This study aimed to identify mordant effects of Chestnut hulls. The color of post and pre-mordanted fabrics were measured in terms of H, V, C, $L^*$, $a^*$, $b^*$, and K/S values. In addition, color fastness and antimicrobial activity were evaluated. The pre-mordant concentration of Chestnut hulls for cotton, mercerized cotton and silk was optimized to 50% (o.w.f.) and 70% (o.w.f.), respectively. Post-mordant concentration of Chestnut hulls of mercerized cotton, silk and cotton was optimized to 50% (o.w.f.) and 90% (o.w.f.), respectively. The hue of fabrics was influenced by mordant methods, such as pre-mordant and post-mordant, slightly. Wet cleaning fastness of pre-mordanted cotton and mercerized cotton fabrics was higher than that of post-mordanted fabrics. The wet cleaning fastness of silk fabrics was not affected by the mordant method, and their fastness were proved to be excellent. The dry cleaning fastness of post-mordanted cotton fabrics was higher than that of pre-mordanted cotton fabrics. The dry cleaning fastness of mercerized cotton and silk was proved to be excellent regardless of mordant methods. The antimicrobial activity of Oenothera odorata jacquin dyed fabrics and Chestnut hulls mordanted fabrics was proved to 99.9%, and their excellent antimicrobial activity remained after wet and dry cleaning.

Objectives : Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by eczematous inflammtion of the skin. The chestnut inner shell extracts (CI) has been used as a cosmetic material for a long time in Korea. However, the precise anti-allergy effects of CI have yet to be clearly elucidated. In this study, we attempted to evaluate the effect of CI on mast cell-mediated allergy inflammation. Methods : To find the anti-allergy and inflammatory effect of CI, we investigated the inhibitory effect of CI on the production of inflammatory mediators using by enzyme-linked immunosorbent assay in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore (A23187) stimulated-human mast cell (HMC-1). Results : In this study, we found that CI did not show cytotoxic effect at up to 10 ug/ml on HMC-1. CI inhibited the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6 and IL-8 in stimulated HMC-1. Maximal rate of TNF-${\alpha}$, IL-6 and IL-8 inhibition by CI (10 ug/ml) were about 47.6%, 44.1% and 22.5% respectively. In addition, we showed that Fr.3 isolated from n-Butyl alcohol layer of CI attenuated the production of TNF-${\alpha}$, IL-6 and IL-8 in HMC-1. Conclusion : Taken together, the findings of this study provide us with a novel insight action of CI as a potential molecule for use in the treatment of allergic inflammation diseases.

In this study, we investigated the potential of Lactobacillus brevis AR1 fermented broth containing various grains (Fagopyrum esculentum, Scotch oat, Sesamum indicum, Glycine max Merr, Castanea crenata, Oryza sativa L., Hordeum vulgare L., Perilla frutescens var. japonica Hara, or Triticum aestivum L.) or Saccharina japonica as a source of collagen synthesis in cosmetic products. The treatment of Lb. brevis AR1 fermented broths containing F. esculentum or S. japonica water extracts was markedly increased the synthesis of collagen in fibroblasts. The collagen synthesis capacity of the S. japonica fermentation product was higher than that of β-glucan, which was used as a positive control. Under controlled conditions in broths containing F. esculentum or the S. japonica extracts with 4% monosodium glutamate (MSG), Lb. brevis AR1 produced γ-aminobutyric acid (GABA) at a concentration of 180 mM, with an 84.5% GABA conversion rate after 72 h. Both the F. esculentum and S. japonica fermentation broths produced by Lb. brevis AR1 reduced inflammatory responses on mouse skin and did not show cell cytotoxicity in fibroblasts. These results suggest that both the F. esculentum and S. japonica fermentation products of Lb. brevis AR1 could be used as functional materials in cosmetic products to combat wrinkles and skin inflammation.

Objectives : This is the study of the application as the ingredients of cosmetics through the examination of the function for physiological activity of Chestnut inner shell. Methods : Chestnut inner shell, which had been extracted, concentrated, and freeze drying with water and ethanol, have been used for the experiment. The effects on electronic donating ability, SOD-like activity, xanthine oxidase inhibition, whitening effect, nitric oxide inhibition have been investigated in the physiological activity measurement of function experiment. Results : We used BHA and kogic acid for the comparative. As a result of testing electron donating ability, at over 100ppm of water extract and ethanol extract, BHA showed relatively high donating ability by more than 90%. And as a result of measuring SOD like activity, 1000ppm of water extract showed an effect of 30% and ethanol extract showed an effect of 40%, BHA showed an effect of 30%. In the xanthine oxidase inhibition test, 1000ppm of water extract showed an effect of 70% and ethanol extract showed an effect of 63%, BHA showed an effect of 100%. In the tyrosinase inhibition test, 1000ppm of water extract showed an effect of 55% and ethanol extract showed an effect of 87%, Kogic acid showed an effect of 98%. In the anti-inflammatory test, the water extract and ethanol extract inhibited the generation of nitric oxide. Conclusions : The results indicated that extract of Chestnut inner shell can be used as a natural ingredients with biological function in cosmetics ingredients.
