[Importance of replacing the support medium for viral interferonogenesis in tissue culture].
Interferonogenesis in the cells of chick embryos induced by strain Lee of influenza B virus was studied. The levels of interferon production with and without changing the medium before the cell inoculation with the interferonogens were compared. It was shown that preliminary changing of the medium resulted in a statistically reliable increase in production of interferon as compared to that without the medium changing. It was found that the increase in the synthesis of interferon under the conditions of the maintaining medium changing was accompanied by an increase in the levels of synthesis of the cellular protein and RNA determined by incorporation of C14-leucine and H3-uridine into the acid insoluble fraction of the cells. It is concluded that metabolic changes in the cells at the moment of interferonogenesis induction due to the maintaining medium changing should be considered in estimation of the experiments on the mechanism of the virus induced interferonogenesis in the tissue culture.
