[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.

[Etiopathogenetic approach to the treatment of viral-bacterial pneumonias].

The efficacy of aerosols of leukocytal interferon used in complex with antibacterial and other medicamentous agents was studied during influenza epidemic in 1975 due to Port-Chalmers virus of influenza A with increased numbers of viral-bacterial pneumonia. The viral-sta-phylococcal etiology of the infection was confirmed in 80 per cent of the cases under stationary conditions. Various microorganism and most often Staph aureus were isolated in addition to the viruses from the patient's sputum and washings and their antibioticograms were determined. The studies showed that the complex treatment of the patients with virologically and serologically confirmed diagnosis of the disease resulted in decreased duration of the disease, less pronounced intoxication and more rapid resorption of the changes in the lung tissue.

[Distribution of exogenous interferon in experimental animals following intratracheal administration].

The distribution of homologous and heterologous interferon in rabbits after intratracheal administration was studied. The content of interferon in the lung tissue decreased 1 hour after injection. At 3 hours the interferon concentration in the lungs in some animals decreased 2-10-fold as compared with the initial. A considerable reduction in interferon content in the lungs was observed 24 hours post-injection. In the blood serum interferon was found in low titers 1, 3 and 6 hours after intratracheal injection. On the contrary, the amount of interferon in the urine increased beginning at 3-6 hours after injection and up to 24-48 hours.

[Comparative study on the properties of influenza B viruses isolated in 1959-1974].

The biological properties and antigenic structure of the following influenza B virus strains were compared: Moscow/Likh/59, Moscow/106/62, Moscow/1/66, Hong Kong/5/72, Yamagata/73 and USSR/01/4. The influenza B virus strains isolated in 1972-1974 differed by hemagglutinin from those isolated in 1959-1966. The variability of hemagglutinin correlated with that of neuraminidase. Yamagata/73 virus occupied a special position both with regard to the structure of surface antigens and to some other biological properties. Therefore, the possibility of occurrence in the USSR of virus strains similar to Yamagata/73 cannot be ruled out.
