title: Influence of age and K, Mg aspartate (Cardilan) on murine haemopoiesis.
abstract: We have studied the effect of age as well as the effect of short-term and long-term intake of K and Mg salts of aspartic acid (Cardilan) on haemopoiesis in ICR mice strain. The cellularity of the bone marrow does not change with aging, but the number of granulocyte-macrophage colony-forming cells (GM-CFC) and also the number of spleen colony-forming units (CFU-S) and erythroid burst-forming units (BFU-E) in two-year-old mice increased in the bone marrow. In two-year-old mice the number of leukocytes decreased in the peripheral blood with aging, mainly as a result of a decrease in mononuclear cells. Short-term drinking (STD) of Cardilan caused increased numbers of CFU-S and BFU-E in bone marrow and increased numbers of reticulocytes in the peripheral blood of one-year old animals (STD/12 months old). In the oldest mice (STD/24) increased weight and cellularity of the spleen and rapid increase of leukocytes and reticulocytes in the peripheral blood was recorded. After long-term drinking (LTD) of Cardilan the number of spleen GM-CFC rose markedly in one-year-old mice (LTD/12) and in two-year-old mice (LTD/24) the number of reticulocytes in the peripheral blood rose. Our results indicate that K and Mg salts of aspartic acid influence erythropoietic activity most widely.
