Objectives : This study was carried out to know the anti-osteroarthritic effects of Bangkibokryeong-tang(Fanjifuling-tang(BBT)) on the papain-induced osteoarthritis C57BL/10 mouse. Methods : Osteoarthritis was induced by injection of papain(6 ${\mu}l$) into knee joint of mouse. Osteoarthritic mice were divided into 4 groups(normal, control, joins(R), BBT). The injection did not fit the normal group. A week later, after the injection of papain, control group was taken normal saline 200 ${\mu}l$, positive control group was taken joins(R)(100 mg/kg), treated group was taken extract of Bangkibokryeong-tang(Fanjifuling-tang(BBT))(400 mg/kg). After then, we examined hepatotoxicity, nephrotoxicity, inflammation cytokines, expression of inflammation factor mRNA, hemotology, histology through the micro CT-arthrography, and etc. Results : 1. Hepatotoxicity and nephrotoxicity have not expressed. 2. The levels of IL-$1{\beta}$, TNF-${\alpha}$, IL-6, MCP-1, Thromboxane B2, Leukotriene B4, Prostaglandin E2 in serum were significantly decreased. 3. In hematology, the levels of neutrophils and monocytes were significantly decreased. 4. The expression of inflammation factor mRNA like TNF-${\alpha}$ and IL-6, COX-2, iNOS-II were significantly inhibited. 5. In micro CT-arthrography, cartilage volume was less decreased. 6. The degree of osteoarthritis induced damage of joint of BBT group is low in histopathologic observation(hematoxylin&eosin(H&E), Safranin-O). Conclusions : According to this study, BBT has effect of anti-osteoarthritis. Further clinical research for the cartilage protective effect is necessary.

Objectives: Inflammatory mediators, such as nitric oxide (NO), prostaglandin E2 ($PGE_2$) and pro-inflammatory cytokines, TNF-${\alpha}$ and IL-$1{\beta}$ playa critical role in inflammatory immune response. Therefore, intervention of inflammatory mediator production promises therapeutic benefit for treatment of many chronic inflammatory diseases, such as allergic asthma, rheumatoid arthritis, multiple sclerosis, septic shock and neurodegenerative diseases. In this study, the pharmacological effects of the flower MeOH extract Panax notoginseng (Notoginseng Flos; NF) on inflammation were investigated to address potential therapeutic or toxic effects. Methods: RA W264.7 cells were treated with different concentrations of NF methanol (NF-M) extract in the presence or absence of LPS ($1{\mu}g/m{\ell}$). Results: NF-M extract significantly inhibited LPS-induced production of NO, $PGE_2$ and pro-inflammatory cytokines, TNF-${\alpha}$ and IL-$1{\beta}$ in a dose-dependent manner. In addition, NF-M extract suppressed mRNA expressions and protein levels of iNOS, COX-2 and pro-inflammatory cytokines in LPS-stimulated RA W264.7 cells. Conclusion: These results indicated that NF-M extract inhibits LPS-induced production of inflammatory mediators in macrophages and demonstrated that NF-M extract possesses anti-inflammatory properties in vitro.

In order to determine the functional benefits of Cordyceps militaris in the immune system, we examined the immunomodulatory activities of C. militaris using an immunocompromised C57BL/6 mice, mouse spleen cells, RAW 264.7 macrophage cells, and A549 lung carcinoma cells. Mice were injected intraperitioneally with an immunosuppressive drug, cyclophosphamide, and then administered orally with 30, 100 and 300 mg/kg of 50% ethanol extract of C. militaris (CME 30, CME 100 and CME 300) for 14 days. CME increased splenocyte proliferation and natural killer (NK) cell activity compared to 3% hydroxypropyl methylcellulose-treated control mice. CME also increased the production of Th1 cytokines, IL-2 and TNF-${\alpha}$ in spleen cells isolated from CME-injected mice and in vitro, which suggested the enhanced cellular immunity in response to CME. CME also increased splenocyte proliferation, NK cell activity, and IL-2 and TNF-${\alpha}$ production compared to 1 ${\mu}M$ methotrexate-treated spleen cells in vitro. We examined whether C. militaris regulates the production of inflammatory mediators in LPS-stimulated RAW 264.7 cells. CME inhibited LPS-induced NO production and iNOS expression in a dose dependent manner, while COX-2 expression was remained unchanged. In addition, CME also has free radical scavenging activity, indicating its antioxidant activity. These results indicate that C. militaris enhances immune activity by promoting immune cell proliferation and cytokine production.

