title: Comparison between two radiation protective substances in irradiated mice. Effect on splenic haemopoiesis.
abstract: The radiation protective action of 2,2'-Dithiobis(N-[(1-adamantyl)-methyl]-acetamidine)-dihyrochloride (S-75) and cysteamine was compared in splenectomized and non-splenectomized mice. Cysteamine was found to have better and more general protection properties. Several indications of a specific effect of S-75 on the spleen were observed. It is suggested that the protection properties of S-75 should be tested in another laboratory animal not having such a marked splenic haemopoiesis as the mouse.
