  • In this study, the purification of the MeOH extract from the stems and leaves of Pourthiaea villosa var. brunnea using column chromatography furnished a main compound, lyoniside. The structure was elucidated on the basis of $^1H$ and $^{13}C$ NMR spectroscopic data. Quantitative analysis of lyoniside was conducted by HPLC method and the highest content of lyoniside was found in 50% MeOH reflux extraction. To investigate the anti-inflammatory effect of the lyoniside, we measured nitric oxide and pro-inflammatory cytokines such as TNF-${\alpha}$, IL-$1{\beta}$, IL-6 levels in lipopolysaccharide-induced murine macrophage cell line RAW 264.7. As a results, lyoniside decreased the level of nitric oxide and IL-6 in concentration dose dependent manner in RAW 264.7 cells.

  • This study was planned to estimate the activity of bovine circulating blood lymphocytes using phytohemagglutinin-M(PHA) known as T cell mitogen. Bovine circulating blood mononuclear cells(MNCs) was separated, and cultured with or without macrophage($PHA^+/M{\phi}^+$ or $PHA^+/M{\phi}^-$) in conditioned medium which stimulated with various concentration of PHA(0, 5, 10, 15 and $20{\mu}g/ml$ in medium), and then investigated the blastogenic response and rosette formation of lymphocytes. Blastogenic rate(BR) was especially increased in PHA concentration(10 and $15{\mu}g/ml$) of $PHA^+/M{\phi}^+$ group and their BR were $41.5{\pm}6.8%$ and $44.4{\pm}8.9%$, respectively and BR in PHA concentration(15 and $20{\mu}g/ml$) of $PHA^+/M{\phi}^-$ group was $32.8{\pm}6.2%$ and $31.4{\pm}4.6%$, respectively. BR of lymphocytes was more increased in $PHA^+/M{\phi}^+$ than $PHA^+/M{\phi}^-$ group when these cells were stimulated by PHA. Rosette forming rate(RFR) of lymphocytes to SRBC highly increased when SRBC was treated with AET and/or dextran, respectively. On the orther hand, RFR significantly increased more in $PHA^+/M{\phi}^+$ and $PHA^+/M{\phi}^-$ group than in control group, but when compared with two groups, statistical significancy was recognized only in PHA concentration($15{\mu}g/ml$, p<0.026) of $PHA^+/M{\phi}^+$ group.

  • The phagocytic petencies and birefringences of peritoneal mast cells of rats treated with particular dyes (neutral red, toluidine blue, pyronin, methylene blue, alcian blue, trypan blue, carmine, orange G, aniline blue, Janus green B, and India ink) were analyzed by means of phase contrast microscopy and polarizing microscopy. In addition, cytomorphic effects of the dyes on the peritoneal mast cells were also discussed. Phagocytic activities or ingestion of the dye particles were not observed in most cases, except for the India ink group. Hardly a macrophage appeared without some dark particles which were ingested or phagocytosed. Trypan blue and aniline blue produced very weak birefringence in the cytoplasm of mast cells but the rest did not produce even in the acid medium (neutral red and toluidine blue). The short and slender ectoplasmic processes of the mast cells and the leucocytes were also found in certain groups. The cytomorphic effects of the dyes on the mast cell were slight and variable.

  • Objectives : Evodia officinalis DODE (EO), an herbal plant, has been widely used in traditional Korean medicine for the treatment of vascular diseases such as hypertension. The crude extract of EO contains phenolic compounds that are effective in protecting liver microsomes, hepatocytes, and erythrocytes against oxidative damage. But EO has been little found to have an anti-inflammatory activity. We investigated anti-inflammatory activity of EO in RAW 264.7 cells and human umbilical vein endothelial cells (HUVECs). Methods : Cytotoxic activity of EO on RAW 264.7 cells was investigated by using 5-(3-caroboxymeth-oxyphenyl)-2H-tetra-zolium inner salt (MTS) assay. The nitric oxide (NO) production was measured by Griess reagent system. And proinflammatory cytokines were measured by ELISA kit. The levels of intracellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) expression were measured by flow cytometer. Results : EO decreased LPS-induced NO production in RAW 264.7 cells. The inhibitory activity of EO on LPS-induced NO release is probably associated with suppressing TNF-${\alpha}$, IL-6 and MCP-1 formation. These results indicate that EO has potential as an anti-inflammatory agent. Moreover, EO decreased TNF-${\alpha}$-induced IL-8, IL-6 production, and ICAM-1 and VCAM-1 expression in HUVECs. Conclusions : EO inhibits TNF-${\alpha}$-induced inflammation via decreasing cytokines production and adhesion molecules expression. These results indicate that EO has potential as an anti-inflammation and anti-artherosclerosis agent.

