Objectives: A positive association between serum albumin levels and metabolic syndrome has been reported in observation studies, but it has not been established in the Korean population. The purpose of this study was to evaluate the association between serum albumin levels and the presence of metabolic syndrome among a sample of apparently healthy Korean adults. Methods: This cross-sectional study analyzed data of 3189 community-dwelling people (1189 men and 2000 women) who were aged 40 to 87 years and were living in a rural area in Korea. Serum albumin levels were classified into quartile groups for each sex. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III guidelines with an adjusted waist circumference cut-off value ${\geq}90\;cm$ for men and${\geq}85\;cm$ for women). An independent association between serum albumin levels and metabolic syndrome was assessed by multiple logistic regression analysis. Results: Higher serum albumin levels were associated with increased prevalence of metabolic syndrome. The odds ratio (95% confidence interval) of the prevalence of metabolic syndrome for the highest versus the lowest serum albumin quartiles was 2.81 (1.91 to 4.14) in men and 1.96 (1.52 to 2.52) in women, after adjusting for age, smoking status, alcohol consumption, and physical activity. When each metabolic abnormality was analyzed separately, higher serum albumin levels were significantly associated with hypertriglyceridemia and hyperglycemia in both sexes, and with abdominal obesity in men. Conclusions: These results suggest that higher serum albumin levels are positively associated with an increased risk of metabolic syndrome in Korean adults.

PURPOSE. We aimed to identify a more esthetic width-to-length ratio by analyzing maxillary central incisor of Korean adult population. Information regarding tooth ratio in the Korean population may be useful to clinicians when restoring anterior teeth. MATERIALS AND METHODS. A total of 40 men and 40 women were included in this study. The NON-MEDIA group included 40 non-celebrities, who were healthy and 25 to 39 years old, with normal dentofacial appearance. The MEDIA group consisted of 40 celebrities selected only on the basis of their soft-tissue facial appearance. The facial photographs of 40 celebrities were collected from the Internet websites. The width and length of the maxillary central incisor were measured using Adobe $Photoshop^{(R)}$ 7.0, a software for analysis, measurement and edition of photographs. Data were analyzed statistically using the Independent t-test at 5% statistical significance level. RESULTS. The mean ratio for the MEDIA group was 0.77, whereas that of the NON-MEDIA group was 0.88. The difference between the two groups was statistically significant. No significant gender differences were found in the width-to-length ratio in MEDIA group. In NON-MEDIA group, however, there were significant differences between female and male. CONCLUSION. After analyzing maxillary anterior teeth of Korean adults, our results were in accordance with the general Western standards of esthetics. A dentist restoring the natural look and beauty of teeth will have to consider those standards.

