Ribonuclease is a highly active inhibitor of vaccinia virus multiplication in vitro in the chorioallantoic membrane removed from embryonated chicken eggs. It is also a highly active inhibitor of pock formation by vaccinia and herpes simplex viruses on the chorioallantoic membrane in vivo. Marked inhibitory effects were obtained with 12.5 microg. of RNase. However, complete inhibition was not obtained with several hundred micrograms of the enzyme. RNase caused no inactivation of the infectivity of vaccinia virus particles but it had a marked inhibitory effect on multiplication of this virus when administered many hours after infection of host cells had occurred. RNase also failed to inactivate the infectivity of herpes simplex virus particles. The results obtained indicate that ribonucleic acid is necessary for the multiplication of two DNA-containing viruses; i.e., vaccinia and herpes simplex.
核糖核酸酶是痘苗病毒在从受精鸡蛋取出的绒毛尿囊膜上进行体外增殖的一种高效活性抑制剂。它也是痘苗病毒和单纯疱疹病毒在体内绒毛尿囊膜上形成痘疱的高效活性抑制剂。12.5微克核糖核酸酶产生了显著的抑制作用。然而,几百微克这种酶并未产生完全抑制作用。核糖核酸酶不会使痘苗病毒颗粒的感染性失活,但在宿主细胞感染数小时后给药时,它对该病毒的增殖有显著抑制作用。核糖核酸酶也未能使单纯疱疹病毒颗粒的感染性失活。所得结果表明,核糖核酸对于两种含DNA病毒即痘苗病毒和单纯疱疹病毒的增殖是必需的。
