it has been demonstrated in experiments on mice ( cba x c57bl ) x f1 , thymectomized and irradiated by 800 r , with the haemopoietic system restored by bone marrow ( b-mice ) that in these animals , as compared with the controls , the changes in cellular immunity ( inhibition of natural killer cells and stimulation of individual functions of the phagocytizing cells ) are accompanied by considerable inhibition of osteogenesis .
