Objectives : As the elderly population is continuing to increase, psychiatric diseases of the elderly are becoming an important social issue. This study looks into the demographical and clinical features of the elderly patients diagnosed with bipolar disorder in a University hospital. Methods : The study subjects include patients admissioned in the closed wards of Soonchunhyang Seoul hospital and Cheonan hospital from March, 2000 to February, 2005 who met the DSM-IV-TR criteria for bipolar disorder at the time of discharge. A total of 146 patients (76 men, 70 women) medical records were studied retrospectively. Subjects older than the age of 50 at time of admission were grouped as the old age group, whereas those who were younger than 50 as the young age group. Also among the old age group, those who had the first onset of episode under the age of 50 were grouped as the early onset group, whereas those who had the first onset after the age 50 were grouped as the late onset group. Results : The number of bipolar disorder patients in the young age group and old age group were 73 and 73 respectively. The number of early onset group and late onset group were 46 and 23 respectively. The old age group had a relatively higher incidence of bipolar II disorder than the young age group. Also in the old age group there was a higher incidence of hypomanic or depressive episode rather than manic episode compared to the young age group. And in the old age group psychotic symptoms were less common and the mean admission length shorter than the young age group. Additionally in the old age group treatment with Lithium monotherapy or with no mood stabilizers at all were relatively common. Among the old age group, late onset group had a higher rate of bipolar II disorder than the early onset group. Conclusion : This study shows differences in the demographical and clinical features among different age groups. But additional research would be required to determine whether the bipolar disorders in the elderly or late onset group are actually a different type of disorder from those of the young.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

The incidence of aseptic meningitis infection is ensuing and threatening the health of children. Enteroviruses are the major agents of aseptic meningitis and identification of virus has been a clue to diagnosis and epidemiology. The outbreak of aseptic meningitis occurred in Pusan, 1998. Patients were concentrated from April through November. Children were more susceptible than adults. Among 306 cases of specimens from stool, throat swab tested, only 7.2% were positive on virus isolation, 12 cases from stool and 10 from throat, respectively. All isolated 7 serotypes of viruses represented cytopathic effect on cultured cells. Three types of echovirus 6, 25, 30 and coxsackievirus B2, B3, B4, B6 were identified by neutralizing anti body test. Isolated coxsackievirus and echovirus were observed by an electron microscope with negative staining.

