[The effect of erythrocyte polypeptides on the erythron system in experimental anemia]

The paper reports the action of the polypeptide preparation made of red cells on erythron system in rat toxic anemia. These polypeptides proved more effective as to erythropoiesis stimulation in phenylhydrasine anemia than vitamin B12 or lek. Red cell polypeptides are considered possible regulators of erythropoiesis.
