        Objectives: This study was performed to find the desirable remaining time of needle in the acupuncture treatment. Methods: The 21 volunteers were given acupuncture at LU9 vertically and needles were remained for 2 min, 10 min, 15 min, 30 min, respectively. The thermographic change induced by acupuncture was measured with Digital Infrared Thermographic Image at the following acupoints: LU11, LU10, LU9, LU8, LU5, LU1, and PC7. The statistical significance of thermographi change was evaluated using paired t-test and post hoc Wilcoxon test. Results: The most significant changes after acupuncture were produced when needles were remained for 10 min or 15 min. LU11, LU5, LU1, and PC7 were the point at which all of the remaining time produced significant change commonly. At LU11, the biggest change was produced when needle was remained for 15 min, while at LU5, LU1, and PC7, the biggest change was produced when needle was remained for 30 min, and the smallest change was produced when needle was remained for 10 min at all of acupoints of LU11, LU5, LU1, and PC7. The unbalance between left side and right was decreased the most largely in 15 min group. Conclusions: The results of this study suggest that the desirable remaining time of acupuncture needle might be 15 min.

      • 불응성 자가면역질환에서의 자가조혈모세포이식

        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.

        개의 췌도분리에서 췌장의 팽창과 콜라겐 분해요소

        이상훈,김성주,박정환,김종성,오승훈,한진수,정인경,양태영,김동준,김광원,이문규,민용기,이명식,정재훈,함종렬 대한당뇨병학회 2000 Diabetes and Metabolism Journal Vol.24 No.2

        Backgrounds: One of the main problems conditioning the outcome of islet transplantation is the ability to separate a sufficient number of viable islets with preserved function. Islet purification is critically affected by all of the isolation stages. Thus, it is necessary to set up the standard isolation method that islets are separate well from acinar without compromising islet yield and viability. Methods: Twenty three adult mongrel dogs were used for the experiment of total pancreatectomy with islet isolation. The islets were properly isolated by a modified Recordi method. The obtained islets were further purified by centrifugation on discontinuous gradients using cell separation system (Model 2991, Cobe, Lakewood Colo). We evaluated islet number (islet equivalent number, 150 um equivalents/kg of recipient body weight, IEq/kg), purity, cell volume, viabilty, recovery rate, and comparison of outcome according to the isolation conditions. Results: 1) The mean of islet numbers before purification were 13543±9431Eq/kg, digestion times were 13.8±2.6 min., digestion temperature was 37.4±0.2℃, purity was 59.7?.0%, viability was 90.0±2.1%, cell volume was 4.7±1.1 mL, islet number after purification were 4064±361 IEq/kg, and recovery rate was 29±2.9%. 2) Isolated islet numbers were different according to the degree of pancreas distension with collagenase, digestion temperature, and digestion time. 3) The best conditions for islet isolation were above 37.5℃ in temperature at recirculation of collagenase, within 12 min in digestion time and well distended pancreas with collagenase. 4) According to multiple regression adjusted by variable factors, the degree of pancreas distension with collagenase and digestion time were independently associated factors for successful islet isolation. Conclusions: In this study, we concluded that the degree of pancreas distension with collagenase and digestion time were independent factors for successful islet isolation and the best conditions for islet isolation were above 37.5℃ in temperature at recirculation of collagenase, within 12 min in digestion time and well distended pancreas with collagenase.

        Genomewide Expression Profile of Forsythia Suspensa on Lipopolysaccaride-induced Activation in Microglial Cells

        Sohn, Sung-Hwa,Ko, Eun-Jung,Kim, Yang-Seok,Shin, Min-Kyu,Hong, Moo-Chang,Bae, Hyun-Su The Korean Society of Toxicogenomics and Toxicopro 2008 Molecular & cellular toxicology Vol.4 No.2

        Microglia, which is the primary immune effector cells in the central nervous system, constitutes the first line of defense against infection and injury in the brain. The goal of this study was to determine the protective (anti-inflammation) mechanisms of forsythia suspense (FS) on LPS-induced activation of BV-2 microglial cells. The effects of FS on gene expression profiles in activated BV-2 microglial cells were evaluated using microarray analysis. BV-2 microglial cells were cultured in a 100mm dish $(1{\times}10^7/dish)$ for 24hr and then pretreated with $1{\mu}g/mL$ FS or left untreated for 30 min. Next, $1{\mu}g/mL$ LPS was added to the samples and the cells were reincubated at $37^{\circ}C$ for 30 min, 1hr, and 3hr. The gene expression profiles of the BV-2 microglial cells varied depending on the FS. The oligonucleotide microarray analysis revealed that MAPK pathway-related genes such as Mitogen activated protein kinase 1 (Mapk1), RAS protein activator like 2 (Rasal2), and G-protein coupled receptor 12 (Gpr12) and nitric oxide biosynthesis-related genes such as nitric oxide synthase 1 (neuronal) adaptor protein (Nos1ap), and dimethylarginine dimethylaminohydrolase 1 (Ddah1) were down regulated in FS-treated BV-2 microglial cells. FS can affect the MAPK pathway and nitric oxide biosynthesis in BV-2 microglial cells.

