Objectives : We studied the ISP(information strategy plan) of oasis spanning 5 years. From this study we aimed at total road map to upgrade the service systematically and to carry out the related projects. If we do it as road map, oasis will be the core infra service contributing to the improvement of TKM(traditional korean medicine) research capability. Methods : We carried out 3 step ISP method composed of environmental analysis, current status analysis and future plan. We used paper, report and trend analysis document as base materials and did the survey to get opinions from users and TKM experts. We limited this study to drawing the conceptual design of oasis. Results : From environmental analysis we knew that China and USA built up the largest TM databases. We did the survey to get the activation ways of oasis. And we did the benchmarking on the advanced services through current status analysis. Finally we determined 'maximize the research value based the open TKM knowledge infra' as oasis' vision. And we designed oasis' future system which is composed of service layer, application layer and contents layer. Conclusion : First TKM related documents, research materials, researcher information and standards are merged to elevate the TKM information level. Concretely large scale TKM information infra project such as TKM information classification code development, TKM library network building and CAM research information offering are carried out at the same time.

In order to search for anti-HSV agents from natural complex products, we extended the number of specimens. Both methanol extract and boiling water extract of the natural complex products were screened to detect anti-HSV activity by MTT assay. Anti-HSV activities of thirteen natural complex products extracted by methanol and boiling water were screened. Three of 13 natural complex products extracted by methanol showed efficacy against HSV. Natural complex products showing anti-HSV activities as methanol extracts were No.3, 6, 11 and their Sl were 323.809, 2811.041 and 708.20. As water boiling extracts, No.8 and No.11 have displayed Sl of 16.45 and 60.39 respectively. Especially anti-HSV activities of natural complex products extracted by methanol No.6 was stronger than other ones.

Insampaedoksan (IS) is the decoction of medicinal herbs, which was commonly used for anti-inflammatory and anti-pyretic in the Korean traditional medicine (KTM). Several studies on improving efficiency or searching new efficiency by fermenting traditional herbal medicines are recently in progress. The bioconversion has been conducted on IS using various bacteria. Liquiritin, ferulic acid, hesperidin, liquiritigenin, and glycyrrhizin in IS before and after fermented IS were simultaneously analyzed. These compounds were qualitatively analyzed and quantitatively analyzed using the HPLC-DAD system. The identifications of liquiritin, ferulic acid, hesperidin, liquiritigenin and glycyrrhizin were achieved by comparing the HPLC retention time ($R_t$) and the UV absorption of five pure compounds in the IS. As a result, the increased constituents were identified to be liquiritin, liquiritigenin and glycyrrhizin, while the decreased constituent was ferulic acid and the constituent of hesperidin was similar to before and after fermentation. Insampeadock-san fermented by Lactobacillus plantarum KFRI 144 exhibited the most remarkable changes in all of fermentation.

The effect of herbal medicine on glutamate mediated neurotoxicity was studied in mouse neurons in primary culture. Immature cerebral cortex neurons (ED14) were maintained for up to 2 weeks in vitro, and we investigated the expression pattern of neuron differentiation and cytotoxicity of cell death, including LDH activity. Neuronal maturation initiated on day 7 and the susceptibility to glutamate-induced cell death was highly sensitive on Day 11 (Fig. 1). Thus, the exposure of the neurons to glutamate caused a dose$(0.1mM{\sim}1mM)$ and time$(4h{\sim}24h)$-dependent neurotoxicity(Fig. 4). Glutamate-induced neurodegeneration was prevented by Shipchondaebotang(SD), Yollyounggobondan(YG), Yugmijihwangwon(YJ) and the death of neurons exposed to glutamate was blocked by the NMDA receptor antagonist MK-801 (Fig. 5).

Objective : Academies or societies of Korean Medicine have their journals. Those Journals usually follow guidlines for authors of Journal of KOMS(Korean oriental medical society). However, altough academies or societies of Korean Medicine are branches of KOMS, their guidlines for authors of journal are different form KOMS's. Method : We compared guidlines for authors in academies or societies of Korean Medicine which journals is listed in NRF(National Research Foundation of Korea). Result : They have 78.9% coincidence in guidlines for authors of journal, 68.4% in url adress and 57.9% in both books and chapter. Conclusion : Academies or societies of Korean Medicine might comply with KIOM in guidlines for authors of their journal because they are brabches of KIOM. In addition, these days, scholars try to make journal DB, journal referaence DB, ontology and so on so journals of KIOM and journals of Korean Medicine academies might be agreed especially in guidlines for authors.

