UNLABELLED: Interleukin-22 (IL-22), which acts as either a proinflammatory or anti-inflammatory cytokine in various disease models, is markedly up-regulated in chronic liver diseases, including hepatitis B and C. In this report, we demonstrate a strong correlation between IL-22 expression in the liver with active, inflammatory human liver disease. To clarify the role of IL-22 up-regulation in the pathogenesis of liver diseases, liver-specific IL-22 transgenic (IL-22TG) mice, under the control of

CONTEXT: Although the histogenesis of sclerosing hemangioma is currently not well understood, the tumor has been characterized by its 2 histologically different types of cells, namely, surface and polygonal cells. OBJECTIVE: To elucidate the origin of these cells, we analyzed samples from 15 cases of sclerosing hemangioma and 15 specimens of fetal lung tissue. DESIGN: We immunostained specimens from 15 cases of sclerosing hemangioma and 15 samples of fetal lung tissue using antibodies against th

This study aimed to elucidate the demographic and sleeping environmental factors associated with sudden infant death syndrome (SIDS) in Korea. The autopsy reports of all SIDS cases reported to the National Forensic Service and Seoul National University College of Medicine between 1996 and 2008 were reviewed for data collection and analysis to identify the risk factors for SIDS. Analysis of the 355 SIDS cases reported within the study period revealed that of the 168 (47.3%) cases for which sleepi

Previous research on senior center attendance has focused mainly on the differences between senior center users and nonusers. However, this study explored the predictors distinguishing 3 categories of senior center users: users, nonusers, and former users. The data for this study were drawn from the 2004 National Survey on Living Status and Social Needs of the Korean Older Population, conducted jointly by the Korea Ministry of Health and Welfare and the Korea Institute for Health and Social Affa

This study examines the factors related to the frequency of senior center participation in Korea. The analyses are based on a sample of 316 Koreans, aged 65 and over, participating at a senior center in Chon-An City. The results show that gender, level of education, and health are statistically significant predictors of participation. That is, male Korean elderly, those who have a higher level of education, and those with better self-assessed health are more likely to participate at the center.