        Genome Wide Expression Profile of Agrimonia pilosa in LPS-stimulated BV-2 Microglial Cells

        Sohn, Sung-Hwa,Ko, Eun-Jung,Kim, Sung-Hoon,Kim, Yang-Seok,Shin, Min-Kyu,Hong, Moo-Chang,Bae, Hyun-Su The Korean Society of Toxicogenomics and Toxicopro 2009 Molecular & cellular toxicology Vol.5 No.1

        Microglial cells constitute the first line of defense against infection and injury in the brain. This study was conducted to evaluate the protective mechanisms of Agrimonia pilosa (AP) on LPS-induced activation of BV-2 microglial cells. The effects of AP on gene expression profiles in activated BV-2 microglial cells were evaluated using microarray analysis. BV-2 microglial cells were cultured in a 100 mm dish ($1{\times}10^7/mL$) for 24 hr and then pretreated with 1 g/mL AP or left untreated for 30 min. Next, 1 g/mL LPS was added to the samples and the cells were reincubated at $37^{\circ}C$ for 30 min, 3 hr and 6 hr. The gene expression profiles of the BV-2 microglial cells varied depending on the AP. The microarray analysis revealed that MAPK signaling pathway-related genes were down-regulated and IL10 gene was up-regulated in AP-treated BV-2 microglial cells. AP can affect the inflammatory response and MAPK pathway in BV-2 microglial cells.

        Genome Wide Expression Profile of Asiasarum sieboldi in LPS-stimulated BV-2 Microglial Cells

        Sohn, Sung-Hwa,Ko, Eun-Jung,Kim, Yang-Seok,Shin, Min-Kyu,Hong, Moo-Chang,Bae, Hyun-Su The Korean Society of Toxicogenomics and Toxicopro 2008 Molecular & cellular toxicology Vol.4 No.3

        Recent studies suggest that activated microglial cells play an essential role in the inflammatory responses and neurodegenerative disorders such as Alzheimer’s and Parkinson’s disease. This study was conducted to evaluate the protective mechanisms of Asiasarum sieboldi (AS) on LPS-induced activation of BV-2 microglial cells. The effects of AS on gene expression profiles in activated BV-2 microglial cells were evaluated using microarray analysis. BV-2 microglial cells were cultured in a 100 mm dish ($1{\times}10^7$/mL) for 24 h and then pretreated with 1 ${\mu}g$/mL AS or left untreated for 30 min. Next, 1 ${\mu}g$/mL LPS was added to the samples and the cells were reincubated at $37^{\circ}C$ for 30 min and 1 hr. The gene expression profiles of the BV-2 microglial cells varied depending on the AS. The microarray analysis revealed that MAPK signaling pathway-related genes were downregulated in AS-treated BV-2 microglial cells. AS can affect the neuroinflammatory-related pathway such as MAPK signaling pathway in activated BV-2 microglial cells.

        양형인 ( Hyung In Yang ),김완욱 ( Wan Uk Kim ),민도준 ( Do Jun Min ),박성환 ( Sung Hwan Park ),홍연식 ( Yeon Sik Hong ),이상헌 ( Sang Heon Lee ),조철수 ( Chul Soo Cho ),김호연 ( Ho Youn Kim ) 대한류마티스학회 2000 대한류마티스학회지 Vol.7 No.4

