Frogs of the species Rana esculenta were irradiated with a dose of 10,000 r and were then kept at room temperature or at a low temperature, Control frogs kept at room temperature died within 17 days after irradiation. Of frogs kept at 4 deg C only 35% died within 60 days after irradiation while the rest died within 12 days when transferred to room temperature. The average weight of the spleens of frogs kept in the cold after irradiation was almost twice that of the spleens of frogs kept at room temperature. Histological examination showed that the reticular cells of the spleens of frogs kept in the cold temporarily maintained the capacity for differentiation into blast cells, which afterwards underwent secondary disintegration. The authors assume that prolonged survival at a low temperature is not due to a lower degree of post-irradiation destruction, but to the maintenance of some degree of ribonucleic acid and protein metabolism.
