CD44, also known as the Hermes antigen, H-CAM, pgp-1 antigen, and extracellular matrix receptor ECM-III, is a widely distributed integral membrane protein that exists in a variety of forms with different molecular sizes ranging from 85kd to 160kd. A number of evidence implicates CD44 as a cell adhesion molecule with a possible role in tumor progression. To evaluate the possible roles of CD44 in the metastatic process of gastric carcinoma to the regional lymph nodes, we applicated immunohistochemical stains with the CD44H and CD44v6 primary antibodies onto the 2 groups of gastric adenocarcinomas. Each group was comprised of 22 primary tumors extending to the subserosa, and one group showed nodal metastasis, while the other group did not. Seventeen primary tumors (77%) out of the 22 cases with the nodal metastasis demonstrated positivity to the CD44v6, while only 9 primary tumors (41%) out of the 22 cases without nodal metastasis did. However CD44H immunoreactivity was demonstrated in tumor cells of all cases (100%) of both groups as well as in the normal cell components. These results suggest that CD44H form is not related to the metastasis to the regional lymph nodes of gastric carcinoma. However, the expression of CD44v6 seems to play a certain role in the metastatic process of the gastric carcinoma.

BACKGROUND AND OBJECTIVES: The recurrence rate of patients with Graves' disease (GD) is estimated to be 50-55% after withdrawal of antithyroid drug therapy, and relapse is frequent in the first year after discontinuing the medication. Follow-up examination of these patients frequently reveals laboratory findings consistent with subclinical thyrotoxicosis in the first year after stopping the antithyroid agents. We investigated the risk of recurrence of GD among patients with resurfacing subclinical thyrotoxicosis state after remission of initial GD with antithyroid treatments. MATERIALS AND METHODS: We reviewed the patients diagnosed with GD who visited the Department of Endocrinology at two tertiary medical centers: Wonju Severance Christian Hospital and Gangneung Asan Hospital. We enrolled patients whose GD was completely treated after initial treatment with antithyroid agents who then developed subclinical thyrotoxicosis after discontinuation of antithyroid agents. RESULTS: We reviewed a total of 44 patients (29 females, 15 males; age, 48.93±18.04; range, 17-85 years). The recurrence rate was 27.3% (12/44 patients), and recurrence occurred 3 months to 12 months later resurfacing of subclinical thyrotoxicosis. Patients with recurred GD was significantly older than non-recurred patients (44.63±17.75 years vs. 58.58±15.48 years, p=0.02). Other clinical parameters measured at the time of initial diagnosis were not different between the two groups. CONCLUSION: The recurrence rate of GD in patients with resurfacing subclinical thyrotoxicosis after initial remission of the disease was less than 30%. A close monitoring is recommended in these subgroup patients, especially in older patients.

PURPOSE: The aim of this study was to identify the predictive factors in the early laboratory findings for cardiac sequelae in Kawasaki disease(KD). METHODES: A retrospective review of the records was conducted of all children with KD who were admitted to the Ulsan Dongkang General Hospital, Masan Samsung Hospital, and Gyeongsang National University Hospital between January 1995 and December 1999. We analyzed and compared the early laboratory findings between the patients with and without coronary artery dilatation. RESULTS: A total of 981 patients were divided into two groups : 826 patients(84.3%) with normal coronary artery and 155 patients(15.7%) with coronary artery dilatation. Age and sex were not significantly different between the two groups. The mean serum C-reactive protein(CRP) in the coronary artery dilatation group and in the normal coronary artery group were 5.0 mg/dl(+/-5.3) and 4.1 mg/dl(+/-5.0), respectively, with a significant difference(P<0.05), whereas the other early laboratory findings had no difference between the groups. CONCLUSION: This study shows that the early serum CRP was higher in patients with KD who had coronary artery dilatation than in those with normal coronary artery. There may be a strong possibility of cardiac sequelae at a high level of serum CRP. However, the cut-off value of serum CRP could not be determined for the prediction of cardiac sequelae in patients with KD.

