采用ＥＬＩＳＡ间接法检测了健康孕妇、妇科肿瘤和妇科炎症患者宫颈粘液中抗精浆免疫抑制物抗体（ＳＰＩＭ－Ａｂ）含量。结果表明，与对照组比较，孕妇、宫颈癌、阴道炎、宫颈炎和子宫内膜炎患者宫颈粘液ＳＰＩＭ水平均有明显下降。提示：妊娠期间低水平ＳＰＩＭ－Ａｂ有利于ＳＰＩＭ保护孕卵着床和发育，但ＳＰＩＭ－Ａｂ水平过低，易于发生生殖道感染和肿瘤。 The contents of anti-seminal plasma immunosuppressive antibody (SPIM-Ab) in cervical mucus of healthy pregnant women, gynecologic tumors and gynecological inflammation patients were detected by ELISA indirect method. The results showed that compared with the control group, cervical mucus SPIM levels in pregnant women, cervical cancer, vaginitis, cervicitis and endometritis were significantly decreased. Tip: Low levels of SPIM-Ab during pregnancy are beneficial for SPIM to protect the implantation and development of the pregnant egg, but the level of SPIM-Ab is too low to cause genital tract infections and tumors.
