Two cadaver kidneys were preserved by the perfusion method with AB cryoprecipitated plasma which contained antidonor lymphocytotoxic antibody. The kidneys were transplanted subsequently and no demonstrable immunologic damage to the kidneys was observed in the preservation and post-transplantation periods. In one patient renal function was immediate, and function has remained satisfactory in the 3 month follow-up period. The other patient had an initial period (2 weeks) of acute tubular necrosis, but renal function became satisfactory and the patient's condition has remained stable in the 3 month follow-up period. The significance of antidonor lymphocytotoxic antibody in the plasma perfusate on subsequent kidney function has been discussed.

Lymphoid cells present in spleen and lymph nodes of hyperimmune rabbits were found to be differentiated with respect to the class of immunoglobulin heavy chain which they contained. The relative proportions of cells containing the various heavy chains were as follows: alpha-chain (5 to 8%), micro-chain (14 to 21%), and gamma-chain (71 to 81%). The allotypic markers Aa1 and Aa2, found on heavy chains, were also found to be separately localized in cells of Aa(1)/Aa(2) heterozygous rabbits. The ratio of cells in spleen and lymph nodes containing the Aa1 marker to those containing the Aa2 marker varied with individual rabbits; the range was 53 to 88% Aa1 versus 12 to 47% Aa2.
