Purpose: The purpose of this study is to present extended indications for the use of arterialized venous flaps in reconstructing soft tissue, tendon, nerve, blood vessel, and composite tissue defects of the hand of various sizes based on researches and clinical experiences of the authors. Moreover, procedures to achieve complete flap survival and postoperative results are presented. Materials & methods: This study is based on 154 cases of arterialized venous flaps performed to reconstruct the hand during the past 11 years. The most common cause of injury was industrial accidents with 125 cases. One hundred thirty patients or 84% of the cases had emergency operation within 2 weeks of the injury. The flaps were categorized depending on the size of the flap. Flaps smaller than $10\;cm^2$ were classified as small (n=48), those larger than $25\;cm^2$ classified large (n=42) and those in between medium (n=64). Classified according to composition, there were 88 cases (57.1 %) of venous skin flaps, 28 cases of innervated venous flaps, 15 cases of tendocutaneous venous flaps, which incorporated the palmaris longus tendon, for repair of extensor tendons of the fingers, and 17 cases of conduit venous flaps to repair arterial defect. There were 37 cases where multiple injuries to multiple digits were reconstructed. Moreover, there were 6 cases of composite tissue effects that involved soft tissue, blood vessels and tendons. The donor sites were ipsilateral forearm, wrist and thenar area, foot dorsum, and medial calf. The recipient sites were single digit, multiple digits, first web space, dorsum and palm of hand, and wrist. Results: There were seven cases (4.5%) of emergent re-exploration due to vascular crisis, and 3 cases of flap failure characterized by more than 50% necrosis of the flap. The survival rate was 98.1 % (151/154). In small flaps, an average of 1.01 afferent arteries and 1.05 efferent veins were microanastomosed, and in large flaps, an average of 1.88 afferent arteries and 2.19 efferent veins were anastomosed. In 8 cases where innervated flaps were used for reconstructing the palm of the hand, the average static two-point discrimination was $10\;(8{\sim}15)\;mm$. In 12 cases where tenocutaneous flaps were used, active range of motion at the proximal interphalangeal joint was 60 degrees, 20 degrees at the distal interphalangeal joint, and 75 degrees at the metacarpophalangeal joint. Conclusion: We conclude that the arterialized venous flap is a valuable and effective tool in the reconstruction of hand injuries, and could have a more comprehensive set of indications.

Objective: The antiplatelet agent aspirin has been widely used for treating atherosclerosis in western medicine, and its efficacy has been proven in cardiac and extracardiac vascular diseases. On the other hand, Hyeolbuchukeo-tang has been widely used for treating blood stasis syndrome in traditional medicine. Therefore we investigated whether Hyeolbuchukeo-tang could have a synergic effect along with aspirin. Methods & Materials: Male $ApoE^{(-/-)}$ mice were randomly divided into three different experimental groups: a non-treated group(Control group), an aspirin-treated group(AP group), and an aspirin with Hyeolbuchukeo-tang-treated group(APH group). The control group was fed only an atherogenic diet, the AP group an atherogenic diet plus Aspirin 5 mg/kg, and the APH group an atherogenic diet plus Aspirin 5 mg/kg with Hyeolbuchukeo-tang 100 mg/kg. We investigated plasma lipid with liver function test, and performed the histological investigation of liver and abdominal aorta. Results: 1. We investigated photomicrographic changes of liver and abdominal aorta tissue. They showed that histological injury of aorta and lipid accumulations of the liver were lower in the AP and APH groups than in the control group. 2. In the APH group, plasma triglyceride levels were significantly lower than those in the control and AP groups. 3. There were no differences in aspartate aminotransferase and alanine aminotransferase levels among the control, AP and APH groups. Conclusion: The above results show that a combined treatment of Hyeolbuchukeo-tang and aspirin has a somewhat synergic effect in terms of inhibiting vessel injury and decreasing lipid deposits on liver cells without liver toxicity.

