Objectives : In recent years, many studies have been widely researching anti-inflammation effect of various medicinal plants. $Cinnamomi$ $Cortex$ was not enough in researching of the anti-inflammation. Moreover, there is no comparative study about extraction methods. Therefore, we investigated the inhibitory effects of $Cinnamomi$ $Cortex$ pharmacopuncture by EtOH and Hot water extraction on Nitric oxide(NO), Prostaglandin E2(PGE2) production, Cyclooxygenase(COX)-2, inducible NOS(iNOS) expression and extracellular signal regulate kinase(ERK)1/2 phosphorylation in lipopolysaccharide(LPS) induced RAW 264.7 macrophage cell. Methods : $Cinnamomi$ $Cortex$ was extracted by EtOH and Hot water. RAW 264.7 macrophage cell viability was measured by MTT assay. Effect of $Cinnamomi$ $Cortex$ pharmacopuncture on NO and PGE2 production in LPS induced macrophages was accessed by Griess assay and enzyme-linked immunospecific assay(ELISA), respectively. Inhibition effect on COX-2, iNOS expression and ERK1/2 phosphorylation was examined by Immunoblotting assay. Results : 1. Cytotoxic effect of $Cinnamomi$ $Cortex$ pharmacopuncture by Hot water extraction in RAW 264.7 macrophages was not appeared, except $3125{\mu}g/m{\ell}$. And cytotoxic effect was not appeared in EtOH extraction method. 2. $Cinnamomi$ $Cortex$ pharmacopuncture by EtOH and Hot water extraction inhibited NO production in LPS induced macrophages significantly. 3. $Cinnamomi$ $Cortex$ pharmacopuncture by EtOH and Hot water extraction inhibited PGE2 production in LPS induced macrophages significantly. 4. $Cinnamomi$ $Cortex$ pharmacopuncture by EtOH and Hot water extraction inhibited COX-2, iNOS expression in LPS induced macrophages. Especially, it has been confirmed that COX-2, iNOS expression were effectively inhibited in Hot water extraction. 5. $Cinnamomi$ $Cortex$ pharmacopuncture by EtOH and Hot water extraction inhibited ERK1/2 phosphorylation in LPS induced macrophages. Especially, it has been confirmed that ERK1/2 phosphorylation was effectively inhibited in Hot water extraction. Conclusions : According to the results, $Cinnamomi$ $Cortex$ pharmacopuncture suppresses NO, PGE2 production, COX-2, iNOS expression and ERK1/2 phosphorylation in LPS induced macrophages. It has a potential for treating various inflammatory diseases, and Hot water extraction method could be used more extensively than EtOH extraction method.

Backgrounds: Multidisciplinary approaches including surgery, chemotherapy, and radiation therapy are currently being performed to target various cancers in Western Medicine. However, some cancers still remain difficult to battle, which has long attracted many scientists for the discovery of new agents to fight cancers. Ginseng is one of the herbs used in Oriental Medicine including Korea, China and Japan. We have further investigated ginseng for its anticancer effect. Objective: This is a comprehensive review summary of anticancer effect of ginseng and ginsenoids as a possible agent for future cancer treatment. Methods: Data were retrieved from two web sites; www.pubmed.com and www.riss.kr, and authorized texts concerning anticancer effects of ginseng. From collected data, information on anticancer effect of ginseng was thoroughly sorted, restructured, then assessed. Results: Panax Ginseng C.A. Meyer belongs to Araliaceae Panax family, a perennial prairie plant with its root known as Ginseng Radix. Ginseng induces anticancer effect through cell cycle arrest, acceleration of apoptosis, anti-angiogenesis, and suppression of metastasis. Anticancer effect of ginseng may be due to single compound or multi-compound actions. Many studies report involvement of immune mechanisms of cytokines, Natural Killer (NK) cells, macrophages and some antibodies in enhancing anticancer effect of ginseng. In near future, possibility of applying these mechanisms into clinical trials is convinced. There were some important findings on saponin in ginsenoids in reviewing for this article; First, eradication of metastatic tumors were influenced by macrophage activation. Second, suppression of malignant melanoma cell metastasis to lung were induced by macrophage and NK cell activation in spleen with red ginseng acidic polysaccharide (RGAP). Third, final metabolites of M1, M4 had exerted anticancer effect of ginseng. Conclusion: Unknown anticancer mechanisms of ginseng have been studied for many years up until now. Ginseng is comprised of multiple bio-chemical compounds that create complex pharmaceutical interactions. Therefore, for its proper usage and safe prescription, studies on different types of ginseng and patients' susceptibility to ginseng according to their constitution and stages of the disease should be further pursued. More efforts are needed to understand the anticancer mechanisms of ginseng as well.

