Purpose: Numbers and severity of the injured segments and neurological recovery patterns are both vague and confused following cauda equina syndrome (CES). We evaluated the characteristics of CES according to the causes of the injuries resulting in CES. Subjects and Methods: Thirty-nine cases of CES diagnosed by clinical features and electrophysiological studies were recruited. We investigated segments or roots involved, muscle strength grades of key muscles, external anal sphincter tones, and changing patterns of theses findings. Their characteristics were compared according to the traumatic and non-traumatic lesions. Results: In traumatic lesions, lower segments, such as sacral roots, were involved more frequently and severely (p<O.OOl). In non-traumatic lesions, L5 and Sl roots were more injured and S2,3,4 roots were less injured (p<O.05). However, there was no significant difference of severity among the injured segments in non-traumatic disorders. There was no typical recovery pattern in both traumatic and non-traumatic cases. Conclusions: In traumatic CES, lower segments or roots were injured more prevalently and severely. Relatively, upper segments were more affected in non-traumatic CES.

The study of Electroluminescence has been begun with that the two Germans, B. Gudden & R. W. Pohl in 1920 examined the remaining lights by dint of adding Electric Field at the fluorescent substance, and from 1952 the study became brisk, in 1960 made a peak, and afterward it was diminished. The above facts were appeared through H. E. Ivey`s investigation. The cause was it that the light-efficiency and the brightness were very pessimistic, though the beginning of EL-Study was given in the development of illumination. In 1950, however, with the initiative that C. W. Jerome of Sylvania Co. deviced and announced EL-Lamp, EL-Fluorescent substances were embed and merchandised as EL-Panels, and after a while it was applied to EL-Lamps, Expression Apparatuses, Light Amplifier, Logic Circuit and so on, with which the use frequency got high, and it has been developed as a promising Electronic Industry. But in our country, considering the various conditions, in order to find out the possibility of EL-Production within the home country, Impurity was introduced to ZnS powder, EL of ZnS : Cu, Cl & ZnS : Cu, Mn, Cl could be manufactured, and surveying the Voltage Characteristics, the Frequency Characteristics, and the Spectral Response of the manufactured things, the fundamental technique-problems about the composition of ZnS powder, the introduction of impurity, the formation of thin-thickness, and the construction of Cell, etc were solved gradually. 1. The quantity of Cu must commonly be more one order than in the use of Photoluminescence, as a whole 10(-3)gm,atm/mole ZnS is fitted, and Mn suitable in about 10 times of Cu. 2. Yellow color must dope Cu as well as Mn, when the quantity of Cu fixed to a certain amount, in case that the quantity of Mn is decreased, it be turned into Yellow color, if it is increased, it be taken Orange color. 3. In vacuum flowing HzS gas and baking at the moment, it is said that EL of which brightness is high, but in the air we can secure ZnS : Cu, Cl EL. only. 4. In referring to the conditions 1, 2, 3, I can infer that EL-manufacture if possible in our country.

This study was aimed at identifying on the state and knowledge toward smoking and passive smoking in middle school students. The data were collected from 6th. to 18th. August, 2001. Subject were 125 middle school students who were participated in the Smoking Cessation Program of S Health Agency in Busan. The collected data were analyzed by SPSS program for frequency, percent, mean, and chi-square test. The smoking related state and attitude of subjects were as follows; the number of the smoking students are 10(8.0 %) at present, 19(15.2 %) at past experience, 53(42.4 %) having at present smoking friends, 73(58.4 %) having at present smoking family. Also the smoking starting time of present or past smoking experience was the middle school; 12(9.6 %) and elementary school; 11(8.8 %). They started because of the peer group members; 12(9.6 %), curiosity; 8(6.4 %), and looking good; 7(5.6 %). The passive smoking related state and attitude of subjects were as follows; the number of the passive smoking aware rates are very well level; 71(56.8 %), well level; 54(43.2 %). The exposed experience to passive smoking was always; 38(30.4 %), sometimes; 86(68.8 %), not experience; 1(0.8 5). The place of exposure to passive smoking was game rooms; 67(53.6 %), house; 30(24.0 %), fast food place or cafeteria; 10(8.0 %), and street or in a vehicle ; 3(2.4 %). The main smoker to passive smoking exposure was unknown person; 61(48.8 %). grand parents or parents; 43(34.4 %), brothers or friends; 8(6.4 %), teachers; 4(3.2 %). The chief complant of passive smoking exposure was dyspnea; 36(28.8 %), coughing; 34(27.2 5), dizziness; 21(16.8 %), no symptom; 18(14.4 %). The mostly affected smoker to passive smoking exposure was parents; 52(41.6 %), brothers or friends; 48(38.4 %). The health affected perception to passive smoking exposure was very affected; 109(87.2 %), not affected; 3(2.4 %). In conclusion, it can be well recognized that considerable number of middle school students is exposed to the passive smoking in their homes and by unknown persons, but, their knowledge and attitude toward the exposure to passive smoking is not effective. Therefore, it is hoped that regular smoking education program at school and restriction campaign in home and the public place is necessary.

