摘要: 目的 从细胞水平观察地塞米松对感染柯萨奇(CoxB-2)病毒的人胚心肌细胞的作用,从而对病毒性心肌炎患者应用激素治疗的问题作出评价。方法 采用培养的人胚心肌细胞接种CoxB-2病毒,观察细胞生长、搏动情况及超微结构,测定心肌细胞释放的LDH活性。结果 地塞米松治疗组的心肌细胞搏动较感染组者维持时间长,心肌细胞病变发展亦较缓慢,且LDH值明显低于感染组。结论 地塞米松对感染CoxB-2病毒的人胚心肌细胞有明显的保护作用,提示临床上重症病毒性心肌炎,特别是早期阶段,应用激素有一定的治疗意义。

Abstract: Aim Theeffects of Dexamethasone(Dex) on human fetal heart cells intected by Coxsackie B-2 virus were studiedinvitra.Methods Thelevels of LDH were de termined, thecytopathic effect (CPE), thebeat ing of heart cells and electromicroscopic findings were observedin cultured heart cells infected by coxsackie B-2 virus.Results LDH levels were much low er in theDex-treatedinfected group than those in theinfected group.Less CPE could be foundin theDex-treatedinfected group, while theCPE appeared rapidly in theinfected group atthesameintervals.Atthefi rst day, themyocytes showed nearly normalul trastructure in theDex-treatedinfected group, how ever, themi tochondrial cristae were unclear in theinfected group.Conclusion Dexamethasone exerted someprotective Effects on cultured human fetal heart cells infected by Coxsackie B-2 vi rus.
