Background: Use of antispasmodic medication prior to colonoscopy is controversial but someone believes antispasmodic may improve visualization of colonic mucosa and ease colonoscope insertion. So, we designed a study to assess the effect of premedication with the antispasmodic, hyoscine-N-butyl bromide(Buscopan') on the performance of colonoscopy. Methods: This study was prospective, double blinded, randomized, controlled study, One hundred three consecutive patients were randomized to receive intravenous buscopan lml(n=52) or placebo(n=51) combined with our standard initial medication(me- peridine 50 mg and midazolam 2 mg). Insertion of colonoscopy was timed, and 100 mm visual analogue scales (VAS) were used for asscssing difficulty of procedure, colonic motility, frequency of positional change, frequency of external compression, difficulty of assistance and degree of discomfort experienced by the patients. Results: There were no significant differences of intubation time between buscopan group(mean time, 7.23 min., range 2~15) and placebo group(7.07 min., range 3-25), (p=0.83) and withdrawal time between buscopan group (6.46 min., range 2-22) and placebo group(6.76 min., range 2 25), (p=0.69). Also, there was no significant differences in intubation time between males and females(buscopan; males 7.00 min., females 7.60 min., p=0.34, placebo; males 7.0~5 min., females 7.08 min., p 0.44). The VAS scores checked by endoscopist(p=0.29), assistant(p=0.32) and patient (p=0.15) were not significantly different in both groups. There were no significant differences in intubation time, VAS scores nf endoscopist, assistant, and patients. Conclusion: Premedication with intravenous bu.opan has no advantage on colonoscopy procedure. Use of antispasmodic medication prior to colonoscopy was not considered as recommendable agent.

Choi, Hyuk Soon,Chun, Hoon Jai,Seo, Min Ho,Kim, Eun Sun,Keum, Bora,Seo, Yeon Seok,Jeen, Yoon Tae,Lee, Hong Sik,Um, Soon Ho,Kim, Chang Duck,Ryu, Ho Sang WJG Press 2014 WORLD JOURNAL OF GASTROENTEROLOGY Vol.20 No.27

<P>Endoscopic submucosal dissection is an effective treatment modality for early gastric cancer (EGC), though the submucosal fibrosis found in ulcerative EGC is an obstacle for successful treatment. This report presents two cases of ulcerative EGC in two males, 73- and 80-year-old, with severe fibrosis. As endoscopic ultrasonography suggested that the EGCs had invaded the submucosal layer, the endoscopic submucosal tunnel dissection salvage technique was utilized for complete resection of the lesions. Although surgical gastrectomy was originally scheduled, the two patients had severe coronary heart disease, and surgeries were refused because of the risks associated with their heart conditions. The endoscopic submucosal tunnel dissection salvage technique procedures described in these cases were performed under conscious sedation, and were completed within 30 min. The complete en bloc resection of EGC using endoscopic submucosal tunnel dissection salvage technique was possible with a free resection margin, and no other complications were noted during the procedure. This is the first known report concerning the use of the endoscopic submucosal tunnel dissection salvage technique salvage technique for treatment of ulcerative EGC. We demonstrate that endoscopic submucosal tunnel dissection salvage technique it is a feasible method showing several advantages over endoscopic submucosal dissection for cases of EGC with fibrosis.

Conditioned Media of ASC-17D Sertoli Cells Induce G1-Growth Arrest of DU145 Human Prostate Cancer Cells

Min, Bon Hong,Kang, Sang Wook,Lee, Kwang Ho,Choi, Sang Hyun,Kang, Hyeog,Chun, Boe Gwun The Korea Science and Technology Center 1998 BMB Reports Vol.31 No.5

We studied the effects of ASC-17D rat Sertoli cell-conditioned media (rSCCM) on the proliferation of the DU145 prostate cancer cells. rSCCM was prepared from ASC-17D cells cultured in DMEM/F-12 serum-free media at a nonpermissive temperature of 40℃, which is the condition for the high expression of clusterin. We found that rSCCM could inhibit the proliferation of DU145 cells by arresting the cell cycle in the G1 phase in a dose-dependent manner. This growth arresting activity was abolished by boiling rSCCM for 5 min. The G1 growth-inhibiting activity of rSCCM was also detected in other prostate-originated cancer cells examined (ie., LNCaP and PC-3) but not in other cells (ASC-17D, HepG2, SK-N-SH, and NIH3T3). Western blot analysis of partially purified growth inhibiting fractions with the clusterin antibody showed that the cytostatic factor in rSCCM was not clusterin. This cytostatic factor was semipurified by DEAE-Sepharose, ammonium sulfate precipitation, and Phenyl-Sepharose column chromatography, and was estimated to have a molecular weight of 88 kDa by Sephacryl S-300 gel filtration.