본 연구에서는 free radicals의 산화적인 손상에 의한 세포사멸에 있어서 녹차성분의 하나인 (-)epigallocatechin gallate의 억제효과를 규명하였다. 우선 radicals 소거작용에 있어서 (-)epigallocatechin gallate는 탁월한 항산화력을 발휘하였다. 혈관손상과 직결되는 혈관내피세포를 이용하여 hydroxyl radical의 $H_2O$$_2$에 의한 산화적인 손상을 유발시켜 세포생존율을 조사하였는데, (-)epigallocatechin gallate는 100 $\mu\textrm{m}$ 이하의 농도에서는 그 자체 독성이 없었고 $H_2O$$_2$의 산화적 독성효과를 경감시키는 것으로 나타났다. 그러나 flavone인 apigenin은 고농도에서 독성을 가지며 radical 소거활성이 미약하고 $H_2O$$_2$의 산화독성은 경감시키지 못하였다. 다양한 세포사멸 검출법을 이용하여 세포 및 세포핵의 형태학적 양상을 조사한 결과, 0.25mM $H_2O$$_2$에 의한 24시간 이내의 세포죽음은 세포사멸현상에 의하여 초래되었다. 그러나 이러한 세포사멸과정을 겪고 있는 혈관내피세포에 50 $\mu\textrm{m}$ (-)epigallocatechin gallate를 처리한 경우에 세포핵의 응축이나 DNA fragmentation은 사라지고 세포사멸작용을 억제시키는 효과를 보여주었다. 예상한 바와 같이 apigenin의 flavone은 세포사멸 억제효과를 나타내지 못하였다. (-)Epigallocatechin gallate는 녹차에 함유된 catechins의 하나로서 free radicals의 산화적 손상에 의한 세포사멸에 있어서 탁월한 방어적 인 세포생리학적인 기능을 지니고 있으며, 혈관노화 및 혈관손상과 함께 유발되는 세포사멸성 심혈관질환의 예방과 치료에 기능성 식품 신소재로서 활용될 수 있으리라 본다.

Background and Objective: Atherosclerosis is a diffuse, systemic disease that affects the coronary, cerebral, and peripheral arterial trees. Clopidogrel is widely used antiplatelet agent and its efficacy has been proven in cardiac and extracardiac vascular diseases, but it has several side effects. Therefore we investigated whether Sopunghwalhyeoltang, which is widely used for treating the blood stasis syndrome in traditional medicine, could decrease the side effect of antiplatelets and have a synergic effect. Methods & Materials: Male $ApoE^{(-/-)}$ mice were randomly divided into three different experimental groups, non-treated group (Control group), clopidogrel-treated group (CP group) and clopidogrel with Sopunghwalhyeol-tang treated group (CPS group). The control group was fed with only an atherogenic diet, the CP group an atherogenic diet plus clopidogrel 25mg/kg and the CPS group an atherogenic diet plus clopidogrel 25mg/kg with Sopunghwalhyeol-tang 100 mg/kg. We investigated plasma lipids with liver function test, and performed a histological investigation of liver and abdominal aorta. Results: 1. Photomicrographs of liver and abdominal aorta tissue showed lower histological injury and lipid accumulation in the CP and CPS groups than those in the Control group. 2. In the CPS group, plasma triglyceride level was significantly lower than in the Control and CP groups. 3. In the CPS group, the plasma aspartate aminotransferase (AST) level was significantly lower than in the CP group. Conclusions: The above results shows that a combined treatment of Sopunghwalhyeol-tang and clopidogrel have a synergic effect through inhibiting vessel injury and decrease the side effects of clopidogrel alone.

