The aim of this study was to investigate whether a relationship exists between the presence of low numbers of leukocytes in normal ovulatory cervical mucus and sperm quality and lipid content after migration. The percentages of live, motile and morphologically normal spermatozoa, movement parameters assessed by computer-aided sperm analysis （CASA）, and ionophore-induced acrosome reaction measured by flow cytometry were determined before and after migration. High-performance liquid chromatography with ultraviolet detection was used to measure the sperm lipid content, including the various diacyl subspecies. The number of leukocytes found in solubilized mucus samples was counted using a haemocytometric method. Overall, the presence of leukocytes in the cervical mucus samples did not significantly influence sperm motility and morphology, sperm kinematic parameters, or the sperm content in sphingomyelin or cholesterol. In contrast, after migration, the decrease in various sperm diacyls and the level of induced acrosome reaction was significantly less pronounced in mucus samples containing ≥10^4 leukocytes than in mucus samples with no or rare leukocytes whereas the level of induced acrosome reaction was higher. The present data suggest that the low level of leukocytes found in normal ovulatory cervical mucus could influence the process of sperm lipid remodelling/capacitation.

CYCLIC CHANGES OF LACTATE DEHYDROGENASE IN cervical mucus

引用

Journal of Pharmaceutical Analysis 1994年第2期8卷 134-137,158页

作者：王红曹缵孙翁其亮毛文军杨建业

Lactote dehydrogenase (LDH) in cervicai mucus of thirteen ovulatory women was serially determined and serum LH, FSH, E2, P and cervical mucus score were measured. There was a cyclic change in LDH activity, being high in follicular phase and luteal phase, but increasing significantly in periovulatory phase. In follicular phase, there was a negative correlation between LDH activity and E2 (r=-0. 76, Pcervical mucus measurment can be used as an index of predicting ovulation.

Level of Copper Ion in cervical mucus of Various Duration after Inserting VCu200IUD

引用

Journal of Reproduction and Contraception 1996年第1期7卷 25-31页

作者：刘庆喜黄祝潘琢如

The purpose of the study was to test the effective period of VCu200 *** concentration of copper ion was measured with non-flame atomic absorption spectrophotometer *** average concentration of coPPer ion(x±s.)was 2.66±0.58μg/g cervical mucus wet weight(μg/g·M·W·W) in the first year,then gradually decreasing to 0.91±0.16μg/g·M·W·W in the fifteenth-year group of VCu200 *** was an average of 0.35±0.08～0.56±0.14 μg/g·M·W·W in the control *** showed that the concentration of copper ion was decreasing with prolongation of use of VCu200 IUD and there was statistically significant difference between VCu200 IUD group,on the one hand,and the stainless steel ring group and the control group(P0.05).It was reported in the literature that the concentration Of copper ion in 1.0μg/ml had the action of antifertility,and it was found that the concentration of copper ion was higher than 1.0μg/ml in the tenth year after insertion of VCu200 *** suggested that effective period of VCu200 IUD was at least ten years.

作者：姚军周苏文北京第二医学院附属宣武医院

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PGE2、PGF2α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... 详细信息

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PGE2、PGF2α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PGE2在放器组为41.00±22.06pg/毫克,对照组为39.12±27.32pg/毫克;PGF2α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E2、F2α的含量上未见显著差异。

Risk Factors for Preterm Delivery in Asymptomatic Singleton Pregnant Women with a Sonographic Short Cervix

引用

Open Journal of Obstetrics and Gynecology 2021年第12期11卷 1711-1724页

作者： Satoshi Yoneda Noriko Yoneda Shigeru Saito Department of Obstetrics and Gynecology University of Toyama Toyama Japan

Objectives: Although an asymptomatic short cervix is a risk factor for spontaneous preterm birth (SPTB), the risk factors for SPTB among those with short cervix remain unknown. We herein investigated risk factors for preterm delivery (PTD) at Methods: This was a retrospective study. Seventy-three asymptomatic pregnant women with a sonographic short cervix (excluding visible bulging fetal membranes) were selected, and the relationship between clinical or biochemical risk factors and preterm delivery (PTD) at Results: Thirteen cases (17.8%) had PTD at ≥34 weeks (p dentified CM-IL-8 ≥ 803.5 ng/mL [21.3 (3.0 - 260), p = 0.002] and cervical length ≤15 mm [17.1 (1.9 - 517), p = 0.008] as independent risk factors for PTD at Conclusions: Evaluation for cervical inflammation may be necessary for appropriate treatment strategies in asymptomatic pregnant women with a short cervix. Cervical inflammation warrants further study.
