骨髓移植供、受体的HLA相合程度是决定移植成败的关键因素之一。HLADR4亚型在各人种中的频率均较高,且与骨髓移植后GVHD(graftversushostdisease,移植物抗宿主病)的发生有关〔13〕。为探讨HLADR4基因亚型在骨髓移植
Bone marrow transplantation donor and recipient HLA matching degree is one of the key factors in determining the success or failure of transplantation. HLA DR4 subtypes in all species frequency are higher, and bone marrow transplantation after GVHD (graft versus host disease, graft-versus-host disease) of the occurrence of 〔〕 1-3. To investigate HLA DR4 subtypes in bone marrow transplantation
