Misoprostol (Cytotec) is a prostaglandin E, analog used in prevention of nonsteroidal anti-inflammatory drugs induced gastric ulcer and has a uterotonic effect. It has been used to terminate pregnancy at any stage by promoting uterine contractions and for ripening the cervix before induced labor or abortion. Recently, it is known to reduce postpartum hemorrhage. Very little experience has been reported acute misoprostol toxicity in contrast with its usages. We have experienced a case of acute toxicity of misoprostol used for management of postpartum hemorrhage. We report this case with a review of literatures.

목적 : 본 연구의 목적은 조기분만의 위험성이 있는 임산부에게 투여된 덱사메타손이 산모와 태아의 부신 억제를 야기 시킬 수 있는 지에 대하여 평가하고자 하였다. 연구 방법 : 임신하지 않은 여성 10명을 대상군으로 하여 기초 혈청 코르티솔 수치와 저용량 (1 g) 부신피질자극 호르몬 자극 검사 후 혈청 코르티솔 수치를 측정하였다. 조기진통이 있는 10명의 여성에게 1주 간격으로 저용량 (1 g) 부신피질자극호르몬 자극 검사 시행하였으며, 첫 번째는 입원 시 시행하였다. 처음 저용량 부신피질자극호르몬 자극 검사 후, 덱사메타손 5 mg을 12시간 간격으로 2일간 시행하였다. 혈청 코르티솔 수치는 각각 기초 수치 (부신피질자극호르몬 자극 검사 시행 전)와 자극된 수치 (부신피질자극호르몬 자극 검사 30분 뒤)를 측정하였다. 결과 : 총 대상 환자은 10명이었으며, 모든 환자에서 정상 기초 코르티솔 수치와 자극된 코르티솔 (처음 부신피질자극호르몬 자극 검사 후)를 나타내었다. 부신 억제가 발생한 환자는 총 5명이었고 나머지는 부신 억제가 발생하지 않았다. 부신 억제가 발생된 집단에서는 평균 기초 코르티솔 수치는 덱사메타손 투여 전 38.52 g/dL에서 1주기 덱사메타손 투여 후 1주일 뒤에는 33.26 g/dL로 감소하였다. 또한 부신 억제가 발생된 집단서는 평균 자극된 코르티솔 수치는 덱사메타손 투여 전 46.40 g/dL에서 1주기 덱사메타손 투여 후 1주일 뒤에는 45.02 g/dL로 감소하였다. 결론 : 조기분만의 위험성이 있는 여성에게 1주기의 덱사메타손을 투여 시 다소 부신 기능 억제를 초래할 수 있지만 부신피질 기능저하증은 초래하지 않으며, 태아나 산모의 부신 기능 장애를 야기 시키지는 않을 것이다. Objective : The aim of this study was to determine whether 1 cycle of dexamethasone administration to women at risk of preterm delivery causes adrenal suppression Methods : Nonpregnant ten control subjects were checked baseline cortisol and stimulated cortisol level after low-dose (1 g) ACTH stimulation test. Ten women at risk of preterm delivery had two weekly low-dose (1 g) ACTH stimulation tests with the first one at admission. Immediately after the first ACTH stimulation test, we gave each women a 5 mg dexamethasone dose intramuscularly and repeated it 12 hours later for two days. Serum cortisol levels were measured before (baseline) and 30 minutes after ACTH administration. Results : All ten subjects had normal baseline and stimulated cortisol levels for the first ACTH stimulation test. The adrenal suppressed Group was composed of 5 patients. But the remainders was not suppressed. Mean baseline serum cortisol levels decreased from 38.52 g/dL (before dexamethasone) to 33.26 g/dL (1 week after 1 cycle of dexamethasone) in adrenal suppressed Group. The mean stimulated cortisol levels also decreased from 46.40 g/dL (before dexamethasone) to 45.02 g/dL (1 week after 1 cycle of dexamethasone) in adrenal suppressed Group.Conclusions : Antenatal administration of 1 cycle dexamethasone produced slightly adrenal suppression, but no adrenal insufficiency, in some women at risk of preterm delivery and may be harmless to maternal and fetal adrenal function.

차량 및 산업설비 폐열회수용 열전발전시스템의 최적 열교환 시스템에 관한 실험적 연구
정재훈(Chung, Jae-Hoon),김우철(Kim, Woo-Chul),이진호(Lee, Jin-Ho),류태우(Yu, Tae-U.) 한국신재생에너지학회 2008 한국신재생에너지학회 학술대회논문집 Vol.2008 No.05
A large part of the overall industrial energy is dissipated as waste heat despite of much development in the utilization of thermal energy. A mean efficiency is reported to be only around 30 to 35%. The existing waste heat recovery technology has reached its limit and consequently, the development of a new technology is necessary. Improving efficiency using thermoelectric technology has recently come into the spotlight because of its unique way to recover thermal energy. In fact, thermoelectric generator directly converts thermal energy into electric energy by a solid state without any moving parts. Futhermore remarkable improvement in the thermoelectric energy conversion efficiency has been achieved. In this study, a thermoelectric generator was made using commercialized thermoelectric modules. With thermoelectric modules attached on a duct surface, hot air was blown into the duct using a hot air blower. On the other side of the module, a water jacket was attached to cool the module. With different air inlet temperatures and water flowrates, the electrical power of the thermoelectric generator was measured.

N/A Reduced amniotic fluid volume generally leads to a poor perinatal outcome, especially when it is observed in the second trimester. The recent obstetric literatures have been reporting on various applications of amnioinfusion in the diagnostic, prophylactic and therapeutic management of oligohydroamnios. We experienced two cases of amnioinfusion, which were used to diagnose or to manage the midtrimester oligohydroamnios and we report them with a brief review.