        Objective: To investigate the dosage of bovine type II collagen (BnCII) for the induction of oral tolerance in CIA animals, and to verify the changes of immune response and TGF-β production of mesenteric lymph node cells in tolerized CIA animals. Methods: Oral tolerance was induced by feeding of variable doses (5㎍, 10㎍, 20㎍ and 40㎍) of BnCII to DBA/1 mice 4 times per week during 2 weeks, and control mice were given ovalbumin (1000㎍), before immunization. We examed clinical assessment; incidence of arthritis, severity of arthritis, arthritic limb by visual analysis. IgG antibodies to BnCII were measured by ELISA, T cell responses to BnCII and PHA were quantified by antigen (CII)-induced 3H-thymidine incorporation into lymphocytes of mesenteric lymph node, draining lymph node, and spleen. TGF-β in supernatants obtained from lymph node culture medium was measured by ELISA. Results: Arthritis limbs were observed in 100% of control at 5 weeks after subcutaneous BnCII injection. The incidences of CIA in all tolerized group were significantly lower than that in control 5 weeks after immunization (control 100% vs. 5㎍ feeding group: 50%, 10㎍ feeding group: 50%, 20㎍ feeding group: 50%, 40㎍ feeding group: 55.5%, P<0.01). In comparison to control, mean articular indices were lower in all tolerized groups (control 5.13: 5㎍ feeding group 3.50, 10㎍ feeding group 2.75, 20㎍ feeding group 2.87, 40㎍ feeding group 2.63, P<0.05). Arthritic limbs were also significantly lower in tolerized groups (control 58.3: 5㎍ feeding group 20.8, 10㎍ feeding group 16.7, 20㎍ feeding group 20.8, 40㎍ feeding group 20.8, P<0.05). The titers of IgG antibody to CII were lower in tolerized group than that in control [tolerized group; median 10 (min. 0, max. 48), control; median 33 (min. 8.6, max. 101), P<0.05]. The proliferative responses to BnCII were significantly suppressed in tolerized (control 8010±2319cpm, tolerized group 4500±2060cpm, P<0.01). High TGF-β production was noted in tolerized group (control; 28pg/ml, BnCII feeding group; 73pg/ml). Conclusion: Oral tolerance in DBA/1 mice was successfully induced from low doses of BnCII (5㎍) and suppressed T and B cell function in conjunction with increased TGF-β production may play an important role for the induction of CII induced oral tolerance in DBA/1 mice.

        C -11 및 F - 18 표지 콜린의 합성과 체내동태에 관한 연구

        전권수,유국현,김상욱,임상무,홍성운,서용섭,양승대,안순혁,허민구 대한핵의학회 2001 핵의학 분자영상 Vol.35 No.3

        Objectives: Recently, [methyl-(11)^C]-(β-Hydroxyethyl)trimethylammonium ([(11)^C]choline) has been discovered to be a very effective tracer in imaging various human tumors using positron emission tomography. Because of the short half-life of C-11, it is very difficult to use in a routine imaging procedure and needs a frequent synthesis of [(11)^]choline. This can be supplemented by the substitution of [(11)^Ccholine with [methyS-18]fluorocholine. Here, we would like to report cell uptake and biodistribution of [(11)^Ccholine and [(18)^F]fluorocholine as a basic study. Methods [(11)^C]Choline was prepared by the treatment of [(11)^C]CHzI with N,N-dimethylaminoethanol and [18F]fluorocholine was synthesized from reaction of CHzBr[18F]F with N,N-dimethylaminoethanol. The radiochemical purity was checked by high performance liquid chromatography (HPLC). The biodistribution of [(11)^C]choline and [(18)^F]fluorocholine was determined in balb/c mouse at 5 min, 20 min, 40 min and 80 min. The cell uptake wa measured using glioma (9L) and colon adeocarcinoma (SW620). Results: The radiochemical purity was more than 98% after purification. In the liver, uptake did not change over time the uptake was 20/ID/g for [C]choline and 13%ID/g for [(18)^F]fluorocholine. In the kidney, radioactivity decreased over tirne the uptake was 15%1D/g for [(11)^Ccholine and 20%ID/g for [(18)^F]fluorocholine, 80 min post-injection. The cell uptake of [(11)^Ccholine was 4.93% for glioma (9L) and 18.69F for colon adenocarcinoma (SW620). For [(18)^F]fluorocholine, 1.77% for glioma (9L) and 2.77% for colon adenocarcinoma (SW620). Conclusion: [(11)^CCholine and [(18)^F]fluorocholine showed a different cell uptake tendency, depending on cancer cell line. (Korean J Nucl Med 200135:185-191)