민도준,양동원,민창기,김완욱,이상헌,박성환,김동욱,이종욱,조철수,민우성,김범생,김호연,김춘추 대한조혈모세포이식학회 2001 대한조혈모세포이식학회지 Vol.6 No.1

배경: 기존의 치료에 불응하고 예후가 불량한 자가면역질환 환자들에게 최근 고용량 면역억제 및 조혈모 세포이식이 새로운 치료방법으로 대두되고 있다. 저자들은 다발성 경화증(multiple sclerosis, MS) 및 류마티스 관절염(rheumatoid arthritis, RA) 등 2명의 자가면역질환 환자들에서 자가조혈모세포 이식을 시행하였다. 방법: 말초혈액 조혈모세포 가동화를 위하여 cyclophosphamide (4 g/㎡) 및 granulocyte colony stimulating factor (10 g/kg/day)를 투여하였고, CD34+ 세포를 분리·채집 하였다, 이식 전처치로 MS 환자에서 BEAM 및 antihymocyte globulin (ATG) (3.75 mg/kg), RA 환자에서 fludarabine (180 mg/㎡), ATG (10 mg/kg)와 busulfan (8 mg/kg)을 투여하였다. 결과: 호중구 수가 500/㎕ 이상으로 회복되는 기간은 MS 환자에서 9일, RA 환자에서 15일이었다. 혈소판이 20.000/㎕ 이상으로 회복되는 가간은 RA 환자에서 9일 이었고, MS 환자에서는 혈소판 감소증이 발생하지 않았다. 비혈액학적 독성으로 MS 환자에서 WHO 1도의 오심 및 점막염이 관찰되었다. MS 환자는 이식 6개월 후까지 시력감소가 남아있었으나, 이식전에 관찰되던 감각이상 및 운동장애 등의 신경학적 이상 소견은 더 이상 관찰되지 않았다. RA 환자는 이식 1개월 후 관절 증상 및 검사소견의 호전을 보였다. 결론: 불응성 자가면역질환 환자에서 고용량 면역억제 및 조혈모세포이식은 적은 독성으로 높은 치료효과를 기대할수 있으며, 향후 이 시술의 임상적 의의를 규명하기 위하여 전향적이고 장기적인 연구가 필요할 것으로 사료된다. Background: High-dose immunosuppressive therapy followed by autologous hemathpoietic stem cell transplantation (HSCT) has been proposed as a new approach to treat severe, refractory autoimmune diseases. We describe two patients with refractory autoimmune diseases (one multiple sclerosis 〔MS〕and one rheumatoid arthritis〔RA〕) who underwent T-cell-depleted autologous peripheral bleed stem cell transplantation for the first time in Korea. Methods: We mobilized autologous stem cells with cyclophisphamide (4 g/㎡) and granulocyte colony-stimulating factor (10 ㎍/kg/day). Stem cells were enriched ex vivo using CD34-positive immunoselection and reinfused after high-dose chemotherapy with BEAM and antithymocyte globulin (ATG) (3.75 mg/kg) in MS, or fludarabine (180 mg/㎡), ATG (10 mg/kg) and busulfan (8 mg/kg) in RA. Results: The engraftment with an absolute nerutrophil count greater than 500㎕ occurred on day 9 in MS and 15 in RA, respectively. The time to nontransfused platelet count greater than 2.000/㎕ was 9 day in RA. MS patient did not show ant episode of thrombocytopenia. Regimen-related non-hematopoietic toxicity was minimal. For 6 months since HSCT, them patient with MS had been free from previously existed sensory and motor abnormalities except decreased visual acuity. Then patient with RA and only one tender joint and two mildly swollen joints with improvement in laboratory parameters at one month after HSCT. Conclusion: These results underscore the feasibility and potential efficacy of intensive immunosuppression followed by autologous HSCT for treatment of intractable autoimmune diseases. The durability of remission, however, remains to be clarified.

