BACKGROUND: Dopamine receptors are strong candidates for involvement in schizophrenia and are target of a wide variety of antipsychotics. Dopamine D5 receptor(DRD5) gene polymorphisms may be associated with various treatment response. The purpose of our study was define to what significance can be held as a predictor of treatment response in this polymorphism. METHOD: The total number of 116 Korean chronic schizophrenic patients was assessed after 48 weeks treatment. The Positive and Negative Syndrome Scale(PANSS) was rated for the clinical response to various antipsychotics. With the use of polymerase chain reaction amplification, we assessed this dopamine D5 receptor polymorphism in schizophrenic patients who had been treated with antipsychotics, and related genotype with treatment response, to test the hypothesis that DRD5 polymorphism may lead to varying resonse to antipsychotic. RESULT: DRD5 polymorphism was not associated with treatment response to a variety of antipsychotics in chronic schizophrenic patients. CONCLUSION: Genetic variation of D5 receptors do not predict treatment response to antispychotics.

BACKGROUND: Dopamine receptors have been regarded as a strong candidate involved in etiology of schizophrenia and a target for various antipsychotic drugs. The purpose of our study was to investigate whether dopamine D1 receptor(DRD1) gene polymorphisms would predict the treatment response to antipsychotics in schizophrenia. METHOD: One hundred thirty-four schizophrenic patients, who met DSM-IV criteria for schizophrenia were entered into a 48-week study. The psychopathology of the patients was assessed at baseline, 12th, 24th, 48th weeks of treatment by PANSS. Responders were defined by a 20% of the reduction in total PAnSS score at end point. The genomic DNA fragment corresponding to nucleotides of dopamine D1 receptor gene was amplified by polymerase chain reaction(PCR). RESULT: Neither allelic frequencies nor genotypes for dopamine D1 receptor differed significantly between responders and non-responders. Also, there was no difference of changes of PANSS scores among three genotype groups of the dopamine D1 receptor. CONCLUSION: Allelic variation in the dopamine D1 gene is not associated with individual differences in antipsychotic response.

OBJECTIVES: The purpose of this study was to examine the effect of the vocational rehabilitation program on the quality of life of the chronic schizophrenics, and to evaluate how chronic schizophrenics felt about their lives. METHOD: The subjects were 39 chronic schizophrenics who had participated in the vocational rehabilitation program(participant group) and now lived in the community. The control group were 43 chronic schizophrenics who were outpatients without vocational rehabilitation(non-participant group). The scale for quality of life was divided into two subscales, i.e., the objective and the subjective areas. The subscales are composed of living situation, family situations, interpersonal relations, work, health, finances, leisure activities, autonomy, and self-esteem. RESULTS: 1) In the demographic characteristics such as age, sex, duration of illness, and duration of education, two groups were not different significantly. However, dosage of antipsychotics were lower in participant group than non-participant group. 2) In the objective quality of life subscale, the scores of living situation, interpersonal relations, work, health, economic state, and leisures were higher in participant group than non-participant group. But, family relations score were lower in participant group than in non-participant group. autonomy were not different between two groups. 3) In the subjective quality of life subscale, the score of living situation, family relations, interpersonal relations, work, health, economic states, leisure activities, and autonomy were all higher in participant group than in non-partcipant group. 4)Self-esteem was significantly higher in participant group than in non-participant group. CONCLUSION: The results from this study suggest that the objective and subjective quality of life of participant group in the vocational rehabilitation program were higher than those of non-participant group. The vocational rehabilitation program of Yong-In Mental Hospital seems to have been effective for the chronic schizophrenics. And the psychosocial rehabilitation program, vocational rehabilitation program, and family education program should be developed more and implemented in the community.

A parallel group double-blind comparative trial was conducted to study the efficacy and safety of risperidone compared with haloperidol. After a one-week wash-out, 35 chronic schizophrenic patients (17 males, 18 females) were randomly assigned to one of two groups for eight weeks of double-blind treatment. The patients' psychopathology was assessed by means of the Positive and Negative Syndrome Scale for Schizophrenia (PANSS) and the Clinical Global Impression (CGI). Safety assessments included the Extrapyramidal Symptom Rating Scale (ESRS), the UKU Side Effect Rating Scale, vital signs, body weight, ECG and laboratory screening. Thirty-two patients completed the trial: there were 3 dropouts in the risperidone group. The results on the PANSS and CGI indicate that the mean changes from baseline on the total PANSS score and on the total BPRS score were comparable in both treatment groups. The number of patients where a clinical improvement at least 20% reduction in baseline score was also similar in both treatment groups. Risperidone caused less extrapyramidal symptoms and less side effects in UKU scale than haloperidol. No significant ECG changes were induced, no relevant changes in blood pressure or clinical laboratory parameters were observed. This study has demonstrated that the combined serotonin 5-HT2 and dopamine-D2 antagonist risperidone is an antipsychotic as potent as haloperidol. Risperidone causes less extrapyramidal symptoms, and is better tolerated than haloperidol.

