Results In Vero cell system,in direct virucidal and infection block experiments,fullerene C60 liposomes have induction effect on the expression of HSV-1F strain glycoprotein gC,whether it is under illumination or in lucifugal conditions,but in multiplication inhibition experiments,fullerene C60 liposomes have no effect to the expression of HSV-1F strain gC.

结果 在Vero细胞系统中，C60脂质体在直接杀灭和感染阻断的实验中，不论在光照还是在避光条件下，对HSV-1F株gC的表达均有诱导作用；但是在增殖抑制实验中，对HSV-1F株gC的表达没有影响。
