  • Objectives: Hwangryunhaedok-tang (HRHDT), a prescription composed of four herbs, has been wi dely used in Oriental Medicine for the treatment of cerebral infarction. However, the mechanisms by which the herbal formula affects on the production of pro- and anti-inflammatory cytokines in cerebral infarction patients remain unknown yet. Methods: The levels of pro- and anti-inflammatory cytokines, including tumor necrosis factor (TNF)-a, interleukin (IL)-1b, and IL-6, IL-10, and TGF-${\beta}1$ were determined in peripheral blood mononuclear cells (PBMCs) from cerebral infarction patients under our experimental conditions. Results: The secretory levels of pro- and anti-inflammatory cytokines, including tumor necrosis factor (TNF)-a, interleukin (IL)-1b, and IL-6, and IL-10 were significantly increased in phytohemagglutinin (PHA)-stimulated peripheral blood mononuclear cells (PBMCs) from cerebral infarction patients. However, pretreatment with HRHDT significantly inhibited the secretion of pro- and anti-inflammatory in PBMCs. Also, HRHDT induced a significant increase of transforming growth factor (TGF)-b1 in PBMCs. Conclusions: These data indicate that HRHDT may be beneficial in the suppression of inflammatory processes of cerebral infarct through suppression of TNF-$\alpha$, IL-$1{\beta}$, IL-6, and IL-10 and induction of TGF-${\beta}1$.

  • Pro-inflammatory cytokines, interleukin-$1{\beta}$(IL1B), IL6, and tumor necrosis factor-alpha (TNF), are known to play important roles in regulating the endometrial function in the uterus during the estrous cycle and pregnancy in several species. However, the expression and function of these cytokines and their receptors in the uterine endometrium during the estrous cycle have not been studied in pigs. Thus, this study determined the expression and regulation of IL1B, IL6, TNF and their respective receptors, IL1R1, IL1RAP, IL6R, GP130, TNFRSF1A, and TNFRSF1B during the estrous cycle in pigs. To analyze levels of each gene expression in the uterine endometrium we obtained from endometrial tissues on Days 0, 3, 6, 9, 12, 15, and 18 of the estrous cycle. Real-time RT-PCR analysis showed that levels of IL1B, IL1RAP, IL6R, GP130, TNF, TNFRSF1A, and TNFRSF1B mRNAs were highest on Day 15 or 18 of the estrous cycle, which corresponds to the proestrus period. Levels of IL1R1 were highest on Day 0, while levels of IL6 were biphasic with high levels on Day 6 and Day 15. The abundance of IL1B, IL6, IL6R, and TNF mRNAs was decreased by progesterone, while levels of GP130 were increased by progesterone in endometrial tissue explants. These results showed that expression of pro-inflammatory cytokines and their receptors changed stage-specifically during the estrous cycle and regulated by progesterone in the uterine endometrium in pigs, suggesting that these pro-inflammatory cytokines may be involved in the regulation endometrial function during the estrous cycle in pigs.

  • The anti-inflammatory activity of Eurya emarginata (Thumb) Makino, of which leaves have been traditionally used to treat ulcers or diuretic in Jeju Island, has been investigated in the present study. Through the phytochemical study from the methanol extract of E. emaginiata, eutigosides Band C were isolated as the active components. Sseveral inflammatory markers including TNF-$\alpha$, IL-1$\beta$, IL-6, NO, iNOS, and COX-2 were examined. Eutigosides Band C potentially inhibited production of pro-inflammatory cytokines (IL-6 and TNF-$\alpha$) in a dose-dependent manner. Additionally, the intracellular contents of iNOS protein were markedly decreased after treatment with eutigosides Band C. The inhibition of iNOS activity was correlated with the decrease in nitrite levels. These results suggest that eutigoside Band C from E. emarginata may have anti-inflammatory activity through the inhibition of pro-inflammatory cytokines (TNF-$\alpha$ and IL-6), iNOS and COX-2.

