[Stimulant effect of antilymphocytic serum on early stages of hematopoietic recovery in the spleen of radiation chimeras].

Experiments conducted on 236 BALB/c mice were aimed at the study of the effect of the antilymphocytic serum on the hemopoiesis recovery in the spleen of the radiation chimeras, since the antilymphocytic serum was known to increase the number of macroscopic hemopoietic colonies. This increase was found to be due to the intensification of the first hemopoietic recovery stage, i.e. to the acceleration and intensification of the reticular cell activation in the recepient's spleen.
