Citrobacter species is a gram-negative bacilli that can cause opportunistic infections in immunocompromised hosts. Citrobacter braakii refers to the genomospecies 6 of the Citrobacter freundii complex. There are no detailed studies on infections caused by this newly identified specific genetic species in Korea. We herein report a case of a patient with hepatocellular carcinoma who, after undergoing transcatheter arterial chemoembolization, developed biloma which later progressed to C.braakii sepsis and did not respond to treatment. To our knowledge, this is the first reported case in Korea on C. braakii infection resulting in septic shock in a patient with malignancy in Korea.

Objectives : Impaired processing of facial information is one of the broad ranges of cognitive deficits seen in patients with Schi-zophrenia. We aimed to elucidate the differences in brain activities involved in the process of facial working memory between schizophrenic patients and healthy comparison subjects. Methods : Twelve patients with schizophrenia were recruited along with twelve demographically matched healthy volunteers as a comparison group. Functional magnetic resonance imaging (fMRI) was used to assess cortical activities during the Perfor-mance of a 2-back working memory paradigm using images of neutral faces as mnemonic content. Rcsults : The patient group performed the tasks with reduced accuracy. Group analysis revealed that the left fusiform gyrus, the right superior frontal gyrus, the bilateral middle frontal gyri/insula, the left middle temporal gyrus, the precuneus, the quadrangular lobules and the vermis of cerebellum showed decreased cortical activities in the patient group. On the other hand, an increased level of activation in the lateral prefrontal cortex and the pahetal lobule was observed from the patient group, all in the right hemisphere. Conulusion : A decreased level of activity in the left fusiform gyrus among the patient group implicates inefficient processing of facial information. An increased level of activation in prefrontal and parietal neural networks from the patient group confirms earlier findings on the impaired working memory of patients with schizophrenia.

Cell-mediated immunity frequently becomes severely impaired after burn. However, the cause of postburn immune dysfunction is unclear and controversy exists over both pathophysiology and clinical relevance of these abnormalities. This study was undertaken to invstigate the immune responses in vivo of patients with burn. Levels of soluble IL-2R, a sensitive marker of T-cell activation, were measured in 26 patients with burn. Serum soluble IL-2R levels in patients with burn were significantly higher than those of normal controls. Serum soluble IL-2R levels were correlated closely with the severity of the burn. The burn patients were classified according to the outcome. Patients with fatal outcom always showd a higher soluble IL-2R levels than survivors. Postburn sera significantly suppressed mitogen-indeced lymphocyte proliferation. These data indicate that soluble IL-2R might be useful parameters for monitoring of the clinical course in burn patients.

Acinetobacter species is a non-fermentative aerobic gram-negative coccobacillus that is an important pathogen found in nosocomial infections. Recently, multi-drug resistant Acinetobacter baumannii (MDR-AB) infections have been increasing and pose a serious problem. Most such infections present as bacteremia, pneumonia, or a wound infection; however, CNS infections are very rare. We herein present a case of ventriculitis caused by MDR-AB in a 37-year old man after a neurosurgical intervention. The patient was successfully treated with intrathecal colistimethate.

