Purpose: The gastrointestinal (GI) tract is the most common site of extranodal non-Hodgkin's lymphoma (NHL), which is increasing in incidence, but there is no established optimal treatment modality. Thus, this study was investigated the clinicohistologic feature, the therapeutic modalities, and the prognosis for GI-NHL, as well as the factors affecting it. Methods: We retrospectively analyzed 45 patients who had been diagnosed as having GI-NHL and had been followed up from July 1994 to February 2005 at Soonchunhyang University Hospital. The patients were divided into groups according to the site of origin and to various other features, and the survivals of the various groups were compared. The modified Ann Arbor system and WHO classification were adopted for staging and histopathologic classification, respectively. Results: GI-NHL of the stomach, small bowel, ileocecal region, and colon occurred in 28 patients (62.2%), 5 patients (11.1%), 3 patients (6.7%), and 8 patients (17.8%), respectively, In one patient, the entire gastrointestinal tract was diffusely involved. The median age of patients was b5 years (25~78 years), and male-to-female ratio was 1:1.1. Fourteen patients were in stage Ⅰ, 24 in stage Ⅱ, 4 in stage Ⅲ, and 3 in stage Ⅳ. Surgical resection was performed in 19 patients, and combination chemotherapy was performed in 43 patients. Surgical resection only was performed in 4 patients, Chemotherapy only was performed in 26 patients. The expected overall 5 year survival of 45 patients was 39.6%, and there was a significant survival difference between the stages, but between sites of origin (p=0.842). The most important factors influencing the survival was the stage and other factors were not significant. Conclusion: The stomach was the most common site of GI-NHL. Most GI-NHL were localized Stage was the most important prognostic factor. However, Prospective randomized studies are needed to approve the therapeutic modality.

Background and Objectives: Immunolabelling of interstitial Cajal(IC) cells in the intestinal wall has recently been developed by using a specific marker, the anti-c-Kit antibody. Substance-P is a well-known neurotransmitter in the gastro-intestinal tract. Since the gastro-intestinal wall structures have already been well documented in the guinea pig, immunohistochemistry was done for the c-Kit-positive IC network and substance-P receptor(NK1R) in an attempt to provide a morphological basis for the mechanism regulating gastro-intestinal movement. Materials and Methods: Cryosection and whole-mount preparations of guinea pig small intestine and colon were single and double immunolabelled using the anti-c-Kit and NK1R antibodies. Immunolabelled specimens were observed under a confocal laser scanning microscope. Results : According to a three dimensional reconstruction study, it was found that (1) the c-Kit-positive celluar networks were widely distributed in the intestinal wall, (2) c-Kit-positive celluar networks encircled the ganlion, with strands in reticular configurations, and (3) the c-Kit-positive cells showed colocalization with NK1R in circular muscle(CM), not myenteric plexus(MY). Conclusion: The charateristic profiles of IC containing c-Kit-positive celluar networks and the relationship between c-Kit-positive and NK1R-positive structures provide a morphological basis upon the mechanism regulating gastro-intestinal motility.

<P>Mesenchymal stem cells (MSCs) have recently been identified and characterized in humans. Moreover, MSC secrete cytokines that can support hematopoietic progenitor growth. In the present study, we evaluated whether the efficacy of hematopoietic stem cell transplantation is improved by their co-transplantation with MSC, and whether this is positively correlated with the dose of infused MSCs. Accordingly, irradiated NOD/SCID mice were transplanted with 1×10<SUP>5</SUP> human CD34+ cells in the presence or absence of culture expanded MSCs (1×10<SUP>6</SUP> or 5×10<SUP>6</SUP>). We evaluated human hematopoietic cell engraftment by flow cytometry and assessed MSC tissue distributions by fluorescence in situ hybridization. We found that CD45+ and CD34+ cell levels were significantly elevated in a dose-dependent manner in cotransplanted mice 4 weeks after transplantation. The engraftments of CD33+ and CD19+ cells also increased dose-dependently. However, the engraftment of CD3+ cells did not increase after co-transplantation with MSCs. Human Y chromosome+ cells were observed in multiple tissues and were more frequently observed in mice co-transplanted with 5×10<SUP>6</SUP> rather than 1×10<SUP>6</SUP> MSCs. These results suggest that MSCs are capable of enhancing hematopoietic cell engraftment and distribution in multiple organs in a dose-dependent fashion.</P>

<P>cDNA microarray-based CGH (Microarray-CGH) is a useful technique for detecting genomic aberrations with a high resolution. However, the criteria for determining a genomic alteration have not been determined. We evaluated the genome-wide measurement of copy number of each gene in normal gastric and placenta tissues with both sex-matched, direct and sex-mismatched, indirect designs using 17K cDNA microarray. The results revealed the range of genomic copy number of normal tissues to be +/-0.3 of the log(2) ratio (gain >0.3, loss <-0.3) in the autosomal genes with direct and indirect designs. The copy number at a gene level from the X chromosomal genes using the direct and indirect sex-mismatched designs was +/-0.68 of the log(2) ratio (amplification >0.68, deletion <-0.68). In summary, the suggested method can be used as a guideline for analysis of genomic aberration using a Microarray-CGH in both direct and indirect designs.</P>

