목 적 : 태아시기의 장기간 스트레스는 부신의 호르몬 합성에 영향을 미치는 것으로 알려져 있다. 분만 동안의 급성 스트레스와 제대혈 코티솔간의 상관관계를 보고자 본 연구를 시행하였다. 방 법 : 총 58명의 신생아를 대상으로 분만 즉시 제대혈을 10 mL 채취하였고, $4^{\circ}C$에서 2,000 rpm으로 20분간 원심 분리하여 혈청을 분리한 후, 즉시 $-70^{\circ}C$에 냉동 보관하였다. 코티솔의 측정은 Coat-A-Count Cortisol Kit를 사용하여 RIA방법으로 측정하였다. 분만 스트레스와의 관계를 알아보기 위하여 재태 연령(34주 이하, 35-37주, 38주 이상), 분만방식(제왕절개 분만 vs 질식분만), Apgar 점수, 자궁수축 유무 등에 따른 코티솔 농도를 비교하였다. 결 과 : 제대혈 코티솔 농도는 재태 연령에 따라 증가하는 양상을 보였고(P<0.001), 제왕절개 분만 군보다 질식 분만 군에서 코티솔 농도가 통계적으로 유의하게 높았다(P<0.001). 자궁수축을 동반하는 경우가 동반하지 않았던 경우보다 코티솔 농도가 높았으며(P<0.05), 분만 진통시간이 길수록 코티솔 농도가 유의하게 높았다(P<0.05). 코티솔 농도는 1분 Apgar 점수가 낮았을 때 유의하게 낮은 농도를 보였다(P<0.05). 결 론 : 제대혈 코티솔은 분만스트레스와 밀접한 관련성이 있으며, 신생아의 출생 후 예후와도 관련이 있을 것으로 생각된다. Purpose : Long-term stress to the fetus causes alterations in adrenal steroidogenesis. The purpose of this study was to analyze the association of cord blood cortisol with stress during delivery. Methods : Cord blood samples were collected from 58 neonates at once to labor. Cortisol was measured by RIA method(DPC, USA). Cortisol level according to gestational age(<34, 34-37, >38 wks) and method of delivery(Cesarean section vs. vaginal delivery), Apgar score and uterine contraction, were compared to know stress during labor. Results : Cortisol of cord blood had considerable differences between each group, according to gestational age(P<0.001). It was statistically higher in the cases of vaginal delivery than cessarian delivery(P<0.001). The concentration of cortisol was significantly higher according to duration of labor (P<0.05). There was a significant relationship between cortisol level and uterine contraction(P<0.05). The concentration of cortisol was significantly low when Apgar score at 1 min was low(P<0.05). Conclusion : Cord cortisol has close association with stress during labor. And so do with post birth prognosis of neonate.

Vegetable soup has been reported to have anti-inflammatory, anti-oxidative and anti-cancer effects. In this study, five kinds of vegetable soup were developed using a new manufacturing process and compositional changes in raw material, and anti-cancer and immuno-stimulatory activities were evaluated. Cytotoxicity tests based on MTT assay revealed that all vegetable soups had strong inhibitory effects against CT26 mouse colon cancer cells, with soups including Solomon's seal being most effective based on comparison of $IC_{50}$ values. Apoptosis in response to vegetable soup was occurred by 3-5 fold on cancer cells compared to normal cells. Mouse splenocytes increased by 266-541% in response to addition of vegetable soup in an in vitro proliferation experiment. In co-culture with splenocytes and CT26 cancer cells, splenocytes increased by more than 280% in every vegetable soup treatment, while cancer cells decreased by about 60% and cytokines such as $IFN- {\gamma}$ and IL-12 were secreted from splenocytes in high levels only in response to vegetable soup including Solomon's seal. In conclusion, all vegetable soups developed in this study had anti-cancer effects, and vegetable soup including Solomon's seal showed the strongest anti-cancer and immuno-stimulatory effects. These results suggest that functionality of vegetable soup could be increased by changes in manufacturing processes and raw materials composition.

임현정(Hyun Jung Lim),정혁(Hyuk Jung),조남수(Nam Su Jo) 대한산부인과학회 2002 Obstetrics & Gynecology Science Vol.45 No.6

