  • The oxidative modification of low density lipoprotein(LDL) has been implicated in the development of atherosclerosis. Oxidized LDL are found in macrophage foam cell, and it can induce an macrophage proliferation in atherosclerotic plaque. In this study, we investigated the hypothesis that gamisoyosan(GS) may reduce atherosclerosis by lowering the oxidiazability of LDL, To achive this goal, we examined the effect of GS on LDL oxidation, nitric oxide production in mouse macrophage cell line, RAW264.7, and the effect of GS on cupuric sulfate-induced cytotoxicity, LDH release, and macrophage activity. GS inhibited the generation of oxidized LDL from native LDL in RAW264.7 cell culture, and decreased the release of LDH from cupric sulfate-stimulated RAW264.7 cell. In other experiments, GS activated RAW264.7 cell, and prolonged the survival time, and increased nitric oxide production in Raw 264.7 cells.

  • Objectives: The purpose of this study was to investigate the effects of Chaenomelis Fructus Herba Water Extract(CF) on the production of inflammatory mediators in RAW 264.7 cell mouse macrophages stimulated with LPS. Methods: We have not examined effect of CF on the cell viability of RAW 264.7 cell until we investigated effects of CF on LPS-induced productions of NO, Ca and various cytokines in RAW 264.7 cell. And when p-value is below 0.05, it is judged to have the significant difference statistically(P<0.05). Results: 1. CF increased the cell viability in the RAW 264.7 cell at the density of 25, 50, 100 and 200 ${\mu}g/ml$. 2. CF inhibited significantly increasing the production of NO in LPS-induced RAW 264.7 cell at the density of 25, 50, 100 and 200 ${\mu}g/ml$. 3. CF inhibited significantly increasing the production of Intracellular Ca in LPS-induced RAW 264.7 cell at the density of 25, 50, 100 and 200 ${\mu}g/ml$. 4. CF inhibited significantly the IL-2, IL-10, IL-12p70, TNF-${\alpha}$, GM-CSF, M-CSF, LIF and VEGF of the RAW 264.7 cell induced by LPS at the density of 25, 50, 100 and 200 ${\mu}g/ml$. 5. CF inhibited significantly the IL-4 at the density of 25, 50 ${\mu}g/ml$, the IL-5, IL-15 and MIG at the density of 25, 50 and 200 ${\mu}g/ml$ and IFN-${\gamma}$ at the density of 25, 100 ${\mu}g/ml$ respectively in the RAW 264.7 cell increased by LPS. Conclusions: CF inhibited significantly increasing IL-2, IL-10, IL-12p70, TNF-${\alpha}$, GM-CSF, M-CSF, LIF, VEGF, NO and Ca in LPS-induced RAW 264.7 cell at the density of more than 25 ${\mu}g/ml$ without causing the toxicity.

  • This study aimed at examining the anti-inflammatory effects of Scutellariae Radix & Lonicerae Caulis water extract(SC). RAW 264.7 mouse macrophage cells were treated with $25{\sim}200{\mu}g/m{\ell}$ SC for 24 hours. Cell viability was then measured using MTT assays. The nitric oxide(NO) production and the creation of several cytokines in LPS-stimulated RAW 264.7 cells were investigated. SC inhibited significantly increasing the production of NO in LPS-induced RAW 264.7 cell at the density of 25, 50 and $200{\mu}g/m{\ell}$. SC inhibited significantly the TNF-${\alpha}$ of the RAW 264.7 cell induced by LPS at the density of $50{\mu}g/m{\ell}$. SC inhibited significantly the MIP-$1{\alpha}$ of the RAW 264.7 cell induced by LPS at the density of 25, 50 and $100{\mu}g/m{\ell}$. SC inhibited significantly the MIP-$1{\beta}$, MIP-2 at the density of 50, $100{\mu}g/m{\ell}$ in the RAW 264.7 cell increased by LPS, respectively. SC did not affect the production levels of VEGF in RAW 264.7 cell. As a result, SC significantly inhibited the inductions of MIP-$1{\alpha}$, MIP-$1{\beta}$, MIP-2 and NO in LPS-induced RAW 264.7 cell without causing the toxicity. These results signify that SC has anti-inflammatory effects on controlling the over inflammatory reaction on the RAW 264.7 cell.

Inhibitory effects of YUGHS on Propionibactrium acnes were investigated by using paper disk diffusion method. Results : 1. YUGHS has no cytotoxicity under 50 ${\mu}g/ml$ concentration but over 50 ${\mu}g/ml$ has a little cytotoxicity in Raw 264.7 cell. 2. Concentration of 100 ${\mu}g/ml$ YUGHS inhibited the production of NO in the Raw 264.7 cell stimulated with LPS. 3. All concentrations of YUGHS did not inhibit the production of $TNF-{\alpha}$ in the Raw 264.7 cell stimulated with LPS. 4. All concentrations of YUGHS significantly inhibited the production of $PGE_2$ in the Raw 264.7 cell stimulated with LPS. 5. YUGHS did not inhibit the expression of COX-2 but concentration of 50 ${\mu}g/ml$ YUGHS inhibited iNOS expression in the Raw 264.7 cell stimulated with LPS. 6. YUGHS has the effect of blocking $NF-{\kappa}B$ into nucleus in LPS-induced macrophage Raw 264.7 cell 7. YUGHS did not have the inhibitory effect of Propionibactrium acnes. Conclusions : These results indicate that Yeouigeumhwang-san has anti-inflammatory effets. If further study is performed, the use of Yeouigeumhwang-san will be valuable and benificial in the therapy of acnes.

  • Purpose: This study was performed to evaluate the effect of Clematidis Radix extract(CB) on osteoclast differentiation and gene expression. The osteocastogenesis and gene expression were determined in RANKL-induced RAW 264.7 cell. Methods: RANKL-induced RAW 264.7 cell with Clematidis Radix extract was stained by TRAP which is expressive marker of osteoclast. The gene expression of RANK, $TNF{\alpha}$, IL-6, iNOS and Cathepsin, those are factors related to bone resorption, was estimated by using Reverse Transcription-Polymerase Chain Reaction (RT-PCR). Results: Clematidis Radix extract decreased the number of TRAP-positive multi nuclei cell, and decreased the gene expression of RANK, $TNF{\alpha}$, IL-6, iNOS and Cathepsin K in RANKL-induced RAW 264.7 cell. Conclusion: It is concluded that Clematidis Radix extract might decrease the bone resorption resulted from decrease of osteoclast differentiation and it's related gene expression.
