본 연구결과 자궁경부암 환자군에서 factor VIII을 이용한 미세혈관의 발현정도는 대조군과 비교해 200배율하 현미경하에서만 각 군간에 통계학적 차이가 있음을 확인할 수 있었으며, 여러 임상적 예후인자 혹은 생화학적 예후인자와의 상호 관련성 미비 등의 문제때문에 자궁경부암과 맥관형성과의 연관성을 아직 확인할 수 없어 추후에 계속적인 연구가 필요하리라 판단된다. Angiogenesis, the formation of new vessels, has been associated with tumor growth. Experimental evidence suggests that the neovascularization increases the opportunity for tumor cells to enter the circulation and is correlated with metastasis. To investigate if angiogenesis is a related factor in carcinoma of the uterine cervix, we counted microvessles and graded the density of microvessels in 30 paients with squamous cell carcinoma of the cervix. Tumor sections were stained immunohistochemically with factor VIII to identify all vessels. The microvessels were counted and graded in the most intense areas of neovascularization by light microscopy. Microvessel counts in patients with wquamous cell carcinoma were significantly different from those of normal cervix and chronic cervicitis in 200x field microscopy: 22.43 vs. 6.57 and 10.93 (p=0.0182). There was no correlation between microvessel count and clinical parameters such as tumor size or clinical FIGO stage. This study suggests that tumor angiogenesis could be involved in squmous cell carcinoma of the uterine cervix. However, microvessel counts may not be a prognostic value in patients having risk factors for poor clinical outcomes.

Pregnancy maintenance is dependent on the presence of a functional corpus luteum (CL) for a few weeks after implantation. However, the factors responsible for the rescue of the CL during early pregnancy have not been fully clarified. This study was designed to evaluate whether the change in size of the CL of early pregnancy, serum concentration of progesterone, 17α-hydroxyprogesterone, or β-hCG correlated with the gestational age or were predictive of pregnancy outcome. We retrospectively analysed thirty-six women between 4~9 weeks` gestation. All women underwent transvaginal ultrasound measurement of the CL size and gestational sac(or crown-rump length). Blood was drawn from each patient on the day of the ultrasound examination to measure hormone concentration. Fifteen women experienced vaginal bleed ing and abdominal pain. Among them, four women were aborted. There was no significant positive correlation between CL size and serum progesterone, 17α-hydroxyprogesterone or β-hCG both in normal and abnormal pregnancy. A positive correlation was observed between the gestational age and progesterone or β-hCG in normal pregnancy, but not in abnormal pregnancy(threatened or spontanous abortion). In conclusion, close correlation between the gestational age and serum concentration of progesterone or β-hCG may reflect the normal function of CL. Therefore, abnormal response of CL or abnormal production of β-hCG cause a disturbance in progesterone secretion leading to the abnormal pregnancy.

The cause of endometriosis has remained controversial. Recent investigation have focused on a possible role of the immune system in etiology and pathophysiology of endometriosis. Autoantibodies against endometrium have been demonstrated in the serum of women with endometriosis using immunodiffusion, passive hemagglutination and immunofluorescence. We investigated the presence of antiendometrial antibody in the sera of 63 women with endometriosis. The control group included the sera from 31 pregnant women and 29 fetal umbilical cords. Antiendometrial antibodies were assayed by passive hemagglutination. Antiendometrial antibody levels (mean±SEM) were significantly higher in the study group (51.0±10.1) than in the control group (3.9±0.6). Thirty-seven out of 63 patients (58.7%) tested positive, while all of the control group negative. In the study group, however, there was no difference in autoantibody levels by AFS stage : 33.7±10.7 in stage I, 30.3±6.0 in stage Ⅱ, 75.5±38.5 in stage Ⅲ, and 59.0±15.2 in stage Ⅳ. A positive rate of passive hemagglutination assay revealed no difference by severity of the disease : 46.2% in stage Ⅰ, 61.5% in stage Ⅱ, 66.7% in stage Ⅲ, and 60.0% in stage Ⅳ. There results suggest that serum antiendometrial antibody assay is specific and valuable for the diagnosis of endometriosis. The cause of endometriosis has remained controversial.

저자들은 임신 33^(+5주)에 심한 복수와 음낭수종이 있는 태아의 복수액을 채취하여 기존의 양 수 세포 배양법을 변형한 방법으로 염색체검사를 시행하여 성공하였으며 제대혈을 이용한 염색체검사와 동일한 핵형을 얻을 수 있었다. 따라서 복수가 있는 태아에서 적절한 산과적 치료를 위해 신속한 염색체검사 결과가 필요하나 제대혈 채취가 어려운 경우 복수천자에 의한 태아 체액을 이용하면 정확한 염색체검사 결과를 얻을 수 있으므로 기술적으로 어려운 제대혈 채취를 대치할 수 있을것으로 사료된다. 또한 임파구 배양법을 이용하면 더욱 빨리 결과를 얻을 수 있어서 산과적 치료방침의 결정에 매우 유용할 것으로 사료된다. Ultrasound-guided fetal paracentesis and cordocentesis were performed in a fetus who had massive ascites and hydrocele in third trimeste. Cells from fetal ascites were processed like amnionic fluid for karyotyping and successful result was obtained within 10 days. our present study suggests that fetal ascitic fluid may provide rapid fetal karyotyping and guideline to obsteric management in selected patients.
