This is due to the ,physiologic antagonism of blood and tissue that exists between different indi-viduals. Homoplastic transplantation is more successful when there is a bloodrelationship between the two individuals than when they are entirely unrelated,for in the former case the physiologic antagonism is less intense. The successof an ovarian graft depends to a certain extent on the length of time betweenextirpation and transplantation. Thus, a graft that is made immediately is RELATIONSHIP OF GYNECOLOGY TO THE GENERAL ORGANISM 61. Fig. 21.—Ovarian Transplant in Horn of Uterus after Six Years. 1, New vessels that have formed between the uterine and ovarian tissues. 2, Junction ofuterine and ovarian tissues. 3, Corpus albicans. 4, Atretic follicle. Note that the surface of the ovarian graft did not become adherent to the surrounding tissues. History of the case: Operation May 3, 1910. Double salpingectomy, with transplantation ofovarian tissue in each horn of the uterus. Both ovaries preserved. Four years later patient re-ported that she had a miscarriage at three months. Statement corroborated by attending phys-ician, but no fetal tissue preserved for confirmation. Operation June 6, 1916. Hystero-oophorectomy for ovarian cyst and pelvic adhesions. Bothoperations performed by the author at the Free Hospital for Women, Brookline. 62 GYNECOLOGY more favorable than one where the gland is preserved for a time in cold storageor where it has been treated with some chemical, such as iodin, or heated f
