Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

The resistance of a structure against an earthquake is related to its ability to absorb the seismic input energy. The development of devices for dissipating the seismically induced energy on the structure is a subject that is receiving large attention in the field of earthquake engineering. One example of these devices is the steel plate with slits. In this paper, a connection with a slit-type steel plate damper installed at each ends of wide-flange section beam, as an energy absorption element, was proposed. A series of experiment was performed to investigate their behavior and structural characteristic. The main parameters were the aspect ratio of the struts in slit plates, thickness of the struts and height of the vertical places. Test results indicated that most of the energy was absorbed by plastic deformation of slit plate dampers.

연구배경:췌도세포 이식은 시술이 간편하고 안전하기 때문에 반복이식이 가능하여 그 동안 여러 센터에서 반복이식의 성공을 보고한 바 있다. 국내에서도 본 병원을 비롯하여 몇몇 센터에서 췌도세포 이식이 활발히 시도되고 있으나 사람에서의 동종이식 및 동종 이식의 반복시행은 보고된 바 없는 실정이다. 저자 등은 국내 최초로 췌도세포 동종이식을 시행하여, 혈청 C­펩타이드가 증가하고 인슐린 요구량이 감소하였으며, 혈당농도와 당화혈색소의 안정을 보였다. 그러나 이식 70일 후 다시 인슐린 요구량이 증가하고 C­펩타이드가 감소하여 췌도세포 이식을 다시 시행한 바 있다. 2차 이식 후 70여일이 지난 현재 다시 혈청 C­펩타이드가 증가하고, 인슐린 요구량이 더 감소되어 췌도세포 이식에서 반복 시행의 유용성을 보고하는 바이다. 방법:환자는 32세 남자로 17년전 당뇨병 진단 후 인슐린 치료 중이었으며, 3년전 부터는 만성신부전증으로 혈액툭석을 하고있었다. 1999년 12월 25일 신장이식을 하였고 3일 후 췌도이식을 하였으며, 두번째 이식은 70일 후 시행하였다. 췌도분리는 변형된 Recordi방법과 비연속성 자당 농도차(discontinuous density gradient)를 이용하였으며 분리한 췌도는 배양 후 환자의 신장기능이 정상화되고 미생물학 검사에서 음성을 확인한 후 경피경간으로 간문맥을 접근하여 16G 폴리 에틸렌 카테터를 이용하여 간실질에 이식하였다. 결과:1차 췌도이식시 순수분리전 췌도수는 210,000개, 순수분리후 획득한 췌도수는 90,000개, 순도 95%, 세포양 1.0mL 이었고, 2차 췌도이식시 순수분리전 췌도수는 420,000개, 순수분리후 획득한 췌도수는 370,000개, 순도 95%, 세포양 1.5mL 이었다. 1,2차 모두 간문맥을 통해 약 20분에 걸쳐 간실질에 주입하였다. 췌도이식전 인슐린요구량은 75∼75U/일, HbA1e 8∼10%, C­펩타이드 0.6ng/mL 였으며, 1차 췌도이식수 7일째 인슐린 요구량은 40U/일, C­펩타이드 1.5ng/mL, FPS 109mg/mL 였고, 40일 추적관찰 후 인슐린 요구량이 36U/일, C­펩타이드 1.8ng/mL, HbA1e 6.5∼7.0%로 안정되었다. 그러나 이식 50일째부터 인슐린 요구량이 50∼56U/일, C­펩타이드 0.6ng/mL, FPS 130∼200mg/dL로 혈당 조절이 불안정하여 다시 췌도이식을 시행하였다. 2차 이식후 50일이 경과한 현재, 인슐린 요구량은 26U/일, C­펩타이드 1.8ng/mL, FPS 90∼120mg/dL로 다시 안정되었다. 결론:췌도이식은 반복이식이 가능하며, 본 환자의 경우 인슐린요구량 감소, 혈당의 안정화 및 C­펩타이드가 상승하여 이식한 췌도의 기능을 확인할 수 있었고, 향후 스테로이드 등 면역억제가 유지 용량으로 감량되면 인슐린 요구량은 더 감소될 것으로 기대된다. Over the past 20 years, significant advances have been made in human islet transplantation. However, cases of prolonged insulin independence after islet allotransplantation have rarely been reported and over time, a slight, gradual decrease in insulin secretion appears to occur, as suggested by the lower C-peptide. Although preliminary clinical success achieved over the past few years has been considerably higher with whole pancreatic transplant than with isolated islet grafts, both approaches remain experimental. Islet grafts might gain, over time, increasing credibility and might eventually provide an easier alternative in terms of grafting procedures and patient management, as compared with the more "traumatizing" whole-pancreas transplantation. Also, using islet, re-transplantation is possible. But it is not known whether re-transplantation of islet could be suitable for those patients who lost grafted islet function. The aim of the present study was to investigate the benefits of re-transplantation of islet in previously simultaneous islets-kidney transplant (SIK) patient who have lost graft function. Methods : The recipient was a 32 year old male. First islet transplantation was underwent at December 25, 1999. However, the grafted islets lost function after 70 days. So we performed re-transplantation of islets. The isolation of islet was conducted sterilely on a laminarflow hood and isolated by a modified Recordimethod. The islet was injected slowly into the liver via a cannular placed in the potalvein for 20 minutes. Results : Transplanted islets were 90,000 IEq at first islet transplantation, 370,000 IEq at second islet transplantation. The insulin requirement was reduced from 75-85 to 35-40 U/day, the basal C-peptide level was 1.5 ng/mL at 7 days posttransplant Unfortunately, the grafted islets lost function after 70 days. After second transplantation, the insulin requirement was reduced to 26 U/day. Conclusions : Despite the continuous need for exogenous insulin therapy, islet transplantation can prevent wide glucose fluctuations, thus resulting in normalization of glycemic control and improvement in HbAlc, and also, show that islets can be successfully and safely re-transplanted intraportally in patients who have lost previously grafted islet function (J Kor Diabetes Asso 457~466, 2000).
