摘　　要：利巴韦林具有广谱抗病毒活性,对多种DNA或RNA病毒体内外都有抑制作用。本文对利巴韦林注射液的体内外抗流感病毒活性进行研究,体外实验采用细胞病变(CPE)法研究了利巴韦林注射液对流感病毒甲乙型的活性,体内实验采用小鼠模型研究了利巴韦林注射液对流感病毒A/FM/1/47(H1N1)鼠肺适应株感染小鼠的保护作用。结果显示,在体外实验中,利巴韦林注射液对所检测的7种病毒株均有显著的抑制活性;在体内实验中,利巴韦林注射液可以显著提高感染小鼠的存活率和平均生活日,显著改善感染小鼠的肺病变和肺指数。Ribavirin is a broad-spectrum inhibitor against several unrelated DNA or RNA viruses in vitro and in vivo. In this paper the in vitro and in vivo study of anti-influenza virus activity of ribavirin （RBV） injection had been reported. The in vitro antiviral activity of ribavirin injection against influenza virus A and B was studied by CPE. The in vivo protective action of ribavirin injection against influenza A/FM/1/47（H1N1） mouse adapted strain infected mouse was studied with mouse model. The results showed ribavirin injection has strong inhibitory activity against 7 virus strains tested in vitro. Ribavirin injection could significantly increase virus infected mouse survival rate and survival days and improve lung pathogen and lung index.
