Comparison of Protective Effects of Hind-leg Shielding and Isologous Bone-marrow Injection in X-irradiated Rats

Abstract
The effect of hind-leg shielding and of the intravenous injection of isologous bone marrow on the radiation response of the young rat has been studied by means of blood counts and by measurement of the uptake of radioactive iron in various tissues. The mechanism of action of the two protective procedures is discussed, particularly with regard to the relative importance of reduced platelet fall and of compensatory erythropoiesis.
