송찬호,양영호,김세광,김인규,박용원,송경순,김동욱,차동현,유향숙 대한산부인과학회 1994 Obstetrics & Gynecology Science Vol.37 No.12

본 연구는 유전자내 탐침(intragenic marker)인 BclI-intron 18, XbaI-intron 22 및 유전자외 탐침 (extragenic marker) 인 St14 VNTR을 이용하여 중합효소연쇄반응(PCR)법으로 4가계에서 혈우병 A 보인자 진단과 산전 태아진단을 시도하여 다음의 결론을 얻었다. A, B가계 태아의 판정은 융모막 융모(villi)를 PCR 분석하여 남아임이 확인되었다. 1. A 가계는 XbaI을 이용하였는데 큰아들이 혈우병 A로 XbaI 처리시 68bp에서 양성띠를 나타내었고 산모와 할머니는 96bp외 68bp 모두 다 양성띠를 나타내어 68b(+)인 보인자이며, 태아(융모막 융모)는 96bp에서 양성띠를 나타내어 정상임을 알 수 있었다. 이 가계는 BclI 처리시는 informative 하지 못하였다. 2. B가계는 아들이 혈우병이 A로 사망한 가계로 St 14 VNTR을 이용하였는바, 정상인 아들은 1280bp St 14 VNTR 대립유전자에서 양성띠를 나타내었고 산모는 1280 bp/700bp 할머니는 1470 bp/700 bp 대립유전자에서 각각 양성띠를 나타내어 700bp 대립유전자가 혈우병 A 이환과 관련된 것임을 알 수 있다. 따라서 태아 (융모막 융모)는 1280bp 대립유전자에서 양성띠를 나타내 정상아임을 알 수 있다. 3. C 가계는 St 14 VNTR을 이용하여 딸의 보인자 여부를 진단한 예로, 아들은 혈우병 A환자로 1390 bp St 14 VNTR 대립유전자에 양성띠를 나타내었고 어머니는 1390 bp/ 1330 bp, 아버지는 700bp에서 양성띠를 보였다. 딸은 1330bp/ 700bp에서 양성띠를 나타내어 양부모의 정상 대립 유전자 즉, 1330bp 와 700bp를 받아 정상임을 알 수 있었다. 4. D 가계는 혈우병 A 아들은 1280 bp St 14 VNTR 대립유전자에 양성띠를 나타내었고 어머니, 할머니는 1280 bp/700 bp, 아버지는 1390bp 대립유전자 양성띠를 나타내어, 1280pb 대립유전자가 병의 이환과 관련되어 있음을 알 수 있다. 딸(피검자)은 1390bp/700bp 로 보인자가 아님을 알 수 있다. 이상의 연구결과로 intragenic marker (BclI-intron 18, XbaI-intron 22)와 extragenic marker (St 14 VNTR )를 이용한 중합효소 연쇄반응(PCR)법은 혈우병 A의 보인자 및 산전태아 진단에 상당히 유용하며, 획기적인 방법으로서 임신초기에 가능하며, 앞으로 착상전 유전진단에도 이용될 것으로 사료된다. Objectives : In this study, polymerase chain reaction (PCR) was used to determine the status of hemophilia A gene carriage in women from hemophilia A family and to evaluate the efficacy of PCR in prental genetic diagnosis of hemophilia A. Methods : Fetal sex determination from chorionic villi was carreid out by PCR using Y-chromosome specifc sequence(Y-1, Y-2), PCR was also run to identify intragenic RFLPs(BclI and XbaI) and extragenic marker (St14 VNTR) from the bloods of hemophilia A family (4 cases) to detect female carriers and establish prenatal diagnosis. Results : Fetal sex in the families A and B studied were both males, based on the presence of Y-chromosome specific band. In the family A, the BclI site was present in the fetuses and family members tested, thus, this site was noninformative. However, in this family, heterozygosity of the fetus, being tested was demonstrated using XbaI as thus normal. In the family B, using BclI and XbaI were noninformative, however, the subsequent use of an extragenic marker (St 14 VNTR) extablished normal Phenotype of fetus. In the families C and D, using St14 VNTR it was determined that the two daughters did not inherit the mutation. Conclusions : Carrier detection and fetal diagnosis of hemophilia A through PCR is useful, innovative, and accurate, whice can be done within a few hours and possible in early pregnancy.

