        김현수 ( Hyun Soo Kim ),천종운 ( Jong Woon Cheon ),김민수 ( Min Su Kim ),정창길 ( Chang Kil Jung ),김경록 ( Kyung Rok Kim ),최재원 ( Jae Won Choi ),강동우 ( Dong Woo Kang ),김선영 ( Sun Young Kim ) 대한소화기학회 2013 대한소화기학회지 Vol.61 No.2

        Hyun Soo Kim, Jong Woon Cheon, Min Su Kim, Chang Kil Jung, Kyung Rok Kim, Jae Won Choi, Dong Woo Kang and Sun Young Kim1 Departments of Internal Medicine and Pathology1, DongKang Medical Center, Ulsan, Korea Actinomycosis is a chronic suppurative disease and caused by Actinomycosis species, principally Actinomyces israelii, which are part of the normal inhabitant on the mucous membrane of the oropharynx, gastrointestinal tract, and urogenital tract. It usually affects cervicofacial, thoracic and abdominal tissue. Cervicofacial type has the highest percentage of occurrence with 50%. Actinomycosis frequently occurs following dental extraction, jaw surgery, chronic infection or poor oral hygiene. It may also be considered as an opportunistic infection in immunocompromised patients such as malignancy, human immunodeficiency virus infection, diabetes mellitus, steroid usage or alcoholism. But, actinomycosis rarely occurs in adults with normal immunity and rare in the esophagus. We report an unusual case of esophageal actinomycosis which was developed in a patient with normal immunity and improved by therapy with intravenous penicillin G followed oral amoxicillin, and we also reviewed the associated literature.

        ‘헤테로토피아’적 지성, 90년대 시적 주체의한 갈래(1) -장정일을 중심으로

        김정현(Kim Jung-Hyun) 한국현대소설학회 2022 현대소설연구 Vol.- No.87

        This study has a big point of discussion about the authenticity and indefinableness of 90s literature. Under this point of view, this paper discussed Jang Jung-ils intelligence behind ‘sincerity that destroys sincerity’. The core of Jang Jung-ils poem is the masochistic text composition method. Behind this masochistic poetic narrator, the self-consciousness of the poetic subject is implicitly mediated. This symptomatic and symptomatic utterance(écriture) is an important constituent principle in Jang Jung-ils poem. Jang Jung-ils thorough artistic self-consciousness, which tried to reveal his fundamental desires only as signs and surpluses without departing from the principle of producing text, is considered to be the culmination of individuality and internality produced by the 1990s. The desire of the poetic subject, which is revealed only by traces and surpluses in the text, actually corresponds to his efforts in intellectual literature. For Jang Jung-il, the allegorical images of ‘Burning Book’ and ‘death’ show how the poetic subject created his poem through intelligence as a result. Jang Jung-il maintained his literary style and ‘arrogant’ despite the chaos of the 1990s. Jang Jung-ils ‘language’ aspect and peculiarity are the origins of contemporary Korean poetry. The purpose of this study is to examine the multi-layered aspects of authenticity in the 1990s along with the research on Yu Ha.

      • 중증 재생불량성 빈혈 환자에서 신우신염에 대한 광범위항생제치료 중에 속발한 Saccharomyces cerevisiae 진균감염 1예

        김철희,이정호,이정찬,강정현,곽상혁,배광봉,김현수,김종숙,조덕연,김삼용 충남대학교 의과대학 지역사회의학연구소 1999 충남의대잡지 Vol.26 No.1

        Most patients with aplastic anemia who do not respond to immunosuppressive treatment or are not candidates for bone marrow transplantation die of infection or bleeding. The neutropenia in acute leukemia, aplastic anemia, or occurring subsequently to chemotherapy and bone marrow transplantation increases susceptibility to infection. In general, the number of infectious episodes correlate with the degree and duration of neutropenia. Global immunosuppression produced by conditioning for bone marrow transplantation or graft-versus-host disease, is associated with unusual bacterial and fungal pathogens, or serious viral and protozoan infections. In addition, repeated treatment with broad-spectrum antibiotics is associated with the emergence of resistant organisms and fungal diseases because of the altered microbial microenvironment of the host. The incidence of invasive fungal infection caused by Saccharomycetes eerevisiae in immunosuppressed patients is very rare, compared with that of infection by candida or aspcrgillus species. Cases of Saccharomycetes cerevisiae fungemia occurring in the course of treatment with broad-spectrum antibiotics are reported in patients with extensive burn or with prosthetic valve endocarditis. We experienced a case of urinary tract infection by Saccharomycetes cerevisiae in a 27-year old female patient with severe aplastic anemia. We report the case with a review of relevant literatures.

