  • Ginseng berry(GB)는 진세노사이드Re를 함유하고 있으며, 항염, 피부 주름 완화의 기능을 가지고 있다. 본 연구에서는 Ginseng berry 아미노산 복합체의 TLC 분획 fraction 1, 2, 4를 확인하고 HPLC로 분석하였으며, fraction 1의 LC/MASS 분석을 통해 peptide (AP-1)를 동정하였다. AP-1에 의한 NO 생성 억제 효과를 조사하여 항염증 활성을 확인하였다. 또한 procollagen type I C-peptide (PIP) ELISA kit를 이용한 collagen 합성은 대조군 대비 50% 이상의 효과를 보였다. 이상의 결과로부터 진생베리 아미노산 복합체로부터 분리한 펩타이드는 항염과 주름개선 효능을 가진다고 사료되며, 향후 항염 및 항노화 화장품 원료로서의 이용 가능성을 보였다.

Methods : In order to confirm the anti-inflammatory activity of PGJT extract, the inhibitory effect on NO PGE2 production were evaluated and the expression level of iNOS, COX-2 and IL-6 mRNA were measured through qRT-PCR, Antioxidant activity was evaluated for radical scavenging activity using DPPH and ABTS, anti-aging activity was evaulated for collagenase, elastase, tyrosinase and L-DOPA oxidation inhibitory activity. Results : PGJT extract shows anti-inflammatory effect by inhibiting the production of NO and PGE2 by reducing the expression level of iNOS, COX-2 and IL-6 mRNA, antioxidant effect by increasing DPPH and ABTS scavenging abillity in a concentration dependent manner. In addition, the anti-aging effect was confirmed by inhibiting collagenase, elastase, tyrosinase production and L-DOPA oxidation.

  • Objectives : The Lycoris squamigera Maxim has been used traditionally for treatment of various diseases. However, the studies on the effect of Lycoris squamigera Maxim have not been carried out. In the present study, extract of Lycoris squamigera Maxim were tested for their anti-inflammatory and anti-oxidation effect. Methods : The anti-inflammatory effect of the various solvent extract was studied in lipopolysaccharide (lps)-treated mouse macrophage cells. RAW 264.7 cells were pre-incubated with Lycoris squamigera Maxim extracts for 4h and treated with $1\;{\mu}g/m{\ell}$ lps for 18h, and then the anti-inflammatory effects of extracts were determined. The anti-oxidation effect of extracts measured by DPPH method, reductive potential test, total phenolics test. Results : Extracted root's ethyl acetate layer showed a significant decrease in nitric oxide. And that layer (root's ethyl acetate extract) was showed decrease in TNF-${\alpha}$ concentration dependently. Separated from Root's ethyl acetate extract was fraction 1 has $0.1{\sim}5\;{\mu}M$ range, fraction 2 has $0.1{\sim}10\;{\mu}M$ range did not showed cytotoxicity. Anti-oxidation result as DPPH test showed the best was root ethyl acetate extract. Redusing power was made a comparison between fractions and standard. They were showed similar value. Fraction's total phenol containing result was better then standard. Conclusions : These results suggest that these extracts can be used as anti-inflammatory, anti-axidation materials.

  • The anti-inflammatory effect of the methanolic extracts of some medicinal plants was investigated on the hydrolysis of N-benzoylarginine-p-nitroanilide by trypsin in vitro, the writhing syndrome induced by acetic acid in mice, and the carrageenin-induced paw edema in rats. Among tested medicinal plants, the methanoilc extract of Angelica keiskei, Rosa rugosa and Cudrania tricuspidata showed significant inhibitory effect. And we also found that adenosine, isolated from A. keiskei was identified as one active components.

