There are four types (So-Eum, So-Yang, Tae-Eum, Tae-Yang type) in Sasang constitutional medicine (SCM). In SCM, not only people but also herbal medicine are classified into four types. To date, there has been very little evidence of experimental classifications in SCM. So, we adapted Issatchenkia orientalis in two different culture media made from the herbal medicines for So-Eum and for So-Yang type. And the adapted Issatchenkia orientalis was inoculated into another eight culture media made from the herbal medicines for So-Eum and for So-Yang type. The mass reduction was measured every 12 hours for 2 days. Then, we analyzed the statistical differences of herbal medicines for So-Eum and for So-Yang type. There were significant differences of variables (R: rate of change in mass reduction, S: convex degree of mass reduction graph) in herbal medicine media for So-Eum (p=0.001, 0.001, respectively.). Suggesting a microbiological method of Sasang medicine research, current study may contribute to the establishment of experimental Sasang constitutional herbal medicine.

Objectives : This study investigated the hepatoprotective effects effects of Jageum-jung extract on alcohol-induced liver disease mice model. Methods : Alcoholic liver disease was induced by Ethanol in C57/BL6 male mice, which were fed Lieber-DeCarli liquid diet containing ethanol. Jageum-jung (100,200 and 300 mg/kg bw/day) were orally administered daily in the alcoholic fatty liver disease mice for 16 days. Results : The results indicate that Jageum-jung promotes hepatoprotective effects by significantly reducing aspartate transaminase (AST) and alanine transaminase (ALT) levels as indicators of liver damage in the serum. Furthermore, Jageum-jung decreased accumulation of triglyceride and total cholesterol, increased levels of superoxide dismutase (SOD) and glutathione (GSH) in the serum of the alcoholic fatty liver disease mice model. Additionally, it improved the serum alcohol dehydrogenase (ADH) activity. Conclusions : This study confirmed the anti-oxidative and hangover elimination effects of Jageum-jung extract, and suggests the possibility of using Jageum-jung to treat alcholic liver disease.

Angiogenesis, the formation of new blood vessels, is considered to be involved in many pathological symptoms such as diabetic retinopathy, arthritis, inflammation and solid tumour. In particular, it is thought that angiogenesis is critical for development and growth of solid tumour. Recent study shows that there is a highly significant association of microvessel density with overall survival and relapse-free survival in patients with breast tumour In this study, the inhibition effect of angiogenesis of traditional herbs used for the treatment of cancer was examined. It was found out that the extract of Agaricus blazei by boiling water is a possible inhibitor of angiogenesis. It inhibited normal developmental angiogenesis In the chorioallantoic membrane of chick embryos and also inhibited capillary-like tube formation by endotherial cells on matrigel in vitro. These results suggest that Agaricus blazei can be a potent angiogenesis inhibitor.

In Korea, China, and Japan, Paeonia lactiflora Pall (PL) has been used in the treatment of rheumatoid arthritis, hepatitis, and fever for more than 1200 years. It has been reported that PL has protective effects against $H_2O_2$-induced oxidative stress and LPS-induced liver inflammation. However cellular and molecular mechanism of PL protection against oxidative stress has not fully been elucidated. Here, we describe that the water-soluble extract of PL decreased $H_2O_2$-induced hepatotoxicity. This hepatoprotective effect of PL is reason to decrease the level of intracellular reactive oxygen species (ROS) and increase expression of heme oxygenase 1 (HO-1) and heat shock protein 72 (HSP72) which proteins are involved in protecting the cells from stress like as oxidative stress. We also elucidated that hepatoprotective effect of PL was abolished by knock down of HO-1 and HSP72 by siRNA. These results suggest that the increasing of HO-1 and HSP72 protein by PL treatment might be participated in hepatoprotective effect against oxidative stress such as $H_2O_2$.