급성호흡곤란증후군 (acute respiratory distress syndrome)을 포함한 급성폐손상의 기전을 산화성스트레스와 연관하여 알아보기 위하여 본 연구를 시행하였다. N-nitroso-N-methylurethane (NNNMU)은 실험동물에 있어서 사람에서 보이는 ARDS와 유사한 병리학적인 소견을 보이므로 ARDS의 모델로 사용된다. 본 연구에서는 흰쥐에서 NNNMU로 급성폐손상을 유도한 뒤 이를 Lung weight/Body weight ratio, 폐포세척액(BAL)내의 단백함량을 측정하여 확인하고, 동시에 호중구의 침윤에 의한 산소기형성, 이에 따른 산화성스트레스를 확인하기 위하여 BAL 내의 호중구수의 산정 및 폐장의 MPO 활성도를 측정하였다. 동시에 광학현미경, 전자현미경 및 세포화학적 전자현미경법을 이용하여 호중구에 의한 급성폐손상, 호중구의 침윤 및 미세구조의 변화 및 산소기의 생성을 확인하였다. 대조군에 비하여 NNNMU를 투여한 흰쥐에서는 BAL 내의 단백질이 증가하고 BAL 내의 호중구의 증가, 폐장의 MPO 활성도의 증가로 호중구의 침윤이 증가함을 관찰하였다. 광학현미경상 호중구의 침윤, 폐포내 호중구의 유입 및 vascular cuffing 등이 관찰되었다. 전자현미경 소견상 제2형 폐포세포는 산화성 스트레스의 전형적 소견을 보이고 조직의 손상은 호중구에 의한 손상으로 생각되었으며 세포화학적 전자현미경법으로 산소기의 생성이 증가됨을 확인하였다. 이러한 결과들을 종합할 때 NNNMU에 의한 급성폐손상은 호중구의 산소기 생성에 의한 산화성스트레스에 의한 것으로 생각되었다.

배경: 폐 이식 수술은 호흡부전을 동반한 말기 폐질환 환자에서 유용한 치료방법 중의 하나로 본원에서는 1996년 국내에서 처음으로 일측 폐 이식 수술을 성공한 이래로 현재까지 재 이식 2예를 포함한 총 13예의 폐 이식 수술을 시행하였다. 저자 등은 그동안 환자들의 수술성적 및 합병증, 생존율 등을 분석하고자 하였다. 대상 및 방법: 1996년 7월부터 2005년 7월까지 영동세브란스병원 흉부외과에서 폐 이식을 시행받은 13예, 11명의 환자(2명은 재 이식환자)를 대상으로 후향적으로 임상기록지를 분석하였다. 결과: 남녀비는 9:4, 평균연령은 $45.2{\pm}10.7$세(범위 $25{\sim}59$세)였으며, 폐기종 및 만성폐쇄성 폐질환이 5예로 가장 많았고, 동맥관 개존증으로 인한 아이젠맹거 증후군 2예, 폐섬유증, 폐고혈압, 림프관 평활근종증, 기관지확장증이 각 1예였다. 조기 합병증으로는 출혈, 이식 폐 부전, 감염이며 후기 합병증으로는 감염 및 이식 후 림프증식증이었다. 조기사망 3예를 제외한 평균생존기간은 16.5개월($2{\sim}60$개월)이었다. 재 이식 2예는 이식 폐의 기능 부전에 의하여 각각 첫 이식 후에 2주, 13개월째 시행 받았다. 결론: 폐 이식 수술 후 장기성적을 향상시키기 위해서는 수술술기의 향상뿐만 아니라 수술 후 집중적인 환자관리를 통하여 합병증을 조기에 발견하고 필요한 내과적, 외과적 처치를 즉시 시행하는 것이 예후에 좋은 영향을 미칠 것으로 생각된다.

매립혈액투석카테터 삽입을 위한 접근로 선택에서 쇄골하정맥은 이후에 동정맥루 접근로 형성을 위해 가능한 사용을 피하는 경로이다. 그러나 반복적 삽관으로 접근 가능한 정맥이 소진되거나 기대여명이 길지 않고 응급 투석이 필요한 경우 쇄골하정맥을 선택할 수 있다. 그러나 쇄골하정맥을 통한 혈액투석카테터 삽입에는 기술적인 어려움이 있다. 쇄골하정맥은 종종 상대정맥과 직각을 형성하여 굵은 혈관초삽입시 혈관 손상을 초래할 수 있다. 상지 거상 상태에서 혈관초를 삽입하는 방법은 각도를 완만하게 유도하여 이러한 문제를 극복하는데 도움을 줄 수 있다. 고식적앙와위 자세로 시술 중 상대정맥 손상이 있었던 환자와 연달아 내원하여 상지 거상 후 안전하게 혈액투석카테터를 삽입한 환자의 각각의 증례를 통해 상지 거상법이 도움이 될 수 있음을 보고하고자 한다.

