Abstract
PURPOSE:To obtain the titled factor useful for hematopiesis after chemotherapy, radiotherapy or transplanting of bone marrow for cancer, by keeping human urine under alkaline condition and treating the human urine with molecular sieves. CONSTITUTION:Human urine is kept under alkaline condition and then treated with molecular sieves to afford the aimed factor. Furthermore, human urine collected from a patient suffering from a plastic anemia is preferably used as the human urine and pH is preferably kept at >=7.5. Membranes or gels of molecular sieves having about 50,000-200,000 cut molecular weight or gels (e.g. dextran or polyacrylamide derivative) are preferably used as the molecular sieves.
