Sutthiwan et al, unpublished data) and xenografts of tumor in mice8 we decided to test the immunosuppressive effects of such sera in the allografting of livers and kidneys in dogs, and subsequently to proceed with a trial of the material in the clinical renal transplant program at the Mayo Clinic. The experiments involving hepatic allografting in dogs have been reported elsewhere,9 and the purposes of this presentation are to describe the results obtained in canine renal allografting and to review the findings of a preliminary clinical trial in human beings. In animals, the sera were used as the sole means of immunosuppression; in the clinical situation, however, testing