Backgrounds : Because ventilator-induced lung injury is partly dependent on the intensity of vascular flow, we hypothesized that hypothermia may attenuate the degree of such an injury through a reduced cardiac output. Methods : Twenty-seven male Sprague-Dawley rats were randomly assigned to normothermia ($37{\pm}1^{\circ}C$)-injurious ventilation (NT-V) group (n=10), hypothermia ($27{\pm}1^{\circ}C$)-injurious ventilation (HT-V) group (n=10), or nonventilated control group (n=7). The two thermal groups were subjected to injurious mechanical ventilation for 20 min with peak airway pressure 30 cm $H_2O$ at zero positive end-expiratory pressure, which was translated to tidal volume $54{\pm}6\;ml$ in the NT-V group and $53{\pm}4\;ml$ in the HT-V group (p>0.05). Results : Pressure-volume (P-V) curve after the injurious ventilation was almost identical to the baseline P-V curve in the HT-V group, whereas it was shifted rightward in the NT-V group. On gross inspection, the lungs of the HT-V group appeared smaller in size, and showed less hemorrhage especially at the dependent regions, than the lungs of the NT-V group. [Wet lung weight (g)/body weight (kg)] ($1.6{\pm}0.1$ vs $2.4{\pm}1.2$ ; p=0.014) and [wet lung weight/dry lung weight] ($5.0{\pm}0.1$ vs $6.1{\pm}0.8$ ; p=0.046) of the HT-V group were both lower than those of the NT-V group, while not different from those of the control group($1.4{\pm}0.4$, $4.8{\pm}0.4$, respectively). Protein concentration of the BAL fluid of the HT-V group was lower than that of the NT-V group($1,374{\pm}726\;ug/ml$ vs $3,471{\pm}1,985\;ug/ml$;p=0.003). Lactic dehydrogenase level of the BAL fluid of the HT-V group was lower than that of the NT-V group ($0.18{\pm}0.10\;unit/ml$ vs $0.43{\pm}0.22\;unit/ml$;p=0.046). Conclusions : Hypothermia attenuated pulmonary hemorrhage, permeability pulmonary edema, and alveolar cellular injuries associated with injurious mechanical ventilation, and preserved normal P-V characteristics of the lung in rats.

Purpose: Bleeding is the primary cause of death after severe pelvic fracture. Transcatheter arterial embolization (TAE) is the mainstay of treatment for arterial bleeding. This study aimed to determine the frequency of bleeding by angiography of blush-positive pelvic fractures on computed tomography (CT) images. The bleeding arteries that were involved were investigated by pelvic angiography. Methods: This retrospective cohort study evaluated 83 pelvic fracture patients who were treated in the intensive care unit of the author's trauma center between January 01, 2013 and April 30, 2015. Results: Overall mortality was 9 of 83 patients (10.8%). Blush was observed in 37 patients; blush-positive patients had significantly higher mortality (24.3%) than blush-negative patients (0%). Twenty-four of the 83 patients (28.9%) underwent pelvic angiography. Bleeding was showed in 22 of 24 patients in pelvic angiography. TAE was successfully performed in 21 (95.5%) of the bleeding 22 patients. Angiography was performed in 23 of 37 blush-positive patients, and arterial bleeding was identified in 21 (91.3%). A total 33 bleeding arteries were identified in 22 angiography-positive patients. The most frequent origin of bleeding was internal iliac artery (69.7%) followed by the external iliac artery (18.2%) and lumbar arteries (12.1%). Conclusion: The vascular blush observed in CT scans indicates sites of ongoing bleeding in pelvic angiography. TAE is an excellent therapeutic option for arterial bleeding and has a high success rate with few complications.
