Homer protein was identified based on its rapid induction in rat hippocampal granule cell neurons following excitatory synaptic activity. Although the presence of the Homer gene in the peripheral tissues has been observed in previous reports, the physiological function of the Homer protein in these tissues has not been noted. In this experiment, a Homer-2a cDNA fragment was successfully amplified by RTPCR in the involuting phase of human hemangioma but not in the human vascular malformation and normal vessel. After isolation of full Homer cDNA in a mouse liver cDNA library, E1-deleted recombinant adenovirus expressing the Homer protein (Adv.CMV.mHomer-2a) was constructed to determine its physiological function in peripheral tissues. Adv.CMV.mHomer2a, but not Adv.CMV.LacZ (recombinant adenovirus expressing beta-galactosidase), strongly inhibited the growth rate of HUVECs (human umbilical vein endothelial cells) probably via inducing apoptosis determined by acridine orange/ethidium bromide (AO/EB) staining methods. This study suggests that the Homer gene is present in human specimens in the involuting phase of hemangioma, and it might be involved in the growth control.

OBJECTIVES: The purpose of this study was to evaluate gender differences with respect to the internalization or externalization of symptoms according to the amount of time spent engaged in extracurricular education. METHODS: The study included a community sample of 755 boys and girls (mean age, 6.6 years), collected from five elementary schools in Gunpo, South Korea. Primary caregivers completed a questionnaire which included information on demographics, the amounts of time children spent in extracurricular education and with other activities, and an adapted form of the Behavior Assessment System for Children (BASC-2). Gender differences regarding externalizing and internalizing behavior problems were examined according to extracurricular education. RESULTS: With respect to the boys, there was a difference in the frequency of those who had externalizing behavior problems according to their time spent in extracurricular education. In contrast, the girls exhibited no difference. With respect to those children who spent a lot of time engaged in extracurricular education, there was a gender-specific difference only with respect to externalizing behavior problems. CONCLUSION: A gender-specific difference exists only in terms of externalizing behavior problems according to time spent engaged in extracurricular education.

OBJECTIVES: Alcohol withdrawal delirium is a serious clinical condition with high mortality rate if not treated. This study was to examine whether readily available clinical variables can predict the development of alcohol withdrawal delirium. METHODS: The authors performed a retrospective study by reviewing charts of 566 patients who had been admitted for alcohol dependence. The cases were divided into two groups: delirium group (n=40) and control group (n=40). We compared baseline characteristics and serum analysis data at admission between two groups. We used logistic regression to predict risk factors for alcohol withdrawal delirium among potential risk factors. RESULTS: The delirium group had significantly lower hemoglobin, hematocrit, platelet counts, and potassium level than countrol group. Presence of previous withdrawal delirium history, AST, GGTP, and bilirubin level of delirium group were significantly higher than those of control group. Among potential risk factors, past history of withdrawal delirium, decreased hemoglobin, elevated bilirubin level, and number of previous detoxification were predictable factors of the development of alcohol withdrawal delirium by 72.5%. CONCLUSION: Our results suggest that the infomation obtained at admission can be useful to predict the development of alcohol withdrawal delirium. Also, it makes the individualization of detoxification strategies possible.
