Ginseng has been widely used for therapeutic and preventive purposes for thousands of years. However, orally administered ginseng has very low bioavailability and absorption in the intestine. Therefore, fermented ginseng was developed to enhance the beneficial effects of ginseng in the intestine. In this study, we investigated the molecular mechanisms underlying the anti-inflammatory activity of fermented wild ginseng (FWG). We found that FWG significantly alleviated the severity of colitis in a dextran sodium sulfate (DSS)-induced colitis mouse model, and decreased expression level of pro-inflammatory cytokines in colonic tissue. Moreover, we observed that FWG suppressed the infiltration of macrophages in DSS-induced colitis. FWG also attenuated the transcriptional activity of nuclear factor-κB (NF-κB) by reducing the translocation of NF-κB into the nucleus. Our data indicate that FWG contains anti-inflammatory activity via NF-κB inactivation and could be useful for treating colitis. © 2015 by the The Korean Society for Biochemistry and Molecular Biology.

This study evaluated the protective effects of dietary supplementation with a fermented barley and soybean mixture (BS) on ultraviolet (UV) B-induced photoaging in hairless mice. Skin aging-related parameters and protein levels related to skin wrinkles and moisturization in mice were analyzed. The BS reduced wrinkle formation, skin thickening, transepidermal water loss, and matrix metalloproteinases-1 expression in skin. Skin hydration and pH were increased in the BS group. BS attenuated filaggrin expression as well as free amino acid and glycerol production. BS increased superoxide dismutase activity as well as increased expression of nuclear factor (erythroid-derived 2)-like 2, procollagen type-I, and decreased erythema. These results suggest that BS protects against photoaging induced by UVB in vivo, indicating the potential of such mixtures as anti-photoaging dietary supplementation. © 2015, The Korean Society of Food Science and Technology and Springer Science+Business Media Dordrecht.

Inflammatory bowel disease (IBD) is characterized by chronic or relapsing immune system activation and inflammation within the gastrointestinal tract. The lack of safety and efficacy of standard therapies, the use of food supplements for managing IBD is increasing, and many studies have reported that various food supplements provide many beneficial effects for the IBD.This study aimed to evaluate the anti-colitis effects of dietary supplementation with a fermented barley and soybean mixture (BS) on intestinal inflammation using a murine model of IBD. Female C57BL/6 mice were administered with either BS (100 and 200mg/kg/day) or vehicle (PBS) control through oral gavages for 3days and received 5% dextran sulfate sodium (DSS) drinking water to induce colitis. Mice body weight was measured every two days and disease activity index (DAI) score was determined on Day 15; mice were sacrificed and colons were analyzed by H & E staining and RT-PCR. We also measured intestinal barrier function in vitro using DSS-treated Caco-2 cells by assessing ZO-1 immunofluorescence staining and Western blotting and in vivo by measuring serum level of FITC-Dextran and by performing bacteria culture from mesenteric lymph nodes (MLN) extract. The gut microbiota was examined by real time PCR using fecal DNA.We found that BS alleviated the severity of colitis in a DSS-induced colitis mouse model, and suppressed levels of pro-inflammatory cytokines in colonic tissue. Moreover, BS prevented epithelial barrier dysfunction, inducing an increase of tight junction protein levels in colonic tissues, BS also inhibited FITC-dextran permeability, and suppressed bacterial translocation to MLNs. In addition, BS increased the levels of Lactobacilli and Bacteroides, which have anti-inflammatory properties.Our study suggests that BS has protective roles against inflammatory bowel disease through changes in inflammatory activity, tight junction protein expression, and gut microbiota composition in DSS-induced colitis.

Skin hydration is one of the primary aims of beauty and anti-aging treatments. Barley (Hordeum vulgare) and soybean (Glycine max) are major food crops, but can also be used as ingredients for the maintenance of skin health. We developed a natural product-based skin treatment using a barley and soybean formula (BS) incorporating yeast fermentation, and evaluated its skin hydration effects as a dietary supplement in a clinical study. Participants ingested a placebo- (n=33) or BS- (3g/day) containing drink (n=32) for 8 weeks. A significant increase in hydration in the BS group as compared to the placebo group was observed on the faces of subjects after 4 and 8 weeks, and on the forearm after 4 weeks. Decreases in stratum corneum (SC) thickness were also observed on the face and forearm. BS enhanced hyaluronan (HA) and skin barrier function in vitro and reduced Hyal2 expression in human dermal fibroblasts (HDF). BS also recovered ultraviolet (UV) B-induced downregulation of HA in HaCaT cells. These results suggest that BS has promising potential for development as a health functional food to enhance skin health.