Objectives : The alcohol dependence in elderly people has been prevalent because of increase in geriatric population. However, it is difficult to find out alcohol dependence in the aged, because they have less specific clinical features as compared with adult alcoholics. The aims of this study were to screen alcohol dependence among elderly Koreans and to know the clinical characteristics of Korean delerly alcoholics. Methods : The questionnaires translated into Korean such as Michigan Alcoholism Screening Test(MAST-K), the Brief MAST and the MAST-Geriatirc Version (MAST-KG) were used to screen alcohol dependence in the elderly alcoholic inpatients aged over 60(N=43), adult alcoholic inpatients within 20-59 Yrs of age(N=60), which were compared with age matched normal healthy aged(N=18) or adult controls(N=45). The demographic data such as sex, age, education, occupation, socioeconomic status, marital status, numbers of children, dwelling and religion as well as alcohol history such as duration of alcohol drinking, onset age, family history, impulsivity, somatic illness and motivation were also obtained to identify characteristic features of Korean aged alcoholics by structured interviews. Results : 1) The aged alcoholics had the charateristic features of more in males, lower age, low education levels, more in blue-collar workers, lower socioeconomic class, more in single, few babies, more living alone, having no religion without statistical significance. 2) The onset age of alcohol dependence was significantly higher in the aged alcoholics($45.3{\pm}13.6Yrs$) than in the adult alcoholics($27.7{\pm}8.7Yrs$)(p<0.0001). The duration of problematic alcohol drinking was significantly longer in the aged alcoholics($22.0{\pm}15.1Yrs$) than in adult alcoholics($14.2{\pm}8.4Yrs$)(p<0.01). Otherwise, there were no significant difference between aged and adult alcoholics in the family history, imulsivity, somatic illness and motivation. 3) The mean score of the MAST-K was significantly higher in the aged alcoholics($20.6{\pm}5.4$) than in the normal aged($6.7{\pm}4.4$)(p<0.0001), which was significantly lower than in the adult alcoholics($26.2{\pm}8.0$) and in normal adult controls($9.5{\pm}3.2$)(p<0.05). The mean score of the Brief MAST was significantly lower in the aged alcoholics($9.3{\pm}3.5$) than in the adult alcoholics($14.5{\pm}6.6$)(p<0.0001). The mean score of the MAST-KG was significantly higher in the aged alcoholics($10.6{\pm}3.5$) than in the normal aged($4.8{\pm}4.3$)(p<0.0001). The former was significantly lower than in the adult alcoholics($12.9{\pm}4.3$)(p<0.005), and the mean score was $4.5{\pm}2.8$ in normal adult controls. 4) The items which showed statistically significant differences between aged alcoholics and normal aged controls could be found in 10 items of the MAST-K(items 2, 3, 4, 5, 11, 14, 17, 21, 22 and 23), 2 items of the Brief MAST(items 2 and 9), and 7 items of the MAST-KG(items 6, 13, 18, 19, 22, 23 and 24)(p<0.01). Conclusions : The scores of the MAST-K, the Brief MAST and the MAST-KG were significantly lower in the aged alcoholics than those in the adult alcoholics (p<0.05). The statistically significant differences between aged alcoholics and normal aged controls could be found in 10 items of the MAST-K, 2 items of the Brief MAST and 7 items of the MAST-KG. Therefore, a briefer rating scales around 10 items are needed to screen alcohol dependence among Korean elderly people.

Fermented milks have been recognized as healthy foods since ancient times, but those using intestinal bacteria such as Bifidobacterium and lactic acid bacteria (LAB) are even more valuable from the standpoint of view of maintaining health. They have also now come to be recognized as important in the field of preventive medicine. Although advances in the medical sciences in the last 50 years have significantly increased the human lift span, an unfortunate fact is that many of us are now living long enough to experience chronic disorders such as coronary heart disease, hypertension, osteoporosis, diabetes and cancer. In recent years there has been renewed interest in health promotion and disease prevention by incorporating probiotic bacteria into foods to counteract harmful bacteria in the intestinal tract. Therefore, there are now a wide variety of commercial products containing prospective probiotics that claim health-promoting effects, such reductions in large botvel carcinogens and mutagens, antitumor properties, cholesterol-lowering effects, increased lactose digestion, relief from con-stipation, stimulation of immunocomponent cells and enhancement of phagocytosis. Two well-known representative probiotic is LAB and Bifidobaclerium. Traditional probiotic dairy strains of LAB which have been designated as GRAS (Generally Recognized As Safe) bacteria have a long history of safe use and most strains are considered comestible microorganisms with no pathogenic potential. Accordingly, there is considerable interest in extending the range of foods containing probiotic organisms from dairy foods to infant formulas, baby foods, and pharmaceuticals. In addition, the ingestion of probiotics, prebiotics, and symbiotic as wll as combinations of pro- and prebiotics has recently aroused renewed interest as enhancing the beneficial relationship between the host and intestinal microflora in both healthy and diseased indivisuals. Non-communicable chronic diseases such as cancer, cerebral hemorrhage, is chemic heart disease, and diabetes mellitus has recently been recognized as adult diseases in Japan as well as other countries. and are considered to be inevitably associated with aging. These diseases occur as a result of individual life styles. The Japanes Government. Ministry of Health, Labor and Welfare has proposed substituting the term 'adult diseases' with 'lifestyle-related diseases'. It has emphasized the importance of prevention rather than treatment. since the well-known increase in the elderly population in Japan is predicted to result in a variety of socioeconomic problems. n this lecture on the Present status of fermented milk products in Japan, I will report a strategy for the development of fermented milk products in Japan from the standpoint of view of research in Japan on LAB and Bifidobacteria. They could play an important role in preserving human health by controlling intestinal microflora capable of producing toxic effects on the host.

