IFN和PDS合剂体内抗流感病毒的作用

观察了IFN与PDS合剂的体内抗病毒效果。首先排除IFN和PDS对动物的毒性作用 ,再以不同剂量的单剂和合剂给小鼠用药。用流感强毒株对小鼠进行攻击 ,同时以利巴韦林和正常小鼠作为对照。通过对动物死亡率、肺部病变的病理组织学检查结果进行比较 ,合剂组效果明显好于单剂组 ,且有剂量效应关系。上述结果表明 ,IFN和PDS合剂可明显减轻流感病毒感染过程中的肺组织病变 ,可用于流行性感冒的治疗。

The Effect of IFN-PDS against Influenza Virusin vivo

Antiviral effect in vivo of the compound of IFN and PDS was observed in this study. At first the toxicity of IFN-PDS compound to mice was excluded and then the animals were administrated with different doses of IFN, PDS and PDS-IFN compound, respectively. The strong virulent strain of influenza virus was applied to attack the mice, and in the meantime the ribavirin-taken mice and normal mice were used as the controls. Compare to the mortality and the lesions in lung by histopathological examination among the different animal groups, the mice that given with PDS-IFN compound showed higher antiviral effect with dose-dependent pattern than the other groups. The results of this study indicate that PDS-IFN compound can significantly decrease lung lesions during influenza virus infection and this compound can be used as an efficient drug to cure influenza.;
