The isolated coronary ostial stenosis is rare and a critical lesion which requires urgent surgical intervention. Recently direct angioplasty is assumed as a preferable approach to conventional bypass grafting. From Mar. 1990 to Aug. 1993, six patients underwent direct angioplasty in Sejong Heart Institute. The mean age of 6 patients was 48 years [range 37 to 63 and they consisted with 5 females and one male. All had severe angina [class III or IV of short duration [mean 5.3 months and a low incidence of risk factors. Despite the crucial location of the lesion, most patients had well preserved left ventricular function and normal wall motion. We performed direct angioplasty with autologous pericardium via anterior approach except one patient who underwent direct angioplasty and CABG. One patient died 4 hours after angioplasty probably due to acute coronary dissection. The survived 5 patients maintain normal life without symptoms during 26.2 months follow up [range 5 to 47 months .Our preliminary results suggest that angioplasty of isolated coronary ostial stenosis in highly selected patient can be carried out with good results and relatively low operative risks.

Health outcomes are strongly associated with dietary factors. Poor dietary intake increases health risks and can have adverse affects throughout all stages of live and can be passed onto next generations. Korea faces a double burden of nutritional problems. One one side health problems are related to an inadequate diet including underweight, osteoporosis or anemia etc. On the other side the health problems are related to over consumption, including obesity, hypertension, diabetes, cancer, cardiovascular disease and etc. Improving the national health and nutritional status requires adjustments of nutrition policies that have primarily focused on under nutrition, to accommodate all nutrition concerns within the country. Nutrition research specific to Korean people must be promoted to produce scientific evidences on which to base nutrition policies. The creation of a nutrition-specialized institute is an important starting point.

It is difficult to measure the pulse wave in a short time because radial artery position and located depth are different depending on the person. In this paper, the pulse wave measurement system was developed using 3 channel piezoresistive sensor array to detect the most significant pulse wave. Augmentation Index(AI) and Heart Rate(HR) analysis are also available for predicting cardiovascular risks. The developed system is small and easy to use. And it is promising to be used as home healthcare device.

일반적으로 폐질환과 심장 질환이 동시에 발견되었을 때 동시 수술은 술자가 고려해야 되는 사항이 많다. 59세 여자 환자가 우중엽절제술과 이중판막 재치환술과 삼첨판막륜성형술을 동시에 시행 받았다. 동시 수술은 폐와 심장의 병변을 일거에 해소하면서 2차적으로 시행해야 하는 폐절제술 또는 심장수술에 따르는 위험성을 피할 수 있는 장점이 있으며 안전하게 시행할 수 있는 술식이다.

Open heart surgery patients have additional risks arising from the special nature of the operative procedure. And postoperative infections in patients with extracorporeal circulation are associated with high incidence of serious sequelae. To investigate the incidence and organisms of contamination, and the relation between the duration of extracorporeal circulation and contamination, following study was done. Eighty-four of the open heart surgery patients were examined with cultures from the blood and priming solution before and after bypass. 1. Cultures before bypass were sterile, but 2 cases of cultures from the blood and priming solution after bypass were positive, and culture positive group was 5% of all patients. 2. The organisms were Gram-negative, aerobic coliform bacilli; 3. The culture positive group had significantly longer bypass time.

Ginseng has long been used as a functional food or therapeutic supplement and it is empirically known to be safe and nontoxic. During recent decades, a number of in vitro and in vivo experiments, as well as human studies have been conducted to prove the safety of various types of ginseng samples and their components. Clinical trials, case reports, and in vitro and in vivo research articles addressing the safety, toxicity, and other adverse events of ginseng application were selected and reviewed. Patient risks associated with ginseng abuse and misuse such as affective disorder, allergy, cardiovascular and renal toxicity, genital organ bleeding, gynecomastia, hepatotoxicity, hypertension, reproductive toxicity, and anticoagulant-ginseng interaction were reviewed and summarized. There are some cases of patient risk associated with ginseng abuse and misuse depending on patients' conditions although further investigation in more cases is required to clarify these issues.

The purpose of this study was to examine the effects of physical activity on women's health. I conducted literature reviews for meta-analyses and randomized controlled trials with the target diseases including cardiovascular diseases, diabetes, cancers osteoporosis, and pregnancy outcomes. Women who were active had less total mortality and smaller incidence of hypertension, coronary heart diseases, and stroke. Exercise was better than drug therapies in preventing diabetes and effective in preventing colon and breast cancers. Exercise can reduce the risks of falling injury in elderly women. Walking during pregnancy was not harmful to the mothers and their infants, and desirable to prevent the complications of pregnancy or weight gain after pregnancy. Physical activity at work and leisure-time showed similar effects on women's health. Based on these results, moderate-intensity physical activity should be recommended to all women, Resistive, muscle strength, and balance-training exercise also can be recommended. Doctors' advices are effective to make women exercise, especially using handouts or motivational interviewing techniques. It is desirable to recommend to peform other health promotion measures together such as smoking cessation, weight control and diet control.

