The influence of heparin on the graft-versus-host reaction (GVHR) and the peculiarities attending the development of pregnancy in female animals which survived after the GVHR were studied. Preliminary administration of heparin to the recipients prevented their death or increased their life span. An intensification of the GVHR was noted after the administration of heparin to donors or its addition to the transplanted cells. In mice which survived after the GVHR as a result of heparin administration the intrauterine fetuses death and abortions were noted in 60-100% of cases during subsequent pregnancy (3 to 6 months after the cell transplantation). In the case of repeated pregnancies of these female animal pathology of pregnancy was less frequent; however, some of the offspring displayed the rant syndrome. No such disturbances of pregnancy were observed in mice given heparin alone or in those which survived after the transplantation of lymphoid cells only. The sustained pregnancy promoted the intensification of the GVHR induced in the female animals earlier after the heparin administration.
