RESUMO
BACKGROUND/OBJECTIVES: Chungkookjang is a Korean representative fermented soybean food. In this study, we investigated the effect of Korean traditional Chungkookjang compared with placebo on body composition, dyslipidemia and risk factors for atherosclerosis in overweight/obese subjects. SUBJECTS/METHODS: This double-blind, randomized, controlled crossover trial was conducted on 120 overweight/obese subjects, aged 19-29 years. Subjects were randomly divided into a Chungkookjang (n=60) or a placebo (n=60) group. After 12 weeks, the groups were crossed over for an additional 12 weeks. During the intervention period, subjects were asked to maintain their usual diet and activity and not to take any functional foods or dietary supplements. The anthropometric measures, lipid profiles and atherogenic indices were determined at baseline and at the end of each 12-week period. RESULTS: The anthropometry measurements, percentage body fat, lean body mass, waist circumference and waist-to-hip ratio of women in the Chungkookjang group were significantly improved compared with the placebo group. Lipid profiles and high-sensitivity C-reactive protein of women in Chungkookjang were significantly improved. The atherogenic indices of apolipoprotein B/apolipoprotein A1 decreased in both the placebo and the Chungkookjang group, and it also decreased below 0.55 for all the men and women in the Chungkookjang group. CONCLUSIONS: In conclusion, these results suggest that supplementation with Chungkookjang may improve body composition and risk factors for cardiovascular disease in overweight and obese adults.

The 3rd Schizophrenia International Research Society Conference was held in Florence, Italy, April 14-18, 2012 and this year had as its emphasis, "The Globalization of Research". Student travel awardees served as rapporteurs for each oral session and focused their summaries on the most significant findings that emerged and the discussions that followed. The following report is a composite of these summaries. We hope that it will provide an overview for those who were present, but could not participate in all sessions, and those who did not have the opportunity to attend, but who would be interested in an update on current investigations ongoing in the field of schizophrenia research.

OBJECTIVES: TNF-alpha, IL-1 and IL-6 are known to have primary roles in the pathogenesis of rheumatoid arthritis and other inflammatory diseases. The anti-rheumatic drug chloroquine has been shown to inhibit TNF-alpha, IL-1 and IL-6 production from mononuclear phagocytes. We examined the underlying mechanisms involved in the chloroquine-induced inhibition of cytokine production. METHODS: Human peripheral blood mononuclear cells and monocytes/macrophages and monocytic U-937 and THP-1 cells were stimulated with lipopolysaccharide, and TNF-alpha, IL-1beta and IL-6 production was measured by ELISA. Levels of mRNA were measured by northern blotting and reverse transcription-polymerase chain reaction. Synthesis of 26-kDa TNF-alpha precursor was measured by metabolic labelling and immunoprecipitation analysis. Transcription rate was determined by nuclear run-on assay. RESULTS: TNF-alpha release from the cells was inhibited by chloroquine, whereas the steady-state level of TNF-alpha mRNA and synthesis of 26-kDa TNF-alpha precursor were not changed by chloroquine. In contrast, chloroquine-induced inhibition of IL-1beta and IL-6 release was accompanied by a decrease in their steady-state mRNA levels. The transcription rates of the IL-1beta and IL-6 genes were not changed by chloroquine, whereas the stability of IL-1beta and IL-6 mRNA was decreased by chloroquine. Weak-base amines such as methylamine and ammonium chloride had no effect on the production of TNF-alpha, whereas they partially blocked the production of IL-1beta and IL-6. CONCLUSIONS: Our results indicate that chloroquine-mediated inhibition of TNF-alpha, IL-1beta and IL-6 synthesis occurs through different modes in lipopolysaccharide-stimulated human monocytes/macrophages: it blocks the conversion of cell-associated TNF-alpha precursor to mature soluble protein, whereas it reduces the levels of IL-1beta and IL-6 mRNA, at least in part, by decreasing their stability and by a pH-dependent mechanism.
