Background: Minimally invasive direct coronary artery bypass surgery(MIDCAB) has been increasing in interest along with the new techniques in myocardial immobilization for easier and safer procedures. Until the opening of the era of new techniques, adequate accuracy and good patency of grafts were debatable. Our experiences of MIDCAB were studied according to the stages of technical developments. Material and Methods: Since March 1996, 55 patients have undergone MIDCAB procedures. The patients of off-pump CABG(no cardiopulmonary bypass under full sternotomy) were excluded from the study. In the early experience(Stage I), a left anterior small thoracotomy through the left parasternal incision was performed(n=6); then an approach through the lower partial sternotomy was used(Stage II, n=33); and recently, a chest wall elevator for harvesting the internal thoracic artery and the foot plate for myocardial immobilization have been used(USSC, Norwalk, CT)(Stage III, n=16). Result: The surgical procedures of four patients in the Stage II group have been converted to conventional bypass because of the deeply seated left anterior descending coronary artery in two patients, fracture of the calcific lesion in the right coronary artery in one patient, and a cardiogenic shock during hypothermia in the other patient with ventricular dysfunction. Two patients in stage II experienced symptomatic recurrences after surgery and restenosis was verified on angiocardiography. They were managed by interventional procedures. All the other patients were doing well without symptoms, except one patients in Stage II who underwent PTCA procedure for a lesion in the circumflex artery during the follow up period. Conclusion: The new and specialized devices are essential to the development of MIDCAB surgery. MIDCAB and the hybrid procedures in multi-vessel disease are on the way to further development. So far, our experience is limited only to a single device among the many new devices for the purpose.

Objectives: This study aimed to investigate the seasonal variation in stroke types, ischemic stroke subtypes, stroke risk factors and Sasang constitutions. Methods: 226 patients with acute stroke within 14 days onset were included, who were admitted to Kyunghee Oriental Medical Center from November 2005 to October 2006. The year was subdivided into four parts: spring (March-May); summer (June-August); fall (September-November); and winter (December-February). Stroke types, ischemic stroke subtypes, stroke risk factors and Sasang constitutions in the four groups were examined. Results: Ischemic stroke was most frequent in summer, whereas hemorrhagic stroke was most frequent in winter. There was no significant difference in seasonal variation of stroke. The frequency of ischemic heart disease among stroke risk factors was significantly high in spring (p=0.031). The frequency of hypertension, diabetes mellitus, atrial fibrillation, and hyperlipidemia did not differ among seasons. There was no significant difference in Sasang constitution among seasons. Frequency of small vessel occlusion was highest in summer. Large artery atherosclerosis was frequent in spring and summer,but seasonal variation of ischemic stroke subtypes did not show statistical difference. Conclusion: Acute stroke demonstrates seasonal characteristics according to stroke types, ischemic stroke subtypes, risk factors for stroke, and Sasang constitutions. These results have important clinical implications in stroke prevention.

Objectives : This study investigated the clinical effect of a drinking habit in acute stroke patients. Methods : 409 acute stroke patients were included from October 2005 to October 2006. Patients were hospitalized within 14 days after the onset of stroke at DongGuk University International Hospital, Kyungwon University In-cheon Oriental Medical Hospital, or Department of Cardiovascular and Neurologic Diseases (Stroke Center), Kyung Hee University Oriental Hospital. We investigated general characteristics, drinking habit, and stroke subtype by TOAST classification. Results : Among drinking subjects, hemorrhagic stroke was more frequent than ischemic stroke (odds ratio 3.04), and less in small vessel occlusion than others (odds ratio 1.84). Ischemic stroke was associated with a longer (30 yrs) drinking habit than hemorrhagic stroke. Conclusions : To acquire more concrete conclusions on this theme, we need further and larger scale research.

