석청에 포함된 grayanotoxin에 의해 독성 작용이 나올 수 있으며, 이러한 독성 작용은 일반적으로 24시간 이내 저절로 회복된다. 최근에 본 저자들은 석청 복용 후 발생한 심실빈맥을 경험하였기에 보고하는 바이다. 49세 남자가 호흡곤란으로 내원하였으며, 내원당시 분당 40회 정도의 동성 서맥이 관찰되었고, 수액을 투여하던 중 심실 빈맥이 발생하였다. 항부정맥제를 투여 후 정상 동율동으로 전환되었으며, 특별한 이상 없이 4일 후 퇴원하였다. Mad-honey intoxication caused by the consumption of honey producted from the nectar of rhododendrons. The grayanotoxins cause the intoxication. The toxic effects of mad-honey poisoning are rarely fatal and generally last for no more than 24 hours. We experienced one case, a 49 years-old man who presented with dyspnea after ingestion of mad-honey. He showed marked sinus bradycardia with < 40 beats per minute on admission. The cardiac rhythm was changed to ventricular tachycardia immediately. These features resolved completely in 24 hours with continuous infusion of amiodarone(600 mg per day) and fluids. We report the case of intoxication of mad-honey as a presentation of fatal cardiac arrhythmia.

재발하는 심실 빈맥으로 내원한 환자에서 Sheehan 증후군을 진단하였고, 적절한 호르몬 보충 치료 후 심전도 이상이 정상으로 회복된 예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Torsades de Pointes is a form of polymorphic ventricular tachycardia that is associated with prolongation of QT intervals, characterized by QRS complexes of progressively changing ampulitude and cyclic length, giving the appearance of oscillations around the baseline. A 77 years-old woman was presented with hypotention and arrhythmia. Twenty four-hour ECG showed typical episodes of torsades de pointes with QT prolongation. This arrhythmia was controlled by isoproterenol and magnesium infusion, but it was not disappeared. She was diagnosed as Sheehan's syndrome by past history, anterior pituitary stimulation test and empty sella on CT scan. After hormone replacement treatment, Prolonged QT interval was normalized and polymorphic ventricular tachycardia has not recurred. We report a case of torsades de pointes associated with Sheehan's syndrome

김영동,강원찬,김남오,김형곤,김병철 조선대학교 에너지.자원신기술연구소 2004 에너지·자원신기술연구소 논문지 Vol.26 No.1

In this paper, digitally controlled electronic ballast for the HID lamps driven by proposed frequency conversion method is described. This electronic ballast consists of a buck converter, a low frequency square wave full bridge inverter, a high voltage pulse generator for the lamp ignition, an over current protection circuit and an 8-bit microcontroller. The fuzzy logic digital control operation is carried out by the 8-bit microcontroller. In spite of the limited control bandwidth caused by low operation speed of the 8-bit microcontroller, the good control performance for the constant lamp current in the warm-up period is obtained using the proposed frequency conversion driving method. The HID lamp is controlled in a constant current mode during the lighting warm up process and is controlled in a constant power mode during lighting steady state. A controlled variable power mode is used to extend the lamp lifetime.

Recurrent mandibular dislocation is frequent morbidity of temporomandibular joint relatively. There are many etiologic causes in TMJ disorders but, difficult to find obvious one. Various treatment methods have been utilized for a mandibular dislocation. It is categorized into two groups broadly - nonsurgical or surgical methods. The basic rationale of the surgical method is to allow free movement of the condyle by reducing height of articular eminence or to limit anterior excessive movement of the condyle by increasing height of articular eminence or soft tissue anchoring procedure. In this case, 69 year-old woman was treated by augmentation of the articular eminence with mandibular symphysial bone graft leading to osteosynthesis without difficulty. As a result, favorable postoperative outcome was obtained functionally without any complication or recurrence.

홍성윤,김정민,김소영,이수정,오은실,양서인,김화실,김남초 병원간호사회 2006 임상간호연구 Vol.11 No.2

Purpose: The present study purposed to compare the hand washing effect of 7.5% powidone-iodine, which is used in the operation room of C university hospital in Seoul, with that of Ethyl alcohol-CHG mixture recommended by the US Association of Operating Room Nurses (2002) and to adopt a more effective hand disinfectant. Method: In a quasi-experimental design, 48 medical staff who participated in operations during the period from November 2004 to February 2005 had hand washing using the two kinds of hand disinfectants: 7.5% povidone-iodine and the ethyl alcohol-CHG mixture. Their palms were swabbed and cultured just after hand washing and again after taking dff sterile gloves after the operation. The number of colonies from the two occasions were counted and compared. Result: The number of general bacillus increased significantly in the group using 7.5% povidone-iodine compared to that in the group using the ethyl alcohol-CHG mixture. The number of general bacillus increased signficantly in doctors compared to that in nurses. The factors affecting the increase of the number of general bacillus were disinfectants and medical personnel. The number of general bacillus was expected to increase 9.41 times with 7.5% povidone-iodine than with the ethyl alcohol-CHG mixture and 14.87 times in doctors than in nurses. Conclusion: This study shows that the ethyl alcogol-CHG mixture has a stronger hand disinfection effect than 7.5% povidone iodine. Thus we need to change the hand disinfectant used in operating rooms as soon as possible in order to minimize the infection of wounds resulting from operations.