  • 1. Objectives Yanggyuksanhwa-tang for Soyangin was applied to investigate the immunological activities on antigen (Ag)-specific or Ag-non-specific immune responses on murine macrophage cell line (RAW 264.7) and ovalbumin/aluminium (OVA/Alum)-immunized mice. 2. Methods This study were carried out in nitric oxide (NO) synthesis on RAW 264.7 cells and cellular proliferation on mouse splenocytes. C57BL/6 mice were immunized intraperitonially with OVA/Alum (100 ${\mu}g$/200 ${\mu}g$) on day 1, 8, and 15. Yanggyuksanhwa-tang was administrated to mice orally for 3 weeks from day 1. On day 22, OVA-, lipopolysaccharide (LPS)-, and concanavalin A (Con A)-stimulated splenocyte proliferation and antibodies (OVA-specific antibodies of the IgG, IgG1, and total IgM classes) in plasma were measured. 3. Results Yanggyuksanhwa-tang significantly enhanced cellular proliferation by LPS and Con A on splenocytes from OVA/Alum-immunized mice (p<.001). Yanggyuksanhwa-tang also significantly enhanced plasma OVA-specific IgG (p<.001), IgG1 (p<.001), and total IgM (p<.01) levels compared with the OVA/Alum group. 4. Conclusions These results suggested that Yanggyuksanhwa-tang for Soyangin could be used as immunopotent.

  • Multinucleated bone resorptive osteoclasts differentiate from bone marrow-derived monocyte/macrophage precursor cells. During osteoclast differentiation, mononuclear pre-osteoclasts change their morphology and biochemical characteristics. In this study, Raman spectroscopy with multivariate techniques such as Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) were used to extract biochemical information related to various cellular events during osteoclastogenesis. This technique allowed for label-free and noninvasive monitoring of differentiating cells, and clearly discriminated four different time points during osteoclast differentiation. The Raman band intensity showed significant time-dependent changes that increased up to day 4. The results of Raman spectroscopy agreed with results from atomic force microscopy (AFM) and tartrate-resistant acid phosphatase (TRAP) staining, a conventional biological assay. Under AFM, normal spindle-like mononuclear pre-osteoclasts became round and smaller at day 2 after treatment with a receptor activator of nuclear $factor-{\kappa}B$ ligand and they formed multinucleated giant cells at day 4. Thus, Raman spectroscopy, in combination with PCA-LDA, may be useful for noninvasive label-free quality assessment of cell status during osteoclast differentiation, enabling more efficient optimization of the bioprocesses.

  • Effects of Citrus sunki peel and its fermented product extracts on physiological and functional activities of cellular systems were investigated. Ethanol extract of Citrus sunki peel showed potent ROS-scavenging activity using 2',7'-Dichlorofluorescin diacetate as a fluorescent ROS probe in HepG2 cells. Fermented product of C. sunki peel extract markedly suppressed nitric oxide production in lipopolysaccharide (LPS)-activated RAW264.7 murine macrophage cells. Treatment with fermented product of C. sunki peel extract decreased intracellular protein levels of inducible nitric oxide synthase and cyclooxygenase II stimulated by LPS. High doses of fermented product lend to apoptotic cell death in CHO-IR cells.

