A recent study reported that Pleurotus ostreatus has the potential to be used as a ${\beta}-glucan-based$ cream for supportive complementary therapy of atopic dermatitis. KH054 is a new herbal prescription consisting of P. ostreatus and Panax ginseng. The effects of atopic dermatitis-induced materials on the expression of cytokine genes in human monocytes (THP-1, EoL- 1) have been examined. Some reports demonstrated that P. ginseng augments the activity of natural killer cells, which plays an important role in innate immunity against infection and tumor development. Monocyte chemotactic protein 1 (MCP-1), interleukin (IL)-6, and IL-8 have important roles in mediating the infiltration of various cells into the skin of atopic dermatitis and psoriasis. The present study investigated whether KH054 on induced IL-6, IL-8, and MCP-1 secretion by house dust mite (Dermatophagoides pteronissinus) in THP-1 (human acute monocytic leukemia) and EoL-1(Human eosinophilic leukemia) cell. D. pteronissinus functions in the pathogenesis of allergic diseases, including atopic dermatitis and asthma. The inhibitory effect of KH054 on the induction of IL-6, IL-8, and MCP-1 secretion by D. pteronissinus extract in THP-1 and EoL-1 cells was examined. KH054 potently suppressed the elevated production of IL-6 and IL-8 induced by D. pteronissinus treatment in THP-1 and EoL-1 cells. Based on the present results, KH054 may be useful for developing functional foods to treat atopic dermatitis.

본 연구에서는 lipopolysaccharide(LPS)로 자극한 마우스 대식세포인 RAW 264.7 세포에서 가락진두발 에탄올 추출물(CNYEE)의 항염증 효과를 알아보기 위하여 nitric oxide(NO)와 pro-inflammatory cytokine의 분비량을 확인하였다. 그 결과 CNYEE 모든 농도에서 LPS만을 처리한 대조군과 비교하였을 때 유의성 있게 NO와 pro-inflammatory cytokine의 분비량을 저해하였으며, 특히 $100{\mu}g/mL$ 농도에서는 IL-6의 분비량을 70% 이상 억제하였고, TNF-${\alpha}$ 및 IL-$1{\beta}$의 분비량은 50% 이상의 억제 효과를 나타내었다. CNYEE에 의한 염증매개물질의 분비 감소가 전사인자인 nuclear factor-${\kappa}B$(NF-${\kappa}B$)의 핵 내 전이 pathway를 저해함으로써 나타난 결과인지 확인하기 위하여 iNOS, COX-2 및 NF-${\kappa}B$ p65의 단백질 발현량을 관찰한 결과, 비교적 낮은 농도인 $50{\mu}g/mL$에서 40% 이상의 저해능을 보인 것으로 보아 NO와 cytokine의 분비 억제 결과가 NF-${\kappa}B$ pathway를 저해함으로써 나타난 것임을 유추할 수 있었다. 또한 LPS에 의해 증가한 mitogen-activated protein kinases의 인산화를 확인한 결과, CNYEE 처리에 의해 농도 의존적으로 유의성 있게 저해되었다. 이러한 결과를 종합해볼 때 가락진두발 에탄올 추출물은 염증매개물질의 분비를 효과적으로 저해함으로써 추후 천연물로서 염증 치료제의 개발이 가능할 것으로 생각한다.

To elucidate the composition of bumblebee (Bomb us terrestris) venom (BBV) and the anti-inflammatory effect of BBV. The major components of BBV by LC chromatography and SDS-PAGE were identified. The production of nitric oxide (NO) and proinflammatory cytokines was examined by lipopolysaccharide (LPS) in a macrophage cell line, RAW 264.7 cells, with BBV. BBV inhibits LPS-induced NO in a dose dependent manner. We also found that BBV inhibits proinflammatory cytokine, tumor necrosis factor (TNF)-${\alpha}$ and interleukin (IL)-6 production. These findings mean that BBV can be used in controlling macrophages mediated inflammation related disease. Additional studies on the pharmacological aspects of the individual components of BBV are recommended for future trials.

This study investigated anti-inflammatory and antibacterial activities of Sedum takesimense ethanolic extract, and 3 isolated compounds. To confirm anti-inflammatory and anti-acne activities, a nitric oxide (NO) inhibition assay, pro-inflammatory factor (TNF-α, IL-1β, and IL-8) inhibition assays, and minimum inhibitory concentration (MIC) tests were performed. The 3 isolated compounds were identified as 4,6-di-O-galloylarbutin (OGA), 2,4,6-tri-O-galloyl-glucose (OGG), and 1,2,4,6-tetra-O-galloyl-β-glucose (TOGG). The ethanolic extract and isolated compounds (OGA, OGG, TOGG) effectively inhibited production of NO and pro-inflammatory cytokines (TNF-α, IL-1β, and IL-8). Furthermore, OGG and TOGG exhibited MIC values toward Cutibacterium acnes of 12.5 ㎍/mL and 3.2 ㎍/mL, respectively. These results suggest that S. takesimense extract exerts an anti-inflammatory effect on LPS-induced RAW264.7 cells, and an antibacterial efficacy against C. acnes.

