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.

Objective This study aimed to introduce a method to remove huge ovarian tumors (≥15 cm) intact with single-port laparoscopic surgery (SPLS) using SW Kim`s technique and to compare the surgical outcomes with those of laparotomy. Methods Medical records were retrospectively reviewed for patients who underwent either SPLS (n=21) with SW Kim`s technique using a specially designed 30×30-cm2-sized 3XL LapBag or laparotomy (n=22) for a huge ovarian tumor from December 2008 to May 2016. Perioperative surgical outcomes were compared. Results In 19/21 (90.5%) patients, SPLS was successfully performed without any tumor spillage or conversion to multi-port laparoscopy or laparotomy. There was no significant difference in patient characteristics, including tumor diameter and total operation time, between both groups. The postoperative hospital stay was significantly shorter for the SPLS group than for the laparotomy group (median, 2 [1 to 5] vs. 4 [3 to 17] days; P<0.001). The number of postoperative general diet build-up days was also significantly shorter for the SPLS group (median, 1 [1 to 4] vs. 3 [2 to 16] days; P<0.001). Immediate post-operative pain score was lower in the SPLS group (median, 2.0 [0 to 8] vs. 4.0 [0 to 8]; P=0.045). Patient-controlled anesthesia was used less in the SPLS group (61.9% vs. 100%). Conclusion SPLS was successful in removing most large ovarian tumors without rupture and showed quicker recovery and less immediate post-operative pain in comparison to laparotomy. SPLS using SW Kim`s technique could be a feasible solution to removing huge ovarian tumors.

Jehovah's Witness comprise a unique obstetric population. Their refusal of blood stems from an interpretation of a literal translation of the Bible, and it is this belief that puts them at an increased risk of morbidity and mortality if hemorrhage occurs. We report two cases of a Jehovah's Witness who bled massively due to obstetric hemorrhage, refused blood transfusion and had profound anemia. The patients were treated with recombinant human erythropoietin, parenteral iron and oxygen. And they were treated on an intensive care unit with intermittent positive pressure ventilation. We reviewed with literature considering the therapy for acutely anemic patients who refuse transfusion to decrease the duration of the most severe anemia.

새로운 ATM 서비스인 ABR은 최근에 발생된 서비스 클래스이다. ATM 망에서 속도기반 흐름제어 방식은 목적지 또는 망 스위칭 노드에서 발생하는 RM셀들에 포함된 궤한정보를 기반으로하여 ABR트래픽 소스들의 전송속도를 제어하는 것이다. 결국 사용자에게 유용한 대역폭을 할당하는 것이다. ATM 망이 다른 속도제어 방식 즉, EFCI 모드와 ER방식을 사용하는 스위치로 구성되었을 때, 망성능과 대역폭 할당의 공정성에 관하여 연구하였다 ABR, new ATM service, is service class that currently was originated. The rate-based flow control mechanism in Asynchronous Transfer Mode(ATM) networks controls the transmission rate of Available Bit Rate(ABR) traffic sources, based on feedback information contained in the Resource Management(RM) cells coming from the destination and the network switching nodes. Finally by controlling traffic flow, available bandwidth to users is allocated. This paper investigates network performance and fairness of bandwidth allocarion When an ATM network consists of switches using different rate control mechanims, namely, the Explicit Forward Congestion Indication(EFCI) mode and the Explicit Rate(ER) mechanism

Meso-dihydroguaiaretic acid (MDGA) is a medicinal herbal product isolated from the aerial parts of Saururus chinensis that inhibits the cyclooxygenase-2 (COX-2)-dependent phase of prostaglandin D2 (PGD2) generation in bone marrow-derived mast cells (BMMC) (IC50 9.8 μM). However, this compound did not inhibit COX-2 protein expression in BMMC at concentrations up to 30 μM, indicating that MDGA directly inhibits COX-2 activity. In addition, this compound consistently inhibited the production of leukotriene C4 (IC50 1.3 μM). These results demonstrate that MDGA inhibits both COX-2 and 5-lipoxygenase. Furthermore, this compound strongly inhibited the degranulation reaction in BMMC (IC50 11.4 μM). Therefore, this compound might provide a basis for novel anti-inflammatory drug development.