Aims: The number of elderly patients diagnosed with hepatocellular carcinoma (HCC) has been increasing because the increase in the longevity of the general population. But there is no proper management based on age stratification in elderly patients. We compared clinical characteristics, outcomes and treatment efficacy, safety between oldest-old (aged more than 85 years), middle-old (aged between 80 and 85 years) and young-old (aged between 75 and 80 years) patients with HCC. Methods: We conducted a retrospective cohort study, from January 2010 to December 2016, at Chonnam National University Hospital. A total of 550 elderly patients whose data included demographics, co-morbidity, etiology of liver disease, presence of cirrhosis, staging of HCC, treatment modality and treatment related adverse event were evaluated retrospectively. Also overall survival was assessed in enrolled patient. Results: Fifty one patients (oldest-old; median 87 years old), 153 patients (middle-old; median 82 years old) and 346 patients (young-old; median 77 years old) were diagnosed with HCC. Both oldest- and middle-old patients, compared to young-old patients had significantly lower rate of alcohol-related disease (13.7% vs 20.9% vs 34.1%, P = 0.001). There were no significant difference in underlying sex, body mass index, presence of co-morbidity, hepatitis C-related disease and stage of HCC. The Child-Pugh class (CPT class A 88.9% vs 84.1% vs 83.6%, CPT class B 11.1% vs 15.9% vs 15.0% and CPT class C 0.0% vs 0.0% vs 1.3%, respectively, P = 0.912) and Model for End Stage Liver Disease score (mean MELD score 7.22±3.34 vs 5.88±3.01 vs 5.77±3.14, P = 0.166) were no significant difference between the patients with active treatment. The modified UICC staging (stage I 5.6% vs 17.1% vs 18.6%, stage II 55.6% vs 46.3% vs 47.3%, Stage III 22.2% vs 24.4% vs 24.8%, Stage IV-A 11.1% vs 6.1% vs 4.9% and Stage IV-B 5.6% vs 6.1% vs 4.4%, respectively, P = 0.826) and Barcelona Clinic Liver Cancer staging (stage 0 5.6% vs 9.8% vs 9.3%, stage A 16.7% vs 17.1% vs 22.1%, stage B 27.8% vs 29.3% vs 24.8%, stage C 50.0% vs 43.9% vs 41.2% and stage D 0.0% vs 0.0% vs 2.7%, respectively, P = 0.878) were no significant difference between the patients with active treatment. Furthermore, there were no difference between the age groups in treatment modality (Surgical resection 0.0% vs 3.3% vs 5.2%, P = 0.166; Radiofrequency ablation 2.0% vs 8.5% vs 11.0%, P=0.113; Transcatheter arterial chemoembolization 21.6% vs 34.6% vs 41.6%, P=0.014; Best supportive care 62.7% vs 40.5% vs 29.2%, P < 0.001), adverse event related treatment (P = 0.731) and disease-free survival days (329 .3±309.1 days vs 271.7 ± 414.2 days vs 357.2 ± 511.6 days, P = 0.336). Multivariate analysis showed that age, performance status, CTP class, MELD score, modified UICC staging, presence of portal vein thrombosis and ruptured HCC are risk factors for mortality. Conclusions: Clinician should make an active treatment in elderly patients with HCC not a age but performance status, liver function and disease status of cancer.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

RAW 264.7과 이것이 분화한 파골세포양 세포에서 파골세포 분화관련유전자의 전체적인 유전자 발현을 조사하기 위해 cDNA array 방법을 사용하였다. 1176 cDNA spot grid가 있는 Mouse Atlas cDNA array 결과를 확인하기 위하여 역전사 효소 중합반응 검사를 시행하였다. cDNA array 결과 6개의 유전자가 2.5% 이상 발현이 증가하였으며(PKC beta Ⅱ, POMC, PTEN 등), 16개의 유전자가 2.5%이상 발현이 감소하였다(Osteopontin, Cyclin D1, Cathepsin C, PTMA 등). PKC beta Ⅱ유전자의 역전사-효소 중합 반응 검사 결과 이 유전자를 확인할 수 있었다. 파골세포 분화 결과 RAW 264.7 세포주에 비해 파골세포양 세포에서 PKC beta Ⅱ 유전자가 발현이 많았다. 파골세포 분화 관련 유전자는 RAW 264.7 세포주의 파골세포 분화와 연관을 보였다. To examine the global gene expression of osteoclastogenesis-related genes in RAW 264.7 and its differentiated OCLs through the use of Atlas Mouse cDNA Array 2.1 membranes printed with 1176 well-characterized mouse genes involved in biology. Both samples were screened in parallel using cDNA expression arrays. The array re-sults were additionally validated using RT-PCR. The results of cDNA arrays showed that 6 genes were up-regu-lated >2.5-fold (PKC beta Ⅱ, POMC, PTEN, etc) and 16 genes were down-regulated >2.5-fold (Osteopontin, Cyclin D1, Cathepsin C, PTMA, etc) in both samples at the mRNA level. RT-PCR analysis of PKC beta Ⅱ of these differentially expressed genes gave result consistent with cDNA array findings. The result of osteoclastoge-nesis showed that the PKC beta Ⅱ gene was overexpressed in OCLs compared with RAW264.7 cell line. Osteoclastogenesis-related genes are differentially expressed in RAW264.7 cell line and its differentiated OCLs. its gene overexpression correlates with osteoclast differentiation in RAW264.7 cell line.

