This study was conducted to investigate the effects of the marketing strategy based on the traditional wrestling, which affects the tour industry. The study used the simple random sampling method in the group of the Kwang-Ju district citizens. The group representatives were directly interviewed, and 277 interviewees replied with concern. The rest of the interviewees were not interested in the survey. The general characteristics of the interviewees -- gender, age, education, job, monthly salary. -- were used to analyze the items related to Sports Tourism in general. Sport Tourism in general Male interviewees had higher recognition over females in the interview. The rate of experience was low for both genders. According to their education, the satisfaction of sport tourism showed low rate. However, there were many answers where the interviewees, not depending on the age or gender, indicated that they will participate in the future. The policy recommended based upon the results of the study is as follows. There is a need for setting up a new strategy in order to increase participation of sports. Also, it is urgent to set up a sports theme center to raise professional sportsmen and to supply them to where they are needed.

This study was the marketing strategy based on sports tourism, which affects the tour industry. The study used the simple random sampling method in the group of the Kwang-Ju district citizens. The group representatives were directly interviewed, and 277 interviewees replied with concern. The rest of the interviewees were not interested in the survey. The general characteristics of the interviewees -- gender, age, education, job, monthly salary. --were used to analyze the items related to the marketing strategy for the traditional wrestling. In the product selling strategy, there was a significant difference depending on the job and age difference. The interest put on the game changed according to the age difference. The suggested policy is as follows. There is a need for a certain space, in order to provide the public relations of the date and location of the sports tourism match, which will be the product selling strategy. Also, the promotion strategy, using various events, is required urgently. Moreover, it would be good to have more than just viewers of family and friends, but to develop more active programs with higher participation level. This study is, valuable, in the sense that it offers fundamental information related to the traditional wrestling and its marketing strategy, when there is no such information in this field. It is expected for the readers to utilize this study to investigate more into the field, or to look up for new plans to activate the sports tourism.

Five adults (3 cases of bilateral posterior crossbite, 2 cases of unilateral posterior crossbite) with intermaxillary discrepancy of over 5㎜ due to maxillary transverse deficiency were treated by surgically assisted rapid maxillary expansion (SARME). Bilateral maxillary horizontal osteotomies, osteotomies of pterygomaxillary junction and anterior lateral nasal wall, ans anterior palatal osteotomy were performed in 4 cases, and unilateral osteotomies in 1case, followed by palatal expansion with tooth-borne orthopedic applicance. No significant complication was observed. The mean palatal expansion was 7.2㎜ (5.8∼10.0㎜) in the maxillary first molar region. During the mean follow-up period of 4 years (5 months∼8 years 7 months), no recurrence of crossbite was observed in all cases. The SARME seemed to be a simple, stable, and reliable procedure for achieving a permanent increase of over 5㎜ in skeletal maxillary transverse width of adults.
ELISA에 의한 뇌척수액내 Fibronectin의 측정과 임상적 의의

