  • Objective : Recently interest of fermented herb medicine has increased in Oriental medicine. Herb medicine fermented in a proper condition resultingly has better or new virtue by microbe. This study was designed to compare the anti-inflammatory effects of herbal decoction and fermented herbal decoction in Hwangnyeonhaedok-tang (Huanglian fiedu-tang; HHT). Methods : The effects of HHT and FHHT on anti-inflammation were measured by production of NO and pro-inflammatory cytokine productions including TNF-${\alpha}$ and IL-1${\beta}$, IL-6 in LPS induced RAW 264.7 cells. Results : 1. Cell viability in three doses of HHT extract (0.01, 0.05 and 0.10 mg/ml) and two doses of FHHT extract (0.01, 0.05 mg/ml) was more than 70% and 80% each. 2. In RAW 264.7 cells, LPS displayed significant stimulatory effects on the production of NO. However, both HHT, FHHT showed significant inhibitory effects on the production of NO. 3. Pre-treatment by HHT in a various concentrations (0.01, 0.05, 0.10, 0.50mg/ml) reduced the elevated production of TNF-${\alpha}$, IL-1${\beta}$, IL-1${\beta}$ mRNA, IL-6 mRNA. More than 0.05mg/ml concentrations of HHT reduced the production of IL-6. And TNF-${\alpha}$, IL-1${\beta}$ level of mouse serum reduced in a various dose(0.1, 0.5, 1.0g/kg). 4. Pre-treatment by FHHT in a various concentrations (0.01, 0.05, 0.10, 0.50mg/ml) reduced the elevated production of TNF-${\alpha}$. More than 0.05mg/ml concentrations of FHHT reduced the expression of TNF-${\alpha}$ mRNA. 0.1, 0.50mg/ml concentrations of FHHT reduced the production of IL-6. And IL-1${\beta}$ level of mouse serum reduced in a various dose(0.1, 0.5, 1.0g/kg). Conclusions : These results indicated that both HHT and FHHT could have anti-inflammatory capacity by inhibiting the production of NO and cytokines in vitro. But HHT has more strong anti-inflammatory effects than that of FHHT in broad outlines.

  • The inhibitory effect of omega-3 such as linolenic acid (LNA), docosahexaenoic acid (DNA) and eicosapentaenoic acid(EPA) on the growth of normal cell lines and cancer cell lines was evaluated by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyItetrazolium bromide (MTT) and 2,3-bis-2-methoxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-caboxanilide (XTT) methods. LNA was found to decrease the cell viability of human oral epithelioid carcinoma cells (KB) in the MTT assay, whereas EPA appeared to inhibit the cell adhesion activity of human skin melanoma cells (SK-MEL-3) in the XTT assay analysis. DPPH radical scavenging activity was examined on LNA, DHA and EPA at the concentration of 100 ${\mu}M$, where they showed about 53% scavenging activity. These results suggest that omega-3 unsaturated fatty acid has a potential anticancer activity.

  • Dexmedetomidine is a sedative and analgesic agent that exerts its effects by selectively agonizing ${\alpha}2$ adrenoceptor. Histamine is a pathophysiological amine that activates G protein-coupled receptors, to induce $Ca^{2+}$ release and subsequent mediate or progress inflammation. Dexmedetomidine has been reported to exert inhibitory effect on inflammation both in vitro and in vivo studies. However, it is unclear that dexmedetomidine modulates histamine-induced signaling and pro-inflammatory cytokine expression. This study was carried out to assess how dexmedetomidine modulates histamine-induced $Ca^{2+}$ signaling and regulates the expression of pro-inflammatory cytokine genes encoding interleukin (IL)-6 and -8. To elucidate the regulatory role of dexmedetomidine on histamine signaling, HeLa cells and human salivary gland cells which are endogenously expressed histamine 1 receptor were used. Dexmedetomidine itself did not trigger $Ca^{2+}$ peak or increase in the presence or absence of external $Ca^{2+}$. When cells were stimulated with histamine after pretreatment with various concentrations of dexmedetomidine, we observed inhibited histamine-induced $[Ca^{2+}]_i$ signal in both cell types. Histamine stimulated IL-6 mRNA expression not IL-8 mRNA within 2 hrs, however this effect was attenuated by dexmedetomidine. Collectively, these findings suggest that dexmedetomidine modulates histamine-induced $Ca^{2+}$ signaling and IL-6 expression and will be useful for understanding the antagonistic properties of dexmedetomidine on histamine-induced signaling beyond its sedative effect.

