dc.description.abstractObjective: The purpose of this study was to determine whether cyclooxygenase [COX]-1 and COX-2 are expressed in the pregnant human uterine cervix and if they are expressed differentially between preterm and term pregnancies.
Methods: Fourteen patients delivered between 29 and 41 weeks of gestation were matched for obstetrical history and maternal age were divided into a preterm group who delivered between 29 and 36 weeks [n=7], and a term group who delivered between 37 and 41 weeks of gestation [n=7]. Immediately after vaginal delivery cervical biopsy samples were obtained and immunohistochemicaly stained for COX-1 and COX-2 and the degree of staining was evaluated by H-scoring system.
Results: Expression of COX-1 and COX-2 was found in all epithelial and stromal cells of uterine cervical tissues of pregnancy. The expression of COX-1 and COX-2 was significantly stronger in the term group compared to the preterm group in epithelial cells [HSCORE : 2.14±0.69 vs. 1.14±0.38 ; 3.71±0.76 vs. 1.86±0.90, p<0.05], but there was no significant differences in stromal cells [HSCORE : 3.43±0.53 vs. 2.86±0.38 ; 2.43±0.53 vs. 2.57±0.98, p>0.05].
Conclusion: In the pregnant human uterine cervix, COX-1 and COX-2 are found to be expressed, and both are strongly expressed in the cervical epithelial cells of term pregnancies compared to preterm pregnancies. It is suggested that the uterine cervix, under the control of prostaglandins, is actively involved in the process of labor, and that the role of COX-2 in epithelium is particularly significant in term pregnancies compared to preterm pregnancies.

dc.description.abstract목적: 조산 산모와 정상 분만 산모의 자궁경부조직에서 cyclooxygenase [COX]-1, -2의 발현을 관찰하여 이들이 분만 과정에 관여하는 가를 밝히고, 양 군에서의 발현 양상의 차이를 보고자 한다.
연구방법: 임신 29주에서 36주 사이에 분만한 산모를 조산군 [n=7] 으로, 37주부터 41주 사이에 정상 분만한 산모를 정상 분만군 [n=7] 으로 분류하고, 각각 질식 분만 직후 자궁경부조직을 얻어 COX-1, -2의 면역조직화학염색을 시행하여 염색의 정도에 따라 H-scoring system을 적용하여 양 군에서의 발현의 차이를 살폈다.
결과: 양 군의 자궁경부조직 모두에서 COX-1과 COX-2가 발현되는 것을 알 수 있었다. 또한 COX-1은 조산군보다 정상 분만군의 상피세포 [HSCORE : 1.14±0.38 vs. 2.14±0.69, p$lt;0.05]와 기질세포 [HSCORE : 2.86±0.38 vs. 3.43±0.53, p$gt;0.05] 모두에서 강하게 발현되었다. COX-2도 상피세포에서는 조산군보다 정상 분만군에서 강하게 염색된 것을 알 수 있었고 [HSCORE : 1.86±0.90 vs. 3.71±0.76, p$lt;0.05], 기질세포에서는 조산군과 정상 분만군의 발현 정도의 차이가 없었다 [HSCORE : 2.57±0.98 vs. 2.43±0.53, p$gt;0.05].
결론: 인간의 분만후 자궁경부조직에서 COX-1과 COX-2가 발현되는 것을 최초로 밝혀 자궁경부도 prostaglandin의 조절하에 분만 과정에 능동적으로 관여하고 있음을 알 수 있었고, 특히 조산군보다 정상 분만군에서는 상피세포에서의 COX-2의 역할이 더욱 중요하다고 생각된다.
