Abstracts

The effect of extract of Korean wine waste on the production of nitric oxide (NO) and cytokines in splenocytes and RAW 264.7 cells was investigated using lipopolysaccharide (LPS) as a stimulant. Treatment of RAW 264.7 cells with the 85% aqueous methanol (MeOH) fraction from Korean wine waste reduced LPS-induced NO production in a dose-dependent manner (p<0.05). Culture supernatants of splenocytes exposed to a co-treatment of 85% aq. MeOH fraction and LPS were harvested to determine the production levels of cytokines [IL-2, IL-4, IL-5, IL-6, IL-12/IL-23(p40) and IFN-γ]. As measured by ELISA, co-administration of 85% aq. MeOH fraction (10 μg/mL) with LPS significantly reduced the IL-2 expression after 48 h of treatment, as compared to treatment with only LPS (p<0.05), where the level of IL-6 expression was significantly lower after 24 h of the co-treatment (p<0.05). The IL-12/IL-23(p40) expression levels after 24 and 72 h of co-treatment were also significantly lower than that from LPS treatment only (p<0.05). However, the IL-4 and IFN-γ expression levels were significantly lower only after 72 h of co-treatment. These results indicate that the 85% aq. MeOH fraction from Korean wine waste decreased the production of NO as well as the expression of the pro-inflammatory cytokines IL-2, IL-6 and IL-12/IL-23(p40).