이유진,연규월,우행원,김영철,임원정 大韓神經精神醫學會 2002 신경정신의학 Vol.41 No.4

연구목적 : 본 연구에서는 의식 소실 유무에 따른 외상후 스트레스 장애 유병율 및 증상, 우울, 불안 증상을 알아보기 위해 외상을 당한 환자를 의식 소실이 있었던 환자군과 의식 소실이 없었던 환자군으로 구분하여 두 집단의 외상후 스트레스 장애의 유병율, 증상 및 불안 정도를 비교해보고자 하였다. 방 법 : 사고를 당하고 1달 이상 경과한 환자 120명(남자 69명, 여자 51명)을 대상으로 하였다. 대상군을 의식 소실 유무에 따라 소실군과 비소실군으로 구분하고 사회인구학적 변수, 사고 당시 의식 소실의 유무, 의식 소실 시간, 사고의 종류, 사고에 대한 기억, 사고의 심각도, 손상 심각도 점수(Injury Severity Score)를 조사하여비교하였다. 또한 외상후 스트레스 장애 척도(Clinician Adminstered PTSD Scale), Beck의 우울증 척도(Beck Depression Inventory), 상태 특성 불안처도- Ⅰ, Ⅱ(State Trait Anxiety Inventory- Ⅰ, Ⅱ)를 이용하여 조사하여 두 군 사이의 외상후 스트레스 장애유병율 및 증상, 우울, 불안 정도를 비교하였다. 결 과 : 통 연구 대상자 120명중 의식 소실이 있었던 환자군(소실군)은 56명(46.7%)이었고 의식 소실이 없었던 환자군(비소실군)은 64명(53.3%)이었다. 총 대상자 120명중 30명(25%)이 외상후 스트레스 장애로 진단되었으며 소실군 56명중 17명(30.4%)이 비소실군 64명중 13명(20.3%0이 각각 외상후 스트레스 장애로 진단되었으나 두 군간의 차이는 통계적으로 유의하지 않았다(x^2=1.607, P>0.05). 외상후 스트레스 장애 증상 척도에서는 소실군에서 사고에 대한 기억 상실, 흥미 상실, 이탈, 감정 둔마, 수면자애, 예민함, 집중력 감소 증상의 빈도가 유의하게 높았다(P<0.05). 비소실군에서느 반복적인 회상과 놀람 반응 빈도가 유의하게 높았다(p<0.05). Beck의 우울증 척도 점수는 소실군에서 38.8±8.8, 비소실군에서 31.0±7.9로 의식 소실을 보고한 환자군의 점수가 유의하게 높았으며(t=-3.16, 0<0.05) 상태 특성 불안 척도-I, II는 소실군에서 각각 44.5±3.3, 44.6±3.9, 비소실군에서 각각 42.9±3.0, 42.3±3.4로 소실군의 점수가 유의하게 높았다(t=-2.75, p<0.05, t=-3.38, p<0.05). 결 론 : 사고 당시 의식 소실이 없었던 환자군과 비교하여 외상후 스트레스장애가 비슷한 빈도로 진단되며 의식 소실이 외상후 스트레스 장애의 발생에 유의한 영향을 미침은 물론 불안 및 우울에도 유의한 영향을 미친다고 할 수 있다. Objectives :This study investigated PTSD prevalence, symptoms, depressed mood and anxiety, comparing two groups of the patients in trauma ; one who had experienced the loss of consciousness(group "A" here after) and the other group of patients who had not(group "B" here after). Method : subjects were 120 patients(age18-66) who had received trauma(traffic accident, fall down) more than 1 month. Before they consisted of 56 patients who had experienced the loss of the consciousness(46.7%) and 64 who had not(53.3%). Men were 69 and women were 51. Clinician administered PTSD Scale, Beck Depression Inventory, State Trait Anxiety Inventory-I, II were administered. The factors such as sociodemographic variables, unconsciousness at the time of trauma, memory about tranmatic accidents were considered. Result : Out of 120 subjects, 30 patients(25%) were diagnosed as PTSD : 17 from 56(30.4%) and 13 from 64(20.3%) were found in the group "A" and "B" respectively. Prevalence of PTSD was higher in the group "A" showed significant difference between two groups(x^2=1.607,p>0.05). The CAPS of group "A" showed significantly high frequency in the loss of interest, detachment, restricted affect, sleep difficulty, irritability/anger. concentration difficulty(p<0.05), while the group "B" scored high in intrusive recall and increased startle. The scores of BDI, STAI-I, II were significantly higher in the group "A"(t=-3.16, p<0.05)(t=-2.75, p<0.05, t=-3.38, p<0.05). Conclusion : PTSD was mre frequent and depressed mood and anxiety appeared more often in the group qho experienced the loss of consciousness. Thus the loss of the consciousness at the time of trauma prones of the aevelopment PTSD and symptom of aepression and anxiety.

