ABSTRACT
The success or failure of any transplanted organ is direcdy associated with the recipient s response to the allografts and with changes within the allografts that promote such a response. Although it has been recog nized that antibodies and complement as well as cellular infiltrates are key elements associ ated with the success or failure of the allografts, it has also been recognized that grafts lacking immunologic responses have similar degrees of success or failure.1
