Abstract


The effects of promoting substances extracted from the liver and kidney of the rabbits irradiated with X-ray were studied on the growth of Ehrlich ascites cancer and sarcoma-180 in mice and on the mitosis of the liver and kidney cells of the normal mice. The results obtained were as follows;
1) The amount of the promoting substances from the X-ray irradiated tissues decreased markedly as compared with that of the non-irradiated tissues.
2) The experimental groups demonstrated less promoting effects on the growth of the transplantable animal tumors than that of the non-irradiated group.
3) The promoting substances extracted from the X-ray irradiated tissues exhibited less accele rating effects on the mitosis of the liver and kidney of the nomal mice than that of the non-irradiated tissues.
