2.pharmacogenomics and Schizophrenia.
Journal of the Korean Society of Biological Psychiatry 2001;8(2):208-219
The pharmacotherapy of schizophrenia exhibit wide inter-individual variabilities in clinical efficacy and adverse effects. Recently. human genetic diversity has been known as one of the essential factors to the variation in human drug response. This suggests that drug therapy should be tailored to the genetic characteristics of the individual. Pharmacogenetics is the field of investigation that attempts to elucidate genetic basis of an individual's responses to pharmacotherapy, considering drug effects divided into two categories as pharmacokinetics and pharmacodynamics. The emerging field of pharmacogenomics. which focuses on genetic determinants of drug response at the level of the entire human genome, is important for development and prescription of safer and more effective individually tailored drugs and will aid in understanding how genetics influence drug response. In schizophrenia, pharmacogenetic studies have shown the role of genetic variants of the cytochrome P450 enzymes such as CYP2D6, CYP2C19, and CYP2A1 in the metabolism of antipsychotic drugs. At the level of drug targets, variants of the dopamine D_(2), D_(3) and D_(4), and 5-HT_(2A) and 5-HT(2C) receptors have been examined. The pharmacogenetic studies in schizophrenia presently shows controversial findings which may be related to the multiple involvement of genes with relatively small effects and to the lack of standardized phenotypes. For further development in the pharmacogenomics of schizophrenia, there would be required the extensive outcome measures and definitious, and the powerful new tools of genomics, proteomics and so on.

Korean Journal of Preventive Medicine 1977;10(1):3-15
In order to find out health problems among inhabitants in slum areas in Kwanak-Ku, Seoul, a series of health survey was conducted upon 510 households by interview from March to December, 1976. The results obtained were as follows: 1. Employments of householders were unstable; Out of 508 householders, 164(32.3%) were unemployed and 184(36.2%) were daily or temporary employees. 2. Average number of households per house was 2.0 and average area of residential room per person was 4.0m2. 3. 476(93.3%) out of 510 households were supplied with tap water and rest of them made use of ground water as a source of drinking water. 4. Only 279(18.3%) out of 1527 live births were delivered at medical facilities, 496(32.7%) were at home attended by doctors or midwives and 358(25.1%) took prenatal care. The above findings were worse in urban slum area than in other urban area of relatively high economic level, but were better than in rural area of less medical facilities. 5. Initiation of treatment were delayed until their illnesses were advanced in most of the households, 472(92.5%) out 510. In the early stage of the illness, 131(25.6%) of the households sought physicians in their clinics or general hospitals and 250(40.9%) visited chemists, to buy drugs at first hand. Frequency of visits to physician increased to 52.8% as the disease aggravated in later stages. 6. Cost of medical expenditure per household amounted to 815 won, and was paid to, in the order of chemists, physicians, chinese herb stores, chinese herb doctors. 7. Concerning the health knowledge of the inhabitants, 273(53.9%) out of 506 respondents were aware of the infectivity of pulmonary tuberculosis, and 68(13.4%) of them checked regularly their chest findings by X-ray at least once every two years. 8. As for the family planning, although 448(87.3%) out of 510 respondents were in favor of it, 213(41.8%) of them were actually practicing contraception. 9. About 40.6% (125 respondents) of them obtained information and knowledge concerning contraception through personal contact with family planning workers. 10. Nutritional status of housewives was generally poor: 49(38.3%) out of 128 housewives were found to be anemic and average serum protein level was 7.5+/-0.82 g/dl.