CHP showed safety in cytotoxicity and toxicity of liver and kidney for logn time administration. CHP increased the DPPH and ABTS radical scavenging activity. CHP showed significant inhibitory effect on reactive oxygen species (ROS), and showed inhibitory effect on nitiric oxide(NO) compared to control group. CHP decreased cytokine IL-6 production significantly, and decreased IL-1β and TNF-α compared to control group. CHP decreased body and organ weitht, intake food, and glucose levels compared to control group. CHP decreased total cholesterol and triglyceride significantly, and decreased LDL-cholesterol levels and increased HDL-cholesterol levels compared to control group. CHP decreased atherogenic index and cardiac risk factor significantly. CHP increased serum insulin and GLP-1 compared to control group. In histologic examination, lipophagy in the liver and aorta decreased in CHP treated mice and the cell was regular and boundary of vessel wall was clear compared to control group. These results suggest that CHP is effective in antioxidation activity and treatment and prevention of hyperlipidemia, atherosclerosis, diabetes, ischemic heart disease, stroke and other cardiocerebrovascular disease.

Primary pro-inflammatory cytokines are a trio: tumor necrosis- $\alpha$ (TNF-$\alpha$), interleukine-$\beta$ (IL-$\beta$), and interleukine-6 (IL-6). These cytokines initiate and regulate the acute-phase inflammatory response during infection, trauma, or stress and appear to play an important role in the immune process. Nitric oxide (NO) is a multi-functional mediator, which plays an important role in regulating various biological functions in vivo. NO production by inducible nitric oxide synthase (iNOS) in macrophages is essential for the defense mechanisms against microorganisms and tumor cells. However, over-expression of iNOS by various stimuli, resulting in over-production of NO, contributes to the pathogenesis of septic shock and some inflammatory and auto-immune disease. Solvent fractions of sage ( Salvia officinalis L.), which is cultivated in Jeju-Do, was assayed for their effects on TNF-$\alpha$ and IL-6 production in LPS-stimulated RAW 264.7 macrophages. Hexane and ethylacetate (EtOAc) fraction of sage inhibited the protein and mRNA expression of TNF-$\alpha$ and IL-6 in LPS stimulated RAW 264.7 cells at the concentration of 100 $\mu\textrm{g}$/$m\ell$. Also, incubation of RAW 264.7 cells with the fraction of hexane or EtOAc (50 $\mu\textrm{g}$/$m\ell$) inhibited the LPS induced nitrite accumulation and the LPS/IFN-${\gamma}$ induced iNOS protein. And this inhibition of iNOS protein is concordant with the inhibition of iNOS mRNA expression. Above results suggest that extract of sage may have anti-inflammatory activity through the inhibition of pro-inflammatory cytokines (TNF-$\alpha$, IL-1$\beta$, IL-6), iNOS and NO.

Flavonoid myricetin, usually found in tea and medicinal plants, has antioxidant and anti-inflammatory effects. Our objectives in this study were to verify the effects of myricetin on periodontal ligament fibroblasts (PDLFs) under inflammatory conditions and to observe its effects on osteoclast generation and on cytokine expression in RAW264.7 cells. To determine the effects of myricetin on PDLFs, we examined the expression and activity of proteolytic enzymes, including MMP-1, MMP-2, and MMP-8, which all play an important role in chronic periodontitis. We observed the effects of myricetin on intracellular signal transduction to verify the molecular mechanism involved. By measuring the formation of TRAP-positive multinucleated cells and the expression and activity of MMP-8, we were able to assess the effects of myricetin on osteoclast generation. In addition, by measuring the secretion of IL-6 and NO, we could evaluate the effects of myricetin on inflammatory mediators. We found that Myricetin had no effect on the viability of the PDLFs in the presence of inflammation, but it did decrease both the expression of MMP-1 and MMP-8 and the enzyme activity of MMP-2 and MMP-8 in these fibroblasts. Myricetin also decreased the lipopolysaccharide-stimulated phosphorylation of JNK, p38 signaling, IKKB, AKT, and p65RelA in the PDLFs. In the RAW264.7 cells, myricetin inhibited both the expression and the activity of MMP-8. Furthermore, Myricetin not only suppressed the generation of LPS-stimulated osteoclasts, but it also slightly inhibited LPS-stimulated degradation of IkB and decreased the release of LPS-induced IL-6 and NO. These findings suggest that myricetin alleviates the tissue-destructive processes that occur during periodontal inflammation.
