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.

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.
