목적 : 자궁내막증은 진단시 다른 질환과의 감별이 어려우며 치료 후에도 재발 가능성이 높아 유용한 혈액지표의 개발이 요구되고 있다. 이에 저자 등은 자궁내막증 환자에서 치료 전 후와 재발시의 CA125 및 CA19-9 혈청값의 동태를 분석함으로써 자궁내막증의 진단 및 임상경과 추적검사와 재발에 대한 예측인자로서의 유용성을 알아 보고자 하였다. 방법 : 1994년 1월부터 1998년 12월까지 월경통이나 불임, 골반통 등을 주소로 이화여자대학교 목동병원 산부인과 외래를 내원한 환자 중, 복강경 및 개복술 시행 후 자궁내막증이 확인된 88명을 대상으로 하였다. 내원시와 치료개시후 3-6개월에 추적검사된 CA125와 CA 19-9을 후향성으로 조사, 분석(retrospective analysis)하였다. 결과 : 자궁내막증 환자군의 혈청 CA125와 CA19-9의 치료 전 평균치는 각각 81.0±252.5 및 36.6±53.4(mean±2SD,U/㎖)으로 대조군의 11.6±12.8 및 9.4±8.6 에 비하여 유의하게 높았고(p<0.05), 전체 민감도는 CA125가 53.4%, CA19-9이 42.9%, 병합시 64.3%였으며 제 3,4기의 경우 각각 85.4% 및 55.0%로 제 1,2기에 비하여 유의하게 증가하였다(p<0.05). 혈청 CA125는 병기에 비례하여 유의한 상승을 보였고(p<0.05) CA19-9는 증가하는 경향을 보였으며(p=0.055), 양자 모두 치료 후 유의하게 감소하였다(p<0.05). 또한 치료 종결 후 보다 재발시 혈청 CA125가 유의하게 증가하였다(p<0.05). 결론 : 혈청 CA125와 CA19-9는 자궁내막증 환자에서 진단시 질환의 중증도를 판정하고 치료 경과 및 재발예측을 위한 추적검사로서 유용하다. Objective : Because endometriosis is difficult to diagnose and has a high recurrence rate after treatment, a reliable serum marker of endometriosis is necessary. Therefore, the aim of this study is to measure the serum levels of CA125 and CA19-9 in patients with endometriosis before and after treatment and during recurrence, and to assess the usefulness of these levels in the diagnosis, clinical follow up and prediction of recurrence in endometriosis.Methods : Eighty-eight patients who visited the department of Obstetrics and Gynecology of Ewha Mokdong Hospital from January 1994 to December 1998 and were diagnosed as endometriosis by laparoscopy or explo-laparotomy were enrolled as subjects. A retrospective analysis of serum CA125 and CA19-9 levels at 1 month before and 3 to 6 months after initiation of treatment was done.Results : The serum CA125 and CA19-9 levels of endometriosis group(81.0±252.5, 36.6±53.4 ; mean±2SD, U/ml) before treatment was significantly higher than control group(11.6±12.8, 9.4±8.6)(p<0.05). Overall sensitivity rate for CA125, CA19-9 levels and both was 53.4%, 42.9% and 64.3% respectively. The sensitivity rate for endometriosis, stage 3 and 4(85.4%, 55.0%) was significantly higher than that, stage 1 and 2(p<0.05). The serum CA125 level in endometriosis group showed a significant increment according to stages(p<0.05) while the serum CA19-9 level showed an increasing trend(p=0.055) and both levels decreased significantly after treatment(p<0.05). The serum CA125 level was also higher at recurrence after treatment(p<0.05). Conclusion : The serum CA125 and CA19-9 levels are a useful marker for diagnosing severity of disease, monitoring efficacy of treatment and predicting recurrence in endometriosis.

