  • Ultraviolet radiation (UV) is a major cause of photodamages to human skin and the immediate responses of the skin to UV include the erythema and edema. In an attempt to find effective UV-protecting agents to be used in cosmetics, a number of plant extracts were screened in the cell-based assays. Among the total of 38 plant extracts tested, 3 plant extracts derived from Sasa quelpaertensis, Althaea rosea, and Dryopteris crassirhizoma attenuated the UVB-induced cytotoxicity as well as melanin synthesis in cultured human epidermal melanocytes. The anti-inflammatory effects of these plant extracts were further examined in animal models. A control or test cream containing 1% of a plant extract was topically applied to ears of a C57BL/6 mouse or the dorsal skin of a SKH-1 hafirless mouse before and after the exposure to UVB. The change in ear thickness or dorsal skin redness due to UVB exposure was determined to monitor edema and erythema, respectively. All three test creams exhibited anti-inflammatory effects in both experiments. The creams containing Sasa quelpaertensis, Althaea rosea or Dryopteris crassirhizoma extract alleviated the UVB-induced edema response on day 4 by 53.8 %, 56.4 % and 31.1 %, respectively. They also inhibited the erythema formation on day 2 by 45.7 %, 34.1 % and 20.5 %, respectively. This study suggests that the selected plant extracts formulated in cosmetics may attenuate skin inflammation caused by overexposure to UV.

  • The purpose of this study was to investigate the dietary behaviors, eating habits, and nutrient intakes of elementary students with atopic dermatitis. Dietary conditions during infancy, dietary regularity, dietary behaviors, eating habits, and daily nutrient intakes were surveyed and compared between children with (WAD) and without (WOAD) atopic dermatitis using the 24-hr recall method. The ratio of children who responded 'I eat regular meals' was significantly lower in the WAD compared to WOAD group (76.4% vs. 81.7%, p<0.05). The ratio of children who answered 'I eat processed foods or fast foods more than once a week' (p<0.01) and 'I take nutritional supplements' (p<0.001) was significantly higher in the WAD compared to WOAD group. The scores for 'I eat milk and its products everyday' (1.4 vs. 1.5, p<0.05), 'I eat dishes fried or stirred with oil more than twice a week' (2.0 vs. 2.1, p<0.05), and 'I eat snacks such as ice cream, cake, snacks, carbonated beverages more than twice a week' (1.9 vs. 2.0, p<0.05) were significantly lower in the WAD group than in the WOAD group. Daily energy intakes were 1,859.1 kcal and 1,829.5 kcal in WAD and WOAD children, respectively, with no significant difference. However, daily intakes of fat (p<0.05), phosphorus (p<0.05), and vitamin $B_2$ (p<0.05) in WAD children were significantly higher than in WOAD children. To sum up, elementary students with atopic dermatitis had irregular eating habits and higher intake frequency of processed or fast foods, milk and its products, dishes fried or stirred with oil, and snacks compared to normal children. Dietary guidance and nutritional education are required to improve irregular eating habits and induce adequate nutrient intakes in children with atopic dermatitis.

  • In this study, we investigated the application of an extract from Ephedra sinica which has been composed of traditional Korean medicine as a whitening ingredient. The extract of Ephedra sinica which was obtained from the mixture of methanol and water (1:1) the inhibitory effect of tyrosinase. Then, Ephedra sinica was extracted by two different solvents. One was water and the other was methylene chloride. Only, the water extract of Ephedra sinica showed the inhibitory effort of tyrosinase; the anti-tyrosinase activity with $0.2\%$ of the water extract was $60.6\%$. But the extract of Ephedra sinica in methylene chloride fraction showed little inhibitory effect on tyrosinase. The inhibitory effect of the concentrated water extract of Ephedra sinica was tested on L-DOPA auto-oxidation and melanin synthesis in B-16 melanoma. In L-DOPA auto-oxidation, $0.5\%$ of the concentrated water extract showed $87\%$ of inhibition of L-DOPA auto-oxidation and the $0.75\%$ concentrated Ephedra sinica extract in wafer fraction inhibited $98.8\%$ of that. In melanin synthesis of B-16 melanoma, the concentrated water effect of Ephedra sinica inhibited $70.2\%$ or $79.9\%$ of inhibitory effect on that at the concentration of $0.05\%$ or $0.075\%$, respectively. For verifying the skin whitening effect of the concentrated water extract of Ephedra sinica in vivo, we performed the clinical test of that. The research showed the significant skin whitening effect of a cream containing $0.5\%$ Ephedra sinica extract and the statistical analysis showed a significant difference (p < 0.05) between sample (containing $0.5\%$ Ephedra sinica extract) and placebo after 10 weeks.

  • In order to develop new anti-photoaging agents from marine natural products, Zostera marina L. was selected for its antioxidative activity and inhibition of matrix metalloproteinase-1 (MMP-1) expression. Three compounds (compounds 1, 2, and 3) were isolated from the extract, and they were identified as apigenin-7-O-${\beta}$-D-glucoside (1), chrysoeriol (2), and luteolin (3). These compounds have SC$\_$50/ values of 0.18 mM, 0.68 mM, and 0.01 mM against l,l-dipheny1-2-picrylhydrazyl radical and 0.04mM, 0.03mM, and 0.01mM against the superoxide radical in the xanthine/xanthine oxidase system, respectively. Compound 3 suppressed the expression of MMP-1 by up to 44% at 35.0${\mu}$M and inhibited the production of interleukin 6, which is known as a cytokine that induces MMP-1 expression. In addition, the wrinkle improvement effect of the formulation with Z. marina extract was measured. As a result, remarkable reduction was found in the fine wrinkle and skin roughness after application of the cream with 3.0% this extract for 8 weeks. In conclusion, the isolated compounds from Z. marina extract were good antioxidant and suppressor of MMP-1 expression and the formulation with the extract diminished the skin wrinkle. Therefore, the extract can be used as a new anti-aging agent for application in cosmetic.