In this study, the inflammation of ethanol extracts from Caryopteris incana (CI) and fermented C. incana (FCI) on induced to lipopolysaccharide with Raw 264.7 cell was tested. The composition profile of L. plantarum was changed by fermentation, and confirmed by HPLC analysis. We performed the 3-[4,5-dimethylthiazol]-2-yl]-2,5-diphenyltetrazolium bromide assay to evaluate the toxicity of CI and FCI extracts. In cell viability, cell toxicity was not shown at 5, 10 and $15{\mu}g/mL$ of CI extracts and 10, 20, 30 and $40{\mu}g/mL$ of FCI extracts. The results of inducible nitric oxide synthase and cyclooxygenase-2 protein production were confirmed to be inhibitory in a concentration-dependent manner, respectively. Additionally, protein expression of nitric oxide and prostaglandin $E_2$ by CI and FCI extracts were also inhibited in a concentration-dependent manner. In the result of pro-inflammatory cytokine, $15{\mu}g/mL$ concentration of CI extracts was showed tumar necrosis factor $(TNF)-{\alpha}$ (57.3%), interleukin (IL)-6 (35.2%), and $IL-1{\beta}$ (48.0%), respectively. And $40{\mu}g/mL$ of FCI extracts was showed $TNF-{\alpha}$ (34.6%), IL-6 (32.1%), and $IL-1{\beta}$ (30.0%), respectively. These results suggest that FCI extracts showed better effect of anti-inflammatory than CI extracts. Therefore, it was found that both CI and FCI can be used as an excellent material for the development of new anti-inflammatory resource.

Nitric oxide (NO) and prostagladins(PGs) produced by inducible nitric oxide synthase(iNOS) and cyclooxygenase(COX-2) are known as inflammatory mediator. Modulation of these enzymes, induced by many stimuli(LPS, IFN-gamma, TNF-alpha, phorbol ester, etc), is a potent strategy as treatment of inflammatory diseases. Treatment of murine macrophage RAW 264.7 cell line with indole compound(IND-6) markedly reduced lipopolysacchride(LPS) stimulated NO production in a concentration-related manner. (omitted)

Multiple lines of study have shown that Acanthopanax species have anti-oxidant and chemopreventive effect. However, the suitability of Acanthopanax sessilifloru fruit (Ogaza) as a functional food source remains to be investigated. Therefore, we have investigated the effect of Ogaza as an anti-oxidant and anti-inflammatory substance. The phenolic content of Ogaza is 56.1${\pm}$5.2 mg gallic acid equivalents (GAE) per 1 g of Ogaza. The 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid (ABTS) radical scavenging effects of Ogaza extract at 0.25, 0.5, 1, or 2 mg/mL were 34.0, 73.0, 194.3, or 339.7 $\mu g$/mL vitamin C equivalent antioxidnat capacity (VCEAC), respectively. Ogaza extract (1 or 2 mg/mL) inhibited LPS-induced TNF-$\alpha$ production (decrease of 22${\pm}$2% or 19${\pm}$6%, respectively). It also inhibited LPS-induced IL-6 production (decrease of 18${\pm}$2% or 24${\pm}$3%, respectively). In addition, Ogaza extract (0.25, 0.5, 1, or 2 mg/mL) inhibited COX-2 luciferase activity (decrease of 80${\pm}$1%, 83.${\pm}$7%, 96${\pm}$4%, or 98${\pm}$2%, respectively). Overall, these results indicated that Ogaza is promising as a functional food source due to its antioxidant and anti-inflammatory effects.

Codium fragile has been traditionally used in oriental medicine to treat enterobiasis, dropsy, and dysuria, and it has been shown to possess many biological properties. Atopic dermatitis (AD) is one of the types of skin inflammation and barrier disruption, which leads to chronic inflammatory skin diseases. In the current investigation, the protective effects of C. fragile extract (CFE) on anti-inflammation and skin barrier improvement were investigated. In LPS-stimulated RAW 264.7 cells, nitric oxide generation and the expression levels of interleukin (IL)-1β, IL-4, IL-6, iNOS, COX-2, and tumor necrosis factor-alpha (TNF)-α were reduced by CFE. CFE also inhibited the phosphorylation of NF-κB-p65, ERK, p-38, and JNK. Additionally, CFE showed inhibitory activity on TSLP and IL-4 expression in HaCaT cells stimulated with TNF-α/interferon- gamma (IFN-γ). Enhanced expression of factors related to skin barrier function, FLG, IVL, and LOR, was confirmed. These findings implied that CFE may be used as a therapeutic agent against AD due to its skin barrier-strengthening and anti-inflammatory activities, which are derived from natural marine products.

Earth worm (Eisenia andrei) and clam worm (Perinereis linea) have been used as anti-bacterial and anti-inflammatory agent. However, it is unclear how they exerted their physiological effects in macrophages. In this experiment, the anti-inflammatory and antioxidant effects of clam worm extract (CWE) and earth worm extract (EWE) in RAW264.7 cells were examined by measuring MDA, catalase, SOD, GSH-Px and inflammatory cytokines (nitric oxide, iNOS, interleukin-$1{\beta}$ and tumor necrosis factor-${\alpha}$). Treatment with CWE significantly increased the activities of catalase, SOD and GSH-Px in RAW264.7 cells and decreased the level of MDA. Interestingly, treatment with CWE induced more activities of SOD than EWE. In addition, CWE decreased NO production, iNOS, COX-2, TNF-${\alpha}$ and IL-$1{\beta}$ in RAW264.7. The EWE also decreased NO production and iNOS, but increased COX-2 and IL-$1{\beta}$ suggesting that CWE could be better resources for anti-inflammatory and antioxidant agent than EWE. Taken together, these results indicate that CWE has the potential as a natural antioxidant and a therapeutic for inflammation-related diseases.