산전유전검사를 받을 임산부 22예를 대상으로 이들의 말초혈액을 채취하여 Y chromosome-specific ZFY gene DNA sequence와 Y chromosome 단완의 DYS 14 locus에 위치한 Y-specific sequence를 nested polymerase chain reaction assay법으로 증폭하여 산전 태아 성(fetal sex)판정을 시도하여 다음과 같은 결과를 얻었다. 1. ZFY 유전자의 primer인 Z1, Z2 및 Z3, Z4를 이용한 중합효소연쇄반응 결과, 여아 및 남아를 임신한 전예에서 양성띠가 나타나 비특이성을 보였다. 2. Y-chromosome DYS 14 locus의 sequence primer인 Y1.5, Y1.6 및 Y1.7, Y1.8 primer를 이용한 중합효소연쇄반응 결과, sensitivity는 76.9%, specificity는 55.5%였으며, positive 및 negative predictive value는 각각 71.4%와 62.5%였다. 이를 임신주수별로 분석하여 보면 임신 초기, 중기 및 말기의 positive predictive value는 각각 66.6%, 66.6%와 80%로, negative predictive value는 각각 50%, 50% 및 100%로 나타났으며, 임신 9-16주에는 여아를 임신한 임산부 중 남성 특이의 band가 나타나는 경우가 6예중 3예, 남아를 임신한 임산부 중 남성특이의 band가 나타나지 않는 경우가 7예중 3예로 낮은 신회도를 보였으나 임신 18-40주에는 남아인 경우 1예를 제외하고는 남성 특이 band가 나타났으며, 여아인 경우는 모든 예에서 198 base pair의 남성 특이 band가 나타나지 않았다. 저자들은 본 연구에서 모체 말초혈액에서 중합효소연쇄반응(PCR)을 이용한 태아의 성판정은 임신후기에는 가능하나 임신초기에 있어서는 그 신뢰도가 낮은 것으로 생각 된다. 따라서, 임신 초기 모체혈액내에 있는 태아세포만을 선별적으로 구별할 수 있는 방법을 이용하여 Y1.5, Y1.6 및 Y1.7, Y1.8 primer를 이용 PCR을 하면 정확한 태아의 성판정이 가능할 것으로 사료된다. 본 연구는 연세대학교 의과대학 교수연구비에 의해서 이루어짐 (1994년도). Objectives : Detection of Y-chromosome specific gene in the maternal circulation has clinical importance because of its potential usefulness in determining fetal sex in mothers with severe X-linked disorders such as classic hemophilia A and Duchenne`s muscular dystrophy. Numerous attempts have been made to identify Y specific gene in bloods of mothers bearing male fetuses, however, the results have been controversial. Therefore, we have investigated the use of a nested polymerase chain reaction assay for the detection of a fetal specific Y-chromosome sequence. Methods : Y chromosome specific ZFY gene DNA sequence(using Z1, Z2 and Z3, Z4 primers) and Y chromosome sequence in DYS 14 locus (using Y1.5, Y1.6 and Y1.7, Y1.8 primers) have been identified by an in vitro enzymatic deoxyribonucleic acid amplification method in peripheral blood specimens of 22 pregnant women with gestational ages of 9 to 40 weeks. Results : All women bearing male or female baby were positive for the ZFY gene. Thirteen fetuses were confirmed as males by amniocentesis or chorionic villi sampling, and 10 of these were positive for the Y chromosome specific sequence in DYS 14 locus using Y1.5, Y1.6 and Y1.7, Y1.8 primers(sensitivity 76.9%), however, 4 of the 9 cases diagnosed as females were also positive(specificity 55.5%). Positive and negative predictive values were 71.4% and 62.5%. In terms of the gestational age, positive predictive values of 66.6%, 66.6% and 80% were obtained for the first, second and third trimesters, respectively. The corresponding negative predictive values are 50%, 50%, and 100%, respectively. Conclusion : Fetal sex determination by PCR employing maternal peripheral blood is usually possible in late pregnancy. It is less reliable in early pregnancy. It appears that using a method separating fetal cells from maternal blood and then by running PCR on these cells with Y1.5, Y1.6 and Y1.7, Y1.8 primers could make a fairly accurate fetal sex determination.

Abdominal pregnancy is a rare condition and potentially life-threatening variation of ectopic gestation within the peritoneal cavity, and it represents a grave risk to the maternal health. Primary abdominal pregnancy is very rare and in most instances abdominal pregnancy is secondary, result from tubal abortion or rupture of a previous uterine incision. The conceptus then reimplants onto the peritoneal surfaces, omentum, and bowel. Frequency has been estimated to be 10.9 abdominal pregnancies per 100,000 live births and 9.2 per 1,000 ectopic pregnancies. The purpose of this paper is to report our experience with a primary abdominal pregnancy associated with intrauterine contraceptive device, with a brief literature review.

Evolution of the Near-Field Patterns into the Far-Field in Surface Plasmonic Band Gap Nano-Structures

홍성철,박규환,Ch. Lienau,김대식,J. Kim,J. W. Park,K. H. Yoo,. H. Han,V. Malyarchuk,Y. C. Yoon 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.46 No.2

We study emission patterns in periodic nano-hole arrays perforated in a metal film. In the nearfield region, higher order multiple components of diffraction interfere with each other to generate complicated spatial patterns. These patterns simplify to a sinusoidal one in the intermediate region and become either homogeneous or sinusoidal in the far-field region, depending on whether the excitation wavelength is larger or smaller than the lattice constant. For an incident wavelength much smaller than the lattice constant, complicated patterns can survive into the far-field. Detailed analytic and numerical studies are presented, which show good qualitative agreement with experiment.
