Humoral antibodies against skin allografts.

Using the collodion agglutination method the authors studied antibody formation against skin allografts in severely burned patients. They succeeded in detecting antibodies which start appearing on the third day following transplantation at the earliest. Later their titers increase reaching the maximum a few days before first signs of graft rejection. High titers persist for relatively long periods after graft rejection. Antibodies were not detected if the grafts were taken from an identical twin. In this case the grafts were not rejected. These results could be used for the determination of the optimal time for debridement of adhering allografts before the onset of rejection.