지난 20 여년간 미주 한인의 수는 급속도로 증가하였다. 하지만 이들의 건강에 관한 연구는 거의 이루어지지 않았다. 본 연구는 기대여명(期待餘命), 연령별 사망률, 그리고 사망의 주요원인 등을 통한 본국 거주 한국인과 미주 한인의 건강 수준 비교를 그 목적으로 한다. 분석결과 전반적으로 미주 한인이 같은 연령의 한국인에 비해 기대여명은 더 높고, 연령별 사망률은 더 낮게 나타났다. 사망의 주요 원인에 관한 분석 결과, 미주 한인에게 있어서 신생물 (Neoplasms)로 인한 사망이 빈번하게 발견되었으나 소화기계 질환 (Diseases of the digestive system), 특히 간질환으로 인한 사망률은 동일연령의 본국 거주 한국인에 비해 크게 낮은 것으로 나타났다. 두 인구 집단간 큰 차이를 보이는 신생물과 소화기계 질환에 대해 인구 사회 경제적 요소들을 통제하여 회귀 분석을 실시한 결과 신생물로 인한 사망 비율의 차이는 변함이 없었다. 결론적으로 미주 한인이 본국 거주 한국인에 비해 상대적으로 양호한 건강상태를 유지하고 있다고 볼 수 있고, 이는 미주 한인의 교육수준이 상대적으로 높고, 이민 후 보다 건강한 생활습관을 습득하기 때문이라고 여겨진다. 그러나 미주 한인의 경우 이질적인 문화와 언어 사용에 의한 정신적 스트레스와 소수민족이기 때문에 보건정책의 혜택에서 쉽게 소외된다는 사실 등을 고려할 때 본 연구 결과는 보다 지속적고 심도있는 연구의 필요성을 시사한다.

Objective : Adipose tissue is derived from the embryonic mesoderm and contains a heterogenous stromal cell population. Authors have tried to verify the characteristics of stem cell of adipose derived stromal cells (ADSCs) and to investigate immunohistochemical findings after transplantation of ADSC into rat brain to evaluate survival, migration and differentiation of transplanted stromal cells. Methods : First ADSCs were isolated from human adipose tissue and induced adipose, osseous and neuronal differentiation under appropriate culture condition in vitro and examined phenotypes profile of human ADSCs in undifferentiated states using flow cytometry and immunohistochemical study. Human ADSCs were transplanted into the healthy rat brain to investigate survival, migration and differentiation after 4 weeks. Results : From human adipose tissue, adipose stem cells were harvested and subcultured for several times. The cultured ADSCs were differentiated into adipocytes, osteoctye and neuron-like cell under conditioned media. Flow cytometric analysis of undifferentiated ADSCs revealed that ADSCs were positive for CD29, CD44 and negative for CD34, CD45, CD117 and HLA-DR. Transplanted human ADSCs were found mainly in cortex adjacent to injection site and migrated from injection site at a distance of at least 1 mm along the cortex and corpus callosum. A few transplanted cells have differentiated into neuron and astrocyte. Conclusion : ADSCs were differentiated into multilineage cell lines through transdifferentiation. ADSCs were survived and migrated in xenograft without immunosuppression. Based on this data, ADSCs may be potential source of stem cells for many human disease including neurologic disorder.

Background: The aim of this study was to compare the effects of squat training on an unstable support surface with different knee flexion angles on the balance ability of normal adults balance ability. Methods: 41 university students in their 20s attending N University in Cheonan, Chungcheongnam-do were divided into a 45-degree knee-bending squat training group and a 90-degree knee-bending squat training group. The groups trained on an unstable support surface 20 minutes per day, 3 times a week, for a total of 4 weeks. Results: Changes in static balance ability were not significant within and between the groups for both the sway distance and sway area in the eyes open and eyes closed states (p<.05). The changes in dynamic balance ability were significant in the forward, leftward, and rightward angles in both groups at the limit of stability (p<.05), but not significant in the backward angle (p>.05), and the comparison between groups was not significant (p>.05). Conclusion: No significant difference between static balance-related variables within and between the groups was found. Significant changes in dynamic balance-related variables within the groups were found but not between the groups. Therefore, in future studies, it is considered necessary to study various ages and differentiated intervention periods, such as young adults and the population of elderly people, with sufficient intervention periods to affect balance ability.