The zebrafish (Danio rerio) is an established model organism for several pathophysiological conditions which are related to human diseases. In this study, we tested the preventive effect of eight herbal extracts, which show the inhibitory effect of advanced glycation end products (AGEs) or aldose reductase (AR) in our previous study, on high glucose (HG)-induced retinal vessel dilation in larval zebrafish and analyzed the change of hyaloid vasculature. HG-induced zebrafish hyaloid vasculatures were significantly increased in the thickness compared to untreated zebrafish (P<0.001, n=6~10). Eight herbal extracts were found to have significant retinal vessel dilation on the inhibitory activity. Particularly, Brandisia hancei (twigs and fruits), Castanopsis orthacantha (leaves and twigs), Litsea japonica (leaves and twigs), Spenceria ramalana (whole plant), and Synedrella nodiflora (leaves and stems) showed potent inhibitory activity against retinal vessel dilation in HG-induced larval zebrafish.

Objectives : The aim of this study was to investigate the hepatoprotective effect of Soshiho-tang (SSH) in mouse primary liver cells against hydrogen peroxide ($H_2O_2$)-induced oxidative stress. We also elucidated the molecular mechanism of hepatoprotective effect by SSH. Methods : Cell viability, level of ALT, AST and LDH, intracellular ROS level, mRNA expression and activity of antioxidant enzymes were used to evaluate hepatoprotection of SSH against $H_2O_2$. Target gene expressions were analyzed by real-time PCR. Results : Pre-treatment with SSH for 1 hour prevented cytotoxicity against $H_2O_2$. $H_2O_2$-induced ROS level decreased under SSH pre-treatment. mRNA expression of GPx and SOD increased in SSH-treated cells. In addition, HSP72 and HSP40 gene expression were elevated under SSH-treatment. Conclusions : These results indicate that SSH protects mouse primary liver cells from $H_2O_2$-induced oxidative injury. This hepatoprotective activity of SSH is mediated by decreasing intracellular ROS and increasing antioxidant enzyme expression (GPx and SOD) and stress response protein (HSP72 and HSP40).

Objectives : Electroacupuncture is widely used because of its diverse curative influence. However, its electrical safety is not guaranteed when applied on the human body. Therefore, in this study, we did research on the corrosiveness of electroacupuncture when applied on the body fluid. Methods : We did research using acupuncture needles which were made of STS304 or STS316 and which were coated or not coated in silicone. They were 0.25 mm in diameter and 40 mm in length. We immersed them to the depth of about 1cm in Hank's Solution and gave a stimulus in 120 Hz for 60 minutes. Then, we measured the pH of Hank's solution and mass of needles and observed their shape. Results : Acupuncture needles which were made of STS304 corroded more easily than those which were made of STS316 when they were applied on the human body. Acupuncture needles which were coated in silicone corroded much more easily than those which were not coated in silicone when they were applied on the body fluid. Conclusions : In this study, we did research on the corrosiveness of electroacupuncture when it is applied on the body fluid using several acupuncture needles. We made a conclusion that when acupuncture needles were applied on the body fluid, the coated one made of STS304 corrodes more easily than the uncoated one made of STS316. We hope that additional further researches on the effect of the corrosiveness of an acupuncture needle will be carried out.

Objectives: Because of the characteristics of traditional Korean medicine, there are few overseas patents and SCI papers. Researchers are struggling to analyze the research trend using existing patent analysis system and paper analysis system. We aim to build up a web-based paper map analysis system for Traditional Korean Medicine to improve the situation. Methods: We studied the following three sub topics. First, we surveyed the research trend analysis method for traditional Korean medicine. Second, we designed a paper map analysis model and made the algorithm for it. Finally, the development of the paper map analysis system was conducted. Results: We developed a web-based paper map analysis system which has the three main functions being analysis chart, topology map and contour map. For the rich internet application, we used the flex development tool and java integrated development environment. Conclusion: We will provide our paper map analysis system in the OASIS through the minor changes to provide easy use. We hope that this system will be a useful tool to analyze the research trends for traditional Korean medicine.
