Tumor necrosis factor-n (TNF - alpha) involved in the pathogenesis of multiple sclerosis and contribute to the degeneration of oligodendrocytes as well as neurons. TNF - alpha is produced by miocroglia and astrocytes, which also produce hormones and cytokines that influence its biological activity. Astrocytes, the major glial cells in the CNS, are capable of producing TNF - alpha at both the mRNA and protein levels in response to interleukine-1 (IL-1) or TNF - alpha. Two immunosuppressive cytokines, transforming growth factor - beta (TGF - beta) and IL-10, have been shown to influence glial cell function. TGF - beta can modulate the activity of glial cells by inhibiting interferon-gamma (IFN - gamma) induced expression of class II major histocompatibility complex (MHC) molecules on astrocytes and microglia. To explore the role of astrocytes in the production of TNF - alpha, astrocytes were pretreated with IL-10 or TGF - beta and then stimulated with IL-1p to determine their effects on TNF - alpha production. The secretion of TNF - alpha by human fetal astrocytes was markedly inhibited by TGF - beta at a low concentration. In contrast IL-10 had no effect on TNF - alpha mRNA level. These results show that TGF - beta may regulate the expression of TNF - alpha in activated human fetal astrocytes.

PURPOSE: This study was conducted to investigate influencing factors on recovery among alcoholics. METHODS: The participants were 123 hospitalized patients with alcohol use disorder in two hospitals in Gyeonggi province. The data were collected from May 16 to June 4, 2012 using self-report questionnaires including Hanil Alcohol Insight Scale, Alcohol Abstinence Self-Efficacy Scale, and Recovery Scale. The data were analyzed using the SPSS/Win 18.0 program with descriptive statistics, Pearson's correlation coefficient and regression analysis. RESULTS: Recovery is positively related to abstinence self-efficacy and duration of abstinence. Recovery differed by insight type, gender, and occupation. Insight, duration of abstinence, gender, and occupation accounted for 59.1% of the variance in recovery of the alcoholics. CONCLUSION: The influencing factors on recovery among alcoholics were insight, duration of abstinence, gender, and occupation. Programs focusing on insight, abstinence self-efficacy, and abstinence maintenance should be developed and provided. When developing the programs, the environmental context in which the alcoholics work should be considered.

PURPOSE: This study was done to examine the association among irrational belief, mental health, and self-efficacy, and explored the mediation of self-efficacy in the relationship between irrational belief and mental health of Korean soldiers. METHODS: A cross sectional study design was employed. The participants were 118 soldiers who signed consent forms. Data were analyzed using descriptive statistics, Pearson correlation coefficients, and multiple regression analysis. RESULTS: Irrational beliefs were positively correlated with mental health problems, and self-efficacy was negatively correlated with irrational beliefs and mental health problems. Self-efficacy acted as a mediator in the relationship between irrational beliefs and mental health problems. CONCLUSION: The study results suggest that effective interventions to reduce mental health problems of soldiers should apply strategies to change irrational belief and increase self efficacy. These results also provide more empirical support to the hypothesis that self-efficacy serves as a mediator in a mental health.

PURPOSE: This study was to explore the effects of breast cancer education for college students on their mother's breast cancer screening promotion. METHODS: This study used a one-group pretest and posttest design. Data were collected from September to November, 2007 from a sample of 80 college students and their mothers using a survey questionnaire, which asked about demographic variables, concerns over health and breast cancer, communication, stage of change and attitude (pros and cons) related to breast cancer, and confidence in breast self-examination. The college students received education about breast cancer for 50 minutes and then they educated their mothers about breast cancer. Data were analyzed with descriptive statistics and paired t-test. RESULTS: The mean age of the college students was 22.0 years, and that of their mothers 49.4 years with a range from 43 to 58 years. After receiving education on breast cancer, there were significant changes in the mean scores of concerns about health and breast cancer, communication, pros in mammography, and confidence in practicing breast self-examination. CONCLUSION: This study indicates that education on breast cancer to mothers through their college-age daughters is effective and can be utilized to promote breast cancer screening for women.

Purpose:
This study systematically reviewed and analyzed the effects of non-pharmacological interventions on internalized stigma among people with severe mental illness.
Methods:
A systematic review and meta-analysis were conducted following the Cochrane Intervention Research Systematic Review Manual and Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. This study targeted people with severe mental illness as the population, interventions aimed at reducing internalized stigma, comparisons with control groups, and internalized stigma as the outcome. A literature search was performed across multiple databases, including PubMed, EMBASE, the Cochrane Library, CINAHL, PsycArticles, RISS, KMbase, and KoreaMed. The risk of bias was evaluated using the Cochrane Risk of Bias 2.0 tool. Effect sizes were computed using Hedges’s g, and subgroup analyses were conducted with Comprehensive Meta-Analysis software version 4.0.
Results:
Of 2,388 papers, 15 were included in the meta-analysis. The overall effect size (Hedges’s g) of the intervention was –0.60 (95% confidence interval, –1.01 to –0.19), indicating a statistically significant reduction in internalized stigma (Z=–2.88, p=.004). Subgroup analyses revealed that the intervention type (p=.008) and session length (p=.011) were significant moderators influencing the effectiveness of the interventions.
Conclusion
Tailoring interventions by considering variables such as the intervention type and session length could enhance the effectiveness of non-pharmacological interventions for reducing internalized stigma among people with severe mental illness (PROSPERO: CRD42023418561).