Skeletal cryptococcosis is an uncommon infection. Cryptococcus is a common cause of meningitis and infects 7∼10% of patients with AIDS. As well as AIDS, the infection may be seen in association with leukemia, lymphoma, Hodgkin's disease, sarcoidosis, tuberculosis and diabetes, also in patients on steroid medication. But there is no case report of skeletal cryptococcosis following allogeneic hematopoietic stem cell transplantation. A 40-year-old woman was admitted to the hospital because of low back pain. She had chronic myelogenous leukemia for 2 years and underwent allogeneic hematopoietic stem cell transplantation 8 months ago. She have been treated with steroid and cyclosporine orally because of chronic graft versus host disease. On examination she was afebrile and had posterior lower lumbar tenderness. But, she had no reduced strength of low extremities. Open biopsy was underwent. Histology demonstrated budding, round-to-oval, refractile yeast-like organisms within debris. The results of a lumbar puncture were unremarkable and cerebrospinal fluid culture failed to grow bacteria and yeast. The patient was treated with amphotericin B (1 gram) and AmBisome□ (2.8 gram) over 6 weeks. Three months after cessation of therapy, the patient was doing well.(Korean J Infect Dis 33:298∼301, 2001)

In this paper, applications of adaptive fuzzy controller to position control of flexible beam are considered. When a flexible beam is rotated by a motor through the fixed end, transverse vibration may occur. The architecture and learning underlying adaptive networks based fuzzy inference system (ANFIS) is presented, which is a fuzzy inference system implemented in the framework of adaptive networks. By using a hybrid learning procedure, the proposed ANFIS can construct an input-output mapping based on both human knowledge and stipulated input-output data pairs. Therefor, a dynamic model for a flexible beam is derived, and then a comparative analysis was made with before learning and after learning adaptive fuzzy controller through an simulation. The results are presented to illustrate the advantages and improved performance of the proposed position control cver the after learning adaptive fuzzy controller.

This study carried out to know the effects of Tetragonia on tumor immunities and the inflammatory responses. The tumor immunities were measured by checking the antibody dependent on cellular cytotoxicity(ADCC) and natural killer(NK) cell activity. The effects of Tetragonia on inflammatory responses were measured by evaluating the amount of reactive oxygen intermediate(ROI) in the neutrophils and macrophages. The innate immunity was evaluated by measuring the phagocytic activity of macrophages. The results obtained were as follows : 1. Tetragonia increased the antigen specific ADCC without affecting antigen non specific NK cell activity in tumor immunities. 2. Tetragonia severely decreased such ROI as O^-_2 and H_2O_2 in both neutrophils and macrophages. 3. Tetragonia increased the phagocytic activity of macrophages. The results of this study suggest that tetragonia might be effective on tumor immunity and such inflammatory diseases as rheumatoid arthritis and allergic diseases.

본 논문에서는 대형 구조물 내의 진동원인 공조기, 펌프 등을 설치, 가동시 구조물의 동적 응답을 예측하고 건물 구조개선 방안을 제시하는데 목적을 두고 있다. 구조물에 대한 동특성 해석은 해석적인 방법과 실험적인 방법으로 이루어지고 있다. 두 가지 방법 중 본 논문에서는 실험적인 방법을 통해서 구조물 동특성 해석을 시도해 보았다. 자체 제작한 대형 충격 해머(Large Impact Hammer)를 이용해서 구조물 바닥부분에 충격을 가진하여 물체에 작용하는 힘과 이로 인하여 발생되는 진동을 각각의 센서에 의해 측정, 분석하여 구조물의 모드형상을 확인하고 고유주파수를 측정하였다. 해석결과에서는 대형 충격 해머를 이용하여 대형 구조물의 동특성 테스트가 가능할 것이라는 것도 예상할 수 있었고, 임의의 진동원 설비가 설치되어 있는 구역에서 구조물의 동특성을 알고 진동원 가동시 발생하는 진동레벨을 측정하여 실험적으로 구하면 임의의 진동원 설비에서 발생하는 동하중이 산출 가능함을 알 수 있었다. 역으로 구조물의 동특성과 진동원의 동하중을 알면 구조물에 발생하는 진동레벨을 예측할 수 있음을 확인하였다. This paper predicted dynamic responses of structures and presented the solution of structural improvements when vibration sources(pump, motor etc.) were activated in structures. The analyses for the dynamic characteristics are the experimental method and theoretical analysis. This study used the experimental method. The mode shapes and natural frequencies are obtained by large impact hammer. It is possible to test the dynamic characteristics of structures using impact hammer. If it is possible to measure the vibration level when vibration sources were operated, it would be possible to compute dynamic weight. On the other hand, the vibration level could be calculated if dynamic weight can be measured.
