The Influences of Salivary Gland Hormone on the Hematopoiesis of Bone Marrow (by means of bone-marrow tissue culture) Part 1. On the Bone-Marrow Tissue Culture of Normal Rabbits and Normal Persons

With the purpose to clarify the influences of salivary gland hormone on the hematopoietic function of bone marrow, especially on the leucoyte series, Parotin was added directly in the medium of bone marrow tissue culture of normal rabbits and normal persons, and following results were obtained. 1. In the bone-marrow tissue culture of normal rabbits by hangingdrop method, the tissue growth, the wandering velocity and carbon-particle phagocytosis of pseudoeosinphils were increased as compared those of the control. 2. In the bone-marrow tissue culture of normal persons by our simple method, the tissue growth, the wandering verocity and carbon-particle phagocytosis of mature neutrophils were increased as compared with those of the control. 3. In the tissue culture added Parotin, the growth and function of leucocyte was accelerated most remarkably at the 6-hour culture.