      • 항암제 처리한 백혈병 세포주에서의 Apoptosis 발현

        김삼용,윤소현,김현수,김종숙,윤환중,김진경,조덕연 충남대학교 암연구소 1998 癌共同硏究所 硏究誌 Vol.2 No.1

        The bcl-2 proto-oncogene encodes a 26 kD protein that promotes cell survival by blocking apoptosis. The bax protein is a member of the bcl-2 familly, now known to form heterodimers with the bcl-2 protein. The ratio of bax to bcl-2 is be critical in determining the fate of the cell in response to stimuli that can induce apoptosis. Extract of Pulsatilla Koreana (SB-31) showed promising antitumor activity in vitro with Topo I inhibitory action. In the present study, the relationship between apoptosis and the apoptosis related proteins, bcl-2 and bax were investigated in human leukemic cell lines HL-60, U-937 and CEM-CM3. All anticancer drugs(adriamycin, etoposide, camptothecin, SB-31) induced extensive apoptosis in HL-60, U-937 cells and CEM-CM3 cells. The expression of bcl-2 and bax protein were determined in cell lines by western blotting before and after incubation with anticancer drugs at different time points. 1) In HL-60 or U-937 cell lines, down regulation of bcl-2 and up-regulation of bax were found after incubation with ADR, VP-16 or camptothecin. 2) In HL-60 or U-937 cell lines, no significant change in bcl-2 or bax protein expression resulted after incubation with SB-31. 3) In CEM-CM3 cells, virtually no change was noted in bcl-2/bax expression after incubation with ADR, VP-16, camptothecin or SB-31. It is suggested that different leukemic cell lines use different pathways of apoptosis activation and a given cell may utilize different pathways of apoptosis activation in response to different cytotoxic agents.

        정영정,김연재,김정욱,이상훈,김종철,한세현,장기택 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.1

        최근에 개발된 나노 충전제를 microhybrid 복합레진에 첨가할 때, 나노 충전제 함량이 중합에 미치는 영향을 조사하기 위해, 실험적으로 나노 충전제의 함량을 다르게 제작한 복합레진에서 광중합 후 미세경도를 측정, 분석하여 다음과 같은 결론을 얻었다. 1. 나노 충전제의 함량이 2%, 3%인 군은 0%, 1%인 군에 비해 중합된 면의 미세경도가 유의하게 높았으나(p<0.01), 그 차이는 크지 않았다. 2. 나노 충전제의 함량이 높을수록 레진 시편의 하면에서의 미세경도는 증가하였으며, 나노 충전제의 함량이 0%, 1%, 2%간에, 0%, 1%, 3%간에 유의한 차이가 있었고(p<0.01), 2%와 3%간에는 차이가 없었다(p<0.05). 3. 레진 시편의 상면과 하면의 미세 경도 차이는 나노 충전제 함량이 높을수록 감소하였으며, 나노 충전제의 함량이 0%, 1%, 2%간에, 0%, 1%, 3%간에 유의한 차이가 있었고(p<0.01), 2%와 3%간에는 차이가 없었다(p<0.05). The objective of this study was to evaluate the effects of nanofiller content on the microhardness and polymerization of experimental microhybrid composites. The nanofiller contents in the experimental composites were varied (0%, 1%, 2%, 3%), while the total filler content remained constant as 76 %wt. We obtained the following results: 1. The microhardness of the top surface for the 2%, 3% nanofilled microhybrid composites were significantly higher than those for the 0%, 1% nanofilled composites (p<0.05), but the difference was not great. 2. The microhardness of the bottom surfaces significantly increased with an increase in the nanofiller level (p<0.05), except between the 2% and 3% nanofilled groups (p>0.05). 3. As the nanofiller level increased, the difference beween microhardness of top and bottom surfaces significantly decreased (p<0.05), except between 2% and 3% nanofilled groups (p>0.05).