  • Objective: To derive information on the efficacy of Sam-chul-kun-bi-tang (SKT), by evaluating its anti-inflammatory effect. SKT is a widely-used herbal formula in traditional Korean medicine. In man y studies, plant-derived anti-inflammatory efficacies have been investigated for their potential inhibitory effects on lipopolysaccharide (LPS)-stimulated macrophages. This study was performed to examine the anti-inflammatory effects of SKT extract on LPS-stimulated RAW 264.7 cells. Methods: The production of nitric oxide (NO), prostaglandin $(PG)E_2$, tumor necrosis factor (TNF)-$\alpha$ and interleukin (IL)-6 were examined in a macrophage cell line, RAW 264.7 cells, in the presence of SKT. RAW 264.7 cells were incubated with LPS 1 ${\mu}g/mL$ and SKT for 18 hrs. The anti-inflammatory activity of SKT was investigated by carrageenan-induced paw edema in rats. The paw volume was measured at 2 and 4 hrs following carrageenan-induced paw edema in rats. Results: SKT showed inhibitory effect on $PGE_2$, TNF-$\alpha$ and IL-6 in LPS-stimulated RAW 264.7 cells. But SKT was not inhibitory effect on NO by LPS-stimulated RAW 264.7 cells. Administration of SKT (1 g/kg) also showed a reduction in carrageenan-induced paw edema on rats. Conclusion: These results suggest that SKT has anti-inflammatory activities in both in vitro and in vivo models.

  • Poncirus Fructus (PF) is obtained by drying the trifoliate orange fruit belonging to the Rutaceae family. In our country of medicine, PF has been used as a treatment of indigestion, allergy and inflammation. But Mechanism and medical data for PF is insignificant. Recently, the effect of the study PF of biological activity was reported, such as anti- thrombosis, anti-bacteria, anti-virus, anti- allergic. We investigated that the effect of PF on anti-inflammatory in murine macrophage-like cell line Raw264.7 cells. Our results show that the expression level of Nitric Oxide (NO) and Matrix-metallopeptidase-9 (MMP-9) significantly decreased. Moreover, to determine the expression level of pro-inflammatory cytokines such as Tumor Necrosis Factor ($TNF-{\alpha}$) and Interleukin-6 (IL-6) and the phosphorylation pattern of signaling molecules of mitogen-activated protein kinase (MAPK) family, we performed ELISA and westren blot in Raw264.7 cells. In addition, nuclear factor-kappa B ($NF-{\kappa}B$) pathway was confirmed. PF extract inhibited the production of $TNF-{\alpha}$ and IL-6. The extract suppressed the phosphorylation of ERK1/2, JNK, and p38 MAPK, and the nuclear translocation of $NF-{\kappa}B$ p65 in activated cells. Our results suggest that PF can be used as a potential therapeutic agent or functional food to relieve inflammation.

  • Quantitative sputum cytometry facilitates in assessing the nature of bronchitis associated with exacerbations of chronic obstructive pulmonary disease (COPD). This is not assessed in most clinical trials that evaluate the effectiveness of strategies to prevent or to treat exacerbations. While up to a quarter of exacerbations may be associated with raised eosinophil numbers, the vast majority of exacerbations are associated with neutrophilic bronchitis that may indicate airway infections. While eosinophilia may be a predictor of response to corticosteroids (oral and inhaled), the limited efficacy of anti-interleukin 5 therapies would suggest that eosinophils may not directly contribute to those exacerbations. However, they may contribute to airspace enlargement in patients with COPD through various mechanisms involving the interleukin 13 and matrix metalloprotease pathways. The absence of eosinophils may facilitate in limiting the unnecessary use of corticosteroids. The presence of neutrophiia could prompt an investigation for the specific pathogens in the airway. Additionally, sputum measurements may also provide insight into the mechanisms of susceptibility to airway infections. Iron within sputum macrophages, identified by hemosiderin staining (and by more direct quantification) may impair macrophage functions while the low levels of immunoglobulins in sputum may also contribute to airway infections. The assessment of sputum at the time of exacerbations thus would facilitate in customizing treatment and treat current exacerbations and reduce future risk of exacerbations.
