  • Forty cases of coronary artery bypass grafting treated at the Department of Thoracic and Cardiovascular Surgery, SNUH, Korea were compared with forty cases of the procedure treated at University of Alberta Hospital, Canada, in terms of pathoanatomy. That showed no difference in sex ratio between Korean and Caucasian the average ages, however, were 50.4 years and 60.9 years respectively [p< 0.005]. The leading cause of angina at presentation was unstable angina in Korean, but it was post-infarction angina in Caucasian instead. The incidences of single-vessel disease and double-vessel disease were similar in both countries, but the incidence of so-called triple-vessel disease was higher in Caucasian while left main coronary artery disease was more prevalent in Korean [0.01< P, 0.005]. < The internal diameters of surgically available coronary artery branches had similar characteristics and no significant statistical differences were found between them. The predilection sites of stenoses were proximal left anterior descending artery, left main coronary artery, proximal left circumflex artery and proximal right coronary artery decreasing in incidence respectively, in Korean. The myocardial perfusion score were 6.80 in single-vessel disease, 7.56 in double-vessel disease, 11.27 in triple-vessel disease and 9.77 in left main disease respectively, in Korean.

  • Background: Korean regression models for spirometric reference values are different from those of Americans. Using spirometry results of Korean adults, goodness-of-fits of the Korean and the USA Caucasian regression models for forced vital capacity (FVC) and forced expiratory volume in one second ($FEV_1$) were compared. Methods: The number of study participants was 2,360 (1,124 males and 1,236 females). Spirometry was performed under the guidelines of the American Thoracic Society and the European Respiratory Society. After excluding unsuitable participants, spirometric data for 729 individuals (105 males and 624 females) was included in the statistical analysis. The estimated FVC and $FEV_1$ values were compared with those measured. Goodness-of-fits for Korean and USA Caucasian models were compared using an F-test. Results: In males, the expected values of FVC and $FEV_1$ using the Korean model were 12.5% and 5.7% greater than those measured, respectively. The corresponding values for the USA Caucasian model were 3.5% and 0.6%. In females, the difference in FVC and $FEV_1$ were 13.5% and 7.7% for the Korean model, and 6.3% and 0.4% for the USA model, respectively. Goodness-of-fit for the Korean model regarding FVC was not good to the study population, but the Korean regression model for $FEV_1$, and the USA Caucasian models for FVC and $FEV_1$ showed good fits to the measured data. Conclusion: These results suggest that the USA Caucasian model correlates better to the measured data than the Korean model. Using reference values derived from the Korean model can lead to an overestimation regarding the prevalence of abnormal lung function.

  • Purpose: This study was designed to investigate the fitness of adjustable dental impression trays on the Caucasian and African American. Material and methods: The size and shape of these trays were designed from the results of the dental arch size of Korean adults. Tray samples were made by CAD-CAM working. Sixty Caucasian (male:30, female:30) and sixty African American (male:30, female:30) were selected for taking irreversible hydrocolloid impression using these trays. The author measured the width and length of impression material on the several measuring points. Results: 1. Uniform impression material width was achieved by controling the width of the tray using stops and beveled guides. 2. In the maxillary tray on the Caucasian, the impression material thickness was measured to be rather great showing thickness of the midpalatal part 13.0 mm. 3. In the maxillary tray on the African American, the impression material thickness was measured to be rather great showing thickness of the midpalatal part 12.0 mm, posterior palatal part 11.0 mm and the labial frenum width was 11.0 mm. 4. In the maxillary tray on the African American, the impression material width of posterior border (0.8 mm) was measured to be small. 5. In the mandibular tray on the Caucasian, the impression material width was measured (2.7-6.7 mm) and posterior border width (2.1 mm) was measured small. The impression material length was measured (2.8-6.7 mm). 6. In the mandibular tray on the African American, the impression material width was measured to be rather great showing width of the labial frenum 9.2 mm and the width of posterior border was measured too small (0.3 mm). Conclusion: This adjustable dental tray shows good accuracy to Korean because it was designed by the analysis of the dental arch size of Korean adult model. With this result, it can be applied to Caucasian and African American, we can take more easy and accurate dental impressions.

  • Background: Sasang Constitutional Medicine (SCM) is a component of Korean traditional medicine that classifies humans into four categories, according to their constitution (Taeyangin, Taeumin, Soyangin and Soeumin). We are unaware of previous assessments of SCM in non-Asian race groups. Objectives: To quantify body composition components in three race groups and to determine whether SCM has an independent effect on body composition components. Design: A cross-sectional evaluation of 76 adults (28 Caucasian, 21 African-American, 27 Asian). Body composition was estimated using dual energy x-ray absorptiometry. Results: SCM component had a significant effect on weight, fat, and lean mass regardless of race group (p <0.001).

  • This study explores the influence of health behaviors and individual attributes on adolescent overweight and obesity using data from Wave II (Add Health). Structural equation model/ path analysis using maximum likelihood estimation was utilized to analyze the relationships of health behaviors and attributes with obesity. Results of the model reveal that the causal paths (adolescents' attributes and health behaviors) for overweight and obesity were different for African American and Caucasian adolescents. Generally, African Americans were more susceptible to overweight and obesity than Caucasians. Although increasing levels of vigorous physical activities lowers the risk for obesity among African American and Caucasian adolescents alike, low family SES and being sedentary were associated with overweight and obesity among Caucasians. No significant associations were found among African Americans. Increased hours of sleep at night relate positively with obesity among African Americans. These findings suggest important elements in the consideration of race in developing effective intervention and prevention approaches for curbing the obesity epidemic among U.S. adolescents.

  • Data from the National Longitudinal Study of Youth (NLSY) were used to examine factors related to adolescent behavior problems, smoking, and delinquency. This study focuses particularly on the factors in an adolescent s immediate environment such as family, school, peers, and neighborhood (i.e. the microsystems) for the identification, prevention, and early intervention of adolescent behavior problems, smoking, and delinquent behavior. Both African American and Caucasian American adolescents between the ages of 13 and 17 for whom data were available in the NLSY were included in this study (N=788). Results indicate that delinquent peer pressure and negative attitudes toward school are important determinants of behavior problems, smoking, and delinquency of American adolescents. Differences between African American and Caucasian American adolescents are highlighted.

  • Single nucleotide polymorphisms (SNPs) in the promoter region of the IL-1B (interleukin-1) gene have been implicated in a variety of diseases that have an inflammatory component. However, there has been significant heterogeneity among study results, especially between Caucasian and Asian populations. Recently, it has been reported that SNPs in the IL-1B gene affect transcription, according to haplotype context, and genetic association studies may be more informative if functional SNP haplotypes of population are analyzed. Therefore, we estimated the distribution of IL-1B promoter haplotypes in 433 Koreans using the three major functional IL-1B promoter SNPs (IL-1B -1464, -511, and -31) and compared the results with those in Caucasians. The difference in IL-1B promoter haplotype frequency between Korean and Caucasian populations was statistically significant. The potentially more inflammatory haplotypes had higher frequencies in Koreans when compared with Caucasians. These Korean haplotype data will be useful for future association studies between IL-1B SNPs and disease risk.

  • Leiden), no mutation was detected in either group. Allele frequencies of A2379G and G2391 A mutations were not significantly different between CAD patients and controls. Non-Caucasian populations have a considerably lower factor Ⅴ Leiden allele frequency than Caucasian populations. Thus, it may be due to differences in the genetic background as well as environmental factors.