OBJECTIVES: The purpose of this study was to investigate the prevalence and correlates of major and minor depressive disorders in college students. METHODS: A cross-sectional study was completed on a sample of 906 students (507 men and 399 women) with the self-administered form of Korean version of Mini International Neuropsychiatric Interview (K-MINI). RESULTS: Estimated 12-month prevalence of major depressive disorder was 4.2% in men and 9.5% in women, and that of minor depressive disorder was 15.4% in men and 23.2% in women. The factors, 'female gender' and 'age of 20-21', were significantly associated with major depressive disorder. 'Poor adaptation to school' was significantly associated with major depressive disorder both in men and women, but 'poor interpersonal relationship' and 'history of school withdrawal' were associated only in men. Idea of self-injury and suicidal behaviors (suicidal ideation, plan and attempt) were significantly associated with major depressive disorder in women, but were not associated with minor depressive disorder. CONCLUSION: Major and minor depressive disorders are highly prevalent in the college students. Major depressive disorder was more associated with dysfunctions and suicidal behaviors than minor depressive disorder. Campus-based mental health service is needed for the high-risk students.

OBJECTIVES: This study evaluated the prevalence of suicide-related behaviors (suicidal ideation, plan and attempt) and the status of depression, anxiety and function in college students. METHODS: A cross-sectional study was completed to a sample of 880 students with the self-administered form of Korean version of the Mini International Neuropsychiatric Interview (K-MINI), Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI). RESULTS: Estimated lifetime prevalence of suicidal ideation was 39.2%, that of suicidal plan was 4.7% and that of suicidal attempt was 3.0%. Students with any suicide-related behaviors showed higher lifetime prevalence of major and minor depression, higher BDI and BAI scores, and poor interpersonal relationship, adaptation to college life and physical health compared to the students with no suicide-related behaviors. The average points of grades during their college life were not significantly different according to kinds of suicide-related behaviors they experienced (F=0.39, p=0.82). 96% of suicidal attempters did not use mental health services. CONCLUSION: Results suggest that a high proportion of college students experience suicide-related behaviors. The students who had experienced suicide-related behaviors showed higher depression and anxiety and poorer function compared to students with no suicide-related behaviors. Most of suicidal attempters, however, did not use mental health service. Establishing campus mental health system is necessary to early detect mental health problems and to prevent suicide of college students.

This study was to investigate the effect of the education about general nutrition knowledge on the acceptance of TV food advertisements in adolescents. Twenty hours of nutrition related education in home economics classes were done during 3 months, to conveniently selected 784 first grade middle school students living in large and small cities and rural areas of Chungnam Province. The education effects were evaluated through questionnaire surveys before and after the education and their comparative analysis. Average TV watching time was 2.92 +/- 1.66 hours per day, which was about one hour longer on weekends. Nearly half of the subjects watched TV mainly after 9 PM. After nutrition education, nutrition knowledge scores of total subjects were significantly increased from 7.73 +/- 2.16 to 10.25 +/- 2.51 with a full score of 16. Food attitude and food habit scores also significantly increased from 32.45 +/- 4.65 (full score 50) to 33.93 +/- 4.68 and from 36.20 +/- 5.70 to 37.29 +/- 5.87, respectively. The general acceptance of TV food advertisements scored 25.25 +/- 4.44 (full score 40) before education and 26.90 +/- 4.55 after education, which was significantly raised by the education. Acceptance scores of TV food advertisements showed significant positive relationships with the scores of nutrition knowledge, food attitudes, and food habits. In addition, TV watching time had negative relationships with nutrition knowledge, food attitudes, and food habits scores, but not with acceptance score of TV food advertisements. The above results suggested that school-based nutrition education improved slightly but significantly the attitude of accepting TV food advertisements maybe through increasing nutrition knowledge and making food attitudes and habits better. Nutrition education focused on the evaluation and acceptance of food advertisements are further needed to improve the TV food advertisement acceptance of adolescents.