Lung transplantation is the only treatment option for patients with end-stage lung disease. Although more than 4,000 lung transplants are performed every year worldwide, the standardized protocols contain no guidelines for monitoring during lung transplantation. Specific anesthetic concerns are associated with lung transplantation, especially during critical periods, including anesthesia induction, the initiation of positive pressure ventilation, the establishment and maintenance of one-lung ventilation, pulmonary artery clamping, pulmonary artery unclamping, and reperfusion of the transplanted lung. Anesthetic management according to the special risks associated with a patient's existing lung disease and surgical stage is the most important factor. Successful anesthesia in lung transplantation can improve hemodynamic stability, oxygenation, ventilation, and outcomes. Therefore, anesthesiologists must have expertise in transesophageal echocardiography, extracorporeal life support, and cardiopulmonary anesthesia and understand the pathophysiology of end-stage lung disease and the drugs administered. In addition, communication among anesthesiologists, surgeons, and perfusionists during surgery is important to achieve optimal patient results.

목 적 : 레닌-안지오텐신계가 혈압 조절에 있어서 핵심적인 역할을 한다는 것은 이미 잘 알려진 사실이며, 이 체계의 한 구성 요소인 angiotensinogen을 암호화하는 유전자가 고혈압의 유전적 감수성을 결정하고 심혈관계 합병증 발생에 중요한 역할을 할 것으로 생각된다. 본 연구의 목적은 고혈압 청소년에서 angiotensinogen 유전자 다형을 분석하고, 특정 유전자형이 심혈관계 합병증의 예측 인자가 될 수 있는지를 알아보고자 하였다. 방 법 : 16세에서 17세 사이의 수축기 혈압 140 mmHg 이상이거나 이완기 혈압 90 mmHg 이상인 40명의 고혈압 청소년과 57명의 정상 청소년을 대상으로 하였다. 비만도, 체질량지수를 측정하였고, 안정된 상태에서 수축기, 이완기 혈압을 측정하였다. 호모시스테인, 인슐린, 레닌, 알도스테론, 안지오텐신 전환 효소(angiotensin convering enzyme, ACE)를 측정하였고, polymerase chain reaction (PCR)을 이용하여 angiotensinogen (M235T) 유전자형을 분석하였다. 경부 초음파로 경동맥 내중막 두께와 경동맥 직경을 측정하였고, 이를 이용하여 경동맥의 유순도와 신전도를 구하였다. VP-1000을 이용하여 pulse wave velocity (PWV)와 ankle-brachial index (ABI)를 측정하였다. 유전자 다형별로 각 계측치를 비교, 분석하였다. 결 과 : Angiotensinogen 유전자 다형 분석에서 T/T 군 25명(62.5%), M/T 군 14명(35%), M/M 군 1명(2.5%)로 정상 청소년과 유의한 빈도의 차이가 없었다. 고혈압군에서 인슐린, 레닌, 체질량지수, 비만도에서 세 유전형군 간의 유의한 차이가 나타났으나, 경동맥 내중막 두께와 직경, 신전도, 유순도, PWV, ABI에서는 세군 간의 유의한 차이는 없었다. 결 론 : Angiotensinogen의 특정 유전자 다형과 심혈관계 합병증간의 유의한 연관성은 없었으나, 본 연구의 고혈압 청소년 대상이 적었으므로 더 많은 연구가 필요할 것으로 생각된다.

배경: 면역저하 환자에게 발생하는 폐 합병증은 흔히 치명적이다. 폐생검술과 같은 침습적인 진단 술기의 위험도 때문에 일반적으로 임상 양상과 방사선 영상 소견에 근거하여 경험적인 치료가 적용된다. 그러나 최근 수술 술기와 수술 전후의 환자 관리의 발전으로 인해 술기와 연관된 위험도는 줄어든 실정이다. 이에 폐합병증을 동반한 심한 면역저하 환자에서 시행된 폐생검술의 위험성 및 유효성에 대하여 전향적으로 분석하였다. 대상 및 방법: 1996년 6월부터 1999년 12월까지 폐합병증을 동반한 면역저하 환자 42명에서 43례의 폐생검술을 실시하였다. 면역저하는 다음과 같이 정의하였고(1, 혈액학적인 질환으로 인해 화학요법이나 다른 치료를 동반하여 받은 경우, 2. 이식 수술 후 면역 억제제를 복용하는 경우, 3. 1 개월 이상의 스테로이드 복용, 4. 원발성 면역결핍 질환), 이상의 면역저하 환자에서 새로운 폐합병증을 동반하고 1 주간의 경험적 치료에 호전이 없거나 급속하게 진행되는 경우를 대상으로 하였다 기저 질환은 혈액학적 질환(31명), 이식 수술 환자(3명), 고형암으로 인한 화학요법(2명)등이었으며 수술은 개흉술이나 video-aided thoracoscopic surgery (VATS)를 통하여 이루어 졌다.
