In the last decade, remarkable advances have been made in bone marrow transplantation (BMT), which is now becoming a powerful tool in the treatment of diseases such as leukemia, aplastic anemia, and congenital immunodeficiency. In animal experiments, it has been found that BMT can be used to treat not only systemic autoimmune diseases but also organ-specific autoimmune diseases. In humans, it has recently been shown that rheumatoid arthritis, ulcerative colitis, and Crohn's disease can be successfully treated after BMT. This volume contains new information on how to prevent graft rejection, how T cell functions can be completely restored, and how concomitant BMT can prevent the rejection of organ allografts without the use of immunosuppressive agents. BMT will become an increasingly useful and powerful treatment for various currently intractable diseases, and this book will contribute by providing details of the latest research in the field.

Bone marrow Baum (4), using a larger mammal, the dog, transplantation, which has a history of only demonstrated that injecting autologous marrow 30 to 40 years, permits this process, since post irradiation would protect lethally some of the early investigators are still with irradiated animals (see Table). Certainly, us. For example, over the past 15 years, we protection was obtained from the cellular have had three symposia in honor of Egon constituents of the bone marrow. Lorenz. As we all know, the team of Lorenz, We undertook to test on dogs the Uphoff and Congdon was involved in the first hypothesis of Gengozian and Makinodum (5) that successful transplantation of syngeneic and increasing the radiation dose will increase allogeneic bone marrow into irradiated immunologic tolerance for allogeneic implants.