조혈모세포이식을 받은 환자에서 만성 이식편대 숙주질환의 증상으로 발생할 수 있는 다발성근염과 담즙성 간경변은 각각 드물게 보고되나 다발성근염과 담즙성간경변이 동시에 발생한 경우는 극히 드물다. 이에 저자들은 동종조혈모세포이식 14개월 후 상하지 근무력감과 전신쇠약감을 주소로 내원한 환자에서 근전도, 근조직검사, 항미토콘드리아 항체, 간 조직검사를 통하여 다발성 근염과 이차성 담즙성 간경변이 동시에 발생한 경우를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Polymyositis and biliary cirrhosis have been described as a rare complications in patients who develop chronic graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (HSCT). The concomittant occurrence of polymyositis and biliary cirrhosis developing after allogeneic HSCT might be extremely rare. Fourteen months after HSCT, a 25-year-old man developed polymyositis with biliary cirrhosis as manifestations of chronic GVHD. Polymyositis was diagnosed by the serum muscle enzymes, electromyographic, and histopathologic findings, and biliary cirrhosis was confirmed by the antimitochondrial antibody and histopathologic findings. His clinical condition was improved with cyclosporin and low dose prednisolone therapy. We report herein a case of polymyositis and secondary biliary cirrhosis that occurred concomittantly after allogeneic HSCT.

목적: 치료에 반응하지 않는 불응성 암성 통증이 척수의 substantia gelatinosa 부위에 있는 NMDA 수용체와 관련이 있다고 알려져 있다. NMDA 길항제의 역할을 하는 ketamine은 마취용량 이하 수준에서 이런 불응성 암성 통증에 산발적으로 사용하여 진통효과를 보았다는 연구보고가 있었다. 보존적인 치료 측면에서 ketamine은 주로 피하주사를 통한 투여방법이 사용되며, 마약성 진통제와 한 두개 이상의 보조진통제들과 함께 보조요법으로 사용된다. 현재까지 ketamine과 연관되어 진행된 연구 대부분이 신경병증성 통증을 대상으로 증례보고 형태이거나 소규모의 연구이었다. 따라서 불응성 암성 통증 환자에 있어 ketamine의 효과가 일관되게 확인되지 않았으므로 이에 대한 검증이 필요하며, ketamine 사용에 따라 발생할 수 있는 부작용이나 환자의 영향에 대한 분석이 필요하다. 방법: 2001년 3월부터 2004년 11월까지 순천향대학교부천병원에서 불응성 암성 통증으로 치료를 받았던 58명의 환자를 대상으로 3일 동안 ketamine을 초기 용량 100 mg/일로부터 단계적으로 점차 증량하였으며, 통증이 지속되고 중대한 부작용이 발생하지 않은 한 300 mg/일까지 증량하였다. 진통효과는 숫자통증등급을 사용하여 매 6시간 간격으로 측정하였으며, 진통효과가 있다고 판정하는 기준은 ketamine 투여 전·후에 통증 score가 50% 이상 감소하는 경우로 하였다. 또한, 마약성 진통제 요구량의 감소 정도와 약제투여에 따른 부작용도 평가하였다. 결과: Ketamine 사용 중에 치료가 중단된 예는 없었으며, ketamine 투여 후 진통효과는 50% 이상 감소한 경우가 20명(34.5%), 50% 미만의 효과가 있었던 경우가 24명(41.4%), 효과가 없었던 경우가 11명(19%), 오히려 통증이 악화된 경우가 3명(5.2%)이었다. Ketamine 투여 후 진통제의 요구량이 감소한 경우는 24명이었다. 또한, ketamine 투여에 따른 주요 부작용은 구역, 구토, 혼동, 졸림 등의 부작용이 발생하였으나, 일시적이거나 증상치료 후 곧 호전되는 정도로 경·중증도의 부작용이었다. 결론: 말기 암 환자에 있어 ketamine의 사용은 삶의 질 저하에 가장 큰 요인인 암성 통증을 완화시킬 수 있으며, 더불어 마약성 진통제의 요구량을 경감시킬 수 있는 보조요법으로 역할을 할 수 있으리라 기대한다. Background: There has been growing evidence of the importance of the N-methyl-D- aspartate (NMDA) receptor in intractable pain. There is good evidence from experimental animal models and clinical trials that ketamine as a NMDA receptor antagonist relieves neuropathic pain. We evaluated whether ketamine in low doses as an adjuvant to opioid treatment improves analgesia with tolerable adverse effects. Methods: 58 patients with intractable cancer pain received ketamine for 3 days. Each pain type was classified as a somatic, visceral, or neuropathic pain. We assessed pain at 6 hourly intervals with vital signs using a numeric rating scale. Data on opioid doses, ketamine dose, and adverse effects were recorded daily on an assessment chart. To be designated as a responder, a patient had to show a 50% or greater reduction in the mean pain scale. Results: The overall response rate was 34.5%. The results according to the type of pain mechanism showed that 47% (15/32) patients with neuropathic and 25% (5/20) patients with somatic pain responded. In 24 cases (41.4%), the requirement for an opioid dose was reduced after infusion of ketamine. The most common adverse effects were nausea and vomiting. Eleven patients complained of drowsiness or transient hallucination. However, most adverse effects were mild to moderate and were easily relieved by treatment. Conclusions: This study demonstrates that the infusion of ketamine in low doses may have an effect on intractable cancer pain and in reducing opioid requirements, especially neuropathic pain with acceptable toxicities. Therefore, ketamine may be useful as an adjuvant to opioid treatment in cancer patients who are receiving palliative care. (Korean J Med 72:298-305, 2007)

We fabricated Bi-2212/ composite superconductors and evaluated the effects of the powder mixing method and melting temperature on their microstructure and superconducting properties. The Bi-2212 powders were mixed with by hand-mixing (HM) and planetary ball milling (PBM) and then the powder mixtures were melted at , solidified, and annealed. We found that the powder mixture prepared by PBM was finer and more homogeneously mixed than that prepared by HM, resulting in more homogeneous microstructure and smaller and second phases after annealing.