        Mouse의 치아 발육시 Runx2의 발현 양상

        김태완,류현모,남순현,김영진,김현정 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.4

        Runx2는 runt gene family에 속하는 전사조절 인자로써 뼈의 형성과 골아세포의 분화에 중요한 역할을 담당하고 있다. Runx2-haploinsufficency는 쇄골의 저형성 및 두개 봉합의 지연을 특징으로 하는 쇄골두개 이형성증을 일으키며, 치아에 있어서는 법랑질의 저형성, 영구치 맹출지연 등을 보인다. 이에, 치아의 발육 및 맹출에 미치는 Runx2의 영향을 알아보기 위해 in situ hybridization 방법으로 태생 1, 4, 7, 14. 21일 된 쥐의 하악 및 제1대구치를 사용하여 실험을 실시하였다. Runx2-full length는 태생 1일과 4일에 치낭 및 주위조직에 보이지만 Runx2-typeⅡ는 보이지 않았다. Runx2-full length는 태생 7일에 치관 교합면 부위의 법랑모세포에 발현하였고, 1주일 후인 태생 14일에는 백악법랑경계 상방의 치관인 접면 법랑모세포에서 발현되었다. 이에 반해 Runx2-typeⅡ는 법랑모세포에서 발현하지 않았다. 또한 태생 21일에서는 두가지 이성질체가 모두 하악골에서 발현을 보였다. 이런 결과를 종합해볼 때, Runx2-full length는 치아의 맹출과 연관이 있으며, 법랑모세포의 분화 및 이로 인한 법랑질형성에 영향을 주지만 Runx2-typeⅡ는 하악골의 형성에만 영향을 미치는 것으로 사료된다. Runx2 is a transcription factor in homologous with Drosophila runt gene and it is essential for bone formation during embryogenesis and a critical gene for osteoblast differentiation and osteoblast function. Runx2-haploinsufficency causes cleidocranial dysplasia (CCD). CCD is an autosomal-dominant inherited disorder characterized by hypoplastic clevicle and delayed ossification in fontanelles and wormian bones. Dental defects are possibly shown to CCD patients : multiple supernumerary teeth, irregular and compressed permanent tooth crowns, hypoplastic and hypomineralized defects in enamel and dentin, an excess of epithelial root remnants, the absence of cellular cementum, and abnormally shaped roots. In addition, delayed eruption of the secondary dentition is a constant finding. The aim of this study is to evaluate the role of Runx2 in the tooth development and eruption through analyzing the expression pattern of Runx2 by in situ hybridization during crown (late bell stage) and root formation of tooth, using postnatal day 1, 4, 7, 14 and 21 mice mandibular molar teeth. mRNA of Runx2-full length is expressed in dental follicle and surrounding tissue at postnatal day1 and 4. At post-natal day 7, it is expressed in ameloblasts of occlusal surface of enamel and bone area surrounding the tooth. In comparison with previous stage, at postnatal day 14, it is expressed in ameloblasts of proximal surface of enamel. At postnatal day 21 it's expression is observed only in bone area. mRNA of Runx2-typeⅡ is not expressed At postnatal day 1 and 7. At postnatal day 14 and 21, it's expression is observed in the bone area. In this study, we suggest that Runx2 have a relation of ameloblasts differentiation and an important role to tooth eruption made by dental follicle during intraosseous eruption stage. Also we can confirm that Runx2 has a role to bone formation.

      • The Variation of Winter Buds among 10 Selected Populations of Kalopanax septemlobus Koidz. in Korea

        Kim,Sea-Hyun,Ahn,Young-sang,Jung,Hyun-Kwon,Jang,Yong-Seok,Park,Hyung-Soon 한국자원식물학회 2002 Plant Resources Vol.5 No.3

