Organ transplantation in mongrel dogs using total lymphoid irradiation (TLI).

Abstract

Although we were able to establish bone marrow chimerism in mongrel dogs using TLI at a cumulative dose of 1800 rad, it was more difficult to establish prolonged organ allograft survival in this system. We review here our experience with allogeneic heart transplantation in dogs using TLI combined with limited courses of pharmacologic immunosuppression, an approach that appears to hold considerable promise for clinical organ transplantation.
