大量资料表明,惰性宫内节育器引致子宫中纤维蛋白溶解活性增加,而后者则与月经失血量增加有关。本工作即采用提取和定量的方法研究了子宫组织中纤维蛋白溶酶元激活物的含量,特别关注在放置宫内节育器附近,远离部位及对照子宫组织中该激活物浓度的差异。从22例使用宫内节育器妇女行子宫切除术后得到子宫组织。所带节育器为立普氏环 D 或大的 Saf-T 圈,最少放置一年,最长为八年。手术前至少一年未用激素或避孕药。在结扎子宫血管供应的15分
A large number of data show that inert IUD caused uterine fibrinolytic activity increased, while the latter is associated with increased menstrual blood loss. This work is to use extraction and quantitative methods to study the content of plasminogen activator in uterine tissue, with particular attention to the difference in concentration of activators in the vicinity of IUD, away from the site and control uterus. Uterine tissue was obtained from 22 women who underwent hysterectomy with an IUD. The IUD is a Laplace ring D or a large Saf-T ring, for a minimum of one year up to a maximum of eight years. At least one year before surgery without hormones or contraceptives. 15 minutes to ligate uterine vascular supply