        The objective of this study was to understand the conservation of gene resources and provide information for mass selection of winter bud characters among the selected populations of Kalopanax septemlobus Koidz using analysis of variance(ANOVA) tests. The obtained results are shown below; 1. Ten populations of K. septemlobus were selected for the study of the variation of winter bud characters in Korea. The results of the analysis of variance(ANOVA) tests shows that there were statistically significant differences in all of the winter bud characters among those populations. 2. Correlation analysis shows that width between Height and DBH(Diameter at breast height) characters have negative relationship with all of the characters, as ABL(Apical branch length), ABW(Apical branch width), AWBL(Apical branch winter bud length), AWBW(Apical branch winter bud width), ABT(Apical branch No. of thorns), ABLB(Apical branch No. of lateral bud) and LBL(Lateral branch length), LBW(Lateral branch width), LBT(Lateral branch No. of thorns), LBLB(Lateral branch No. of lateral bud). 3. The result of principal component analysis(PCA) for winter buds showed that the first principal components(PC s) to the fourth principal component explains about 78% of the total variation. The first principal component(PC) was correlated with AWBW, LWBW, and LBL and the ratio of ABL/ABW and LBL/LBW out of 16 winter bud characters. The second principal component correlated with ABL, ABW, ABLB, LWBL(Lateral branch winter bud length), and LBW and the ratio of AWBL/AWBW. The third principal component correlated with ABL, ABW, LWBL, LBL, and the ratio of LBL/LBW. The fourth principal component correlated with LBL and the ratio of LWBL/LWBW(Lateral branch winter bud width), LBL/LBW. Therefore, these characters were important to analysis of the variation for winter bud characters among selected populations of K. septemlobus in Korea. 4. Cluster analysis using the average linkage method based on 10 selected populations for the 16 winter bud characters of K. septemlobus in Korea showed a clustering into two groups by level of distance 1.1(Fig. 3). As can be seen in Fig. 3, Group I consisted of three areas(Mt. Sori, Mt. Balwang and Mt. Worak) and Group Ⅱ contisted of seven areas(Suwon, Mt. Chuwang, Mt. Kyeryong, Mt. Kaji, Mt. Jiri, Muan, and Mt. Halla). The result of cluster analysis for winter bud characters corresponded well with principal component analysis, as is shown in Fig. 2.

      • 人 諸臟器 Alkaline Phosphatase Isoenzyme의 電氣泳動 및 定量

        金在植,金京善,金重明,金榮泰,蔣卓仙,李鉉基 慶北大學校 醫科大學 1980 慶北醫大誌 Vol.21 No.2

        著者들은 家兎와 人體로부터 採取한 血淸과 諸臟器組織을 使用하여 ALPI 電氣泳動像을 觀察하고 生化學的 定量法을 利用하여 ALP의 活性度를 測定試圖하였으며 臟器特異性 沮害因子에 對한 影響을 觀察하였다. 家兎 血淸 및 諸臟器組織 ALPI電氣泳動에서 血淸은 ±의 活性度를 가진 α2와 α2/β分劃을 나타내었으며 肝組纖은 血淸보다 빠른 移動度를 가진 ??의 α_1과 α_2分劃을 나타내었다. 그리고 肝, 骨, 腎 淋巴腺, 脾臟 및 腸組織에서는 顯著하게 높은 活性度를 나타내는 各各 서로 相異한 分劃을 볼 수 있었으며 人體諸 臟器와大體로 類似하였으나 家兎 血淸의 ALP는 사람에서 와는 다르게 肝組織의 分劃과 一致하지 않고 오히려 骨組織과 더 잘 一致되는 것 같았다. ALPI 活性度에 있어서 家兎의 諸臟器는 生化學的 定量法으로 腎 ALP의 活性度가 49.5B.L. units로 다른 臟器組織에 비하여 顯著하게 높았으며, 그 다음은 脾臟, 脊椎骨, 肝, 肺淋巴腺 및 脾 順으로 높은 活性度를 나타내었으며 人體에 있어서는 胎盤, 骨, 小賜, 脾臟, 肝 및 腎臟의 順으로 높았다. 臟器 特異性 沮害因子에 對한 影響에 있어서 胎盤分劃은 特有하게 耐熱性을 나타내었고 보다 urea低抗性이며 肝分劃은 neuraminidase에 對하여 移動度의 遲延을 招來하였다. The studies upon cellulose acetate microzone electrophoretic patterns, quantitative estimation and effects of organspecific inhibitor on ALP isoenzyme of rabbit and human sera and various organ tissues were performed. On electrophoretic pattern the tissue ALP from the liver bone kidney lymph node spleen and intestine showed the characteristic fraction of high activities. The electrophoretic mobility of rabbit serum ALP was not correspond to the liver ALP as observed in human serum and it appeared to be rather corresponded to the bone ALP, which seemed to be the origin of ALP in serum of rabbit. In the quantitative measurement of tissue ALP activity the kidney ALP showed the highest level and the activity of the skeletal muscle ALP was the lowest(1.5 B. L. units), while higher activities were observable in placenta, bone, intestine, spleen, liver and kidney in order. On the effect of organ specific physico chemical agents the placental ALPI was highly stable to the heat and relatively resistant to urea while other organ ALPI were on the contrary. The neuraminidase seemed to effect to the motility of liver fraction.