신경계 질환의 진단은 임상 소견과 뇌척수액 검사소견 등을 기초로 하고 있다. 그러나 이들 소견이 각 질환간의 감별에 분명한 도움을 주고 있지는 못하고 있다. 이에 본 연구에서는 뇌척수액 fibronectin을 측정하여 여러 신경계 질환과의 관련을 조사하고 나아가 이들 질환의 감별에 도움을 얻고자 하였다. Fibronectin은 뇌척수액내 미량으로 존재하므로 이의 측정을 위하여 먼저 측정능이 좋은 ELISA를 개발하였다. 그 결과 농도가 10 ng/ml에서부터 100 ng/ml의 범위내에서 뇌척수액 fibronectin 농도를 측정할 수 있었다. 결핵성 뇌막염 9례, 바이러스성 뇌막염 5례, 세균성 뇌막염 2례를 포함한 기타 신경계 질환 8례 및 정상대조군 18례 등 총 40례를 대상으로 뇌척수액내 fibronectin농도를 조사한 결과, 결핵성 뇌막염군은 4.21±2.32 ㎍/㎖, 바이러스성 뇌막염군은 0.9±0.79 ㎍/㎖, 기타 질환군은 2.05±2.48 ㎍/㎖, 그리고 정상대조군은 1.35±0.84 ㎍/㎖의 평균값을 보여 결핵성 뇌막염군이 기타 질환군을 제외한 타 질환군들에 비해 통계적으로 유의하게 높은 값을 보였다(p<0.01). 결핵성 뇌막염의 경우 1례를 제외하고는 모두 2.9 ㎍/㎖ 이상이었고, 3례(38%)에서는 4.6 ㎍/㎖ 이상이었던 반면, 바이러스성 혹은 무균성 뇌막염에서는 1례에서만 2.2 ㎍/㎖이고 나머지는 모두 1 ㎍/㎖ 이하로 나타났다. 이상의 결과로 보아 뇌척수액내 fibronectin농도의 측정은 결핵성 뇌막염과 바이러스성 뇌막염의 감별진단에 유용하리라 생각된다. The diagnosis of neurologic diseases is based on the clinical symptoms and cerebrospinal fluid findings. These findings, however, are often ambiguous. This study aims to evaluate the diagnostic value of cerebrospinal concentration of fibronectin. Fibronectin level in cerebrospinal fuid was measured by ELISA which could detect fibronectin in the range from 10 ng/ml to 100 ng/ml. Nine cases of tuberculous menigitis, 5 cases of viral meningitis, 8 cases of miscellaneous neurologic conditions and 18 cases of normal controls were studied. The mean value of fibronectin level in cerebrospinal fluid in tuberculous meningitis was 4.21±2.32 ㎍/㎖, in viral meningitis 0.9±0.79 ㎍/㎖, in miscellaneous neurologic conditions 2.05±2.48 ㎍/㎖ and in controls 1.35±0.84 ㎍/㎖. The fibronectin level in tuberculous meningitis was significantly higher than in other groups except the miscellaneous neurologic conditon(p<0.01). Cerebrospinal fluid fibronectin level appeared to be useful to differentiate tuberculous meningitis fro viral meningitis. Those levels were higher than 2.9 ㎍/㎖ in all except one case and higher than 4.6 ㎍/㎖ in 38% of tuberculous meningitis cases, but, 2.2 ㎍/㎖ in only one case of viral meningitis and lower than 1.0 ㎍/㎖ in all except one case of viral meningitis. It is suggested that measurement of fibronectin level in cerebrospinal fluid is a useful test for diagnosis of tuberculous meningitis, especially for differential diagnosis between tuberculous and viral meningitis.

페그인터페론과 리바비린 병합요법은 만성 C형 간염의 일차 치료법이다. 저자들은 만성 C형 간염 환자에서 페그인터페론 과 리바비린 병합 요법 중에 발생한 벨마비 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 5년 전부터 만성 C형 간염을 앓아온 48세 남자이며, PEG-IFN α-2a 135μgm 피하주사 주1회와 하루 1200㎎의 리바비린을 투여하였다. 치료시작 후 9개월째 환자는 오른쪽 안면의 근력약화를 호소하였으며 벨마비로 진단되었다. 페그인터페론과 리바비린 병합요법을 지속하면서 관찰하였다. 환자의 벨마비는 페그인터페론 치료를 중단하지 않았음에도 3개월후 증상이 회복되고 이후 벨마비 재발 없이 현재 경과관찰 중이다. 만성 C형 간염에서 페그인터페론과 리바비린 병합 요법시 벨마비의 발생 가능성을 염두에 두어야 하겠다. A Case of Bell's Palsy Associated with Combination Therapy of Pegylated Interferon Alfa-2a (PEG-IFN) and Ribavirin for Chronic Hepatitis C Virus Infection Pegylated interferon alfa(PEG-IFN α) and ribavirin therapy is the first line treatment for chronic hepatitis C. Mild complications of the therapy are common, but more serious complications are rare. We report here a case of Bell's palsy that occurred in a patient with chronic hepatitis C virus infection during combination therapy of PEG-IFN α-2a and ribavirin. The patient was 49-year-old man with chronic hepatitis C (genotype 1b) for 8 years. He had compensated liver cirrhosis with splenomegaly. Therapy with PEG-IFN α- 2a 135mcg/week and ribavirin 1200mg/day was initiated. After 9 months of the therapy, the patient showed a loss of muscular tone on the right side of his face. A diagnosis of Bell's palsy was made. The Bell's palsy resolved over 3 months despite continuation of the combination therapy.
뇌하수체 종양 제거술 시행 후 뒤늦게 발생한 횡문근 융해증과 동반된 중추성 열

