Objectives : To assess clinical improvement and change in plasma brain-derived neurotrophic factor(BDNF) level after repetitive transcranial magnetic stimulation(rTMS) in patients with treatment-resistant schizophrenia. Methods : Seven patients with DSM-IV schizophrenia, who were proven to be treatment-resistant, were treated with 15 sessions of rTMS for three weeks as an adjuvant therapy to antipsychotic treatment. Clinical improvement and change in plasma BDNF level were measured after the treatment period. The symptom severity was assessed with the Positive and Negative Syndrome Scale(PANSS) and the Korean Version of Calgary Depression Scale for Schizophrenia(K-CDSS) at baseline and 7 days after the treatment. Plasma BDNF level was measured by enzyme-linked immunosorbent assay(ELISA) at baseline and 7 days after the treatment. Results : After the rTMS treatment, there was no significant improvement in PANSS total score(Z=-1.693, p=0.090) and no significant change in plasma BDNF was found(Z=-1.183, p=0.237). Negative correlations were found between percentage change in PANSS positive subscale score and duration of illness(rho=-0.991, N=7, p<0.0005, two-tailed), and PANSS negative subscale score at baseline and percentage change in plasma BDNF level(rho=-0.821, N=7, p=0.023, two-tailed). Conclusion : This preliminary study suggests that rTMS didn't make a significant change in clinical symptoms nor in plasma BDNF level in treatment-resistant schizophrenia. Percentage change in plasma BDNF, however, might be correlated with treatment resistance in schizophrenic patients. This is a pilot study with a small sample size, therefore, a further study with a larger sample size is needed.

Purpose : This study systematically assessed 9 emotion-function programs for schizophrenic individuals that have been implemented over the past 10 years in Korea and abroad, with the objective of providing clinical grounds and data for further programs. Methods : This study identified 2,558 studies from among those registered in the RISS, KISS, EMbase, PubMed and Scopus databases from 2013 to September 2023, using 'schizophrenia' AND 'emotion' AND ('program' OR 'therapy') as keywords. Of the 2,558 studies retrieved from electronic databases, 602 duplicate papers were excluded. After this process, 1,915 papers that did not meet the study's inclusion and exclusion criteria were excluded based on their titles and abstracts. Following a review of the texts of the remaining 41 papers, nine papers were finally selected, excluding 32 papers according to the selection and exclusion criteria. Results : Programs for the emotional function of patients with schizophrenia have continued to be researched. The results of an evaluation on the quality of the selected literature confirmed that a majority of the reviewed items were "uncertain", confirming that there was a risk of bias. The interventions for emotions included art, cognitive-behavioral, and physical programs, of which art programs were frequently applied. Most of the interventions were implemented in hospitals. The dependent variables for evaluating emotions included emotional expression, depression, anxiety, and positive emotions, and among them, emotional expression was used most frequently. Accordingly, the Berkeley expressivity questionnaire was commonly used as an evaluation tool. Conclusion : This study is significant for intending to analyze domestic and overseas programs for the emotions of patients with schizophrenia, thereby proposing the direction for planning and applying interventions in clinical settings. In follow-up studies, it will be necessary to develop a protocol that confirms interventions according to the settings and patient characteristics of programs and expands the scope of literature reviews.

목 적: 정신분열병 환자의 안구추적운동 이상은 유력한 생물학적인 지표이나 유전자적인 원인에 대한 연구가 활발히 진행되지 못하였다. 최근 여러 연구들에서 dystrobrevin binding protein 1(DTNBP1, dysbindin)이 정신분열병의 원인 유전자의 후보 유전자로서 시사되었으나 정신분열병 환자의 안구운동 이상의 원인으로 작용할 것인지에 대한 연구는 거의 없었다. 본 연구의 목적은 DTNBP1 유전자상에 존재한 비교적 인접한 두개의 단염기 다형성들인 SNP A와 P1763이 정신분열병 환자의 안구추적운동 이상의 유전자적인 원인으로 작용할 것인지를 알아보고자 시행되었다. 방 법: 대상군은 217명의 입원한 만성 정신분열병 환자들이며 안구운동(SPEM)을 측정하였고, 신호/잡음의 자연대수 값(Ln S/N ratio)을 구하여 안구운동이 우수한 군과 열등한 군으로 구분하였다. 이후 대상군의 혈액에서 추출한 DNA로부터 DTNBP1 유전자상의 단 염기 다형성들인 SNP A와 P1763를 분석하여 유전자형과 대립인자형을 알아낸 후, 안구운동 이상 유무에 따른 두 군사이의 분포의 차이를 조사하였다. 결 과: 정신분열병 환자들 중 안구운동이 우수한 군의 신호/잡음의 자연대수 값(Ln S/N ratio)의 평균과 표준편차는 $4.39{\pm}0.33$이었고, 안구운동이 열등한 군의 신호/잡음의 자연 대수 값(Ln S/N ratio)의 평균과 표준편차는 $3.17{\pm}0.71$이었다. 두 군 사이에 나이나 성별비율의 차이는 통계적으로 의미가 없었다. SNP A와 P1763의 유전자형과 대립인자형의 분포의 차이는 안구운동 이상 유무에 따라 구분한 두군 사이에 나타나지 않았다. 결 론: DTNBP1 유전자상에 존재한 SNP A와 P1763은 정신분열병 환자의 안구추적운동 이상의 유전자적인 원인으로 작용한다는 증거를 얻지 못하였다.

