Biotae Orientalis has been widely used for treatment of relaxion of smooth muscle, gastrointestinal hemorrhage and alopecia in Oriental Medicine. This experiment examined the effect of an extracts, obtained from the acetone and MeOH extracts of dried or fresh Biotae Orientalis, on hair growing activity of the C57BL/6N mice after topical application to skin. First, We examined on hair growth activity of extracts of Biotae Orientalis compare to control and 1% minoxidil groups. Second, We investigated on the number of hair follicle and mast cells after topical application of extracts of the Biotae Orientalis to skin for 16 day. Third, We investigated immunoreactive density of vascular endothelial growth factor(VEGF), protein kinase C-${\alpha}$(PKC-${\alpha}$) and stem(mast) cell factor(SCF) in skin of C57BL/6N mice by immunohistochemical methods. I fourth investigated changes of subpopulation of splenocytes and thymocytes in C57BL/6N mice for 16day using laser flow cytometry. The results were as follows : Hair growing effect of acetone and MeOH extracts of dried and fresh Biotae Orientalis was observed in 70%, 90% and 60% in hair removed skin area in 16 day respectively. Immunoreactive density of VEGF and PKC-${\alpha}$ in skin of experimental groups was weakly stained compare to control group in 10 day. Immunoreactive density of stem cell factor in skin of experimental group was heavily stained compare to control group in 10 day. Splenic TH/TC Iymphocytes of lived MeOH extracts group significantly increased compare to control group. TH cells in thymic T lymphocytes were increased compare to control group. These experiment suggest that acetone and MeOH extracts of Biotae Orientalis may be used for topical treatment of alopecia areata.

The unique biochemical pathways in melanocytes responsible for melanogenesis provide us with a rational mechanism-based means for developing both pharmacological regulators of pigmentation and cytotoxic chemotherapeutic drugs for melanoma, Myricetin is a polyphenolic antioxidant and a component from Biotae Semen, Biotae orientalis Folium. Therefore, the present study was conducted to evaluate the effects of myricetin on the melanogenesis in human melanoma (HM₃KO) cells. The cells were treated for 5 days with myricetin at several concentrations (10 - 100 μg/ml). Treatment with myricetin dose-dependently suppressed cell growth in HM₃KO cells, But melanin formation was markedly increased by myricetin as a dose dependent manner. Myricetin did not affect to tyrosinase activity, which is a key enzyme for melanogenesis, but significantly increased the level of tyrosinase protein expression, These results suggest that myricetin stimulate melanin synthesis of human melanoma cells through the modification of tyrosinase protein expression.

In order to investigate the amino acid and fatty acid content in Thuja biotae water extract treated with alkaline, it was performed. There are 16 kinds of different amino acid and 20 kinds of different fatty acid in Thuja biotae water extract. An aspartic acid was contained 52％ and proline was contained 10％, particulary, r-aminobutyric acid was analysed. Essential fatty acids; linoleic acid, linolenic acid and arachidonic acid were cotained a lot amount. There are 11 different unknown materials which were identified by GC-MS spectrum, such as N-[($4{\alpha},5{\alpha}$)-cholestan-4-yl]-acetamide; 22,26-Epithio-furost-5-en-3-ol; 2-Methyl-6-(4-methyl-3-cyclohexen-1-yl)-4-heptanone; 3,12,14-Tris(acetyloxy)-pregnane-15,20-dione;22-Methyl-26-thio-furost-5-en-3-ol; 7-Ethenyl-1,2,3,4,4a,4b,5,6,7,9,10,10a-dodecahydro-1,4a,7-trimethyl-1-phenanthrene carboxyaldehyde; Methoxyiminopro-panedioic acid; 13-Methyl-13-${\beta}$-Methyl-13-vinyl-dodecaarp-7-en-3-3-ol; 22-Methyl-26-thio-furost-6-methyl-3-ol; $5{\alpha}-Androstane-2$,11-dione; 9-Methyl-heptadecanoic acid.

