1. After the transfusion by fresh hemolyzed blood the animal become feverish, but after that with stored hemolyzed blood almost no fever is seen. 2. In case of transfusion with fresh hemolyzed blood, a descending of blood pressure is found but in that with stored hemolyzed blood it is not found. 3. After transfusion with fresh or stored blood a temporary decrease of nonprotein nitrogen is seen. It is especially marked after that with stored hemolyzed blood. 4. After transfusion with fresh hemolyzed blood the serum A/G decreases but γ-globulin increases. After that with stored hemolyzed blood the latter decreases rather weakly. 5. In the histological findings aftes transfusion with fresh or stored hemolyzed blood, in the kidney nephrosis, in the lever degeneration and in the spleen and lung a blood stagination are seen. The changes after transfusion with stored blood are much stronger. 6. From the results mentioned above, after transfusion with fresh hemolyzed blood the symptomatic effects as fever, drop of blood pressure are strong but ill effects upon nonprotein nitrogen and histological findings are weak. On this point the stored hemolyzed blood has ill effects stronger than that of the fresh hemolyzed blood.
