The levels of CD56 +CD3 - NK cells and their CD56 +CD16 -, CD56 +CD16 + subsets in decidua were detected using two color flow cytometric analysis.The NK cells activity was measured by a chromium 51( 51 Cr) release cytotoxicity assay,with K562 human myeloid leukaemia cells as targets.Results:Compared with control group, the proportion of CD56 +CD3 - NK cells in decidual mononuclear cells(DMC) of UHA patients had no difference, but the CD56 +CD16 - NK cell subset decreased and the CD56 +CD16 + subset increased significantly (P<0.05). The decidual NK cells activities of UHA patients were higher than those of normal controls (P<0.05).Conclusions:NK cell is predominant lymphocyte in normal decidua and plays an important role in maintaining successful pregnancy. Abnormally raised activity and disbalanced CD56 +CD16 +, CD56 +CD16 - subsets of decidual NK cell are associated with UHA and may play a role in reproductive failure.展开更多
目的:探讨淋巴细胞免疫治疗习惯性流产及不明原因流产的疗效及护理。方法:对习惯性流产及不明原因流产患者,采用丈夫或第三者(男性)健康肘静脉血20 m l分离淋巴细胞行主动免疫治疗,并设单纯静脉滴注丙种球蛋白治疗者作对照组,观察两组...目的:探讨淋巴细胞免疫治疗习惯性流产及不明原因流产的疗效及护理。方法:对习惯性流产及不明原因流产患者,采用丈夫或第三者(男性)健康肘静脉血20 m l分离淋巴细胞行主动免疫治疗,并设单纯静脉滴注丙种球蛋白治疗者作对照组,观察两组患者妊娠成功率、婴幼儿生长情况及经济费用情况。结果:两组治疗效果及经济费用比较差异具有显著性(P<0.01),两组婴幼儿生长情况比较无显著性差异(P>0.05)。结论:淋巴细胞主动免疫疗法可提高患者免疫反应性,有提高妊娠率,降低经济费用,对婴幼儿生长无影响等优点,不失为治疗习惯性流产的一种简单好方法。展开更多
