[Effect of the inhibition of prostaglandin biosynthesis on the hematopoietic status of irradiated mice].

The administration to mice of preparations inhibiting prostaglandin synthesis was shown to reduce the post-irradiation cytopenia in the peripheral blood and to increase the total cellularity of the bone marrow and the yield of splenic endocolonies. When the exposed mice were injected with intact myelocaryocytes, at the background of the inhibited prostaglandin biosynthesis, the number of exogenous colonies increased.