Purpose: This study was done to uncover the nature of hope experienced by clients with chronic schizophrenia. Method: A phenomenological approach developed by Van Manen was adopted. Data was collected from intensive interviews on 7 clients with chronic schizophrenia and the expatients' biographies and arts. A phenomenological reflection was done in terms of the four life world existentials. Result: Corporeality: Perceiving the body feeling better, proudness of self, accepting their own ill body and transcending the limitation of the body, expressing self, and staying within the boundary of a healthy body were disclosed as the body's experience of hope. Spatiality :A place with safety, freedom, peace, and sharing was the space of hope. Temporality :The essential experience of time with hope was the continuity of moving forward amid cycling and moments being filled up with something. Relationality : Connecting with someone, having someone who is dependable, understandable and exchanging interest and love were identified as the relationships of hope with others. Conclusion: The results of this study show that chronic schizophrenic patients always strive hard to keep hope and they really need someone who can support them.

Objectives:Although polymorphisms of apolipoprotein E have been investigated in many neuropsychiatric disorders, results were controversial and even contradictory. The purpose of this study was to investigate the genotypes of apolipoprotein E in schizophrenia and healthy controls, and to compare them in two groups in terms of distribution of apolipoprotein E genotype and allele. Method:Using polymerase chain reaction and amplified refractory mutation system, apolipoprotein E genotypes were identified in 77 schizophrenics and 115 healthy control persons. Results:The results were as follows 1) When genotypes of apolipoprotein E were classified into ${\varepsilon}2/2$, ${\varepsilon}2/3$, ${\varepsilon}2/4$, ${\varepsilon}3/3$, ${\varepsilon}3/4$, ${\varepsilon}4/4$ according to phenotypes, there were no statistical differences in genotypes between two groups 2) In terms of allele frequency, there were also no statistical differences between two groups Conclusion:These results suggest that genotypes and alleles of apolipoprotein E seem to be unrelated to the pathogenesis of schizophrenia.

Though initial report from Japan showed positive association of schizophrenia with dinucleotide repeat polymorphism in the NT-3 gene, subsequent studies showed mixed results. Therefore we conducted a replication study with Korean schizophrenics and matched controls who share similar ethnic background with Japanese population. The frequency of allele of dinucleotide repeat at 147 base pairs in the NT-3 gene was slightly increased, however, failed to reach statistical significance(${\chi}^2$=1.884, df=1, p<0.170) between the two groups. These findings do not support an association of NT-3 gene polymorphism with schizophrenia in Korean sample.

Objectives: Schizophrenia is a serious disease that influences not only the patients themselves but also their family and the society. In this case, we employed art therapy and Korean traditional medicine for treating a schizophrenia patient.Methods: The patient was diagnosed with schizophrenia, and the main complaints were hallucination, visual hallucination and catatonic behavior. We treated the patient with art therapy and Korean traditional medicine including acupuncture, moxa and herbal medicine. We used the Brief Psychiatric Rating Scale (BPRS) and the Positive and Negative Syndrome Scale (PANSS) for assessment.Results: After treatment, clinical symptoms were improved and the BPRS and PANSS scores were decreased, especially the scores for anxiety, depression and poor rapport.Conclusions: Combined treatment with art therapy and Korean traditional medicine can be effective for treating chronic schizophrenia.

Electroconvulsive therapy(ECT) is one of the most effective treatment modalities for the treatment of depression, mania, schizophrenia, or other neuropsychiatric disorders. But, reportedly ECT also can produce various forms of cardiac arrhythmia. We experienced a case of ECT-induced arrhythmia(PVC) accompanied with chest pain in a schizophrenic patient during the course of plain ECT. We conclude that there is a possible causal relationship between ECT and cardiac arrhythmia(PVC). The mechanisms of cardiac arrhythmia(PVC) due to ECT may be explained by the effects of ECT to vagal and sympathetic nervous systems. from this case report, We suggest that careful cardiac monitoring before, during, and after ECT with appropriate anesthetic preparation to a patient may enable to minimize the cardiovascular side effects of ECT in the patients with neuropsychiatric disorders.

An association study with Korean schizophrenic patients(N=84) and normal controls(N=87) was performed to find the relationship between catechol-O-methyltransferase(COMT) gene polymorphism and schizophrenia using polymerase chain reaction-restriction fragment length polymorphism. When we compared the allele and genotype frequencies of Bgl I COMT gene polymorphism in schizophrenics and normal controls, there was no significant difference between two groups. Our results do not support an association between the Bgl I polymorphism of COMT gene and schizophrenia.