Semantic interpretation of image IS incomplete without some mechanism for understanding semantic content that is not directly visible For this reason, human assisted content-annotation through natural language is an attachment of textual description (ie a keyword, or a simple sentence) to image However, keyword-based retrieval is in the level of syntactic pattern matching In other words, dissimilarity computation among terms is usually done by using string matching not concept matching In this paper, we present a solution for qualitative measurement of concept-based retrieval of annotated image We propose a method for computerized conceptual similarity distance calculation in WordNet space. Also we have introduced method that applied similarity measurement on concept-based image retrieval When tested on a image set of Microsofts Design Gallery Live, proposed method outperforms other approach.

Objectives : We report an interim result of conformal radiotherapy in a patient with early stage cancer at the base of the tongue, which developed in a previously irradiated area. Materials and Methods : A 64-year-old male patient was diagnosed with T4NOMO supraglottic cancer. He received 72Gy of radiation therapy from 21 November 1988 to 24 February 1989. He had local failure and underwent a salvage total laryngectomy on 28 August 1989. Subsequently, he did well. In early 1999, he suffered from throat pain. He had a 2.5cm ulcerative mass at the base of his tongue, in the area that had been irradiated previously. Biopsy showed squamous cell carcinoma. After workup, he was diagnosed with base of tongue cancer with T2NOMO. Surgery was not feasible because the morbidity was not acceptable. Since it was difficult to re-irradiate the area with a curable dose using conventional 2D radiation therapy with an acceptable morbidity, we decided to try conformal radiotherapy. We used 7 static beam ports with field sizes from 7×6.4 to 8×8㎠, using 6 and 10MV photons. The fractionation regimen was 1.8Gy, 5 times per week. He received 64.8Gy in 36 fractions from 9 April 1999 to 1 June 1999. Results : In the 21 months since radiotherapy, the patient has not experienced any acute or chronic complications, such as xerostomia. He experienced relief of pain shortly after the start of radiotherapy, showed a complete response, and is still doing well. Conclusion : Conformal radiotherapy can be used to treat cancer that develops within a previously irradiated field, with curative intent.

Korean native goats were experimentally infected with bovine leukemia virus(BLV), and the changes of humoral immune responses were investigated by agar-bel immunodifusion test(AGID), complement dependent antibody cytotoxicity(CDAC), complement fixation test(CF) and virus neutralization test(VN) using syncytium inhibition assay. AGID antibody titers of Group Ⅰ inoculated with FLK-BLV cells were 2 to 4 at 1 month post - inoculation(pi), and persisted for leucocytes from BLV-infected cattle showed the lower AGID antibody titer than GroupⅠ. Cytotoxicity of rabbit complement and normal goat serum against FLK-BLV cells was investigated. Four out of 6 rabbit complements were revealed cytotoxicity index under 5.0%. Range of cytotoxic index of 17 normal goat sera were 11.8 ± 28.6 to 28.6 ± 9.7. CDAC antibody titers of Group Ⅰ were 8 to 16 at 1 month pi and then increased gradually showing maximum titer of 128 at 6 months pi. At 12 months pi CDAC titer were 32 to 128. Group Ⅱ showed relatively lower CDAC titer than Group Ⅰ. CF antibody titer of Group Ⅰ were 4 to 8 at 1 months pi, and then increased up to 32 to 128 at 8 to 10 months pi. GroupⅡ showed the similar patterns of CF titers as Group Ⅰ, but No 3 revealed particularly lower CF titer throughout the experiments. In syncytium assay for detection of BLV in the peripheral lymphocytes, all six heads of goats in Group Ⅰ and Group Ⅱ revealed the positive SA through 12 months showing the maximum SA values of 148. The SA values appeared declining tendency as the observation period passed. VN antibody titer of Group Ⅰ were 16 to 32 1 month pi, and then increased gradually by the maximum titer of 128. Through 12 month experiment, Group Ⅱ manifested the lower VN antibody titer than Group Ⅰ. throughout 12 month period, the control groups that are Group Ⅲ and Group Ⅳ, showed no antibody responses in the above tests.