BACKGROUND: Ventrlcular tachyarrhythmias are major cause of sudden cardiac death in patients after myocardial infarction and their accurate detection seems to be important in prevention of sudden cardiac death. Clinical findings, treasmill test, holter monitoring and coronary angiography have been used to search for high risk group in sudden cardiac death. Recently electrographysiologic stimulation has been to this, but it is not practical, because of high cost and invasiveness. Signal averaged electrocardiogram(SAECG) may be helpful in prediction of high risk group in sudden cardiac death. So we try to know the values of SAECG in Korean patients without heart disease. RESULTS: 1) The mean value and standard deviation of Time domain analysis is as follows ; fQRS : 106.8+/-12.3ms, RMS : 36.2+/-21.5(micro)V, LAS : 27.2+/-8.1ms. 2) The mean value and standard deviation of Spectral turbulence analysis is a follows ; LSCR : 58.6+/-3.9, ISCM : 95.2+/-0.8, ISCSD : 71.8+/-15.7, SE : 6.9+/-1.8. CONCLUSION: There was no significant difference between male and female. Time domain analysis shows significant differences among each hour but spectral turbulence analysis did not. Spectral turbulence analysis shows high specificity.

BACKGROUND: The interpretation of electrocardiographic change in treadmill exercise test is difficult when the test is performed in patients with abnormal resting electrocardiography. In patients with primary nagative T wave, normalization of primary negative T wave(pseudonormalization)is not uncommon finding during treadmill exercise test. The mechanism of pseudonormalization is uncertain and the interpretation is difficult. Thus this study was performed to evaluate the diagnostic significance of pseudonormalization during treadmill exercise test. METHODS: 200 cases who showed primary negative T wave at rest were included in this study. The results were classified as positive, borderline positive, borderline negative, negative, non-diagnostic and pseudonormalization. RESULTS: Pseudonormalization during treadmill exercise test was oberved in 78(39%) of the 200 cases who had primary negative T wave at rest. Coronary angiography and left ventriculography were performed in 13(mean age 56+/-7 year, male vs. female 1:2.25) of 78 cases who showed pseudonormalization during exercise. They had no history of acute myocardial infarction and no abnormalities such as abnormal Q wave, left ventricular hypertrophy,bundle branch block,right ventricular hypertrophy and QRS widening above 0.1ms in resting electrocardiography. There were significant stenosis in only 3 cases; 2 cases in left anterior descending coronary artery and 1 case in right coronary artery. CONCLUSION: In treadmill exercise tests, pseudonormalization appears as non-specific finding for the diagnosis of ischemic heart disease becuase it is observed in either patients with or without coronary artery stenosis.

We have randomly selected 1,200 psychiatric inpatients from the whole psychiatic inpatients population in Korea, and analyzed their length of stay far the purpose of contributing to community mental health practice in Korea. The results were as follows: 1) The half of total samples' length of stay were within 761 days, and 75% of them wihin 2, 613 days. 2) As for length of stay P50, asylums showed the length of stay within 2,303 days for the half of selected samples: 483 days for private mental hospitals and they showed very long-term hospitalization compared to university hospital(20 days), general hospitals(41 days), private psychiatric clinics(45 days) and national mental hospitals(83 days). 3) As for length of stay according to age distributions, the older the patients were, length of stay showed the longer. 4) Among the length of stay at P50 according to diagnoses, mental retarded patients were the longest hospitalization group in private hospitals(707 days) and small psychitric inpatient units(below 30 beds, 166 days). But schizophrenics were the longest hospitalization group(2, 560 days) at asylums. 5) Length of stay at P50 according to medical security had great differences between the medical aid group and medical insurance group, especially in asylum(2,461 days vs. 1,715 days) and mental hospitals(615 days vs. 271 days). From the above results, the authors propose that for diminishing the length of stay policy, Korean mental health system should develop new rehabilitation programs for acute symptom relieved schizophrenic patients. In addition, the treatment for the younger mentally-ill patients should be more active and intensive.
