The author, as a link in the serial study on improvement of medullary hematopoiesis by so-called bone-marrow substance, tried to investigate both effects and functions of parenteral administration of rabbit's red bone-marrow autolysate (called simply as "bone-marrow extract" hereafter); so that, having injected its certain amount into normal rabbit's abdominal cavity, the author inspected its hourly effect on peripheral blood picture as well as on blood picture of V. nuturitica femoralis, and also took observations of certain changes that occurred to intramedullary circulation. As a result, the author discovered that: 1) the biphasic blood cell increase was induced in both cases of single and successive injection alike; 2) in its secondary blood cell increase, the increase was more remarkable in case of successive, than in case of single, injection; 3) above all, an increase of reticulocytes, a comparative increase of pseudoeosinocytes, and a left shift of leucocytes, were remarkably induced. Moreover, in case of the primary blood cell increase, an expansion of medullary nutric vessels, a marked blood cell increase in nutric veinal blood, and a comparative increase of pseudoeosinocytes --- i. e. a liberation of accumulated blood cells within bone-marrow --- were brought about; and further, the blood stream within bone-marrow under the two phases of blood cell increase was noticed to be remarkably stimulated, as compared with the case in normal rabbit. From the above results, it may roughly be said that, in case the bone-marrow extract should be intraabdominally injected, a biphasic blood cell increase occures in both cases of single and successive injection, the latter being more powerful in stimulating medullary hematopoiesis; and that the primary blood cell increase is caused by the mobilization as well as the liberation of accumulated blood cells which is due to the stimulation to blood stream within bone-marrow, while the secondary blood cell increase owes much to the hematopoietic function of bone-marrow which is originated in the continuance of stimulation to blood stream within bone-marrow.
