[Comparative study on tissue morphology and vascular changes of skin xenografts, allografts and autografts after transplantation].

In this study, the tissue morphology and the vascular changes of skin xenografts from the rats to the rabbits were compared with that of skin allografts and autografts simultaneously transplanted to the same recipient by the use of histological examination and dye injection. The results suggested that the xenografts were incapable of becoming vascularized, and exhibited necrosis on the third day, while early vascularization was demonstrated in the allografts and autografts. The xenografts underwent a course of "white graft rejection", which probably contributed to rejection.
