本文用家兔和小鼠对雌性生殖管的屏障进行了研究。所得结果表明:①输卵管及输卵管伞存在血-输卵管腔及血-输卵管伞腔屏障;②其结构可能为固有膜和上皮下方的基膜以及上皮细胞间的紧密连接;③此屏障与血-卵屏障,血-子宫腔屏障和子宫-血屏障共同形成一个统一的微环境,它对排卵,卵细胞的受精和受精卵的继续发育,免受有害因子的影响,有着重要的生理意义。 In this paper, the barrier of female reproductive tubes was studied in rabbits and mice. The results showed that: ① oviduct and oviduct umbrella blood - tubal cavity and blood - fallopian tube umbrella barrier; ② Its structure may be the underlying membrane and the epithelial basement membrane and epithelial cells in close contact; ③ The barrier and blood - egg Barrier, blood - uterine cavity barrier and uterine - blood barrier together form a unified microenvironment, which has important physiological significance for ovulation, fertilization of oocytes and the continued development of fertilized eggs from harmful factors.
