And I observed each group of mice after 24, 48 and 72 hours. results : 1. With the result of Contact hypersensitivity assay, YST group shows appreciably less ear swelling than ACD group. 2. Comparing YST and ACD groups to each other regarding general change of skin, YST group shows less hyperplasia of epidermis, less migration of inflammatory cells and less damage of epidermis than ACD group. 3. Regarding the change of collagen fiber, ACD group has appeared to be low in number of collagen fiber while YST shows similarity with the contrastive group. 4. In dermis YST group has showed lower number of mastocyte than ACD group and is granulated type. 5. In dermis YST group has showed less MAC-1, IL-1 , $IL-2R-\;{\alpha}$ G, ICAM-1 and VCAM-1 than ACD group. 6. The distribution of apoptotic cells has appeared littler in YST group than in ACD 7. Among signal molecule of apoptosis Bcl-2 has distributed more in YST group than ACD group and Bax and Fas has distributed less in YST group than ACD group.

The aim of this study was to investigate the effect of Fructus Forsythiae on the melanogenesis. To determine whether Fructus Forsythiae methanol extract suppress melanin synthesis in cellular level, HM3KO human melanoma cells were cultured in the presence of various concentrations of Fructus Forsythiae methanol extract and the effects on cell proliferation, tyrosinase activity and melanin contents were examined. Treatment with Fructus Forsythiae methanol extract inhibited tyrosinase activity, regulate melanin biosynthesis as the key enzyme in melanogenesis, in a dose-dependent manner. And also suppressed melanin contents as a dose dependent manner without cytotoxicity morphological change. It was observed that the color of cell pellets was totally different from the control. These results suggest that the inhibitory effect of Fructus Forsythiae methanol extract on melanogenesis is due to the suppression of tyrosinase in HM3KO cells and Fructus Forsythiae is a candidate for an efficient whitening agent.

Purpose: Contents of astragaloside I, II and IV, cytotoxicity, anticancer activity, immunomodulatory activity and antioxidant capacity were to be compared as a function of the cultivated years as one, three, five and seven years. Method: Major components of Astragali membranacei Radix were separated as astragaloside I, astragaloside II, astragaloside IV by HPLC analysis. Cytotoxicity and anticancer activities were measured by MTT and SRB assay. For immunomodulatory activity, the secretion of IL -6 and $TNF-{\alpha}$, NK cell activation and macrophage activation were observed as well as kinetics of responding to human T cells by a microphysiometer. In vitro antioxidant activities were measured by several radical scavenging activities of superoxide anion radican, DPPH, LDL and linoleic acid. For in vivo activity, the activation of SOD, GSH-px, catalase, ALDH and ADH was measured as well the relative weight of liver. Result : 1. For HPLC analysis, the contents of all of astragaloside I, astragaloside II, astragaloside IV were in order of three, five, one and seven years. 2. The cytotoxicity of normal human lung cell line, HEL299 showed lower than 18% in adding 0.25 mg/ml, and 28.9% in adding 1.0 mg/ml of water extract of seven year root. For methanol extracts, three year root showed highest cytotoxicity as 35.2 % and there was no difference between the cultivated years. 3. For anticancer activities, methanol extracts of one and three year roots showed relatively high inhibition of human stomach cancer cells, AGS, breast cancer cells, MCF-7, lung cancer cells, A549 and liver cancer cell, Hep3B as well as high selectivities. 4. The water extract of seven year root could yield high secretion of IL-6 from both human Band T cells while the methanol extracts of three and five year roots secreted high amounts of IL-6 and $TNF-{\alpha}$ from both Band T cells. 5. As a result of in vitro antioxidant activities, both water and methanol extracts from five and seven year roots showed high activities for superoxide anion radical scavenging activity, inhibiting linoleic acid peroxide and contents of total phenols. 6. For in vivo tests, Mn-SOD and GSH-px activities and weight of liver were better in adding seven year root. For ALDH activity one year root was better and for ADH activity five year root. Overall speaking, seven year root showed relatively better antioxidant activities. Conclusion:There was difference of the contents of astragaloside I, astragaloside II, astragaloside IV according to cultivation year. Methanol extract showed better activities of anticancer and immune activation rather than water extract Interestingly enough, for methanol extracts, overall activities were improved as the cultivation year increased. There might be further investigation required for the clinical uses of the results as several biological activities varied according to the cultivated year of Astragali membranacei Radix.

