Abstract: | Fraction F1 with a MW of 5.10(3)-5.10(4), which had been isolated from the blood serum of blood donors as controls and patients at the terminal stage of chronic kidney insufficiency, specifically inhibited the erythropoiesis of test animals at the stage sensitive to erythropoietin and morphologically distinguishable cells of the bone-marrow. In uremia, protein concentration was twice higher in comparison to the normal one. The inhibiting effect of fraction F1 from the serum of patients is caused by the enlargement of level of physiological inhibitors and unspecific toxins of the cell proliferation. Those data characterising the factor detected in the fraction F1 of normal serum together with the erythrocytic chalon are discussed. |