연구배경: 비혈연간 조혈모세포이식은 HLA체계에 대한 이해의 증진과 새로운 검사법의 개발, 그리고 기증자 수의 증가에 힘입어 최근 빠르게 증가하고 있다. 방법: 가톨릭조혈모세포이식센터에서 1995년 10월부터 2001년 12월까지 비혈연간 이식을 받은 138명의 성인 환자를 대상으로 후향적 분석을 하였다. 결과: 질환별로 만성골수성백혈병 66예, 급성림프구성백혈병 23예, 급성골수성백혈병 16예, 재생불량성빈혈 21예, 골수이형성증후군 9예, 비호지킨림프종 2예, 그리고 발작성야간혈색소뇨증이 1예였다. 일차 생차부전은 분석가능한 136예 중 4예(2.9%)에서 발생하였다. Ⅱ도 이상의 급성이식편대숙주병의 발생률은 48.1%였고, 만성이식편대숙주병은 49.5%였다. 재발 이외의 사망원인 중 가장 높은 빈도를 보인 것은 폐렴으로, 독성사망 64예 중 36예(52.3%)에서 관찰 되었다. 만성골수성백혈병의 경우(n=66), 무병생존율, 재발률, 비재발성 사망률이 각각 45.7%, 11.4%, 49.2%였다. 무병생존율은 표준위험군이 고위험군에 비해 통계적으로 유의하게 높았다(50.3% vs 32.0%, p=0.03). 급성림프구성백혈병의 경우(n=23), 무병생존율, 재발률, 비재발성 사망률이 각각 30.0%와 49.4%, 44.8%였던 반면, 급성골수성백혈병에서는(n=16) 28.6%, 39.4%, 52.9%였다. 이들 급성백혈병에서는 표준위험군에 비해 고위험군에서 재발률과 비재발성 사망이 모두 높게 관찰되었다. 중증재생불량성빈혈의 경우(n=21), 무병생존율과 비재발성 사망이 37.3%와 62.7%였다. 결론: 본 연구의 결과 비혈연간 이식은 HLA적합 형제가 없는 혈액질환 환자들에게 유용한 치료법의 하나임을 알 수 있었다. 낮은 병기에서의 조기 이식과 분자생물학적 방법을 사용한 HLA 적합도의 개선이 이식관련 사망을 최소화시켜 비혈연간 이식의 효과를 더욱 확대시킬 수 있을 것으로 생각된다. Background: Unrelated allogeneic stem cell transplantation (U-SCT) is recently on a increasing trend supported by better understanding of HLA system, development of new HLA typing, and increase of donor pool. Methods: We retrospectively analyzed 138 adult patients who underwent U-SCT between October 1995 and December 2001 at Catholic Hematopoietic Stem Cell Transplantation Center. Results: Diagnoses were chronic myeloid leukemia (CML, n=66), acute lymphoblastic leukemia (ALL, n=23), acute myeloid leukemia (AML, n=16), severe aplastic anemia (SAA, n=21), myelodysplastic syndrome (MDS, n=9), non-Hodgkin lymphoma (NHL, n=2), and paroxysmal nocturnal hemoglobinuria (PNH, n=1). Primary engraftment failure was observed in 4 (2.9%) of 136 evaluable patients. Acute GVHD (≥grade II) occurred in 48.1% and chronic GVHD occurred in 49.5%. The most common cause of death other than relapse was pneumonia, which occurred 36 (52.3%) of 64 toxic deaths. In CML, disease-free survival (DFS), relapse rate, and non-relapse mortality (NRM) was 45.7%, 11.4%, and 49.2%. DFS of the standard-risk group (SR) was significantly better than that of high- risk group (HR) (50.3% vs 32.0%, P=0.03). In ALL, DFS, relapse rate, and NRM was 30.0%, 49.4%, and 44.8%, whereas corresponding figures for AML were 28.6%, 39.4%, and 52.9%. NRM and relapse rate were higher in HR compared to SR in acute leukemia. In SAA, DFS and NRM was 37.3% and 62.7%. Conclusion: We concluded that U-SCT is a feasible therapeutic option for patients lacking a HLA-matched sibling donor. Transplantation at earlier phase of disease with more accurate HLA matching by molecular typing can minimize treatment-related toxicity and could extend the benefit of U-SCT.

Periosteal osteosarcoma is a distinct entity of malignant bone tumor with characteristic clinical, morphological, and histological features within the group of juxtacortical osteosarcoma. Periosteal osteosarcoma is predominantly located in the tubular long bones, and extremely rarely involving the jaws. A case of periosteal osteosarcoma of the right mandible is presented. A 27-year-old woman complained of the gingival swelling and bleeding tendency of the right posterior mandible. Clinical examination revealed a reddish brown strawberry-like swelling on the affected mucosa, which measured 1.5㎝×1.5㎝. The tumor was located on the lingual cortex of the mandible and extended into the surrounding soft tissues. Microscopically, the tumor consisted exclusively of atypical chondroblastic cells with a small osteoblastic area. A minimal bone marrow involvement was noted and the adjacent cortex was free of tumor. These findings suggested that the tumor originated from the periosteal cambium layer, which lies between the periosteal fibrous layer and the cortex of mandible.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.