Dangyuja (Citrus grandis Osbeck) is a native plant growing only on Jeju Island in Korea. In this study, antiinflammatory effect of dangyuja leaves on a murine macrophage cell line was investigated. RAW 264.7 murine macrophage cells were stimulated with lipopolysaccharide (LPS, $1{\mu}g/mL$) to induce expression of pro-inflammatory markers [interleukin (IL)-6 and inducible nitric oxide synthase (iNOS)]. The crude extract (80% MeOH Ex.) and solvent fractions (hexane, $CHCl_3$, EtOAc, BuOH, and $H_2O$ Ex.) were obtained from dangyuja leaves. The $CHCl_3$ fraction inhibited the nitric oxide (NO) and IL-6 production in a dose-dependent manner. Also, the $CHCl_3$ fraction inhibited mRNA expression and protein levels of iNOS in a dose-dependent manner. Furthermore, the $CHCl_3$ fraction inhibited LPS-induced nuclear factor (NF)-${\kappa}B$ activation and phosphorylation of mitogen-activated protein kinases (MAPKs: ERK, JNK, and p38). These results suggest that dangyuja leaves may inhibit LPS-induced production of inflammatory markers by blocking NF-${\kappa}B$ and MAPKs signaling in RAW 264.7 cells.

The peel from seven types of citrus was extracted with 80% methanol, and their phenolic compound content, oxygen radical absorbance capacity (ORAC), inhibitory activities of nitric oxide (NO), and reactive oxygen species (ROS) production induced by LPS and t-BHP in LPS-activated RAW 264.7 cells were measured. Total phenolic content was high in Yungkyool, Cheonhyehyang, and Jinkyool (30.6, 30.2, and 28.2 mg GAE/g, respectively), while total flavonoid content was high in Yungkyool and Jinkyool (30.3 and 25.5 mg RE/g, respectively). ORAC was the highest at 1,076 mM TE/g in Yungkyool, followed by Cheonhyehyang (1,012), Jinkyool (984), and Hallabong (914). High inhibitory activity against NO production was shown in Cheonhyehyang, Yungkyool, and Jinkyool with $IC_{50}$ values of 215.3, 259.2, and 328.9 ${\mu}g/mL$, respectively. LPS-induced ROS production was inhibited by 16.4% and 12.8% in Hallabong and Jinkyool, while t-BHP-induced ROS production was inhibited by 28.7%, 26.1%, and 26.6% in Jinkyool, Hallabong, and Cheonhyehyang, respectively. Correlation coefficients between total phenolic, total flavonoid content, and ORAC were 0.884 and 0.855. Inhibitory activity against NO production showed higher correlation with total phenolic content than total flavonoid content. It was concluded that citrus peels had potent antioxidant activities and could be used as natural antioxidants in the food and pharmaceutical industries.

Purpose : To evaluate the chemokine expression in children with a non-productive cough. Materials and Methods : Six children with a non-productive cough who visited Yeungnam University Hospital were evaluated for the mRNA expression of interferon-${\gamma}$-inducible protein 10(IP-10), macrophage cationic protein 1 and 3 (MCP-1, 3), interleukin (IL)-8, regulated upon activation in normal T cells expressed and secreted (RANTES), eotaxin and growth-related oncogene-${\alpha}$ (Gro-${\alpha}$) using the reverse transcription polymerase chain reaction. Results : The chemokines IP-10 and MCP-3 were expressed in all samples. The chemokine RANTES was expressed in five cases, and IL-8 was expressed in three among them. However, eotaxin, Gro-${\alpha}$ and MCP-1 were not expressed at all. The expression of chemokine MCP-3, RANTES and IL-8 were suppressed after the resolution of coughing in just one available case. Conclusion : The chemokines MCP-3, RANTES and IL-8 may contribute to airway inflammation in children with a non-productive cough, whereas IP-10 is of secondary importance in this condition.