      • 정신병리적 언어행위의 형식적 특징규명을 위한 기초연구

        민형원,홍성기,정승아,이장한,양병환 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.4

        연구목적 : 정신분열병집단과 정상집단의 사고형태의 차이를 언어철학적으로 접근하여 이해하고 이를 바탕으로 사고형태를 측정하는 도구를 개발하고자 한다. 방 법 : 1997년의 예비실험에서 얻은 결과를 중심으로 새로운 작품사진(具象, 抽象의 彫刻과 繪畵)을 약 50장을 선정한 후 반응의 용이성과 다양성을 기준으로 최종 10개의 작품을 실험도구로 결정하였다. 피검자는 1999년 2월부터 동년11월까지 대학병원 신경정신과에 입원한 24명(정신분열병)과 정상대조군으로 19명의 일반인들이 실험에 참가하였다. 피검자들은 제시되는 작품의 제목을 붙이도록 요구받았으며, 피검자의 세 가지 반응측면 즉 반응의 방식, 반응이 지칭하는 작품의 범위, 그리고 반응이 지칭하는 대상의 구체성 혹은 추상성 여부로 구분하여 전체 7가지 양상으로 기호화하였고 각 반응를 직접과 간접으로 구분하였다. 피검자에게 실험을 실시한 후 기호화하여 집단간 빈도분석을 실시하였다. 결 과 : 1) 정신분열병집단이 정상집단보다 직접속성, 단순기술의 반응이 많은 반면에, 정상집단의 경우 투사가 결합된 직접속성, 간접속성, 간접연상, 그리고 개념의 형성에 필요한 일반화가 많았다. 2) 제목과 이 제목이 지칭하는 작품의 범위관계에 대한 정신분열병집단과 정상집단의 반응빈도는 의미 있는 차이를 보이지 않았으나 두 집단 모두 작품의 부분보다는 전체를 보고 제목을 정하는 경향이 높았고, 비교적 정신분열병집단이 제목을 작품전체를 보고 단순하게 반응하는 경향이 있는 반면에 정상집단은 작품의 일부분을 보고 이를 일반화하는 경향이 많았다. 3) 정신분열병집단과 정상집단 모두 제목의 추상성보다는 구체성이 우세한 경향을 보였으나, 정신분열병집단(95.3%)이 정상집단(71.4%)에 비해서 보다 더 제목의 구체성이 두드러졌으며 정상집단(28.6%)은 정신분열병집단(4.7%)에 비해서 전체 반응빈도에서 제목의 추상성이 더 우세하였다. 4) 정신분열병집단이 정상집단보다 사고의 직접성이 더 높았고(73.5%), 정상집단은 사고의 간접성이 더 높았다.(58.7%). 결 론: 1) 정신분열병집단이 정상집단에 비하여 추론과정과 사고의 단계성이 없는 직접적이고 단순한 형태의 사고형태나 언어표현이 확연히 드러났다. 또한 정신분열병집단이 사물을 지각하고 이를 표현하는데 있어서도 사물의 전체를 보고 단순하게 반응하거나, 구체적이고 직접적인 표현이 많은 것으로 보인다. 2) 본 연구를 통해 개발된 실험도구를 좀 더 넓은 범위의 대상자에게도 반복 적용하여 연구함으로써 지속적인 신뢰도와 타당성을 높일 수 있을 것이다. 또한 개별적 차이에 대한 연구를 병행함으로써 개인간의 혹은 동일한 인물의 시간경과에 따른 사고방식의 차이를 검사할 수 있는 방법으로 정착될 필요가 있다. 3) 비록 양집단 사이의 확연한 차이에도 불구하고 실험도구의 신뢰성을 객관적으로 확보하기 위하여 사고형태 및 언어적 표현에 영향을 미치는 것으로 추정되는 지적능력, 교육연한, 그리고 문화적 경험을 좀 더 고려한 추가연구가 필요할 것으로 생각된다. Objective : The purpose of this study was to identify differences in thinking between schizophrenic patients and healthy subjects with linguistic-philosophical approach and to develop a tool to measure pathological thinking. Methods : Approximately 50 cards(pictures of either representational or abstract sculptures and paintings) from the previous experiment(1997) were carefully examined and 10 cards were selected based on their variety and promptness of the response. Twenty-four schizophrenic patients and 19 healthy subjects participated in this experiment. Participants were required to give a title to each picture. Their responses were analysed based on the forms of thinking, abstractness(or concreteness) and the category of the title. Each response was also coded either direct of indirect. Results : 1) Schizophrenic patients emitted more direct and simple descriptive responses whereas healthy subjects showed projection-related direct traits, indirect traits, indirect association and generalization. 2) Both groups tended to utilize the whole rather than parts. Schizophrenic group depended more on the whole pictures than healthy group. Healthy subjects showed more generalization tendency with parts. 3)Both groups preferred concrete titles to abstract ones. Schizophrenic group(95.3%) used more concrete titles than healthy group(71.4%) and healthy group(28.65%) used more abstract titles than schizophrenic group(4.7%). 4) Schizophrenic patients(73.5%) showed more directness in thinking than healthy subjects, whereas healthy subjects(58.7%) more indirectness. Conclusions : 1) Schizophrenic patients clearly showed direct and simple forms of thinking and expressive language, lacking reasoning, and systematic processing. Additionally, schizophrenic patients simply responded to the whole and used concrete and direct expression. 2) Replication study is warranted to improve reliability and validity of the tool we developed. Research on individual differences needs to be conducted to measure differences among individuals and change over time in an individual. 3) Further study on the factors which might be related to forms of thinking and language expressions, such as intelligence is warranted.