이지현,이기주,윤성호,부귀범,손현화,박유환,정춘해,김진호,정원영 조선대학교 부설 의학연구소 1998 The Medical Journal of Chosun University Vol.23 No.2

Multiple sclerosis and lupus erythematosus are chronic, potentially disabling diseases of unknown cause. It is a rare occasion that the finding of both diseases occurs in one patient. Because both diseases may affect the central nervous system, it may be difficult at times to differentiate symptoms of lupus erythematosus from those of multiple sclerosis. As far as we know, there was no case report of SLE in multilple sclerosis in Korea. We report a case of multiple sclerosis accompanied by SLE.

Objectives : This study was conducted to estimate the comorbidity rate of ADHD in a group of patients with alcohol dependency and to find out the characteristics of alcoholic patients with ADHD using the diverse clinical and genetic variables. Methods : Eighty five patients with alcohol dependency were recruited from 4 mental hospitals in Kyoung-Nam and Kyoung-Ki province. For the evaluation of ADHD symptoms in both childhood and adulthood, the highly structured Diagnostic Interview Schedule for Children-IV (DISC-FV)-ADHD module was used. The various standardized scales and questionnaires were also applied to evaluate the comorbid conditions and psychopathological status. All the subjects' blood was collected and genetic study for the polymorphism of DRD2, TH, 5-HTTLPR, COMT, ALDH2 was performed. Results : 1) The comorbid rate of definite ADHD in alcoholic patients was 38% (28/85). 2) The frequency of unmarried status was significantly higher in ADHD group compared non-ADHD group. 3) The onset of pathologic drinking and auditory hallucination was significantly earlier in ADHD group than non-ADHD alcholic group. 4) In ADHD alcoholic group, antisocial behavior was more frequently reported, and the score of co-dependency scale, depression/anxiety, aggression and obsessive compulsive drinking scales were significantly higher compared to non-ADHD alcoholic group. 5) No signficant difference was found in the frequency of polymorphic alleles in COMT, DRD2, 5-HTTLPR, ALDH2, TH between ADHD and non-ADHD alcoholic group. Conclusion : In alcoholic patients, the rate of adult type ADHD was higher than expected rate in general population. The alcoholic patients with ADHD suffered from more sever degree of alcohol dependency and earlier alcohol related problems. ADHD-alcoholic group showed higher diverse comorbid psychopathology and lower marital status compared to non-ADHD-alcoholic group. No difference, however, was found in genetic data between two groups.