Body temperature is controlled by thermoregulatory center of the hypothalamus. We report a case of 24 years old man with central fever. He was subjected to a partial excision of pituitary tumor compressing optic chiasm four years ago. He has received hormonal therapy for panhypothyroidism after removal of pituitary tumor. And He received gamma knife operation for partially contrast-enhancing masses in suprasellar and both hypothalamic areas that is probably postoperatively remnant or recurrent tumor of pituitary adenoma. One year after gamma knife operation, he presented with a febrile syndrome of unknown origin including rhabdomyolysis. All usual investigations proved negative. We diagnosed him as central fever with rhabdomyolysis. He received medical ICU care with cooling bed, ice pack. And his symptom improved. Postoperative hyperthermia may result following resection of the pituitary tumor. When central fever is suspected taking note of past history, a quick recognition of course of fever can help reduce the using of unnecessary antibiotics and hospital stay.

Over-expression of nicotinamide adenine dinucleotide phosphate oxidase (Nox) isoform enzymes was recently reported in various cancers including Burkitt’s lymphoma (BL). However, the functions of Nox isoform enzymes in BL remain poorly understood. In this study, Nox isoform expression and the effects of a Nox-specific inhibitor were evaluated in Epstein-Barr virus (EBV)-positive Raji BL cells in comparison with EBV-negative Ramos BL cells. To evaluate Nox enzyme expression in Raji and Ramos BL cells, polymerase chain reaction (PCR) and western blot analysis were performed. To verify the intracellular signaling mechanism of the Nox inhibitor-induced apoptosis of Raji cells, WST-1 assay, trypan blue exclusion method, flow cytometry, PCR, western blotting, and bromodeoxyuridine staining were conducted. Experiments using the pan-caspase inhibitor z-VAD, reactive oxygen species scavenger N-acetyl-L-cysteine (NAC), and Bim inhibitor 1 were performed. PCR and western blot results showed that Nox isoform enzymes were highly expressed in EBV-positive BL Raji cells compared with EBV-negative BL Ramos cells. The Nox2 inhibitor induced apoptosis of Raji cells in time- and dose-dependent manners. The Nox2 inhibitor also caused up-regulation of Bim and Noxa, down-regulation of Mcl-1, translocation of Bax, release of cytochrome c, and caspase cascade activation, resulting in apoptosis. Furthermore, z-VAD, NAC, and BI-1 effectively blocked the Nox2 inhibitor-induced apoptosis of Raji cells. Taken together, these results provide a novel insight into the mechanism of Nox inhibitor-induced apoptosis and evidence for Nox as a therapeutic target to treat EBV-positive malignancies.
Review : Biliary Strictures after Liver Transplantation
( Choong Heon Ryu ),( Sung Koo Lee ) 대한소화기기능성질환·운동학회(구 대한소화관운동학회) 2011 Gut and Liver Vol.5 No.2
Biliary strictures are one of the most common complications following liver transplantation, representing an important cause of morbidity and mortality in transplant recipients. The reported incidence of biliary stricture is 5% to 15% following deceased donor liver transplantations and 28% to 32% following living donor liver transplantations. Bile duct strictures following liver transplantation are easily and conveniently classifi ed as anastomotic strictures (AS) or non-anastomotic strictures (NAS). NAS are characterized by a far less favorable response to endoscopic management, higher recurrence rates, graft loss and the need for retransplantation. Current endoscopic strategies to correct biliary strictures following liver transplantation include repeated balloon dilatations and the placement of multiple side-by-side plastic stents. Endoscopic balloon dilatation with stent placement is successful in the majority of AS patients. In patients for whom gaining biliary access is technically diffi cult, a combined endoscopic and percutaneous/surgical approach proves quite useful. Future directions, including novel endoscopic retrograde cholangiopancreatography techniques, advanced endoscopy, and improved stents could allow for a decreased number of interventions, increased intervals before retreatment, and decreased reliance on percutaneous and surgical modalities. The aim of this review is to detail the present status of endoscopy in the diagnosis, treatment, outcome, and future directions of biliary strictures related to orthotopic liver transplantation from the viewpoint of a clinical gastroenterologists.
