为了探讨放置宫内节育器与不放器妇女宫腔局部环境的变化,本文对35例放器10个月的妇女于月经中期(月经周期的第10～14天)测定了宫颈粘液的量、物理性质和PGE_2、PGF_(2α)的含量。结果表示,放器组妇女月经中期一次取样的宫颈粘液平均重量为275.43±167.1毫克,对照组为226.56±150.22毫克(P>0.2)。两组妇女宫颈粘液的物理性质(透明度、粘稠性、拉丝度和结晶型)没有差别。宫颈粘液中PGE_2在放器组为41.00±22.06pg/毫克,对照组为39.12±27.32pg/毫克;PGF_(2α)在放器组为66.34±42.42pg/毫克,对照组为73.15±52.56pg/毫克(P>0.5)。两组妇女月经中期一次取样宫颈粘液在量、物理性质和前列腺素E_2、F_(2α)的含量上未见显著差异。
In order to explore the changes in the uterine environment of women who have been placed with IUDs and those who did not use them, 35 cases of women who had been released for 10 months were examined for the amount of cervical mucus during the metaphase menstrual cycle (days 10-14 of the menstrual cycle) Physical properties and PGE_2, PGF_ (2α) content. The results showed that the average weight of cervical mucus sampled once in the menstrual period was 275.43 ± 167.1 milligrams and 226.56 ± 150.22 milligrams in the control group (P> 0.2). There was no difference in the physical properties (clarity, consistency, degree of draw, and crystallinity) of cervical mucus in both groups. Cervical mucus in the PGE 2 group was 41.00 ± 22.06 pg / mg in the control group, 39.12 ± 27.32 pg / mg in the control group; PGF 2α was 66.34 ± 42.42 pg / mg in the group with the control group and 73.15 ± 52.56 pg / Mg (P> 0.5). There was no significant difference in the quantity, physical properties, and prostaglandin E_2, F_ (2α) contents of cervical mucus between the two groups in the first menstrual period.