황진용,최지용,손상균,조용근,채성철,전재은,박의현 慶北大學校 醫科大學 1996 慶北醫大誌 Vol.37 No.4

목적 : 순환기내과 영역은 많은 과로부터 자문의뢰를 받는 영역으로 알려져 있다. 특히 최근 우리나라의 순환기질환의 유형이 변화되고 입원환자가 고령화되면서 동반된 심질환의 유병율도 증가하고있다. 이에 저자들은 타과로 입원하여 순환기내과로 자문의뢰되는 환자의 임상상과 3차병원인 경북대학교병원에서의 순환기내과자문의 유용성 등을 평가하여 향후 순환기질병에 대한 협의진료에 도움을 주고자 본 연구를 시행하였다. 방법 : 1995년 3월부터 순환기내과로 공식자문의뢰된 첫 100명을 대상으로 전향적으로 연령, 의뢰이유, 최종진단명, 수술과의 관련성 여부, 순환기내과의 최종조치, 타과의 순응도 등을 조사하였다. 결과 : 1) 자문을 의뢰한 환자는 평균 58±16(15-89, 중앙치 61)세였고 60세이상의 환자가 57%로 고령의 환자가 많았다. 2) 내과계열 25%, 외과계열 75%로 외과계열의 자문이 많았고 일반외과가 26%로 가장 많았고 내과의 다른 분과가 12%, 신경외과 12%, 정형외과 11%, 흉부외과 11%, 신경과 11% 등의 순이었다. 외과계열중 수술을 시행한 경우는 58례로 이중 응급수술이 13례였다. 술전 위험도 평가를 위한 자문이 38례에서 있었는데 순환기적인 문제로 수술을 받지 못한 경우는 2례(1례는 허혈성 심질환, 1례는 심낭질환)이었다. 이때 응급수술을 제외한 입원일과 술전 자문일파의 간격은 평균 3±7일(입원일-42일)이고 술전 자문일과 수술일과의 간격은 평균 6±4일(1-16일)이었다. 3) 타과의 의뢰이유는 심전도 이상이 36례, 높게 측정된 혈압이 20례, 순환기질환의 과거력 17례, 환자의 증상 때문인 경우가 10례였고 심전도의 이상중에는 부정맥이 18례, 이상 Q파 6례, ST절 이상이 5례, 각차단이 3례의 순이었다. 순환기과거력 중에는 허혈성 심질환이 6례, 현재 혈압은 정상이나 고혈압의 과거력이 있는 경우가 4례 순이었고 환자의 증상은 흉통 6례, 호흡곤란이 3례, 기절이 1례였다. 4) 자문후 최종진단이 가능했던 91례를 진단별(총 97 진단명)로 나누어 보면 고혈압이 28례, 부정맥이 16례, 허혈성 심질환이 14례, 판막질환이 11례, 순환기질환이 아닌경우가 19래였다. 이들중 추적진료가 필요하다고 응답한 경우가 57례였으나 순환기내과 외래에 1번이상 추적진료한 경우는 32례(56%)로 환자의 순응도는 낮았다. 결론 : 순환기내과의 자문의뢰는 고령자에게 많았고 수술과 관련된 경우가 많았으며 심전도의 이상이 의뢰이유로 가장 많았으며 진단별로는 고혈압과 부정맥이 가장 많았다. 그리고 순환기적인문제로 수술을 받지 못한 경우는 드물었고 자문후 지속적인 추적진료를 위해 환자의 교육이 필요하겠다. Objective : Clinical characteristics of the patients with cardiovascular diseases in the general hospital have been changed and prevalance of co-existing cardiovascular disease in the patients who were admitted for non-cardiac diseases has been increased remarkably as the proportion of elderly patients increased rapidly in Korea. We evaluated clinical features of the patients consulted for cardiological evaluation and effectiveness of the consultation in the setting of tertiary general hospital, Kyungpook University Hospital. Method : One hundred patients were studied between January 1995 and January 1996. They were evaluated for the reason of consultation, final diagnosis, final recommendation from cardiologists and its impact on the management of the patients, and compliance of the consulting departments. Results : 1) The ages ranged between 15 and 89 (mean 58±16, median 61) years, 57 patients were male and 43 female. Fifty seven patients were older than 60 years. 2) Consultations from surgical parts were 75 patients. Consultation from general surgery was most frequent (26%), followed by other divisions of internal medicine (12%), neurosurgery (12%) and orthopedic surgery (11%), chest surgery (11%), neurology (11%), obstetrics and gynecology (8%), urology (4%), ophthalmology (2%), dermatology (2%), ENT (1%). Among 75 patients from surgical parts, operation was done on 58 patients, including 13 emergency cases. Preoperative cardiac risk evaluation was the reason of consultation in thirty eight patients, of which operation could not be done in only 2 patients (one had severe ischemic heart disease, the other large pericardial disease). Interval between consultation day and operation day was 6±4 days (1-6 days). 3) Reasons for cardiac consultation were electrocardiographic (ECG) abnormalities in 36 patients, high blood pressure in 20 patients, previous cardiovascular diseases in 17 patients, symptoms of the patients in 10 patients. Among EGG abnormalities, arrhythmias was the reason in 18 patients, abnormal Q waves in 6 patients, ST-T segment abnormalities in 5 patients, bundle branch block in 3 patients. Among previous cardiovascular disease, presence of ischemic heart disease was the reason in 6 patients, previous hypertension in 4 patients. Chest pain was the reason of the consultation in 6 patients, dyspnea in 3 patients, syncope in 1 patient. 4) Definite diagnoses could be made in 91 patients with 96 diagnoses which were hypertension and its complications in 28, arrhythmia with underlying disease in 16, ischemic heart disease in 14. valvular heart disease in 11, non-cardiovascular disease in 19. Cardiological follow up was recommended in 57 patients. However, 25 patients (44%) were lost to follow-up. Conclusion : Cardiological consultation was frequent in the elderly patients. Most frequent reason for consultation was EGG abnormalities. Hypertension or arrhythmia was most common final diagnosis. Inoperability due to cardiovascular problems were rare.

