  • 두드러기는 가려움으로 인해 발생되는 피부상의 상해질환으로써 나이에 관계없이 높은 발병률을 가지고 있다. 한방에서는 만성두드러기의 원인 중 하나로 비위(脾胃)의 습열(濕熱)을 말한다. 소갈탕(升葛湯)은 보비익기(補脾益氣)의 효능을 가지고 있어 비위(脾胃)의 습열(濕熱)을 없애는데 사용되어 왔다. 최근 연구에 의하면 소갈탕(升葛湯)은 재발성 홍반성 두드러기를 효과적으로 억제하는 효능이 있다고 밝혀졌으나 소갈탕(升葛湯)의 항염증효과에 대한 메커니즘은 명백하지 않은바 이에 우리는 BV2세포에 있어서 NO농도, iNOS의 발현정도, $PGE_2$의 생산, 세포생존도, COx-2, $IL-1{\beta}$, IL-12, $TNF-{\alpha}$의 발현을 조사하였다. 그 결과 소갈탕(升葛湯)은 NO, $PGE_2$의 생산을 현저하게 억제하며 iNOS, COX-2, $IL-1{\beta}$, IL-12, $TNF-{\alpha}$ 역시 감소하였고 세포생존도에는 영향을 주지 않는 것으로 나타났다. 이상(以上)을 살펴볼 때 소갈탕(升葛湯은 항염증 효과를 가지고 있음을 알 수 있다.

  • Panax ginseng is a medicinal herb that is used worldwide. Its medicinal effects are primarily attributable to ginsenosides located in the root, leaf, seed, and flower. The flower buds of Panax ginseng (FBPG) are rich in various bioactive ginsenosides, which exert immunomodulatory and anti-inflammatory activities. The aim of the present study was to assess the effect of 18 ginsenosides isolated from steamed FBPG on the transcriptional activity of NF-${\kappa}B$ and the expression of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$)-stimulated target genes in liver-derived cell lines. Noticeably, the ginsenosides $Rk_3$ and $Rs_4$ exerted the strongest activity, inhibiting NF-${\kappa}B$ in a dose-dependent manner. SF and $Rg_6$ also showed moderately inhibitory effects. Furthermore, these four compounds inhibited the TNF-${\alpha}$-induced expression of IL8, CXCL1, iNOS, and ICAM1 genes. Consequently, ginsenosides purified from steamed FBPG have therapeutic potential in TNF-${\alpha}$-mediated diseases such as chronic hepatic inflammation.

  • Yeonguemjiri-tang(連芩止痢湯, YGT) exhibits potent anti-inflammatory activity in widely intestine disease, but its mechanism undisclosed. To elucidate the molecular mechanisms of YGT on pharmacological and biochemical actions in inflammation, we examined the effect of YGT on pro-inflammatory mediators in phorbol 12-myristate 13-acetate (PMA) plus A23187-induced mast cell and lipopolysaccharide (LPS)-stimulated macrophages. The investigation focused on whether YGT inhibited pro-inflammatory cytokines such as interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in PMA plus A23187-induced HMC-1 cells and inflammatory madiators such as nitric oxide (NO), TNF-${\alpha}$, IL-6, iNOS, COX-2 in LPS-stimulated RAW 264.7 cells. We found that YGT inhibited LPS-induced NO, TNF-${\alpha}$ and IL-6 productions as well as the expressions of iNOS and COX-2. These results suggest that YGT has inhibitory effects on mast cell-mediated and macrophage-mediated inflammation.

  • The present study describes the preliminary evaluation of the anti-inflammatory activities of Artemisia fukudo extracts. The 80% ethanol extract of A. fukudo was sequentially fractionated with n-hexane, dichloromethane, ethylacetate, and butanol. In order to effectively screen for anti-inflammatory agents, we first examined the extracts’ inhibitory effects on the production of pro-inflammatory cytokines activated with lipopolysaccharide. Moreover, we examined the inhibitory effects of the A. fukudo extracts on pro-inflammatory factors (NO, iNOS, COX-2, and $PGE_{2}$) in murine macrophage RAW 264.7 cells. The protein levels were determined by immunoblotting. Of the sequential solvent fractions, the n-hexane and dichloromethane fractions inhibited the mRNA expression of pro-inflammatory cytokines (TNF-${\alpha}$, IL-$1{\beta}$, and IL-6), production of NO and $PGE_{2}$, and the protein levels of iNOS and COX-2. These results suggest that A. fukudo may have signifIcant effects on inflammatory factors, and may be a potential anti-inflammatory therapeutic plant.

