This study was performed to investigate the influence of dietray food from the three CHinese medicinal herbs(Mugwort, Dried organge peel and Duchung) on lipi d metabolism in rats. Male rats of Sprague-Dawley strain were divided into four dietary groups(Cellulose (CL), Mugwort(MW), Dried organge peel9OP), Duchung(DC)) after three weeks of hyperlipidemic dieting and were fed ad libitum each of the experimental diets for six weeks. The fiber sources of the experimental diets were prepared by drying and milling mugwort, orange peel, duchung and cellulose. Each of the Fiber sources was mixed into the diet to achieve 10g% levels of total dietary fiber. Levels of apparent fat absorption exhibited a significant decrease in the MW and DC groups. The OP group also showed a decreasing trend, but to a lesser extent. The levels of serum total lipid were not significantly different among the four experimental groups. Total serum cholesterol levels were significantly lower in the OP grop that in both the CM and MW group. Serum TG and LDL-cholesterol levels were significantly higher in the DL group than other groups. Serum HDL-cholesterol levels were significantly levels were significantly lower in the CL group than in the other groups. Total lipid and total cholesterol in liver were significantly higher in the CL group than in the other groups. Total lipid and total cholesterol in feces displayed a significantly increase in the MW and DC groups when compared with the CL group. The OP group also showed an increase compared to the CL group.

Objectives : We performed this study to understand the molecular basis of the antitumor effect of Saussurea lappa, Pharbitis nil, Plantago asiatica and Taraxacum mongolicum, which have been used for cancer treatment in Korean traditional medicine. Design: We analyzed, the effect of these medicinal herbs on proliferation and apoptosis of tumor cells and its association with gene expression, We performed semi-quantitative reverse transcription-polymerase chain reaction(RT-PCR) analysis of cell cycle- and apoptosis-related genes using a gastric cancer cell line AGS. Results : Cell counting assay and $[^3H]thymidine$ uptake analysis showed that Saussurea lappa and Pharbitis nil strongly inhibit cell proliferation of AGS in a dose-dependent manner. Interestingly, gene espression assay revealed that mRNA espression levels of c-Jun, c-Fos, c-Myc, and Cyclin D1 were markedly decreased by Saussurea lappa and Pharbitis nil. Furthermore, Saussurea lappa was identified to activate expression of the p53 tumor suppressor and its downstream effector $p21^{Wafl}$, which leads to $G_1$ cell cycle arrest and apoptosis. These observations suggest that the anticancer effect of Saussurea lappa and Pharbitis nil might be associated with their regulatory capability of tumor-related gene expression.

This study was carried out to investigate the effect of ethanolic extract Salicornia herbacea (SHEE) on melanogenesis and mechanism. The SHEE on ${\alpha}$-melanocyte stimulating hormone (${\alpha}$-MSH) induces melanogenesis in B16F10 melanoma cells. The effect of SHEE remarkably decreased protein expression of tyrosinase and tyrosinase relate protein (TRP)-2 increased extracellular signal related kinase (ERK) on ${\alpha}$-MSH 100 nM induced melanogenesis on B16F10 melanoma cells at dose-dependent manner. It has been reported that the activation of ERK reduce melanin synthesis by down-regulating micro-phthalmia-associated transcription fator (MITF). These results sugggest that possibility of extracted korean medicinal herbs as a functional ingredient for whitening cosmetic formula.

DF formula is comprised of three traditional herbs, Ephedra intermedia, Rheum palmatum and Lithospermum erythrorhizon, and locally used for treating of the metabolic diseases, such as obesity and diabetes in Korea. We tried to optimize the extraction conditions of two major components, (-)-ephedrine and (+)-pseudoephedrine, in DF formula using response surface methodology with Box-Behnken design (BBD). The experimental conditions with 70% for EtOH concentrations, 4.8 hour for extraction hours and 8.7 times for the solvent to material ratio were suggested for the optimized extraction of DF formula with the highest amounts of (-)-ephedrine and (+)-pseudoephedrine in the designed model.

