随机选 15只作正常对照 (A组 ) ,另 45只腹腔注射柯萨奇病毒B3 亲心肌株 (CVB3 m)后分 3组 ,病毒对照组 (B组 )、小剂量用药组 (C组 )、大剂量用药组 (D组 ) ,C、D组均在感染病毒后d4腹腔注射甲基强的松龙 (30mg/kg ,6 0mg/kg) ,连用 3d。均在接种病毒后 7、14、2 1d留取血液、心肌标本 ,分别进行血清γ IFN、心肌匀浆NO及心肌病理检查。结果  1.γ IFN、NO过分表达可致心肌病理损伤。 2 .C组小鼠γ IFN、NO水平较B组略有下降 ,而D组γ IFN、NO远远低于B、C组水平 ,动物死亡率大大增加。结论 γ IFN、NO在病毒性心肌炎发病中起重要作用 ,过高或过低水平均不利于动物抗病毒损伤 ,适当运用激素可以限制过高细胞因子表达 。