목적 : 자연 유산을 예측할 수 있는 검사로써의 질식 초음파의 유용성과 질식 초음파 소견과 염색체 이상의 연관성을 알아보고자 한다. 방법 : 1996년 3월부터 1999년 6월까지 이화여자대학교 목동병원 산부인과에서 임신 초기에 자연 유산된 환자 48예의 질식 초음파 소견과 유산물의 염색체 검사 결과를 후향적으로 조사하였다. 결과 : 염색체 이상의 빈도는 47.9%였고, 발견된 염색체 이상은 삼염색체성(trisomy) 31.2%(단순 삼염색체성 27.0%, 이중 삼염색체성 4.2%), 일염색체성(monosomy) X 8.4%, 다배수성(polyploidy) 8.4%(삼배성(tripoidy) 4.2%, 사배성(tetraploidy) 4.2%)의 빈도 순이었다. 삼염색체를 보이는 경우 그 평균 연령은 30.2±4.9세이고, 과거 자연 유산 횟수는 1.0±0.9회였으며 , 16번 삼염색체가 23.0%로 그 빈도가 가장 높았다. 5번, 22번 염색체의 삼염색체와 이중 삼염색체에서는 그 평균 연령이 각각 38.0, 36.0±2.8세와 35.5±5.0세로 정상군에 비해 증가되어 있었으나 통계학적인 유의성을 증명하지는 못했다. 다배수성을 보이는 경우, 그 평균 연령은 30.5±3.7세, 과거 자연 유산 횟수는 1.0±2.0회로 정상군과 비교했을 때 통계학적으로 유의한 차이를 보이지는 않았다. 일염색체성 X의 평균 연령은 27.5±1.7세로 정상군에 비해 평균 연령이 감소하였으나 통계학적 유의성은 없었고, 과거 자연 유산 횟수도 1.0±0.8회로 차이가 없었다. 질식 초음파 소견과 염색체 이상 여부와는 상관성이 없었고, 태아 심음이 확인되었을 때의 태아 머리-둔부 길이의 측정치/기대치 비는 정상 대조군에 비해 유산군에서 유의하게 작았다. 결론 : 임신 초기의 연속적인 질식 초음파 검사는 자연 유산을 진단하는데는 유용한 검사이나 유산군에서 염색체 이상 유무를 진단하는데 유용한 지표로 사용되기는 어렵다. Objective : To investigate the importance of transvaginal ultrasonographic findings of spontaneous abortion and the relation of transvaginal ultrasonographic finding and the karyotype of abortus. Materials and Methods : Transvaginal sonography was undergone to 48 subjects with spontaneous abortion in their early pregnancies who had visited Ewha Womans University Mokdong Hospital, from March 1996 to June 1999. A chromosome analysis of their aborted products was done. Results : The frequency of chromosome abnormalities of abortus was 47.9%. Among the chromosomal abnormalities, trisomy was 31.2%(simple trisomy 27.0%, double trisomy 4.2%), monosomy X 8.4%, poliploidy 8.4%(tripoidy 4.2%, tetraploidy 4.2%). The average maternal age for trisomy was 30.2±4.9, and their past number of spontaneous abortions was 1.0±0.9, with trisomy 16 most frequent with 23.0%. In the case with trisomy 5, 22, and double trisomy, the average maternal age was increased with 38.0, 36.0±2.8, 35.5±5.0, respectively. However, no significant relevance could be found. The average maternal age for polyploidy was 30.5±3.7, and their past number of spontaneous abortions was 1.0±2.0. No significant relevance could be found compared with normal karyotypes. The average maternal age for monosomy X was 27.5±1.7, which is lower than the average maternal age for normal karyotypes, but not significantly so. The mean number of past abortions was no different with 1.0±0.8. No significant relevance could be found between ultrasonographic findings and chromosomal abnormalities. The measured/expected crown-rump length ratio of the aborted group was smaller than those of the control group. Conclusion : Serial ultrasonographic findings in early pregnancies help to diagnose spontaneous abortion, but not efficient to diagnose chromosomal abnormalities in the aborted group.

This study seleoted nine left handers and eight right handers registero with Korean University Baseball Federation to measure the distarce, time, and stride from home base to the first base, when batting. The results of this study are as follows: 1. The stance measured for the right hander was 783cm and 70.2cm for the left hander. The stride measured for the right hander was 109.9cm and 186.33 for the left hander. The diffenence between the stance and the strice shows 36.1cm for the right hander and 36.3cm for the left hander, indiceting the wider stride. 2. Compared the right hander and the left hander in time of batting, 1) When batting from the right batting place, the left hander was disadvantageous of 80cm in distance, 0.25 in time, and 1.25 in stride. 2) When batting from the hight batting plece, the right hander was disadvantageous of 86cm in distance, 0.19 in time, and 0.6 in stride. 3) When compared batting of the left hander from the left batting place and the right hander from the right batting place, the batting from the right batting place was disedvantegeous of 78cm in distance, 0.31 seconds in time, and 0.8 in stride, compared with the batting from the left batting place. 4) Considering the batting of the left hander on the right batting place, comparedwwith that of right hander on the left batting place, this study shows that the batting from the right barting place was disadventageous of 89 cm in distance, 0.21 seconds in time, and 0.9 steps instride. 3. In the aspect of stride by the left hander was 85.6cm, 103.5, for the second stride, and the final stride was 191.7. It was also measured that the first stride by the right hander was 82.9cm, 103.4 for the second stride, and the final was 173.3cm.
