title: [Study of the biological activity of spleen extracts containing inhibitor of DNA-ase I].
abstract: Fractions of calf spleen extracts possessing the increased potency to inhibit the activity of DNase 1 were obtained by chromatography on columns with Sephadex G-200 and CM-cellulose. The fractions containing the most powerful inhibitor of DNase 1 increased the survival rate of sublethally irradiated mice and hamsters. A possible role of the DNase 1 inhibitor in cure effects is discussed.