The effect of Thuja biotae water extract on lipid composition, blood glucose, cholesterol, triglyceride and lipid hydroperoxide was studied in rabbits. In the animalfed Thuja biotae water extract $1m{\ell}/kg\;or\;2m{\ell}/kg$, blood glucose, cholesterol, triglyceride and lipid hydroperoxide was lower values than the control group. The lipid composition of plasma was not great differencies, but palmitic acid $C_{16:0}$ was very elevated with higher than 50%, n-3/n-6 ratio was higher than 0.3 and p/s ratio was higher than 4.0. It was concluded that Thuja biotae water extract may be one of the blood glucose, cholesterol and triglyceride level lowering factor.

The effect of seventy kinds of medicinal plants on the activities of GABA-metabolizing enzymes as glutamate dehydrogenase I (GDH I), glutamate dehydrogenase II (GDH II), GABA transaminase (GABA-T), succinic semialdehyde dehydrogenase (SSADH) and succinic semialdehyde reductase (SSAR) were estimated. The following plants extracts from Acori graminei Rhizoma, Longnae Arillus, Gastrodiae Herba, Lycii Fructus, Ligusticum officinale, Ferula assafoetida, Corydalis Tuber, Eucommiae Cortex, Zizyphi spinosi Semen activated the activity of GDH I to more than 35%, and the following ones from Visci Ramulus, Ligusticum officinale, Myristicae Semen, Ferulae Resina, Scolopendrae Corpus, Corydalis Tuber, Eucommiae Cortex, Zizyphi spinosi Semen did that of GDH II.

Cosmetics are products used over long periods by the public, and their safety is very important. Contact dermatitis induced by cosmetics is the result of an inflammatory response of the skin to direct irritancy. The initial event that this inflammatory response is observed is the release of pro-inflammatory cytokines. In this study, the anti-inflammatory activities of extracts from Korean herb medicines were investigated using RAW264.7 macrophage. Among the fifty one extracts tested, the ethanol extracts from Biotae Orientalis Folium, Biotae Orientalis Folium (roasted), Cyperi Rhizoma, Nepetae Spica, Benincasae Semen, Dioscoreae Rhizoma, Dioscoreae Rhizoma (roasted), Mori Ramulus, Pini Ramulus and Alismatis Rhizoma reduced the cytotoxicity and inhibited the productions of Nitric oxide (NO) and cytokines such as interleukin (IL)-1${\beta}$, IL-6 and tumor necrosis factor (TNF)-${\alpha}$n lipopolysaccharide (LPS)-induced RAW264.7 macrophage. Additionally, they didn't induce the skin irritation when tested the human patch test. Overall, the result of this study suggests that the extracts of the ten Korean herb medicines are useful cosmetic agents for preventing the skin irritation.

In order to screen natural inhibitor of tyrosinase which catalyzes an enzymatic browning of some foods and in vivo synthesis of melanin, inhibitory effect of 129 edible plants and 15 chemical compounds on the in vivo melanin synthesis by mushroom tyrosinase was analyzed. Among leafy vegetables tested, radish bud, red chicory, Shepherd's purse and small green onion were found to have more than 50% tyrosinase inhibition effect in the descending order. Chinese radish and garlic in root vegetables, and nameko, shiitake and oyster mushroom in mushrooms, and teas showed also more than 50% inhibition effect. Among fruit vegetables tested, red pepper, Chinese quince and avocado were found to have more than 50% tyrosinase inhibition effect, while fruits generally showed low inhibitory effect. Medicinal plants which inhibit tyrosinase more than 50% were mume fructus>cinamomi ramulus>rubi fructus>mori cortex>biotae orientalis folium>puerariae radix, and herbs with more than 50% inhibitory effect were allspice>clove>mustard. In some chemical compounds tested, 4-hexylresorcinol, L-cysteine, glutathione, sodium bisulfite and kojic acid showed powerful inhibition effect on mushroom tyrosinase.
