title: Immunology of intermingled skin grafts in rats: preliminary results.
abstract: Successful treatment of severely burned patients with the Chinese method of intermingled skin grafting has raised questions concerning the pathophysiological and immunological mechanisms which allow the survival of mixed allogeneic and autologous tissue. In creating a rat model and measuring systemic immunological status by means of mixed lymphocyte reactions (MLR) and histology, we found comparable levels of sensitization in intermingled and allografted rats; however, allografts were rejected and intermingled graft survival was significantly prolonged. We interpret our results to indicate that the survival of intermingled grafts is dependent upon an as yet undefined local protective effect exerted by the presence of auto-skin islands in the allotypic portion of intermingled grafts.
