HISTOCOMPATIBILITY STUDIES IN A CLOSELY BRED COLONY OF DOGS

Abstract
The establishment of a closely bred colony of beagles with known leukocyte group phenotypes has permitted an assessment of the role of leukocyte group antigens in conditioning the survival of renal allografts in the unmodified host. 22 kidney transplants obtained from leukocyte group-compatible donors were accorded a mean survival time of 25.5 days, as compared with 13.1 days for 27 transplants obtained from incompatible donors. Donor-recipient coefficients of correlation and Swisher erythrocyte group incompatibilities did not appear to affect the observed results. The mean survival time of 21 renal allografts performed in randomly selected mongrel dogs was 9.5 days.
