Failure to Demonstrate Toxic Factors in the Serum of Irradiated Rats.

Summary Three experimental procedures were utilized to assay serum from irradiated rats for radiotoxic substances. Such toxic material was not demonstrable by these technics. These experiments do not preclude the existence of radiotoxins in the irradiated animal, but they do indicate that if radiotoxins exist, the blood is probably not their principal storehouse. If, on the other hand, the blood does figure significantly in their storage, then they are not responsible for the severe signs and symptoms resulting from acute total body exposure.
