本文研究了73名健康经产非孕妇女在放置宫内节育器(IUD)前、置IUD时及置IUD一月后宫腔内压(IUP)和宫腔液中6-keto-PGF_(1α)、TXB_2的含量。结果:1.非孕妇女在月经周期第8～14天的IUP为1.91±1.18KPa(95%可信限:1.64,2.18KPa),频率为2.68±1.25次/分;2.放置IUD对IUP没有长期的明显影响(P>0.05);置IUD前IUP较高者容易脱落(P<0.05);3.宫颈松驰度及孕/产次的差别和置不同类型的宫型器及环形器均不对IUP产生明显影响(P>0.05,P>0.1);4.放置IUD后,可使宫腔液中TXB_2和6-keto-PGF_(1α)含量明显增高,但两者的比值(P/T值)无明显变化;IUP与P/T值呈直线负相关(r=-0.264,P<0.05)。
In this study, 73 healthy non-pregnant women with non-pregnant women were treated with intrauterine pressure (IUP) and intrauterine fluid 6-keto-PGF_ (1α) , TXB_2 content. IUP for non-pregnant women on the 8th to 14th day of the menstrual cycle was 1.91 ± 1.18KPa (95% confidence limit: 1.64,2.18KPa) at a frequency of 2.68 ± 1.25 beats / min; 2. Place IUD on IUP (P> 0.05). The higher IUP before IUD was easy to fall off (P <0.05). 3. The difference of cervical relaxation rate and pregnancy / birth rate and different types of uterine organ and circulator (P> 0.05, P> 0.1). 4. After IUD placement, the content of TXB2 and 6-keto-PGF1α in uterine fluid increased obviously, but the ratio of P / T value). There was a linear negative correlation between IUP and P / T (r = -0.264, P <0.05).
