title: [Biological activity of calf spleen extracts containing a DNAase I inhibitor during irradiation].
abstract: The purified calf spleen extract (I fraction CM-cellulose), possessing a highly active natural inhibitor of DNAase I, increases the survival rate of gamma-irradiated animals as opposed to irradiated controls. A possible role of DNAase I inhibitor in the radioprotective effect is discussed.