Genetic Variation in the Promoter Region of<i>Chitinase 3-Like 1</i>Is Associated with Atopy

Sohn, Myung Hyun,Lee, Ji Hyun,Kim, Kyung Won,Kim, So Won,Lee, Sung Hee,Kim, Kyu-Earn,Kim, Kyung Hwan,Lee, Chun Geun,Elias, Jack A.,Lee, Min Goo American Thoracic Society 2009 American journal of respiratory and critical care Vol.179 No.6

<P>RATIONALE: Atopy or atopic syndrome is an allergic hypersensitivity subject to hereditary influences. Aberrant expression of chitinase 3-like 1 (CHI3L1), also known as YKL-40 or HC gp-39, is involved in the pathogenesis of inflammatory and allergic diseases. OBJECTIVES: The genetic contribution of CHI3L1 gene to atopic susceptibility was investigated using an integrated population genetic and molecular analysis. METHODS: Genetic variations in CHI3L1 were identified and genotyped in 295 unrelated patients with atopy and 180 control subjects. Serum YKL-40 and IgE levels were analyzed according to genotype. The effects of a promoter polymorphism (g.-247C/T) on promoter activity were examined in reporter and protein binding assays. MEASUREMENTS AND MAIN RESULTS: In the case-control association analysis, the g.-247C/T polymorphism at the promoter region (rs10399805; P = 0.0062) and the IVS7+82C/T polymorphism at intron 7 (rs2275353; P = 0.0056) of CHI3L1 showed a significant association with atopy. Subjects with the g.-247T risk allele had significantly higher serum YKL-40 (P < 0.0001) and IgE (P = 0.012) levels. An in vitro promoter assay using THP-1 human monocyte cells revealed that the C to T conversion at g.-247 induced a more than twofold increase of reporter gene expression. Moreover, the g.-247T allele showed an increased affinity for CCAAT enhancer-binding protein, a well known transcriptional activator, by electrophoretic mobility shift assay. Accordingly, subjects with the g.-247TT genotype showed a 2.5-fold increase in CHI3L1 mRNA expression in peripheral blood cells compared with those with the g.-247CC genotype. CONCLUSIONS: These results strongly suggest that the g.-247C/T polymorphism in the CHI3L1 promoter region is associated with the risk of atopy.</P>

SOHN, EUN JEONG,SHIN, MIN JEA,EUM, WON SIK,KIM, DAE WON,YONG, JI IN,RYU, EUN JI,PARK, JUNG HWAN,CHO, SU BIN,CHA, HYUN JU,KIM, SANG JIN,YEO, HYEON JI,YEO, EUN JI,CHOI, YEON JOO,IM, SEUNG KWON,KWEON, HA Spandidos Publications 2016 INTERNATIONAL JOURNAL OF MOLECULAR MEDICINE Vol.38 No.1

<P>Oxidative stress-induced apoptosis is associated with neuronal cell death and ischemia. The NOL3 [nucleolar protein 3 (apoptosis repressor with CARD domain)] protein protects against oxidative stress-induced cell death. However, the protective mechanism responsible for this effect as well as the effects of NOL3 against oxidative stress in ischemia remain unclear. Thus, we examined the protective effects of NOL3 protein on hydrogen peroxide (H2O2)-induced oxidative stress and the mechanism responsible for these effects in hippocampal neuronal HT22 cells and in an animal model of forebrain ischemia using Tat-fused NOL3 protein (Tat-NOL3). Purified Tat-NOL3 protein transduced into the H2O2-exposed HT22 cells and inhibited the production of reactive oxygen species (ROS), DNA fragmentation and reduced mitochondrial membrane potential (Delta(Psi m)). In addition, Tat-NOL3 prevented neuronal cell death through the regulation of apoptotic signaling pathways including Bax, Bcl-2, caspase-2, -3 and -8, PARP and p53. In addition, Tat-NOL3 protein transduced into the animal brains and significantly protected against neuronal cell death in the CA1 region of the hippocampus by regulating the activation of microglia and astrocytes. Taken together, these findings demonstrate that Tat-NOL3 protein protects against oxidative stress-induced neuronal cell death by regulating oxidative stress and by acting as an anti-apoptotic protein. Thus, we suggest that Tat-NOL3 represents a potential therapeutic agent for protection against ischemic brain injury.</P>

Pneumocystis jirovecii pneumonia (PCP) is a frequent opportunistic infection in patients with acquired immunodeficiency syndrome (AIDS). It usually presents as diffuse ground glass opacities and may lead to life-threatening pulmonary complication. However, patients with AIDS may have variable radiographic manifestation including unilateral infiltration, nodules, cavities, and pleural effusions. To date, PCP presenting with disseminated pulmonary nodules has been rarely reported. We describe the case of a 33-year-old man with AIDS showing disseminated pulmonary nodules with cavities on chest radiograph and CT. We found PCP organism on the bronchoalveolar lavage specimen and confirmed the diagnosis of PCP based on open lung biopsy, which revealed granuloma with cysts of pneumocystis jirovecii. In patients with AIDS, early clinical suspicion of PCP is important since immediate treatment is required to prevent clinical deterioration. PCP should be included in the differential diagnosis of disseminated cavitary nodules in such cases.
