Objective: The aim of this study was to measure the concentrations of cytokines contained in the hydrosalpingeal fluid and to evaluate the effect on the mouse embryo development with the different cytokine concentration. Methods: The hydrosalpingeal fluids (HSF) were collected during the surgery for hydrosalpinx which was confirmed by hysterosalphingogram. The cytokines in HSF including interleukin (IL)-$1{\alpha}$, IL-$1{\beta}$, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-$\alpha$, Interferon-$\gamma$ (IFN-$\gamma$), vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), monocyte chemotactic protein-1 (MCP-1) were measured by ELISA method. HSF were added up to culture media with 5%, 10%, and 30% concentrations. The blastulation rates were compared. Results: IL-$\alpha$, IL-$1{\beta}$, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-$\alpha$, IFN-$\bamma$, VEGF, EGF, and MCP-1 were detected, but the concentrations were different from each sample. IL-6 and IL-10 were increased in HSF-1 group, and IFN-$\gamma$, MCP-1, VEGF were increased in HSF-2 compared with normal serum range. The Th1/Th2 ratio of HSF-2 (IFN-$\gamma$:IL10) was highly elevated to 61.64, compared with that of HSF-1 (3.69). The blastulation rate was significantly decreased in HSF-2 group (27.7%) compared those of the HSF-1 group (74%) and control group (76.7%). It showed the trend that the blastulation rate was decreased depending on the concentration HSF of culture media in HSF-2 group, but it was not statistically significant. Conclusion: The composition and concentration of cytokines in each HSF were different, and increased proinflammatory cytokines in HSF might be associated with poor embryonic development. Further study will be needed about the effect of each cytokines in HSF.

연구목적:인간의 체외수정 및 배아이식술에서 난관수종을 갖는 환자에서 임신율과 착상률이 감소된다는 보고들이 있지만 이에 대한 명확한 기작은 밝혀지지 않았다. 본 연구에서는 생쥐 배아를 이용한 체외 착상모델에서 인간의 난관수종액(HSF)이 착상과정에 미치는 영향을 알아보고자 하였다. 연구재료 및 방법 난관수종액은 난관수종으로 수술을 받은 8명의 환자로부터 채취하였으며, 실험에 사용하기 전까지 냉동고에 보관하였다. 생쥐의 포배기 배아는 2-세포기배아를 3일 동안 배양하여 그 중 상태가 양호한 포배기 배아만을 선별하여 투명대를 제거한 후 사용하였다. 기본 배양액으로는 Ham's F-10을 사용하였으며, 배양 시 기본 배양액만을 사용한 경우를 group Ⅰ으로 하였고, 기본 배양액에 0.5% FBS를 첨가한 경우를 group Ⅱ, 0.5% FBS와 50% HSF를 첨가한 경우를 group Ⅲ , 100% HSF에 0.5% FBS를 첨가한 경우를 group Ⅳ,100% HSF만을 사용한 경우를 group Ⅴ로 하였다. 투명대를 제거한 포배기 배아를 각각의 HSF에 대한 5종류의 배양액에서 48시간 동안 배양하였다. 체외 착상 유무는 부착 부위에서 크기가 커진 영양세포들을 관찰하여 판정하였으며, 착상 부위의 표면적은 화상분석기를 이용하여 산출하였다. 결 과: 생쥐 배아의 체외 착상률은 group Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ에서 각각 0%, 98.9%, 77.5%, 40.4%, 10.0%로 나타났으며, 착상 부위의 평균 표면적은 group Ⅱ, Ⅲ, Ⅳ, Ⅴ에서 각각 $74,675{\pm}25,201{\mu}m^2$, $59,024{\pm}25,877{\mu}m^2$, $45,156{\pm}22,654{\mu}m^2$, $38,254{\pm}17,115{\mu}m^2$이었다. 체외 착상률과 부위의 표면적은 HSF의 농도가 증가함에 따라 통계적으로 유의하게 감소하였다(p<0.001). 결론:인간의 난관수종액(HSF)은 생쥐 배아의 체외 착상과 영양배엽세포의 증식을 억제하는 것으로 확인되었으며, 이러한 원인이 난관수종을 갖는 환자에서 임신율이 낮은 것과 밀접한 관련이 있을 것으로 생각된다.

This study was performed to identify the effect of the hydrosalpinx fluid on sperm motility. It has been reported that the patients with hydrosalpinx show the outstandingly lower success rate than other patients having infertility by different factors. It is unclear that the cause of it is influenced by hydrosalpinx fluid directly or by secondary chronic inflammation of endometrium. We wanted to know if the hydrosalpinx fluid influences sperm motility parameters directly such that it is related to the development of infertility. Therefore, using computer assisted semen analyzer (CASA), we observed, from February to July, 1997, how sperm motility, sperm progressive motility, sperm curvilinear velocity, sperm lateral head displacement, sperm straightness and sperm linearity change after treating normal sperm with hydrosalpinx fluid to evaluate sperm function on infertility. The result was that the study group (n=32) has the tendency to differ from the control group (n=32) on sperm motility, progressive motility, curvilinear velocity, lateral head displacement, straightness and linearity. We concluded that the hydrosalpinx fluid, with varying degree, directly has the harmful effects on sperm motility parameters, that is, curvilinear velocity, lateral head displacement and linearity of sperm which are related to the hyperactivation, hence decreased capacitation.

In our previous study, we observed that hydrosalpingeal fluid (HSF) adversely effect mouswe embryo development and hatching. The aim of this study was to evaluate the effect of HSF as assessed by the blastocyst development rate (BDR) and by cell counting in vitro. HSF was collected from ninie patients undergoing salpingoneostomy to correct hydrosalpinx. Two-cell embryos were obtained from superovulated ICR mice. T6 medium and $T6{\pm}0.4%$ bovine serum albumin were used as control media. T6 medium containing 10% or 50% HSF and 100% HSF from each patient were used as test media. Nine to 15 embryos were cultured in micro drops prepared from each of these media. To assess the total cell number within each blastocyst, the blastocysts were fixed and stained with Hoechst 33342 to facilitate cell counting. The mean BDR in two control media were 88.89% and 85.40%. The mean BDR in media containing 10%, 50%, 100% HSF were 85.87%, 89.58% and $75.57%^*$, respectively ($^*$: p<0.05). The overall mean cell count $({\pm}SEM)$ in control media were $87.6{\pm}9.65\;and\;90.12{\pm}11.38$. The BDR was affected adversely only by 100% HSF and not in media containing 10% or 50% HSF. Mean cell counts were decreased significantly only in blastocysts cultured 100% HSF ($63.8{\pm}13.66$; p<0.01) but not in blastocysts cultured in 10% or 50% HSF ($91.3{\pm}12.44\;and\;82.9{\pm}18.27$, respectively). Thus, it is concluded that HSF has no embyotoxic effect but has a mildly negatively effect on embryonic growth and development.
