  • Title: The effect of splenectomy on bone marrow haematopoiesis in mice.
    Author: Fiala J, Viktora L.
    Journal: Physiol Bohemoslov; 1976; 25(5):419-26. PubMed ID: 162622.
    Abstract:
    Splenectomy was performed in strain H mice. Erythrocyte macrocytosis and an increase in the reticulocyte, leucocyte and thrombocyte count were found in the peripheral blood of splenectomized animals; only the erythrocyte count fell in the first 3 weeks after splenectomy. Changes in the myelogram during the first weeks after splenectomy were characterized by an increase in the proportion of cells of the erythrocytic and lymphocytic series. The stem cell count in the bone marrow (determined after Till and McCulloch) was slightly elevated on the 8th day after splenectomy, but in subsequent weeks was rather lower than the control group values. Whatever the post-splenectomy interval at which bone marrow was taken from splenectomized mice, there was no significant difference in the transplantation effect of bone marrow cells on white and thrombocyte haematopoiesis. Bone marrow transplantation was found have a stimulant effect only on the reticulocyte count and the sooner bone marrow was collected after splenectomy, the more pronounced the effect. Changes in the myelogram and splenogram of irradiated mice to which the bone marrow cells of splenectomized mice had been transplanted were relatively small.
