[Blood coagulating and anticoagulant properties of the tissues in experimental chronic alcoholism in albino rats].

A study was made of thromboplastin, antiheparin and antithrombin activity of the brain, heart and liver tissues of rats in experimental chronic alcoholization. Appreciable changes in the tissue factors of coagulation according to the dyscoagulemia type depending on the duration and gravity of alcoholic intoxication may aggravate hemostatic disorders.

[Immunosuppressive properties of the influenza virus].

In experimental influenza infection in mice, inhibition of generation of antibody and antibody-producing cells was observed against reduced activity of T-suppressors and activation of T-helpers. These data indicate that the immunosuppressive effect of influenza virus is associated with inhibition of some other elements in the lymphocyte T-system rather than T-helpers.

[Patterns in the change in the number of carriers and epizootic activity in a floodplain local natural focus of tularemia in Voronezh Province].

Prolonged study of the population of Arvicola terrestris L. in connection with tularemia epizootic among these animals showed this animal to serve as the principal carrier of tularemia infection in the Povorinsk natural focus. Epizootics proved to originate with a definite threshold count of Arvicola terrestris L.

[Surgical plastic materials with prolonged antibacterial activity].

Sulphonation and further treatment with geomycine of surgical plastic articles (arterial prostheses, surgical threads) allowed to receive materials with prolongated surface antibacterial activity. The results of experiments on 200 animals proved the modified threads and prostheses to protect the bacteriostatic effect in surgical wounds within 2 to 10 days' period. The healing of implants was uncomplicated.
