This study provides an eco-friendly dyeing processing for chitosan fiber using Oenothera odorata jacquin as a dye. The effects of chemical mordants (Al, Cu, Fe) and natural mordant (Chestnut shell) on the color change for dyed chitosan fibers were measured by K/S values, L, $a^*$, $b^*$, H, V, C values, color fastness, and antimicrobial activity. The results are as follows. Dyeing conditions of Oenothera odorata jacquin on chitosan fibers were optimized to $70^{\circ}C$, 30 minutes and 200% on weight of fabric (o.w.f.). The pre-mordant concentration of aluminium (Al), copper (Cu) and iron (Fe) of chitosan fibers was optimized to 3% (o.w.f.) and 1% (o.w.f.), respectively. The post-mordant concentration of chemicals, such as Al, Cu and Fe, on chitosan was determined to 1% (o.w.f.). The hue of chitosan fibers by chemical mordants was measured to be reddish & yellow. The pre-mordant concentration of Chestnut shell of chitosan was optimized to 70% (o.w.f.). The post-mordant concentration of Chestnut shell on chitosan was determined to be 50% (o.w.f.). The hue of chitosan fibers by Chestnut shell mordant was measured to be reddish & yellow. The wet cleaning fastness of chitosan fibers was improved by a pre-mordant that used chemical mordants. In the case of the Chestnut shell mordant, the wet cleaning fastness was improved by a post-mordant. The dry cleaning fastness of chitosan fibers was excellent regardless of mordants and mordant methods. The antimicrobial activity of the chitosan fiber was shown at 99.9% and its excellent qualities remained after the dyeing and mordant processing.

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.

본 연구에서는 각종 곡물(메밀, 귀리, 검은깨, 검은콩, 율피, 현미, 보리, 들깨, 밀) 및 다시마를 포함하는 Lactobacillus brevis AR1의 발효물 중에서 섬유아세포의 콜라겐 합성을 촉진하는 화장품 소재를 조사하였다. 그결과 메밀 및 다시마를 포함하는 Lb. brevis AR1의 발효물을 처리한 섬유아세포에서 효과적으로 콜라겐 합성이 증가하였다. 특히, 다시마 함유 Lb. brevis AR1의 발효물은 양성 대조구인 β-glucan 보다 높은 콜라겐 합성능을 나타내었다. Lb. brevis AR1은 메밀 또는 다시마와 함께 4% MSG를 첨가한 배지에서 72시간 배양한 후, 180 mM의 GABA를 생산하여 84.5%의 GABA 전환율을 나타내었다. 메밀 및 다시마를 포함하는 Lb. brevis AR1의 발효물은 생쥐 피부의 염증 반응을 감소시키는 효과를 가졌고 섬유아세포에서는 세포 독성을 나타내지 않았다. 이 결과들은 메밀 및 다시마를 포함하는 Lb. brevis AR1의 발효물이 피부 주름 개선과 항염증 효과를 가지는 기능성 화장품 소재로서 사용될 수 있다는 것을 나타낸다.

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.