  • The objective of present study is to evaluate concentration-dependent in vitro anti-osteoarthritic (OA) effects of synergic mixed formula consisted of dried pomegranate juice concentrate powder, Eucommiae Cortex aqueous extract and Achyranthis Radix aqueous extract 5:4:1 (g/g) mixture on the primary cultured rat articular chondrocytes. First, any cytotoxic effect of mixture was observed using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium Bromide) assay. Next, cyto-protective effect of test substances was evaluated by using the recombinant human interleukin $(rhIL)-1{\alpha}$ induced chondrocytes. In addition, anti-inflammatory effects were also observed on the lipopolysaccaride (LPS) treated chondrocytes through prostaglandin $E_2(PGE_2)$ productions and 5-lipoxygenase (LPO) activities, and inhibitory effects on matrix metalloproteinase (MMP)-2 and MMP-9 activities were observed on $rhIL-1{\alpha}$ treated chondrocytes with their extracellular matrix (ECM) related mRNA expressions. No obvious cytotoxic effects of mixture were demonstrated. Inflammatory damages of chondrocytes and related ECM degradations induced by treatment of LPS or $rhIL-1{\alpha}$ were significantly and concentration-dependently inhibited by pretreatment of mixture from a concentration level of 0.001 mg/ml to 1 mg/ml. In addition, mixture showed $IC_{50}$ for $rhIL-1{\alpha}-induced$ MMP-2 and MMP-9 activities as 44.01 and $162.47{\mu}g/ml$, and also showed $EC_{50}$ for $rhIL-1{\alpha}-induced$ inhibition of collagen type II, SOX9 and aggrecan mRNA expression as 8.61, 10.79 and $4.47{\mu}g/ml$, respectively. It is observed that mixture showed concentration-dependent anti-inflammatory and cytoprotective ECM preserved effects on the primary cultured rat articular chondrocytes without cytotoxicity.

  • The objective of this study was to investigate the inhibitory effect of taurine and alendronate on the osteoclast differentiation. Osteoblasts and bone marrow cells from 1-2 day old mouse were co-cultured in 10% fetal bovine serum - minimal essential media (FBS-MEM). Osteoclast differentiation was induced by adding the sonicated extracts of Porphyromonas gingivalis (P.gingivalis). Osteoclasts were identified using tartrate resistant acid phosphotase staining (TRAP). Alendronate of 10$^{-7}$, 10$^{-6}$, 10$^{-5}$M and taurine of 500, 1000, 1500$\mu\textrm{g}$/ml were added respectively. The cytotoxic effects of alendronate and taurine were examined using MTT(3-(4,5-dimethylthiazol -2-yl-2,5-diphenyltetrazo- lium bromide) method. After culturing with the sonicated extracts of P.gingivalis, the amounts of IL-6 in the culture supernatant were measured and compared using the ELISA method. The results were as follows : 1. Osteoclasts were differentiated at the concentration of 0.01~0.1$\mu\textrm{g}$/ml sonicated extracts of P.gingivalis. (P<0.05). 2. Alendronate inhibited osteoclasts differentiation at the concentration of 10$^{-5}$ M when the concentration of sonicated extracts of P.gingivalis was 0.01$\mu\textrm{g}$/ml. 3. Taurine inhibited osteoclasts differentiation at the concentration of 1500$\mu\textrm{g}$/ml when the concentration of sonicated extracts of P.gingivalis 0.01$\mu\textrm{g}$/ml. 4. In cytotoxic test (MTT test), no cytotoxic effect was evident in all concentrations of alendronate and taurine. 5. Taurine (10$^{-5}$M) and alendronate(1500$\mu\textrm{g}$/ml) did not change the amounts of IL-6 induced by sonicated extracts of P.gingivalis significantly.

  • Objectives : To clarify the possible effect of Lycium chinese Mill (LC)., Morus alba L (MA)., and Lycium chinese Mill. +Morus alba L. (LC+MA), we have examined their influence on the development of pulmonary eosinophilic inflammation in the asthmatic murine model. Methods : Female Balb/c mice (5weeks) were immunized on two different days (21 days and 7 days before inhalational exposure) by intraperitonial injections of 0.2ml alum-precipitated Ag containing $100{\mu}g$ of OVA bound to 4 mg of aluminum hydroxide in PBS. Seven days after the second sensitization, mice were exposed to aerosolized ovalbumin for 30 minutes/day on 3 days/week for 8 weeks (at a flow rate of 250 L/min, 2.5% ovalbumin in normal saline) and, LC, MA, and LC+MA (500 mg/kg) were orally administered 3 times per a week for 8 weeks. Results : The suppressive effect of LC, MA, and LC+MA were demonstrated by the accumulation of eosinophills into airways, with the reduction of eosinophil, total lung leukocytes numbers. These were correlated with the marked reduction of IL-5, IL-13 and IL-4 levels in the BALF and serum. OVA-specific IgE levels were also decreased in serum and BAL from these mice. LC, MA, and LC+MA decreased eosinophil CCR3 expression and CD11b expression in lung cells. Conclusions : These results indicate that LC, MA, and LC+MA have high inhibitory effects on airway inflammation and hyper-responsiveness in the asthmatic murine model. The suppression of IL-5, IgE, eosinophil CCR3 expression and CD11b expression, and the increase of IFN-${\gamma}$ production in BALF seem to contribute to this effect. Hence, the results indicated that LC, MA, and LC+MA could act as a immuno-modulator which possesses anti-inflammatory and anti-asthmatic property by modulating the imbalance between Th1 and Th2 cytokines.