A pulse measurement by tonometry provides useful information for diagnosis, including not only blood pressure and heart rate but also parameters for estimating a condition of the cardiovascular system. Currently, various pulse measurement devices based on the tonometry have been developed. A reliability of these devices is determined by a positioning technic between the sensor and the blood vessel and a controlling technique of the pressurization level. An angle of the sensor for the pulse measurement seems to be highly related with a measured signal, however, the objective studies for this issue have been not published. In this paper, the variation of the pulse signals by tonometry direction was experimentally assessed according to the angle of the sensor. In order for guaranteeing the repeatability of the experiment, we used a pulse generator device, which can generate human pulse signal by using silicon tube and fluid pump, and developed a structure for precise adjustment of the angle and the pressurization level of the sensor. The angle of the sensor was acquired by an inclinometer, which was attached at the opposite side of the sensor. As results, a coefficient of variation (CV) of a maximum amplitude (MA) of the pulse wave was largely increased over the angle range of $-9{\sim}9^{\circ}$. Furthermore, the changes of the pulse shape showed different aspects according to the sign of the angle tilted along the blood vessel. It is expected that the results of this study can be helpful for developing more precise pulse measurement devices based on the tonometry and applying in clinic.

Objectives: Several domestic search systems for research projects providing capabilities of searching and managing the research information based on metadata have been completed, although they cannot search projects for specific domains such as the Oriental Medicine field. Therefore, in this paper we propose an effective method for collecting and refining information of research projects in the oriental medicine field. We also design and implement a search management system based on the collected information. Methods: We chose three search elements and defined the collecting process for research projects. The collected information was refined to enhance the quality of results. Then, the search management system was implemented by Adobe Flex. Results: We were able to collect 1,688 research projects in the oriental medicine field. We also implemented the search management system, which provides the functionalities of search and management such as input, update, delete, spreadsheet import/export of R&D projects, user management and access control. Conclusions: The collected information and the search management system will be used in a project analysis system which will be constructed in the future. The project analysis system could help to analyze trends in oriental medicine research as well as construct a technical roadmap.

Objectives : Socheongryong-Tang (小靑龍湯, SCRT) has been widely used to treat respiratory disease. In this study, we investigated the protective effects of SCRT on hydrogen peroxide-induced hepatotoxicity. Methods : In the mouse primary liver cells, SCRT was pretreated for 1 h, and 1 mM $H_2O_2$ was treated to mouse primary liver cells. Cell viability was analyzed by using 3- 4,5-Dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide (MTT) assay. Also, the activity of AST, ALT and LDH were measured for the evaluation the protective effect of SCRT on $H_2O_2$-induced hepatotoxicity. Intracellular ROS level was analyzed by FACS. Results : SCRT pretreatment decreased $H_2O_2$-induced hepatotoxicity and intracellular ROS production. Pretreatment of SCRT significantly reduced the cytotoxic effect induced by $H_2O_2$, associated with reducing DNA fragmentation and AST, ALT, LDH activities. Conclusions : These results suggest that SCRT has protective effect against $H_2O_2$-induced hepatotoxicity.

Background: The plant Aster koraiensis has long been used as an ingredient in folk medicine. It has been reported that Aster koraiensis extract (AKE) prevents the progression of diabetes-induced retinopathy and nephropathy. However, although these beneficial effects of AKE on diabetes complications have been identified, the antidiabetic effects of AKE have not yet been completely investigated and quantified. In the present study, the glucose-lowering and antioxidant effects of aqueous and ethanolic AKEs were evaluated. Methods and Results: The glucose-lowering effects of aqueous and ethanolic (30%-, 50%-, and 80%-ethanol) AKEs were investigated via ${\alpha}$-glucosidase inhibitory assays. The mode of inhibition by AKEs on ${\alpha}$-glucosidase was identified through kinetic analysis. The total antioxidant capacity of each of the 4 AKEs was evaluated by assessing their conversion rate of $Cu^{2+}$ to $Cu^+$. The content of chlorogenic acid and 3,5-di-O-caffeoylquinic acid, the bioactive compounds in AKE, in each extract were analyzed by high performance liquid chromatography (HPLC). The AKEs showed potent ${\alpha}$-glucosidase inhibitory activity with mixed inhibition mode, and significant antioxidant capacity. Conclusions: These results of this study suggested that the AKEs tested had ${\alpha}$-glucosidase inhibitory and antioxidant effects. Among the extracts, the 80% ethanol extract showed the most significant ${\alpha}$-glucosidase inhibitory activity, with a half maximal inhibitory concentration ($IC_{50}$ value) of $1.65{\pm}0.36mg/m{\ell}$ and a half maximal effective concentration ($EC_{50}$ value) for its antioxidant activity of $0.42{\pm}0.10mg/m{\ell}$. It can therefore be used as a source of therapeutic agents to treat diabetes patients.