  • The objective of this study was to evaluate the skin inflammation effects of three herb mixture extracts, Ligularia fischeri, Solidago virga-aurea and Aruncus dioicus, which are from Ullung island in Korea. Regulatory mechanisms of cytokines and nitric oxide (NO) are involved in the immunological activity of Raw 264.7 cells. Tested cells were pretreated with 70% acetone extracts of Ligularia fischeri, Solidago virga-aurea and Aruncus dioicus (LSA-A) and further cultured for an appropriated time after lipopolyssacharide (LPS) addition. During the entire experimental period, 1, 10, and 100 ${\mu}g/ml$ of LSA-A had no cytotoxicity. In these concentrations, LSA-A inhibited the production of NO and prostaglandin $E_2$ ($PGE_2$), tumor necorsis factor-a (TNF-a), interleukin-1${\beta}$ (IL-1${\beta}$), interleukin-6 (IL-6) expression of inducible NO synthase (iNOS), and cyclooxygenase-2 (COX-2). LSA-A showed a 60% $PGE_2$ inhibition rate at 100 ${\mu}g/ml$. iNOS and COX-2 inhibition activities were 54%, and 65% at 100 ${\mu}g/ml$, respectively. In addition, LSA-A extract reduced the release of inflammatory cytokines including TNF-a, IL-1${\beta}$ and IL-6. These results suggest that LSA-A may have significant effects on inflammatory factors, and may be a potential anti-inflammatory therapeutic agent.

  • Camellia japonica oil (CJ oil) has been used traditionally in East Asia to nourish and soothe the skin as well as help restore the elasticity of skin. CJ oil has also been used on all types of bleeding instances. However, little is known about its anti-inflammatory effects. Therefore, the anti-inflammatory effects of CJ oil and its mechanisms of action were investigated. CJ oil inhibited LPS-induced production of NO, $PGE_2$, and TNF-${\alpha}$ in RAW264.7 cells. In addition, expression of COX-2 and iNOS genes was reduced. To evaluate the mechanism of the anti-inflammatory activity of CJ oil, LPS-induced activation of AP-1 and NF-${\kappa}B$ promoters was found to be significantly reduced by CJ oil. LPS-induced phosphorylation of $I{\kappa}B{\alpha}$, ERK, p38, and JNK was also attenuated. Our results indicate that CJ oil exerts anti-inflammatory effects by downregulating the expression of iNOS and COX-2 genes through inhibition of NF-${\kappa}B$ and AP-1 signaling.

  • This study was designed to investigate the anti-inflammatory effect of oyster shell extract on the production of pro-inflammatory factors [NO, reactive oxygen species (ROS), nuclear factor-kappa B (NF-${\kappa}B$), inducible nitric oxide synthase (iNOS) and cycloxygenase-2 (COX-2)] and pro-inflammatory cytokines [Interleukin-$1{\beta}$ (IL-$1{\beta}$), Interleukin-6 (IL-6) and TNF-${\alpha}$] in the lipopolysaccharide (LPS)-stimulated Raw 264.7 cells. Cell viability, as measured by the MTT assay, showed that oyster shell extract had no significant cytotoxicity in Raw 264.7 cells. The treatment with oyster shell extract decreased the generation of intracellular reactive oxygen species dose dependently and increased antioxidant enzyme activities, such as SOD, catalase, GSH-px in LPS-stimulated macrophage cells. Oyster shell extract significantly suppressed the production of NO and also decreased the expressions of iNOS, COX-2 and NF-${\kappa}B$. Additionally, oyster shell extract significantly inhibited the production of IL-$1{\beta}$, IL-6, and TNF-${\alpha}$ in LPS-stimulated Raw 264.7 cells. Thus, these results showed that the oyster shell extract had an anti-inflammatory effect on LPS-stimulated Raw 264.7 cells.
