  • Background: The purpose of this study was to investigate the anti-inflammatory response of lipopolysaccharide (LPS) activated macrophages (RAW 264.7 murine cell line) to JCE003 which is an extract including Eucommia ulmoides, Juglans regia, Eleutherococcus senticosus, and Zingiber officinale. Methods: An MTT [3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide] assay was performed to analyze the survival rate of RAW 264.7 cells. The production of nitric oxide and pro-inflammatory cytokines (IFN-${\gamma}$, TNF-${\alpha}$, IL-$1{\beta}$, IL-6) in LPS-induced RAW 264.7 cells was measured by enzyme-linked immunosorbent assay. mRNA expression levels of pro-inflammatory cytokines (IFN-${\gamma}$, TNF-${\alpha}$, IL-$1{\beta}$, and IL-6) were analyzed by quantitative polymerase chain reaction analysis. Results: Exposure of LPS-activated RAW 264.7 cells to JCE003 was not cytotoxic up to $400{\mu}g/mL$, but cell survival was statistically significantly decreased at $800{\mu}g/mL$ (p < 0.001). Nitric oxide production was not markedly lowered in LPS-activated RAW 264.7 cells by exposure to JCE003 (10, 50, 100, 200, 400, $800{\mu}l/mL$) compared with the Control group. In addition, JCE003 reduced the production of TNF-${\alpha}$ in LPS-induced RAW 264.7 cells at $400{\mu}g/mL$ (p < 0.05), but IFN-${\gamma}$ and TNF-${\alpha}$ mRNA expression in LPS-induced RAW 264.7 cells was decreased at 100, 200, and $400{\mu}g/mL$ JCE003 (p < 0.01). Conclusion: These results suggest that JCE003 inhibited the expression and production of pro-inflammatory cytokines in LPS-activated RAW 264.7 cells. The findings of this study provide basic data for the development of new Korean medicine anti-inflammatory drugs.

  • Cirsium japonicum var. ussuriense is known to have a variety of biological activities, including anti-inflammatory, analgesic activity and antipyretic activity. In this study we investigated the role of polyacetylene compound, 1-Heptadecene-11, 13-diyne-8, 9, 10-triol (PA) from the root of Cirsium japonicum var. ussuriense as an immune-modulator. PA was evaluated as inhibitors of some macrophage functions involved in the inflammatory process. We tested the effect of PA on the production of pro-inflammatory cytokines, interleukin-1beta (IL-$1{\beta}$) and tumor necrosis factor-alpha (TNF-$\alpha$), and nitric oxide (NO) in murine macrophage cell line, RAW264.7. There was no effect on cytokine production of macrophages by PA itself. However, PA inhibited lipopolysaccharide (LPS)-induced IL-$1{\beta}$ and TNF-$\alpha$ production by macrophages at a dose dependent manner. PA also suppressed the NO production of macrophages by LPS. LPS-induced NF-${\kappa}B$ activity was decreased by treatment of PA. Therefore, these results suggest that PA has anti-inflammatory effect by inhibiting the NF-${\kappa}B$ activation.

  • Background and Objective : Chungsangboha-tang (CSBHT) has analgesic, sedative, anti-convulsive and anti-histamine effects, so it alleviates the symptoms of asthma. For the comparison of anti-inflammatory effect(s) on CSBHT, PD098059 was used as a negative control. Materials and Methods : This study emphasized THP-1 cells, which had been well characterized as a human monocytic leukemic cell line. The cells resemble monocytes with respect to several criteria and can be differentiated into macrophage-like cells by treatment with PMA. By using the MTS assay, it was possible to prove the safety of CSBHT. Results : Results shows that the CSBHT did not affected cell survival within $10^{1}$ ng/ml to $10^{5}$ ng/ml. Especially, $10^{5}$ ng/ml CSBHT treated cells show 70% deduction of $TNF-{\alpha}$ gene expression against that of LPS treated group. Furthermore, $IL-1{\beta}$, IL-6, IL-8, IL-10 and $TNF-{\alpha}$ levels are down-regulated when treated with CSBHT with concentrations up to 100 ug/ml on monocyte-derived macrophages. Interestingly, CSBHT-treated samples showed that overall transcriptional activities were down-regulated to 20% of that of PD098059 ($TNF-{\alpha}$ inhibitor). At protein level, the expression of $TNF-{\alpha}$ showed similar results as that of transcriptional activity. Results show that the protein level decreased more in the CSBHT-treated group (487 ${\pm}$ 87 pg/ml) than in the LPS-treated group (703 ${\pm}$ 103 pg/ml). In addition, the protein level of IL-8 in the CSBHT treated-group (9.84 ${\pm}$ 3.28 ng/ml) decreased similar as the expression of the control and PD098059-treated groups. Conclusion : CSBHT affects immune response, especially allergic responses and suppression of inflammatory reaction. The results provide us an alternative way to care for clinical inflammatory diseases, not only asthma but also the other possible general inflammatory and allergic diseases.

