Chemiluminescence of irradiated animal blood plasma.

Spontaneous and induced chemiluminescence of rat blood plasma following irradiation of the animals with fast neurons was studied. Dynamics of the luminescence reflected the degree of radiation injury and an oscillatory response of blood chemiluminescent effect was observed.

Effect of influenza virus on the immune responsiveness of animals.

Infection of mice with A/Hong Kong/1/68 (H3N2) and A/PR8/34 (H0N1) influenza virus strains resulted in a significant inhibition of the formation of antibody-producing cells in response to administration of sheep erythrocytes and a reduced capacity of spleen cells to induce "graft-versus-host" reaction. The immunosuppression caused by influenza infection was observed for a long period of time post infection (3--6 months). The extent of inhibition of antibody production depended on the dose of virus, route of inoculation, the sequence of infection and immunization and the internal between them.