4.PSYCHOLOGICAL ASPECT OF PATIENT SATISFACTION AND ACCEPTANCE OF COMPLETE DENTURES.
The Journal of Korean Academy of Prosthodontics 1999;37(4):494-505
In spite of the progress in techniques and materials of the prosthodontic rehabilitation of patients with complete edentulous arches, prosthodontists still face patients' complaints about dissatisfaction and discomfort from their dentures. In the past several decades, prosthodontists tried to find the factors that influence the patient's satisfaction with dentures. However the results are contraversial especially with the psychological factor. In this study using patient denture satisfaction questionnaire' and Hopkins Symptom Checklist, we tried to find the correlation between the patient's denture satisfaction and the patient's psychological aspects. 23 complete edentulous patients who have visited the Department of Prosthodontics, Yonsei University Dental Hospital from September 1998 to June 1999 for complete denture treatment were asked to complete the questionnaires 4 to 6 weeks after the upper and lower complete delivery. After the measurement of validity of the questionnaires, correlations between the patient's general satisfaction with their new upper and lower complete dentures and the other satisfaction questions including the satisfactions with esthetics, retention, mastication, speech, comfort and other peoples's opinion and between the patient's general satisfaction with their new upper and lower complete dentures and the 5 symptoms of Hopkins Symptoms Checklist including somatic, obsessivecompulsive, interpersonal sensitivity, depression and anxiety were analyzed. Among the several satisfaction questionnaire items, comfort with the lower denture showed highest relation to the patient's general satisfaction with dentures. However, only the anxiety scale of Hopkins Symptom Checklist among the other symptom scales was related to the patient's general satisfaction with dentures. The two questionaires used in this study turned out to be valid means of analyzing patient's denture satisfaction and psychological status before and after the complete denture treatment.

A case of a clinical syndrome of selective hereditary complete IgA deficiency with partial T-lymphocyte inactivation is reported. A 14 year old boy was admitted with chjef complaint of persistent wide shallow ulcerated non-vesicular patches on the skin folds of whole body, chronic upper respiatory infections and gastointestinal upsets. General appearance showed us as if the undemourished or malabsorption status had been accompanied. The duration of illness was about 10 years under the incorrect or mistaken diagnosis and skin lesions have incompletely responded to the treatment. Peripheral T-lymphocyte determination was carried out by the method of Wybran to be tumed out active T-cell 14%, total T-cell 48%. Tuberculin test showed negative with 5 TU. Immunoglobulin values were respectively as follows: IgG 325 mg%, IgM 60 mg%, and IgA trace. And we diagnosed this case as selective IgA defiency with partial T-lymphocyte inactivation. We started the immunochemotherapy with tuberculo-protein complex, Tubercin-3 and antibictics for 2 months. After 2 months with above regimen. the skin lesions were markedly improved. T-cell count also retumed to the normal limit(active 35%, total 59%) and levels of TgG and IgM raised(IgG 617.5 mg%, IgM 75mg%), but IgA still showed trace amount, Tuberculin test tumed out positive.

BACKGROUND AND OBJECTIVES: N-cadherin is known to be expressed in neuroectodermal tissue such as central nervous system and various mesodermal origin tissues such as kidney and heart. We investigated N-cadherin expression in the endocardial cushion in developing rat heart by immunohistochemical method. MATERIALS AND METHOD: Fetal rat hearts at the 11th, 13th, 15th, 17th, and 19th day of gestation and the 1st day neonatal rat heart were used. Hematoxylin and eosin stain was performed for normal cardiogenesis, and immunohistochemistry was performed for the expression of N-cadherin in interventricular septum(IVS) during cardiogenesis in rat. RESULTS: Ventricular wall and membranous part of the IVS showed positive reaction with anti-N-cadherin at the 11th day of gestation. Membranous part of IVS was begun to show tracely positive reaction at the 15th day of gestation, and thereafter the immunoreactivity was increased with maturation. At the 17th day of gestation mesenchymal cells in membranous muscular part of the IVS showed positive reaction. The similar immunoreactivity of membranous and muscular parts of IVS were shown at the 19th day of gestation. CONCLUSION: As the immunoreaction of mesenchymal cells in the membraneous part of IVS to anti-N-cadherin was increased with time, it is suggested that mesenchymal cells in membranous part of IVS were differentiated into the cardiomyocytes.
