Abalone, a marine organism inhabiting the west coast of Korea, has antioxidant and anti-inflammatory effects, and is a resource with potential to be used in various industries such as antibiotic development and cosmetic raw materials. In this study, we chose abalone among various marine lives on the west coast. Antibacterial peptide (AMP) was separated from abalone and its derivative Ab4-7 was identified and its physiological activity was studied. The treatment of Ab4-7 in inflammatory RAW 264.7 to check the anti-inflammatory efficacy nhibited inflammatory cytokines, TLR4, TNF-α, IL-1β, COX-2, and iNOS and increased mRNA manifestation of HO-1, genes related to antioxidants. Based on the strong antioxidant and anti-inflammatory effects of Ab4-7, the effects of Ab4-7 in the inflammatory RAW 264.7 cells were identified through RT-PCR, which regulates the gene Matrix Metalloproteinase (MMPs) that induces a variety of inflammatory skin diseases by engaging in the decomposition of the extrocellular matrix metalloproteinase (ECM). Taken together, it is concluded that Ab4-7 has a powerful anti-inflammatory and antioxidant effect and can be used as a functional material for various inflammatory skin disease treatments by controlling the genes associated with matrix metalloproteinase (MMPs).

The aim of this study was to compare the anti-inflammatory activities of Spirulina maxima treated with ultrasonication and water extraction process. S. maxima extracted via ultrasonication showed low cytotoxicity (16.90%) in a normal human cell line, CCD-986sk. Especially, S. maxima ultrasonication extract showed the highest DPPH radical scavenging activities (46.82%) compared to water extract (31.30%) at $100^{\circ}C$. In addition, ultrasonication extract showed a high amount of flavonoids (21.60 mg/g) and total phenols ($8.36{\mu}g/mL$). Nitric oxide production by 1.0 mg/mL of S. maxima ultrasonication extract strongly inhibited ($1.3770{\mu}M$), whereas water extract showed lower inhibition ($1.5784{\mu}M$). TNF-${\alpha}$ and IL-6 cytokines were effectively inhibited by 1.0 mg/mL of S. maxima ultrasonication extract, which shows strong antioxidant activities. Based on these results, it can be concluded that the ultrasonication process increase anti-inflammatory activity of S. maxima extract.

The antioxidant and anti-inflammatory effects of active ingredients in cosmetics are very important. The effects are closely related to the prevention of skin aging. Among medicinal plants, Bletilla striata Reichenbach fil. has well-known pharmacological activity. Extracted samples were prepared using sequential fractionation of ethyl acetate, butanol, and water. The antioxidant effect of the fractions was confirmed by DPPH and ABTS+ radical scavenging. Among the various fractions of B. striata Reichenbach fil., ethyl acetate was associated with a reduction in nitric oxide production, which was induced by LPS (lipopolysaccharide) treatment in a dose-dependent manner. In addition, the production of iNOS (inducible nitric oxide synthase) and COX-2 (cyclooxygenase-2), which are upstream regulators of nitric oxide production, was also inhibited. Thus, the ethyl acetate fraction of B. striata Reichenbach fil. appears to be a potential active ingredient for use in cosmetics.

탁리소독음이 옹저에 있어 항염증 효과를 살펴보고자 NO의 농도, 세포 생존도, iNOS의 표현 및 $TNF-{\alpha}$의 농도를 실험한 결과, NO의 농도는 현저하게 감소하였고 세포 생존도는 탁리소독음에 의하여 영향을 받지 않았으며 iNOS의 표현에 있어서 iNOS의 고도가 현저하게 낮아졌고 $TNF-{\alpha}$의 농도는 현저한 변화가 없었다. 이상을 살펴볼 때 탁리소독음이 옹저에 있어 항염증효과가 있음을 알 수 있었다. 또한 탁리소독음이 충분히 대식세포의 역할을 대신하며 이 이외의 신호경로가 염증기전에 작용한 것으로 생각되며 많은 연구가 요할 것으로 사료된다.

This study was to demonstrate the anti-inflammation effect using extracts derived from fusion-fermentation to add the function of Araliae Continentalis Radix (fACR). Since there are limitations to the use of ACR, available strains were selected through fermentation using lactobacillus strains, and the increases in total amount of polyphenols and amino acids was confirmed through comparison with Hot Water Extract of ACR. To determine the anti-inflammatory effect of the fACR was measure cytokine inflammation associated with arthritis, the arthritis when cartilage destruction is accompanied mainly MMP-9 activity was confirmed to evaluate the inhibition effect. These results show that fermentation using lactobacillus increases major biological activities and inflammatory response-restraining effects of ACR. This study is expected to be a basis for studying the preventive effect of fACR on arthritis.

we are investigated the anti-inflammatory effects of Safflower and Mother wort Ethanol Complex Extracts(SEC) on lipopolysaccharide (LPS)-activated RAW 264.7 cells. The results demonstrated that pretreatment of SEC(500㎍/mL) significantly reduced NO production by suppressing iNOS protein expression in LPS-stimulated cells. Anti-inflammatory effects by Safflower and Mother wort Ethanol Complex Extracts were observed in the following. Safflower and Mother wort Ethanol Complex Extracts inhibited the translocation of NF-κB from the cytosol to the nucleus via the suppression of IκB-α phosphorylation and also inhibited LPS-stimulated NF-κB transcriptional activity. These findings suggest that Safflower and Mother wort Ethanol Complex Extracts exert anti-inflammatory actions and help to elucidate the mechanisms underlying the potential therapeutic values of Safflower and Mother wort Ethanol Complex Extracts. Therefore, Safflower and Mother wort Ethanol Complex Extracts could be regarded as a potential source of natural anti-inflammatory agents.

Acer tegmentosum Maxim (ATM) is known as traditional medicine for treatment of hepatic disorders such as hepatitis, related-inflammatory disease, and hepatic cancer. In this study, we evaluated the antioxidant and anti-inflammatory effects of ATM extracted with $80^{\circ}C$ water or 95% ethanol. Antioxidant activities of ATM extracts were measured based on DPPH and ABTS radical scavenging activities, total polyphenolic compound contents, and ferric reducing antioxidant power. The anti-inflammatory effects of ATM extract were assayed on release of nitric oxide, tumor necrosis factor $(TNF)-{\alpha}$, and interferon $(IFN)-{\gamma}$ from lipopolysaccharide (LPS)-induced macrophages. In these experiments, 95% ethanol extract of ATM showed stronger antioxidant and anti-inflammatory effects than water extract. Therefore, we determined the effects of ATM ethanol extract on an animal model of sepsis. Seven days oral gavage of ATM ethanol extract followed by LPS stimulation reduced the protein levels of $TNF-{\alpha}$ and $IFN-{\gamma}$ in serum as well as mRNA levels of $TNF-{\alpha}$ and interleukin-6 in intestinal epithelial cells. In addition, ATM ethanol extract reduced DNA damage in mouse lymphocytes. These results indicate that ATM extract has strong antioxidant and anti-inflammatory in vitro and in vivo effects and may be developed as a potential food material for prevention of inflammatory diseases.
