title: [Effect of synthetic polyribonucleotides on the immunological and colony-forming activity of irradiated bone marrow cells].
abstract: The experimental data are presented concerning the effect of polyribonucleotides on the immunologic and colony forming ability of bone marrow or irradiated mice. All the compounds under study exhibited a pronounced, but to a different degree, colony-forming and immunostimulating action. The comparative study of the influence of polyribonucleotides on the number of endogenous colonies and antibody-forming cells showed an inverse relationship between these parameters: The preparations exerting the most pronounced immunostimulating effect had an insignificant colony-forming action and vice versa. This is evidently indicative of the capacity of these preparations to turn the differentiation of haemopoietic stem cells towards the immunopoiesis.