P-methoxycinnamic acid and 3,4,5-trimethoxycinnamic acid are the compounds found in Polygalae Radix, the root of Polygala tenuifolia Willdenow, and have been reported to have hepatoprotective and anti-neurodegenerative effects. On the other hand, there are no reports of their effects on gastric lesions. This study examined the inhibitory effects of cinnamic acids, including p-methoxycinnamic acid, 3,4,5-trimethoxycinnamic acid, and 8 compounds (cinnamic acid, 2-(trifluoromethyl) cinnamic acid, 3-(trifluoromethyl) cinnamic acid, trans-4-(trifluoromethyl) cinnamic acid, 4-(dimethylamino) cinnamic acid, 3,4-(methylenedioxy) cinnamic acid and 3,4-dihydroxycinnamic acid), which were selected based on their presence in medicinal herbs and molecular weight, against gastric lesions. Animal models were used to confirm the protective effects on acute gastritis caused by the administration of HCl/EtOH. Gastric acid inhibition was examined by an acid-neutralizing test and the proton pump ($H^+/K^+$-ATPase) inhibiting activity. In addition, antioxidant tests were performed and the gastric emptying rate was determined. The results showed that cinnamic acid, p-methoxycinnamic acid, and 3,4,5-trimethoxycinnamic acid had an inhibitory effect on gastric lesions.

Objectives: Systems biology is a novel subject in the field of life science that aims at a systems' level understanding of biological systems. Because of the significant progress in high-throughput technologies and molecular biology, systems biology occupies an important place in research during the post-genome era. Methods: The characteristics of systems biology and its applicability to traditional medicine research have been discussed from three points of view: data and databases, network analysis and inference, and modeling and systems prediction. Results: The existing databases are mostly associated with medicinal herbs and their activities, but new databases reflecting clinical situations and platforms to extract, visualize and analyze data easily need to be constructed. Network pharmacology is a key element of systems biology, so addressing the multi-component, multi-target aspect of pharmacology is important. Studies of network pharmacology highlight the drug target network and network target. Mathematical modeling and simulation are just in their infancy, but mathematical modeling of dynamic biological processes is a central aspect of systems biology. Computational simulations allow structured systems and their functional properties to be understood and the effects of herbal medicines in clinical situations to be predicted. Conclusion: Systems biology based on a holistic approach is a pivotal research methodology for understanding the mechanisms of traditional medicine. If systems biology is to be incorporated into traditional medicine, computational technologies and holistic insights need to be integrated.

Pharmacological inhibition of interleukin-12 (IL-12) production may be a therapeutic strategy for preventing the development and progression of disease in experimental models of autoimmunity. In this study, the effects of myricetin, a naturally occurring flavonoid present in fruits, vegetables and medicinal herbs, on the production of IL-12 were investigated in mouse macrophages stimulated with lipopolysaccharide (LPS). Myricetin significantly inhibited the LPS­induced IL-12 production from both primary macrophages and the RAW264.7 monocytic cell-line in a dose-dependent manner. The effect of myricetin on IL-12 gene promoter activation was analyzed by transfecting RAW264.7 cells with IL-12 gene promoter/luciferase constructs. The repressive effect was mapped to a region in the IL-12 gene promoter containing a binding site for NF-${\kappa}B$. Furthermore, activation of macrophages by LPS resulted in markedly enhanced binding activity to the NF-${\kappa}B$ site, which significantly decreased upon addition of myricetin, indicating that myricetin inhibited IL-12 production in LPS-activated macrophages via the down­regulation of NF-KB binding activity.

Objective : This paper is aimed at suggesting further tasks by checking and rectifying the errors of the ancieut Chinese-vernacular Korean translations of Park Ji-won(朴趾源)'s "Kumryosocho". Method : In order to correct the wrongly transcribed "Kumryosocho" was contrasted with the original "Xiangzubiji(香祖筆記)", of which the part is "Kumryosocho". And then the errors and mistakes are discovered in published ancient Chinese-to-vernacular Korean translations. Result : In the course of checking the existing translations of "Kumryosocho", this paper identified the following types of errors. 1. Errors attributable to unfamiliar names of medicinal herbs 2. Errors due to the unfamiliarity with the names of diseases or symptoms in Traditional Koreau Medicine(TKM). 3. Errors committed in hand transcription. These types of errors were committed as well in translating jargons routinely used in TKM books. To the surprise, the errors above have been repeated even in the latest version of its translation. This means that the medicine-related materials by Silhak scholars, including "Kumryosocho", were placed at a dead zone of the research between Chinese classic scholars and TKM scholars. Conclusion : To minimize errors and mistakes, it is needed to activate the cooperative work of heterogeneous experts in two academic fields.
