历来作为造血因于的制法,只知从贫血的动物血液和尿中去抽取。但是在抽取的原料来源上反貯藏上困难较多,收率不充分对工业生产来说是不适当的。本发明采用哺乳动物的脏器和含钙离子或镁离子的生理盐溶液在适温下匀浆,清提,过滤去固体物质,干燥滤液或从沉淀中 Has always been as a hematopoietic factor in the system of law, only learned from the anemia of blood and urine animals to extract. However, it is more difficult to reverse-store the source of the extracted raw materials, which is not suitable for industrial production. In the invention, the mammalian organism and the physiological salt solution containing calcium ion or magnesium ion are homogenized at a proper temperature, stripped, filtered to remove the solid substance, the filtrate is filtered off or precipitated from the precipitate
