[Hematopoiesis in rats with destroyed posterior hypothalamic nuclei using the absolute number of bone marrow cells as an index].

The effect of bilateral electrocoagulation of mammilary body nuclei on the total count of bone marrow cells was studied in experiments on rats. The destruction of hypothalamus posterior nuclei resulted in erythropoiesis inhibition. A decrease in the mitotic number and in the erythroid cell total count was accompanied by granulocytopoiesis stimulation. There was a rise in the proliferative activity and in the total count of immature granulocytes in bone marrow of the rats.