  • Objectives : The aims of this study were to investigate the cytoprotective, antioxidative and inflammation genes inhibitory effects of Patriniae Radix on the mouse LLC-$PK_1$ cells (renal epithelial cells). Methods : The cytoprotective effect of Patriniae Radix was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The antioxidative effect was measured in terms of generation amount of superoxide anion radical (${\cdot}{O_2}^-$) by 2',7'-dichlorodihydrofluorescein diacetate (DCFDA), nitric oxide (NO) by 4,5-diaminofluorescein (DAF-2), peroxynitrite ($ONOO^-$) by dihyldrorhodamine 123 (DHR 123) and prostaglandin $E_2$ ($PGE_2$) by $PGE_2$ immunoassay on $H_2O_2$-treated LLC-$PK_1$ cells. For measuring of inflammation genes inhibitory effects, western blot was performed to detect IKK-$\alpha$, phospho-$I{\kappa}B-\alpha$, NF-${\kappa}B$ (p50, p65), COX-2, iNOS, IL-$1{\beta}$ and VCAM-1 protein level in cytosol fractions from LLC-$PK_1$ cells. Results : Patriniae Radix extract reduced the $H_2O_2$-induced cell death and inhibited the amount of $H_2O_2$-induced ${\cdot}{O_2}^-$, NO, $ONOO^-$, $PGE_2$ generation dose-dependently on the mouse LLC-$PK_1$ cells in vitro. Also Patriniae Radix extract inhibited the expression of IKK-$\alpha$, phospho-$I{\kappa}B-\alpha$, COX-2, iNOS, IL-$1\beta$ and VCAM-1 genes dose-dependently by means of decreasing activation of NF-${\kappa}B$. Conclusions : According to above results, it was identified that Patriniae Radix had the cytoprotective, antioxidative and inflammation genes inhibitory effects. So it was suggested that Patriniae Radix would be effective to the treatment for the inflammatory process and inflammation-related diseases.

  • BACKGROUND/OBJECTIVES: Schisandrae Fructus, the fruit of Schisandra chinensis Baill., has traditionally been used as a medicinal herb for the treatment of various diseases, and has proven its various pharmacological effects, including anti-inflammatory and antioxidant activities. In this study, we investigated the inhibitory effect of Schisandrae Fructus ethanol extract (SF) on inflammatory and oxidative stress in particulate matter 2.5 (PM2.5)-treated RAW 264.7 macrophages. MATERIALS/METHODS: To investigate the anti-inflammatory and antioxidant effects of SF in PM2.5-stimulated RAW 264.7 cells, the levels of pro-inflammatory mediator such as nitric oxide (NO) and prostaglandin E2 (PGE2), cytokines including interleukin (IL)-6 and IL-1β, and reactive oxygen species (ROS) were measured. To elucidate the mechanism underlying the effect of SF, the expression of genes involved in the generation of inflammatory factors was also investigated. We further evaluated the anti-inflammatory and antioxidant efficacy of SF against PM2.5 in the zebrafish model. RESULTS: The results indicated that SF treatment significantly inhibited the PM2.5-induced release of NO and PGE2, which was associated with decreased inducible NO synthase and cyclooxygenase-2 expression. SF also attenuated the PM2.5-induced expression of IL-6 and IL-1β, reducing their extracellular secretion. Moreover, SF suppressed the PM2.5-mediated translocation of nuclear factor-kappa B (NF-κB) from the cytosol into nuclei and the degradation of inhibitor IκB-α, indicating that SF exhibited anti-inflammatory effects by inhibiting the NF-κB signaling pathway. In addition, SF abolished PM2.5-induced generation of ROS, similar to the pretreatment of a ROS scavenger, but not by an inhibitor of NF-κB activity. Furthermore, SF showed strong protective effects against NO and ROS production in PM2.5-treated zebrafish larvae. CONCLUSIONS: Our findings suggest that SF exerts anti-inflammatory and antioxidant effects against PM2.5 through ROS-dependent down-regulating the NF-κB signaling pathway, and that SF can be a potential functional substance to prevent PM2.5-mediated inflammatory and oxidative damage.