목적 : 기능성 자궁 출혈은 부인과 영역에서 가장 흔한 질환이다. 자궁 부정출혈의 기질적인 이상에는 만성 경부염, 점막하 근종, 자궁내막 용종, 자궁내막암 등이 있다. 이번 연구에서는 자궁 부정출혈환자에서 자궁 내시경을 이용한 자궁내막생검을 시행하여 출혈의 정확한 원인을 찾고자 하였다. 연구 방법 : 2000년 2월부터 2000년 8월까지 부정자궁출혈을 주소로 조선대학교부속병원 산부인과에 내원하여 자궁내시경을 이용해 자궁내막생검을 받은 106명을 대상으로 하였다. 연구 대상들은 소변 임신 반응 검사와 자궁경부 세포진에서 모두 음성을 보였고 골반내진과 초음파상 부정자궁출혈을 일으킬 만한 기질적인 원인이 없었다. 자궁내시경을 통한 생검을 실시한 후 연구대상의 나이, 분만력, 생검결과들을 후향적으로 분석하였다. 결과 : 연구대상의 평균 연령은 43세였으며 평균 분만력은 2.6명이었다. 생검결과에서 가장 흔한 결과는 증식기로 28.3%를 차지하였다. 다음으로는 분비기가 17.9%였고 단순 내막 과대증식이 13.2%, 자궁내막 용종이 10.6%, 만성 경부염이 4.7%를 차지하였다. 점막하 자궁 근종, 자궁내막암, 복합성 자궁내막 과대증식은 각각 3.8%를 차지하였다. 시술전 기능성 자궁출혈로 생각되었던 106명의 환자중 단지 63명 (59.4%)만이 자궁내시경을 이용한 생검을 통해 진정한 기능성 자궁출혈로 진단이 되었고 나머지인 43명 (40.6%)은 자궁내에 기질적인 병변을 가지고 있음이 밝혀졌다. 결론 : 자궁 부정출혈을 주소로 환자들이 내원했을때 의사들은 기질적인 원인을 의심해 보고 정확한 진단을 내린 후 환자들을 치료해야 한다. 이러한 환자들에게 자궁내시경을 이용한 자궁내막 생검은 정확한 진단과 치료계획을 수립하는데 매우 유용한 방법이라 할 수 있다. Objective : Abnormal uterine bleeding is one of the most common disorder in gynecologic department. Organic causes of abnormal uterine bleeding are chronic cervicitis, submucosal myoma, endometrial polyp, endometrial malignancy. To find the exact cause of uterine bleeding and rule out the organic uterine disorder in the patients who considered dysfunctional uterine bleeding, hysteroscopic examination and endometrial biopsy were used. Methods : Study group were 106 patients, who received hysteroscopic endometrial biopsy from 2. 2000 to 8. 2001.with abnormal uterine bleeding, negative in urine pregnancy test, normal in cervix cytology, and without organic lesion causing uterine bleeding in pelvic exam and ultrasonography. Age, parity, hysteroscopic biopsy result were analyzed retrospectively. Results : Mean age of the study group was 43 and mean parity was 2.6. When final hysteroscopic biopsy histology were analysed, proliferative phase was most common (28.3%). Next were secretory phase (17.9%), simple hyperplasia (13.2%), endometrial polyp (10.6%), chronic endocervicitis (4.7%). Submucosal myoma, endometrial cancer, complex hyperplasia were detected in 3.8% each one. Of 106 patients, who considered dysfunctional uterine bleeding, only 63 (59.4%) patients were proved true DUB on hysteroscopic biopsy. Remainder had organic disorder (40.6%). Conclusion : When patients visited the hospital with abnormal uterine bleeding, doctors should be suspicious of endometrial organic disease and treat the patients with exact diagnosis. In these patients, hysteroscopic examination and biopsy were very useful and safe method to determine exact diagnosis and treatment plan.

Interesting education which utilizes cyber visual and audio multimedia effects, we regard it as a very effective education but those programs are not prepared yet. So, the purpose of this research is to provide a new direction for cyber fashion education with the use of avatars as the multimedia factor to increase student`s interest and understanding. First, we investigated the present situation of fashion cyber education and the present avatar usage situation online, and also we searched literature and the internet to investigate the general theory of design. Second, we used Adobe photoshop 7.0 to make avatars, then, we used Macromedia Flash MX to design the avatar on our web site, and to make it look more realistic. According to the research results, cyber fashion education is usually used as marketing in certain areas, and for middle school, and high school students it is mainly used as text and lecture videos. When searching for fashion sites that use avatars, we found that most fashion shopping malls use them. Because avatars can give visual effects and also increase interest and fun, they can increase concentration and understanding and can be effective in fashion cyber education.

Congenital hemangioma (CH), which is already fully formed at birth, is a rare clinical entity that is distinctly different from the common postnatally-occurring hemangioma of infancy (HOI). These two forms of CH have been described according to their clinical courses: apart from the clinical features of presentation at birth, there is the rapidly involuting congenital hemangioma (RICH) with rapid involution shortly after birth and the noninvoluting congenital hemangioma (NICH) with neither postnatal enlargement nor spontaneous involution. It is important to recognize this uncommon disease entity NICH in the early period because it has no tendency for spontaneous regression, so timely therapeutic intervention is needed, which is in contrast to that of HOI. We present 3 patients who were 1-, 3- and 13-year-old girls with red-stippled blue to blue gray vascular lesion. They all showed their lesions since birth and the lesions remained unchanged with no subjective symptoms. Doppler ultrasonography demonstrated a well-defined fast-flowed vascular lesion confined to the dermis and subcutis. The histology commonly showed lobular growth of capillaries, centrilobular irregular and often stellate vessels, extralobular large vessels and more conclusively, negative staining for GLUT-1, which is unlike HOI.
