Traditional medicines (TM) in Korea, China, and Japan share most of the theories and therapeutic tools, but there are also differences due to their unique histories and cultures. Here, we aim to identify the differences in the utilization of TM theory between three countries by analyzing herb usage data in terms of the related traditional theories. Herb usage data of each country was collected from "Investigation of Korean medicine use and herbal medicine consumption survey" (Korea), "Analytical report on circulation of key Chinese medicinal materials" (China), and "Survey report on raw material crude drug usage" (Japan). Fifty five herbs with sixty features belonging to five theoretical categories (four properties, five tastes, targeting meridians, treatment strategies, and herbal parts) were selected and analyzed. Weight Sum Model (WSM) and Network-Based Group Features (NBGF) were used to compare the theoretical characteristics of TM between three countries. For the statistical evaluation, we developed and applied Herb Set Enrichment Analysis (HSEA) for WSM and NBGF results. HSEA for WSM results revealed the kidney meridian were targeted more in Korea than Japan, while the spleen meridian were targeted more in Japan than Korea. Herbs with sour taste were used more in Japan than China. HSEA for NBGF results found that NBGF including warm, neutral, sweet, and tonifying features were more dominant in Korea and than Japan, while NBGF including cold, bitter, heat-clearing features were more dominant in Japan than the others. These results suggest that TM in Korea, China, and Japan have unique aspects of practice patterns and theoretical utilization.

Artemisia species are widely used as food ingredients and raw material in traditional medicine. However, to date, the secondary metabolites of Artemisia gmelinii Weber ex Stechm. have not been sufficiently investigated. The secondary metabolites of A. gmelinii, which was collected from representative regions in Chungbuk, Gangwon, and Gyeongbuk, were analyzed using ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTof MS) combined with an unsupervised principal component analysis (PCA) multivariate analysis. In the loading scatter plot of PCA, significant changes in metabolites were observed between the regions, ten metabolites (3: 5-O-caffeoylquinic acid, 4: 4-O-caffeoylquinic acid, 8: trans-melilotoside, 12: quercetin 3-O-hexoside, 15: 3,4-O-dicaffeoylquinic acid, 17: 3,5-O-dicaffeoylquinic acid, 18: 4,5-O-dicaffeoylquinic acid, 19: syringaldehyde, 20: caffeoylquinic acid derivative, and 23: icariside II) were evaluated as key markers among twenty-five identified metabolites. Interestingly, the contents of the identified marker significantly differed between the three groups. This is the first study to report the presence of marker metabolites and their correlating geographical cultivation in A. gmelinii.

We performed the present study to investigate whether Rehmannia glutinosa Libosch (RG) extracts (RGX) and Eleutherococcus senticosus Max (ES) extracts (ESX) play any roles in bone metabolism. We examined cellular activities of bone cells by measurement of osteoblastic cell viability, osteoprotegerin (OPG) secretion from osteoblasts, osteoclastogenesis, and osteoclastic activity. There is no cytotoxicity from osteoblasts after treatment with RGX and ESX. The secretion of OPG from the osteoblasts showed marked increases after treatment with RGX and ESX. In addition, RGX and ESX treatment decreased the number of tartrate-resistant acid phosphatase-positive multinucleated cells and the resorption areas. RGX and ESX, when mixed at optimal ratios, induced synergic effects, in vitro. OPB, which showed synergic effects, is the extract of natural ingredients RG and ES mixed at a raw material weight ratio of 4 : 1. It can be suspected that extracts of RG and ES mixtures contains active ingredients involved in bone tissue metabolism and may be effective in improving osteoporosis.

Using the spray pyrolysis process, nano-sized cobalt oxide powder with average particle size below 50 nm was prepared from cobalt chloride solution. The influences of the raw material solution on the properties of the powder formed examined. When the concentration of Co was low(20 g/L), the average particle size of the powder formed was roughly 20 nm, and the cohesion between these particles was significantly strong. When the concentration of Co increased to 100 g/L, the droplets nearly failed to exist in circular form and reflected a severely divided form. Furthermore, the average size of the particles formed was roughly 40 nm, and the particles reflected a polygonal form. When the solution was increased to nearly saturation level (Co at 200 g/L), the particle size distribution reflected significant unevenness due to severe droplet division while the surface also reflected significant unevenness. Furthermore, the average size of the particles formed increased significantly to 70 nm. The results of XRD analysis showed that the strength of the peaks reflected very little change when the concentration of Co was increased from 20 g/L to 50 g/L. Alternatively, when the concentration was increased to 100 g/L, the strength of the peaks increased compared to when the concentration was 50 g/L. However, when the concentration was increased to 200 g/L, the strength of the peaks failed to reflect significant change compared to when the concentration was 100 g/L. The specific surface area dramatically decreased by 30 % when the concentration of Co was increased from 20 g/L to 50 g/L. Alternatively, when the concentration of Co the solution increased to 100 g/L, the specific surface area decreased by roughly 15 %. Furthermore, when the concentration of Co was increased to nearly saturation level(200 g/L), the specific surface area decreased by roughly 35%.

Lagerstroemia ovalifolia Teijsm. & Binn. (LO) (crape myrtle) has reportedly been used as traditional herbal medicine (THM) in Java, Indonesia. Our previous study revealed that the LO leaf extract (LOLE) exerted anti-inflammatory effects on lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. Based on this finding, the current study aimed to evaluate the protective effects of LOLE in a mouse model of LPS-induced acute lung injury (ALI). The results showed that treatment with LPS enhanced the inflammatory cell influx into the lungs and increased the number of macrophages and the secretion of the inflammatory cytokines in the bronchoalveolar lavage fluid (BALF) of mice. However, these effects were notably abrogated with LOLE pretreatment. Furthermore, the increase of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2) and monocyte chemoattractant protein-1 (MCP-1) expression in the lung tissues of mice with ALI was also reversed by LOLE. In addition, LOLE significantly suppressed the LPS-induced activation of the MAPK/NF-κB signaling pathway and led to heme oxygenase-1 (HO-1) induction in the lungs. Additionally, in vitro experiments showed that LOLE enhanced the expression of HO-1 in RAW264.7 macrophages. The aforementioned findings collectively indicate that LOLE exerts an ameliorative effect on inflammatory response in the airway of ALI mice.

We have examined the effect of water extract of Phellinus linteus, a raw material of Korean traditional herbal medicine, on the induction of HL-60 cell differentiation. The proliferation of HL-60 cell was inhibited dose-dependently by treatment with various doses of P. linteus extract. It also caused a significant change in NBT reduction (7.5 times). The expression of CD11b and CD14 was increased in the cells treated with the extract, especially in those arrested at G0/G1 stage, which suggested that some components in P. Linteus extract induced HL-60 cell differentiation to granulocytic and monocyte lineages. Moreover, the expression levels of $p21^{WAF1/CIP}$ and $p27^{KIP}$ were up-regulated during HL-60 cell differentiation induced by P. Linteus extract. These results together suggest that P. Linteus extract contains potential HL-60 cell differentiation agents.
