Nucleic acid metabolism in brain and liver of the mouse infected with Japanese Bencephalitis was investigated using the radioactive P32.The mice intracerebrally inoculated with Japanese B encephalitis virus were intraperitoneally injected with P32 48 hours and 96 hours after the inoculation of virus.A certain portion of brain and liver of the mouse was 12 hours after the injection fractionated according to Schneiders method.The P32 activities in each fraction of the infected group as well as of the not-infected control group were compared with each other.Marked increase of P32 activities in the phosphoprotein and nucleic acids fractions of brain and liver at the acme stage of infection were clearly seen in the infected group.In the liver of the infected mouse the increase in P32 activity has already been recogneized in the incubation period, that is, in so-called visceral phase of this disease.