중합효소연쇄 반응법에 의한 인형거대세포바이러스(human cytomegalovirus)의 신속한 검출

김의종,오명돈,박기호,신형식,이환종,김남중,최강원 대한감염학회 1996 감염 Vol.28 No.4

목 적 : 인형거대세포바이러스(HCMV)는 면역 저하 환자에서 폐렴, 망막염, 간염 등 치명적인 감염증의 원인이다. 전통적인 세포 배양법으로 HCMV를 분리하기까지는 1주에서 4주가 걸리므로 이 바이러스에 의한 질환이 의심되는 경우 신속한 진단법을 이용한 진단이 바람직하다. 저자들은 한국에서 분리되는 야생주 HCMV를 검출하는데 중합효소 연쇄 반응법을 이용할 경우의 진단적 유용성을 알기 위하여, 전통적인 세포배양법으로 HCMV가 분리된 검체를 이용하여 중합효소 연쇄 반응법의 특이도와 민감도를 평가하였다. 방 법 : 국내 야생주 HCMV 15주, 그리고 전통적인 바이러스 배양법으로 HCMV가 분리된 소변 15검체를 대상으로 중합효소 연쇄 반응을 실시하였다. 중합효소 연쇄 반응은 Towne주의 immediate early antigen의 유전자에서 유리된 primer MIE와 AD169주의 immediate early antigen의 유전자에서 유리된 primer IE를 이용하였다. 증폭 산물은 겔 전기영동 후 EtBR으로 염색하여 자외선 하에서 관찰하였다. Primer IE에 의한 증폭산물은 또한, DNA blot hybridization 방법으로 확인하였다. 결 과 : 1) 국내 HCMV 야생주 15주를 대상으로 중합효소 연쇄 반응을 한 결과 primer IE를 이용한 경우에는 100%(15/15)에서 177bp의 증폭 산물이 관찰되었고, 이들 증폭 산물은 모두 probe IE와 보합 결합되었다. primer MIE를 이용한 경우에는 93%(14/15)에서 435bp의 증폭 산물이 관찰되었다. 2) 세포 배양법으로 HCMV가 분리된 소변 15검체를 대상으로 primer IE를 이용하여 중합효소 연쇄 반응을 한 결과 direct gel analysis 법으로는 73%(11/15)에서, 보합 결합법으로는 87%(13/15)에서 관찰되었다. Primer MIE를 이용한 경우에는 direct gel analysis법으로 87%(13/15)에서 435bp의 증폭 산물이 검출되었다. 결 론 : Primer IE와 MIE를 이용한 중합효소 연쇄 반응법은 국내 야생주 HCMV를 신속히 검출하는데 유용한 검사법이다. Background : Human cytomegalovirus(HCMV) can cause pneumonitis, hepatitis, retinitis and other serious diseases in the immunocompromised patients. It takes 1 to 4 weeks to diagnose HCMV infection by conventional virus culture. Therefore, when HCMV diseases are suspected, a rapid diagnostic method such as polymerase chain reaction(PCR), antigen assay or shell vial culture is desirable. We evaluate the sensitivity and specificity of a PCR for the rapid detection of HCMV wild strains in Korea. Methods : We used 2 sets of primers ; primer IE and primer MIE derived from the sequence for immediate early gene of AD169 strain and Towne strain, respectively. Fifteen clinical isolates of HCMV, suspended in MRC-5 cells, were amplified by PCR. Fifteen urine specimens which were positive for HCMV by conventional virus culture were also amplified. Amplification products were analyzed by polyacrylamide gel electrophoresis. The products from PCR with primer IE were also identified by DNA blot hybridization. Results : PCR using primer IE gave the PCR products in all of the 15 HCMV wild strains. All of these were hybridized with probe IE. When primer MIE were used, 93%(14/15) of the wild strains showed amplified bands by direct gel analysis. When the urine specimens were amplified by PCR with primer IE, amplified bands were seen in 73%(11/15) by direct gel analysis ; 87%(13/15) by hybridization method. When primer MIE were used, 87%(13/15) of the urine specimens showed the PCR products by direct gel analysis. Conclusion : Polymerase chain reaction with primer IE and MIE may be a specific and sensitive diagnostic method for rapid detection of HCMV wild strains in Korea.