Calcium concentration in the bone resorption lacunae is high and is in the mM concentration range. Both osteoblast and osteoclast have calcium sensing receptor in the cell surface, suggesting the regulatory role of high extracellular calcium in bone metabolism. In vitro, high extracellular calcium stimulated osteoclastogenesis in coculture of mouse osteoblasts and bone marrow cells. Therefore we examined the genes that were commonly regulated by both high extracellular calcium and $1,25(OH)_2vitaminD_3(VD3)$ by using mouse oligo 11 K gene chip. In the presence of 10 mM $[Ca^{2+}]e$ or 10 nM VD3, mouse calvarial osteoblasts and bone marrow cells were co-cultured for 4 days when tartrate resistant acid phosphatase-positive multinucleated cells start to appear. Of 11,000 genes examined, the genes commonly regulated both by high extracellular calcium and by VD3 were as follows; 1) the expression of genes which were osteoclast differentiation markers or were associated with osteoclastogenesis were up-regulated both by high extracellular calcium and by VD3; trap, mmp9, car2, ctsk, ckb, atp6b2, tm7sf4, rab7, 2) several chemokine and chemokine receptor genes such as sdf1, scya2, scyb5, scya6, scya8, scya9, and ccr1 were up-regulated both by high extracellular calcium and by VD3, 3) the genes such as mmp1b, mmp3 and c3 which possibly stimulate bone resorption by osteoclast, were commonly up-regulated, 4) the gene such as c1q and msr2 which were related with macrophage function, were commonly down-regulated, 5) the genes which possibly stimulate osteoblast differentiation and/or mineralization of extracellular matrix, were commonly down-regulated; slc8a1, admr, plod2, lox, fosb, 6) the genes which possibly suppress osteoblast differentiation and/or mineralization of extracellular matrix, were commonly up-regulated; s100a4, npr3, mme, 7) the genes such as calponin 1 and tgfbi which possibly suppress osteoblast differentiation and/or mineralization of extracellular matrix, were up-regulated by high extracellular calcium but were down-regulated by VD3. These results suggest that in coculture condition, both high extracellular calcium and VD3 commonly induce osteoclastogenesis but suppress osteoblast differentiation/mineralization by regulating the expression of related genes.

To elucidate the immuno-stimulatory activity of traditional fermented vinegar, six kinds of crude polysaccharides were isolated from traditional fermented vinegars manufactured with different raw materials in domestic or foreign countries, after which their chemical properties and immuno-stimulatory activities were evaluated. Of the six samples, three kinds of crude polysaccharides prepared from Korean brown rice vinegar (KBV-0), Japanese brown rice vinegar (JBV-0), and Korean persimmon vinegar (KPV-0) showed higher yields and interleukin (IL)-6 production by macrophages and were thus selected for further study. Anti-complementary activities of KBV-0, KPV-0, and JBV-0 increased dose-dependently. KBV-0 and KPV-0 showed higher anti-complementary activities ($ITCH_{50}$ 62 and 65%) than JBV-0 at $1,000{\mu}g/mL$. KBV-0, KPV-0, and JBV-0 did not affect growth of peritoneal macrophages at a dose of 1.6 to $1,000{\mu}g/mL$, where as they significantly augmented production of IL-6, IL-12, and TNF-${\alpha}$ in a dose-dependent manner. However, immuno-stimulatory activity of KPV-0 was the most potent among the tested polysaccharides. These results suggest that Korean fermented vinegars contain selected polysaccharides that confer immuno-stimulatory activities beneficial to human health.

Objectives : The purpose of this study was verification of the restoration ability effect of Danggwisusan extract(DG) in wound induced Rat. Methods : It needed to make a scar(around $2{\times}2cm^2$) on the top of the fascia in the back of the rats and then the rats were divided into 4groups(n=6). Control was not treated at all, where as DG was orally medicated DG, Terra was percutaneously applied Terramycin, and DG + Terra was both orally medicated DG and percutaneously applied Terramycin per day for three weeks. Results : 93% or higher cell viability was observed in all tested groups from 1, 10, $100{\mu}g/m{\ell}$ in RAW 264.7cells. The DG decreased NO and cytokine production activity dose dependently. The production of IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ were decreased by 46%, 46% and 40% in DG treated $100{\mu}g/m{\ell}$. The size of wound was significantly decreasing in DG, Terra, DG + Terra. WBC was significantly reduced in DG and DG + Terra. Monocyte was significantly reduced in DG, Terra and DG + Terra. Neutrophil was also reduced in DG, DG + Terra but not meaningless. The mRNA expression of MMP-1 was significantly reduced in Terra, MMP-2 was significantly reduced in DG, Terra, DG + Terra, and MMP-9 was significantly reduced in DG + Terra. Conclusions : According to the results, we thought that DG showed anti-inflammatory activities on the RAW 264.7cells in mouse macrophage and in adult rat wound. Moreover, the progress of recovery was found visually, heamatologically, genetically and histopathologically. In conclusion, it could be thought that DG has effect on the treating of wound.
