Pregnancy-induced hypertension (PIH) is a multi-system disorder unique to human pregnancy. Although theetiology of PIH is still unknown, there is a large evidence suggesting that abnormal trophoblast invasion is occurring inearly pregnancy and that this may contribute to relative placental hypoxia and oxidative stress that may furtherexacerbate placental pathology. This study was undertaken to determine placental Cu/Zn superoxide dismutase (SOD)and Mn SOD activities and evaluate the use of M30 CytoDeath antibody to assess trophoblasts apoptotic activity innormal and PIH pregnancies. We also compared apoptotic rates as detected by M30 and TdT-mediated dUTP nickendlabelling (TUNEL). Placental expression of Cu/Zn SOD and Mn SOD were reduced in PIH as compared to normalpregnancies. M30 immunoreactivity occurred predominantly in the syncytiotrophoblasts, and a significantly highernumber of M30 positive cells in the preeclamptic placentas were found when compared with normal placentas. Thenumber of M30 positive cells correlated with another apoptotic index previously detected by TUNEL method. ─임신성고혈압에서 Caspase-related M30 CytoDeath 발현을이용한 영양막세포고사 연구김호진1, 박혜숙2, 김영주3, 4, 박보현2, 이화영1, 4*이화여자대학교 의과대학 1해부학교실, 2예방의학교실, 3산부인과학교실4이화여자대학교 의과학연구소임신성고혈압은 모체와 주산기의 사망률 및 이환률을 높이는 주요 원인이며 이의 발병에 관한 명확한 병리기전은 밝혀져있지 않으나, 태반형성 시 비정상적인 영양막 침윤으로 인한 나선동맥의 불충분한 생리학적 변화와 이로 인한 태반허혈 및산화손상이 모체의 혈관내피세포 기능변화를 유발하고, 태반의 구조적 변화를 악화시키는 것으로 알려져 있다. 본 연구는 임신성고혈압의 태반내 항산화상태와 영양막의 세포고사를 조사하고자, 정상 임산부와 임신성고혈압 환자의 출산 시 분리된태반을 대상으로 태반 내 Cu/Zn superoxide dismutase (SOD) 및 Mn SOD의 함량을 측정하였다. 또한 영양막 세포고사 연구를위하여 근래에 개발된 M30 CytoDeath 발현과 기존의 TdT-mediated dUTP nickend labelling (TUNEL)을 병행하여 관찰하고이를 통계적으로 분석, 비교하였다. 태반에 함유된 Cu/ Zn SOD와 Mn SOD 활성은 정상임신에 비하여 임신성고혈압에서 의미있게 감소되었으며, 세포고사를 표지하는 M30발현을 통하여 임신성고혈압의 융합영양막에서 그 반응성과 발현세포의 숫적증가가 관찰되었다.찾아보기 낱말 : 임신성고혈압, 영양막, 산화손상, 세포고사, SOD, M30Ho Jin Kim, Hyesook Park, Young Ju Kim, Bohyun Park, Hwayoung Lee 59

Background: Heart transplantation has become a widely accepted surgical option for end-stage heart failure in Korea since its first success in 1992. We reviewed early postoperative complications and mortality in 239 patients who underwent heart transplantation using bicaval technique in Asan Medical Center. Methods: Between January 1999 and December 2011, a total of 247 patients aged over 17 received heart transplantation using bicaval technique in Asan Medical Center. After excluding four patients with concomitant kidney transplantation and four with heart-lung transplantation, 239 patients were enrolled in this study. We evaluated their early postoperative complications and mortality. Postoperative complications included primary graft failure, cerebrovascular accident, mediastinal bleeding, renal failure, low cardiac output syndrome requiring intra-aortic balloon pump or extracorporeal membrane oxygenation insertion, pericardial effusion, and inguinal lymphocele. Follow-up was 100% complete with a mean follow-up duration of 58.4±43.6 months. Results: Early death occurred in three patients (1.3%). The most common complications were pericardial effusion (61.5%) followed by arrhythmia (41.8%) and mediastinal bleeding (8.4%). Among the patients complicated with pericardial effusion, only 13 (5.4%) required window operation. The incidence of other significant complications was less than 5%: stroke (1.3%), low cardiac output syndrome (2.5%), renal failure requiring renal replacement (3.8%), sternal wound infection (2.0%), and inguinal lymphocele (4.6%). Most of complications did not result in the extended length of hospital stay except mediastinal bleeding (p=0.034). Conclusion: Heart transplantation is a widely accepted option of surgical treatment for end-stage heart failure with good early outcomes and relatively low catastrophic complications.