(1) Objectives: To discover natural skin-lightening agents, we have evaluated the inhibitory activity of EtOH extracts from 20 medicinal plants against mushroom tyrosinase. (2) Methods: Tyrosinase activity was determined by the dopachrome method using L-tyrosine as the substrates. (3) Results: Of the plant extracts tested, the extracts of 4 plants, Albizzia julibrissin, Curcuma longa, Anethum graveolens and Sophora flavescens, exhibited potent inhibitory activity (> 50%) in mushroom tyrosinase assay. Four plant extract, extracts of Agrimonia pilosa, Paeonia moutan, Magnolia obovata and Eugenia caryophyllata also showed relatively strong inhibitory (> 40%) against mushroom tyrosinase.

This paper provides comparison and analysis between brand images of Korean herbal cosmetics and general, imported cosmetic brands, focusing on product's symbolic and functional images. The objective is to evaluate brand images of Korean herbal cosmetics to suggest a powerful brand image strategy that will be different and competitive. Data collection was performed on 300 adult women who were over 20 years of age and lived in Seoul or KyongKi area. Analysis was carried out using SPSS version 11.5 and frequency analysis, T-Test and $X^2$ verification was also performed. Analysis results for brand images of Korean herbal cosmetics are as follows. First, satisfaction scale as a purchase feature for users of Korean herbal cosmetics were 'Normal' 51.5%, 'Satisfactory' 35.1%, 'Very Satisfactory' 8.2% and 'Unsatisfactory' 5.2%. Regarding improvements, 'Efficacy, Effect' was the highest with 46%. Second, 'SEOLHWASOO' and 'BAEKOKSENG' among Korean herbal cosmetic brands, 'IOPE' and 'ISA KNOX' among general cosmetic brands and 'LANCOME' and 'CHANEL' among imported cosmetic brands displayed high recognition. Third, the symbolic and functional images of Korean herbal cosmetic brands were seen to be better compared to their general and imported counterparts. Especially, product related features of Korean herbal cosmetic brands received a more positive response compared to imported brands, which suggests that with research and improvement regarding non-product related features, functional images of herbal brands may be appraised ahead of imported brands. Fourth, there is a significant difference in brand preference according to the satisfaction of groups who actually use herbal cosmetics and the purchasing attitudes of groups who do not. Therefore, an active relationship marketing strategy is required to maximize satisfaction and to elicit favorable attitudes. By developing functional native ingredients, constructing data that can prove its efficacy and effects, and appealing its unique, differentiated symbolic value together with Orientalism, herbal medicines will be able to take off to be acknowledged worldwide.

Acute Mastitis(急性乳腺炎=乳癰) is an acute suppurative disease appearing in the breast. It is mostly caused by galactostasis, the stagnation of liver-qi(肝鬱) and stomach-heat(胃熱). It is mostly found in breast feeding women, mostly in primiparae. It usually appears in the third and the fourth weeks of postpartum. At the beginning in the chest there appear induration, distending pain, galactostasis, inversion to cold with fever followed by the enlargement of the masses, burning red, megalgia, not subduing of chills and fever, the accumulation of it to form pus. In the early phase it is advisable to follow the therapeutic principles of soothing the liver and clearing away heat, promoting lactation and subduing swelling. After the formation of pus it is advisable to cut radially and drain the pus. External Therapy(外治法) generally refers to all the methods to treat various diseases and symptoms with application of drugs and manipulation or together with proper instruments on the body surface except the method of taking medicine orally Acute Mastitis has been regarded as surgery or the method of taking medicine orally But, based on many bibliographies, acute mastitis was treated by external therapy. Thus through the historical bibliographic studies of external therapy about acute mastitis, this study was made to help the expanding of the methods of treating acute mastitis.