  • Objectives: The antitussive, expectorant, and anti-inflammatory effects of Mahwangyounpae-tang (MHYPT) aqueous extracts were observed in appropriate animal models of various respiratory disorders. Methods: MHYPT aqueous extracts were orally administered once a day for 11 days at dose levels of 400, 200, and 100 mg/kg. The effect of MHYPT was determined by comparing its antitussive effect with theobromine (TB), its expectorant effect with ambroxol (AM), and its anti-inflammatory effect with dexamethasone (DEXA). Results: MHYPT aqueous extracts (400 mg/kg) showed favorable antitussive effects comparable to those of TB (50 mg/kg) in the NH4OH-exposure coughing mouse model and expectorant effects comparable to those of AM (250 mg/kg) in the phenol red-secretion mouse model, but MHYPT (400 mg/kg) showed less anti-inflammatory activity compared to DEXA (1 mg/kg) in the xylene-induced acute inflammatory mouse ear model under the experimental conditions used. Conclusion: MHYPT aqueous extracts administered at dosage levels of 400, 200, and 100 mg/kg induced dose-dependent and favorable antitussive, expectorant, and anti-inflammatory activities that occurred by simultaneous modulation of the activity of mast cells and respiratory mucous production under the experimental conditions used in this study.

  • Honey used as conventional medicine has various pharmacological properties. In the honey and anti-inflammatory effect, Gelam honey and Manuka honey has been reported to exert anti-inflammatory activity. However, the anti-inflammatory effect and potential mechanisms of acacia honey (AH) are not well understood. In this study, we investigated anti-inflammatory activity and mechanism of action of AH in LPS-stimulated RAW264.7 cells. AH attenuated NO production through inhibition of iNOS expression in LPS-stimulated RAW264.7 cells. AH also decreased the expressions of $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ as pro-inflammatory cytokines, and MCP-1 expression as a pro-inflammatory chemokine. In the elucidation of the molecular mechanisms, AH decreased LPS-mediated $I{\kappa}B-{\alpha}$ degradation and subsequent nuclear accumulation of p65, which resulted in the inhibition of $NF-{\kappa}B$ activation in RAW264.7 cells. AH dose-dependently suppressed LPS-mediated phosphorylation of ERK1/2 and p38 in RAW264.7 cells. In addition, AH significantly inhibited ATF2 phosphorylation and nuclear accumulation of ATF2 in LPS-stimulated RAW264.7 cells. These results suggest that AH has an anti-inflammatory effect, inhibiting the production of pro-inflammatory mediators such as NO, iNOS, $TNF-{\alpha}$, IL-6, $IL-1{\beta}$ and MCP-1 via interruption of the $NF-{\kappa}B$ and MAPK/ATF2 signaling pathways.

  • Quercus mongolica (QM), which belongs to fagaceae, is one of the oak native to Korea. We evaluated the anti-inflammatory effect of branches extracted with 70% ethanol of QM (QM-B) and elucidated the potential signaling pathway in LPS-induced RAW264.7 cells. The QM-B showed anti-inflammatory activity through inhibition of NO production. The QM-B dose-dependently suppressed NO production by inhibiting iNOS, COX-2 and IL-6 expression in LPS-induced RAW264.7 cells. The QM-B inhibited the degradation and phosphorylation of IκB-α and NF-κB activation. The QM-B suppressed the phosphorylation of p38 and ERK1/2. Also, the QM-B increased HO-1 expression. These results suggested that QM-B may utilize anti-inflammatory activity by suppressing NF-κB and MAPK signaling pathway and inducing HO-1 expression indicated that the QM-B can be used as a natural anti-inflammatory drugs.

  • Zanthoxylum piperitum D.C. (ZP) peels has been used as a natural spice and herb medicine for hypertension reduction, for strokes, and for its anti-bacterial and anti-oxidant activity. However, the anti-inflammatory mechanisms employed by ZP have yet to be completely understood. In this study, we elucidate the anti-inflammatory mechanism of ZP in lipopolysaccharide (LPS)-induced RAW264.7 cells. We evaluated the effects of ZP in LPS-induced levels of inflammatory cytokines, prostaglandin E2 (PGE2), and caspase-1 using ELISA. The expression levels of inflammatory-related genes, including cyclooxygenase (COX)-2 and inducible nitric oxide synthase (iNOS), were assayed by Western blot analysis. We elucidated the effect of ZP on nuclear factor (NF)-κB activation by means of a luciferase activity assay. The findings of this study demonstrated that ZP inhibited the production of inflammatory cytokine and PGE2 and inhibited the increased levels of COX-2 and iNOS caused by LPS. Additionally, we showed that the anti-inflammatory effect of ZP arises by suppressing the activation of NF-κB and caspase-1 in LPS- induced RAW264.7 cells. These results provide novel insights into the pharmacological actions of ZP as a potential candidate for development of new drugs to treat inflammatory diseases.
