Abstract
The measurement of the oxidation rate of bone marrow is important in order to know the grade of radiation injury and the course of recovery, because the oxidation rate of the bone marrow in the guinea pig shows remarkable decrease by a single whole body X-ray irradiation and its recovery is gradual.
The subcutaneous injection of powdered young rabbits bone marrow every other day to the guinea pig which had been irradiated by X ray in doses of 300r at a time, significantly promate the recovery of oxidation in the bone marrow.
On the other hand, the injection of powdered human leucocytes shows no good effects, and the daily injection of powdered pig's bone marrow or powoered pig lymphocytes shows inhibitory action in the recovery from the acute radiation injury in the guinea pig.
