[Enhanced activity of the protective factors in patients with suppurative surgical infection using interferon preparations].

Administration of leukocytic interferon to patients with sepsis and purulent resorptive fever resulted in a reliable increase in the indices of the host protective factors with respect to the infections. Addition of interferon to the surgical and antibacterial treatment promoted a decrease in the periods providing the clinical effect to 19.8 days against 43.8 days in the treatment without interferon.

[Effect of mouse interferons on the development of Ehrlich ascitic carcinoma].

Intraperitoneal injection of various preparations of mouse interferons (L cell tissue culture interferons, concentrated or partly purified, and also serum interferon) significantly inhibited the development of Ehrlich's ascites carcinoma in randombred mice. In view of comparatively low activity of serum interferon, the effect of normal mouse serum on the tumour development and its action on L cell tissue culture interferon was investigated. It was shown that normal mouse serum inhibits the action of L cell tissue culture interferon and promotes the development of Ehrlich's ascites carcinoma.

[Antiviral activity of preparations of RNA isolated from cells treated with interferon (messenger RNA for an antiviral protein?)].

Chick embryo cultures treated with interferon yielded a biologically active RNA which, upon inoculation into chick embryo cells, created an antiviral condition in them. The level of vesicular stomatitis virus reproduction in such cells was 2-30% of that observed in the cells treated with control RNA. The maximum activity of the experimental RNA was seen 3 hours after the treatment with interferon.

[Transfection by integrated proviruses].

Three lines of continuous mouse L cells were compared: one of them contained only its endogenic oncornavirus, another was contaminated with SV5 virus, and a third was obtained from the second line chronically infected with vesicular stomatitis virus. Experiments with transfection showed that it was possible to recover SV5 virus from the two former cultures and vesicular stomatitis virus from the latter.

[Assessment of the sensitivity of immunoprecipitation for the serodiagnosis of influenzal-bacterial pneumonias].

A comparative examination of 226 paired sera from patients with pneumonia was carried out by CFT, HI, neuraminidase activity inhibition (NI) and double immunodiffusion. A correlation of the results of agar gel precipitation and the CFT and HI tests was observed. Convalescent sera contained antibody to influenza virus ribonucleoprotein frequently, less so to its neuraminidase or hemagglutinin. The precipitation test was shown to be highly sensitive, easy to perform, and therefore should be used in examinations of sera from patients with influenza-bacterial pneumonia.

[The comparative effects of actinomycin D, imuren and hydrocortisone on interferon and antibody formation in mice].

A single dose of actinomycin-D (2.5 mg/kg body wt) reduced the interferon formation 16-fold in comparison with control; as to the antibody production - it was completely abolished. Hydrocortiosone (100 mg/kg) also diminished the interferon production 16-fold, but had no effect on the production of antibodies against the virus. The effect of hydrocortisone on the antiviral immunity was similar to that of the antilymphocytic serum, whereas the action of actinomycin-D resembled the effect of the X-ray irradiation or imuran. The data obtained were consistent with the suggestion on the heterogeneity of cells, participating in the interferon production in the organism.