김유진,나예린,이현호,오계헌 순천향대학교 기초과학연구소 2021 순천향자연과학연구 논문집 Vol.27 No.1.2

The aim of this work was to investigate the physiological activities of capsaicin-resistant bacterium, Leuconostoc mesenteroides GK-10 isolated from fully fermented mustard leaf kimchi. Initially, the morphological, physiological and biochemical characteristics of strain GK-10 were examined. Based on phylogenetic analysis using 16S rRNA sequencing, the isolate was identified as L. mesenteroides GK-10 and phylogenetic tree of the strain was plotted. L. mesenteroides GK-10 grew well in the different concentrations of capsaicin (0-600 μg/mL). Various physiological activities (e.g., tyrosinase inhibitory activity, ACE inhibitory activity, antioxidant activity, SOD-like activity, depletion of sodium nitrite) of L. mesenteroides GK-10 cultures with different concentrations of capsaicin were evaluated and compared to the cultures of L. mesenteroides DK-3 as a standard strain. According to the results, all of the physiological activities evaluated in this work were considerably higher in L. mesenteroides GK-10 cultures with 600 μg/mL capsaicin compared to L. mesenteroides DK-3 cultures with the same capsaicin concentration, although the physiological activities of GK-10 were higher or lower compared to those of DK-3 in the absence of capsaicin. In consequence, this work showed that L. mesenteroides GK-10 strains can maintain their physiological activities despite the presence of high concentrations of capsaicin.

Chronic neutrophilic leukemia is a rare myeloproliferative disorder and characterizes unusual sustained neutrophilia with splenomegaly but no fever, inflammation, cancer or other cause of neutrophilia. The neutrophilic alkaline phosphatase(NAP), vitamin B_12, uric acid, lactate dehydrogenase(LD), and ferritin are elevated but t(9;22), bcr/abl rearragement are or not noted. The patent was 68 year old male who was subtrochanteric fracture of right femur at 5 days ago. The WBC was 76.8 × 10 exp (9)/L (neutrophil 96.7%, lymphocyte 1.3%, monocyte 1.2%, eosinophil 0.8%), RBC 3.00 × 10 exp (12)/L, hemoglobin 88 g/L, hematocrit 25.6%, and platelet 199 × 10 exp (9)/L at admission. The serum alkaline phosphatase, LD, ferritin, NAP score were elevated but protein, albumin, cholesterol decreased. The WBC(especially neutrophil) were progressively increased number and up to 134.3 × 10 exp (9)/L (neutrophil 96.3 %, 129.3 × 10 exp (9)/L) but no evidences of neutrophilic leukocytosis. The PBS revealed neutrophilic leukocytosis with shift to the left, toxic granules, and some dysgranulopoiesis. He had splenomegaly, no fever and chill. The patient was expired after the 22th admission day.

골뱅이(Buccinum Undatum) 알레르기 : 감작률과 다른 음식물 항원과의 연관성 Sensitization rate and its relationship with other food allergens

이재영,윤성호,서유진,최정희,서창희,남동호,김윤근,민경업,박해심 대한천식 및 알레르기학회 2004 천식 및 알레르기 Vol.24 No.1

Background : The common whelk (Buccinum undatum) is one of the largest and most common snails in the North Atlantic. In Korea and Japan, common whelk is a popular eatable shellfish. Although shellfish has been known as the one of the most common causes of food allergy, there has been no published report on allergenecity and clinical significance of this sea snail. In this study, we determined the sensitization rate to common whelk and its relationship with other food allergens in allergy patients. Method : We carried out the skin prick test (SPT) with commonly consumed food stuffs in Korea including common whelk in 1700 patients over 1 year. The specific IgE to common whelk were detected by enzyme-linked immunosorbent assay (ELISA). ELISA inhibition test using sensitized sera was conducted. Results : SPT to common whelk was positive (≥2+) in 83 (4.9%) patients studied. Twenty-four (38.7%) of 62 SPT-positive patients had high serum specific IgE to common whelk. ELISA inhibition test showed significant inhibitions by abalone as well as by common whelk and, minimal inhibition were noted by shrimp. Significant correlation was also noted in specific IgE levels between common whelk and abalone (r=0.58, F<.05). Conclusion : IgE-sensitization rate to common whelk was 4.9% in allergy patients. Further stuides are needed to evaluate the clinical significance of sensitized patients to common whelk, and to confirm a cross reactivity with abalone. (J Asthma Allergy Immunol 24 : 77-84, 2004)