Transgenic animals have been widely used for developmental biology studies, as disease models, and even in industry such as transgenic bioreactor animals. For transgenic birds, quail has the great advantages of small body size, short generation time, and frequent egg production. To date, retroviral or lentiviral transduction has been used to generate transgenic quail for various purposes. However, the efficiency of transgenic offspring production with these methods is relatively low and viral vector usage has safety issues. Unfortunately, non-viral transgenesis has not been established in quail due to a deficiency of stem cell and germ cell culture systems. In this study, we established a direct in ovo lipofection method that could be used to create transgenic quail without germline-competent cells or viruses. To optimize the injection stage during embryo development, the liposome complex (containing piggyBacCMV-GFP and transposase plasmids) was introduced into an embryonic blood vessel at 50 hr, 55 hr or 60 hr. GFP expression was detected in various tissues (heart, kidney, liver and stomach) on day 12 of incubation under a fluorescence microscope. Additionally, GFP-positive cells were detected in the recipient embryonic gonads. In conclusion, the direct in ovo lipofection method with the piggyBac transposon could be an efficient and useful tool for generating transgenic quail.

Background: For the surgical management of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA), there have been various techniques that reduce the tension and kinking of the coronary artery during reimplantation to the aorta. The aim of this study is to describe the results of our modified technique of coronary reimplantation for the treatment of ALCAPA. Methods: Between October 2003 and February 2011, seven patients underwent coronary reimplantation with the modified technique (tubing formation with the sinus wall of the pulmonary artery and trapdoor formation at the site of implantation in the aorta). The median follow-up duration was 52 months (range, 4 to 72 months). Clinical outcomes and serial echocardiographic data were reviewed. Results: There was no mortality. One patient had a small amount of cerebral hemorrhage postoperatively and improved without any sequelae. Another patient had left diaphragm palsy and underwent diaphragm plication. Follow-up echocardiogram showed that all patients had normal ventricular function without chamber enlargement. Conclusion: Our modified technique (tubing formation with the sinus wall of the pulmonary artery and trapdoor formation at the site of implantation in the aorta) demonstrated successful clinical outcomes. We conclude that this surgical technique can be a potential alternative for the treatment of ALCAPA.

목 적 : HSP는 주로 소혈관을 침범하는 혈관염으로 대개 자연적으로 치유되지만 장기적 예후는 신장 침범의 정도에 달려 있으므로 신장 침범의 위험인자를 예측하고 예방하는 것이 중요하다. 이에 본 연구는 증상을 완화하기 위해 사용한 스테로이드가 HSP에서 신장 침범을 줄일 수 있는지를 알아보고자 하였다. 방 법 : 1993년 1월부터 2006년 12월까지 충북대학교병원 소아과에서 HSP로 진단 받은 환아를 대상으로 하여 스테로이드 사용 유무와 사용 기간, 지속성 자반의 유무에 따른 신장 침범의 유무와 정도를 분석하였다. 결 과 : 스테로이드 사용 유무와 사용 기간에 따른 신장 침범 빈도와 신장 침범 기간에는 유의한 차이가 없었다. 스테로이드의 사용 여부에 따른 신장 침범 양상을 보았을 때, 스테로이드를 사용한 경우에는 혈뇨가 많이 나타나고 사용하지 않은 경우에는 단백뇨가 많이 나타나는 경향을 보였으나 통계적으로는 유의한 차이가 없었다. 스테로이드의 사용과 자반의 지속성과는 유의한 관계가 없었다. 반면에 10일 이상의 지속성 자반이 있는 경우에 신장 침범이 유의하게 많은 것으로 나타났으며, 신장 침범의 기간도 지속성 자반이 있는 경우에 증가하는 것으로 나타났다. 결 론 : HSP로 진단받은 환아들에게 복통이나 관절통 등으로 스테로이드를 사용한 후 신장 침범의 유무를 비교해 본 결과, 스테로이드의 사용 여부와 사용 기간과는 유의한 결과를 보이지 않으므로 신장 침범에 대한 스테로이드의 예방효과는 없는 것으로 생각된다. 또한, 스테로이드 치료의 적응증이 아닌 자반의 지속성이 오히려 신장 침범의 유무와 기간과 관계있다는 사실은, 스테로이드가 신장 침범의 예방효과가 없음을 뒷받침해 주고 있다.