  • Cytokines play a central role in the mucosal immune response and are involved in regulation of nutrient absorption, metabolism and animal growth. This study investigated the effect of diet manipulation with specialized protein or peptide sources on expression of cytokine (IL-1, IL-6, IL-10, and TNF-${\alpha}$) mRNA abundance in different intestinal regions and at different ages post-weaning in piglets. A total of 48 (17 days of age, $6.16{\pm}0.34kg\;BW$) weanling pigs were fed either a corn-soy/whey protein basal diet, the basal diet supplemented with spray-dried plasma protein (SDPP), or the basal diet supplemented with $Peptiva^{(R)}$, a hydrolyzed marine plant protein. A fourth treatment group was fed the SDPP diet, but the feed intake level was limited (SDPP-LF). Pigs were killed at 3 and 10 d, and intestinal cytokine mRNA was measured by real-time PCR using the relative quantification method. The SDPP-LF group exhibited an increased TNF-${\alpha}$ mRNA abundance compared with the ad libitum SDPP group (p<0.05). The TNF-${\alpha}$ and IL-10 mRNA abundance increased from the proximal to distal part of the intestine, and the mRNA abundance was greater (p<0.01) in the distal intestine as compared with the proximal and middle intestine. The cytokines IL-1-${\beta}$, IL-10 and TNF-${\alpha}$ mRNA abundance also increased from d3 to d10 postweaning (p<0.01). In summary, restricted feeding increased the TNF-${\alpha}$ mRNA abundance in the small intestine, however neither SDPP nor peptide supplementation affected cytokine mRNA expression. Abundance of mRNA for most cytokines examined in this study increased with age post-weaning, suggesting that during 10 d after weaning the mucosal immune system is still under development.

  • In the present study, we exarnined anti-allergic effect of SGBHB in cultured B cells. B cells were prepared from isolated murine splenocytes and activated by co-treatment of anti-CD40 monoclonal antibody and recombinant IL-4 allergens. Anti-allergic effects of SGBHB in activated B cells were determined by measuring B cell surface activated molecules (CD23+ and CD11a+), and expression levels of IL-$1{\beta}$, IL-6, IL-10, TNF-$\alpha$, IgE, and HRF. The major findings are summarized as follows. 1. SGBHB treatment did not produce significant cytotoxic effects on mouse lung fibroblast cells. 2. SGBHB produced significant inhibitory effect on the expression of B cell surface activated molecules (CD23+ and CD11a) in activated B cells. 3. SGBHB treatment significantly inhibited expression levels of IL-$1{\beta}$, IL-6, and TNF-$\alpha$ mRNAs in activated B cells.IL-6 protein levels were significantly decreased by $100{\mu}g/m{\ell}$ of SGBHB treatrrient, and TNF-$\alpha$ protein levels were decreased compared to the control group, but statistically insignificant. 4. SGBHB treatment significantly increased IL-10 at both mRNA and protein levels in activated B cells. 5. SGBHB treatment significantly inhibited levels of IgE production. Thus, the present data suggest that SGBHB has an anti-allergic effect on activated B cells by controlling irnmune responses, and further implicates the possibility on clinical application as a therapeutic agent.

  • FasL, perforin, $TNF{\alpha}$, IL-1 and NO have been considered as effector molecule(s) leading to ${\beta}$-cell death in autoimmune diabetes. However, the real culprit(s) of ${\beta}$-cell destruction have long been elusive despite intense investigation. Previously we have suggested $IFN{\gamma}/TNF{\alpha}$ synergism as the final effector molecules in autoimmune diabetes of NOD mice. A combination of $IFN{\gamma}$ and $TNF{\alpha}$ but neither cytokine alone, induced classical caspase-dependent apoptosis in murine insulinoma and pancreatic islet cells. $IFN{\gamma}$ treatment conferred susceptibility to $TNF{\alpha}$-induced apoptosis on otherwise resistant murine insulinoma cells by STAT1 activation followed by IRF-1 induction. Here we report that $IFN{\gamma}/TNF{\alpha}$ synergism induces apoptosis of human pancreatic islet cells. We also observed STAT1 activation followed by IRF-1 induction by $IFN{\gamma}$ treatment in human islet cells. Taken together, we suggest that $IFN{\gamma}/TNF{\alpha}$ synergism could be involved in human islet cell death in type 1 diabetes, similar to murine type 1 diabetes.

  • The aim of this study was to evaluate the in vitro anti-inflammatory and utero-relaxant effect of ${\alpha}$-bisabolol on the pregnant human myometrium. Samples from the pregnant human myometrium were used in functional tests to evaluate the inhibitory effect of ${\alpha}$-bisabolol (560, 860, 1,200 and $1,860{\mu}M$) on spontaneous myometrial contractions. The intracellular cyclic adenosine monophosphate (cAMP) levels generated in response to ${\alpha}$-bisabolol in human myometrial homogenates were measured by ELISA. The anti-inflammatory effect of ${\alpha}$-bisabolol was determined through the measurement of two pro-inflammatory cytokines, tumor necrosis factor-${\alpha}$ ($TNF{\alpha}$) and interleukin $(IL)-1{\beta}$, and the anti-inflammatory cytokine IL-10, in pregnant human myometrial explants stimulated with lipopolysaccharide (LPS). Forskolin was used as a positive control to evaluate the cAMP and cytokine levels. ${\alpha}$-Bisabolol was found to induce a significant inhibition of spontaneous myometrial contractions at the highest concentration level (p<0.05). ${\alpha}$-Bisabolol caused a concentration-dependent decrease in myometrial cAMP levels (p<0.05) and a concentration-dependent decrease in LPS-induced $TNF{\alpha}$ and $IL-1{\beta}$ production, while IL-10 production did not increase significantly (p>0.05). The anti-inflammatory and utero-relaxant effects induced by ${\alpha}$-bisabolol were not associated with an increase in cAMP levels in pregnant human myometrial samples. These properties place ${\alpha}$-bisabolol as a potentially safe and effective adjuvant agent in cases of preterm birth, an area of pharmacological treatment that requires urgent improvement.
