Anti-influenzal action of bacterial and pancreatic RNAases was studied. It was shown in ovo that the RNAases had distinct virus inhibiting activity with respect to various strains of the grippe A virus and did not practically differ by their activity from remantadin but unlike it had inhibitory action on the grippe B virus. The anti-influenzal activity of bacterial RNAase in contrast to pancreatic one was detected not only in experiments with developing chick embryos but also in albino mice with lethal influenzal infection.

It was shown that RNAases binding to soluble dextran did not cause any significant changes in their major catalytic properties, when polymeric RNA was used as a substrate.

The inhibitory effect of the Actinomyces rimosus RNAase on the variolovaccine virus reproduction in the tissue culture cells was shown. In the experiments with the use of chick embryons and rabbits this effect was less pronounced.

The effect of the enzyme on multiplication of the viruses of vesicular stomatitis, Newcastle and cariolovaccine diseases was investigated. It was found that the enzyme was capable of suppressing reproduction of the vesicular stomatitis virus (VSV) in the culture of chick fibroblast cells.

February 1976
The immunological properties of ribonucleases from Act. rimosus were studied in comparison with RNA-ase from the cattle pancreas. The activity of anti-RNA-ase immune sera were determined by the method of specific neutralization of the effect of the above exzymes.
