妊娠成功和维持,一般认为需要各种免疫抑制机构,阻止对妊卵的排斥反应。Morton等用同种移植中免疫抑制状态的评价方法——玫瑰花环形成抑制试验,观察到受精后早期的血清中出现免疫抑制因子,命名为超早孕因子(EPF),对其一系列研究的结果证明EPF具有免疫抑制作用。作为早期妊娠因子在妊娠维持机理中发挥作用的EPF引起人们关注。作者用抗人T淋巴细胞单克隆抗体进行淋巴细胞玫瑰花环形成抑制试验,以研究妊娠尿中的 Pregnancy success and maintenance, generally considered the need for a variety of immunosuppressive institutions to prevent rejection of the pregnancy egg reaction. Morton and other methods of allogeneic immunosuppressive evaluation of the state - rosette formation inhibition test, observed in the early post-fertilization serum immunosuppressive factor appears, named for early pregnancy factor (EPF), a series of its findings EPF proved to have immunosuppressive effects. EPF, which plays a role in the maintenance of pregnancy mechanism as an early pregnancy factor, has drawn people’s attention. The authors used a monoclonal anti-human T lymphocyte lymphocyte rosette inhibition test to study the urine of pregnancy
