作者研究960名孕妇的HL-A抗体和胎儿男女比率的关系。发现:初产妇中61人有HL-A抗体者其分娩的男女比率为1.82,384人无此抗体,其分娩的男女比率为0.99,两者有显著差别(P<0.05);第二胎孕妇280人中18.6%有HL-A抗体,其余无此抗体,分娩的男女比率分别为1.26和1.24;多胎产妇235人中26.8%有HL-A抗体,其余无此抗体,分娩的男女比率分别为1.10和1.54(0.4>P>0.3)。作者认为,有HL-A抗体者总的分娩男女比率更高些可能是机遇,而初产妇中有HL-A抗体者分娩的男女比率显著增高,则提供了HL-A和未鉴定的性特异组织相容系统之间相互作用的证据。作者对85例孕妇中鉴定出的123个单特异性HL-A抗体的研究发现,具有相同的特异抗体的孕妇。不论其胎次,分娩的男女比率大致相同。其中生成HL-AⅠ和Ⅱ(第一系列)抗体和HL-A5、12和13,以及TYT(第二系列)抗体者,为男性优势组,分娩的男女比率为3.9(31:8);而生成其他特异HL-
The authors studied the relationship between HL-A antibody in 960 pregnant women and the ratio of male and female fetuses. Found that: 61 primiparous women with HL-A antibody delivery rate of 1.82,384 people without this antibody, the delivery rate of 0.99 for men and women, both significantly different (P <0.05); the second pregnant women Among the 280 patients, 18.6% had HL-A antibody, the rest without this antibody, the ratio of male to female childbirth was 1.26 and 1.24, respectively. 26.8% of 235 pregnant women with multiple mothers had HL-A antibody and the rest had no such antibody. The rates of male to female childbirth were 1.10 and 1.54 (0.4> P> 0.3). The authors argue that higher rates of overall childbirth for men with and those with HL-A antibodies may be an opportunity, while the proportion of males to females who have HL-A antibodies in preterm infants is significantly higher providing HL-A and unidentified sex-specific Evidence of the interaction between the tissue compatible systems. A study of 123 monospecific HL-A antibodies identified in 85 pregnant women found that pregnant women with the same specific antibodies. Regardless of their parity, the rate of childbirth is about the same. Among them, those who produced HL-AI and II (first series) antibodies and HL-A5, 12 and 13, and TYT (second series) antibodies were the male predominance group with a ratio of 3.9 (31: 8) Generate other specific HL-
