血型是人体的一种遗传性状,是由父母双方各给胎儿一个基因,组成胎儿的血型基因。因此,胎儿的血型与母亲血型不尽相同,就有发生母子缸型不合的可能。ABO血型不合者,除发生新生儿溶血病外,还在胚胎早期,因胎儿组织液内含有血型物质,可与来自母体的抗体结合破坏胚胎脏器的分化和发育,导致胎儿各系统器官发育不全,各 Blood type is a genetic trait of the human body, by both parents give each one of the fetus a gene, the fetus blood group genes. Therefore, the fetus’s blood type and the mother’s blood type is not the same, there may be a mother-child cylinder type may not fit. ABO blood group incompatibility, in addition to the occurrence of neonatal hemolytic disease, but also early in the embryo, due to the fetal tissue fluid containing blood type substances, can be combined with antibodies from the maternal body to destroy the differentiation and development of embryonic organs, leading to fetal fetal system hypoplasia, each