  • This study was carried out to know the immunity responses of Sogyughwalhyel-tanggami(SGHHT) to on Rheumatoid Arthritis in Collagen-induced Arthritis(CIA) Mice. Various experimental were peformed to analyse the immunity effects of SGHHT. The cytotoxicity against mLFCs was not measured. The production of pro-inflammatory cytokines $IL-1{\beta}$, IL-6, $TNF-\alpha$ were reduced in hFLSs. The production of pro-inflammatory cytokines $IFN-\gamma$, IgG3, IgG2b, IgM were reduced. Comparison of the results for this study showed that SGHHT had immunomodulatory effects of suppressing or enhancing. So we expect that SGHHT should be used as a effective drugs for not only rheumatoid arthritis but also another auto-immune disease. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

  • A comprehensive study on the production of inflammatory mediators in the lungs of BALB/c mice following infection with Stenotrophomonas maltophilia was conducted. The levels of pro-inflammatory cytokines, tumor necrosis factor alpha (TNF-${\alpha}$), and interleukin-1${\beta}$ (IL-1${\beta}$) were raised in the lungs of infected mice compared with control. The production of anti-inflammatory cytokine IL-10 was slightly delayed. Its peak level was on the $2^{nd}$ day, whereas the peak of pro-inflammatory cytokines was observed on day 1 after intranasal challenge. This was accompanied by a rise in myeloperoxidase (MPO) and malondialdehyde (MDA) on day 1. The increase in MPO levels matched with histopathological observations, as neutrophils infiltration was detected on the first day. Alveolar macrophages (AMs) obtained from infected animals showed a higher rate of uptake and killing when exposed to bacteria in vitro, compared with similar experiments conducted with AMs from normal mice (control). This suggests that AMs were more efficient in cleaning the bacteria. The nitric oxide (NO) production however started early during infection but reached its maximum on the $3^{rd}$ day. No mortality was observed among the infected animals, and infection was resolved by the $5^{th}$ day post infection. No drastic changes in the lung tissue were observed on histopathological examination.

  • Pro-inflammatory cytokines, such as tumor necrosis factor $(TNF)-{\alpha}$, interleukin-12 (IL-12) and interleukin $(IL-1)-{\beta}$, play a key role in causing inflammatory diseases, which are rheumatoid arthritis, Crohn's disease and sepsis. Accumulating evidences suggest that low level laser irradiation (LLLI) may have an anti-inflammatory action. However, there are few data regarding down regulation of Th1 immune response by using the diod typed laser emitting device for human patients. As a fundamental step in order to address this issue, we investigated immunological impact of the low level laser irradiation (10 mw laser diode with a wavelength of 630 nm) on expression of pro-inflammatory cytokines in murine immunocytes (splenocytes and peritoneal macrophages) in vitro. The LLLI on lipopolysaccharide (LPS 100 ng/ml)-stimulated murine splenocytes and macrophages, clearly down regulated mRNA expression of $TNF-{\alpha}$ and IL-12 in dose-dependent manner. In addition, LLLI significantly inhibits the NO production in the LPS-stimulated murine macrophages. This data suggests that LLLI (wavelength of 630 nm) may exert an anti-inflammatory action via modulation of pro-inflammatory cytokine and NO production pathway.

  • Eurya emarginata (Thunb.) Makino (Theaceae) is distributed in coastal areas of island. The leaves of Eurya are used in the traditional medicine of the coastal areas of jeju island with the aim of diuresis or to treat ulcers. Nevertheless, there are few reports on the biological activity and constituents of E. emarginata. In this study, we investigated the pharmacological activity of the solvent extracts of E. emarginata on the several inflammatory markers (TNF-$\alpha$, IL-1$\beta$, IL-6, NO, iNOS and COX-2). Also we examined the antioxidizing effect of the solvent extracts by determination of DPPH radical-scavenging activity. Among the solvent fractions, EtOAc and BuOH extracts showed potent radical scavenging activity (RC$_{50}$=10.9 and 12.7 respectively). The subtractions of EF 5-4-6-3-2 and BF 1 potentially inhibited the mRNA expression of pro-inflammatory cytokines (IL-1$\beta$, IL-6 and TNF-$\alpha$) at the concentration of 100 $\mu\textrm{g}$/mι. Also the fractions inhibited the mRNA expression of pro-inflammatory cytokines (IL-1$\beta$, IL-6 and TNF-$\alpha$) and protein expression of iNOS and COX-2 at the concentration of 100 $\mu\textrm{g}$/mι. And then, the inhibition of iNOS was correlated with the decrease of nitrite level. These results suggest that E. emarginata may have anti-inflammatory activity through the inhibition of pro-inflammatory cytokines, iNOS and COX-2.2.

  • Background: Mizoribine (MZR) is an imidazole nucleoside isolated from Eupenicillium brefeldianum. MZR is currendy in clinical use for patients who have undergone renal transplantation. Therapeutic efficacy of MZR has also been demonstrated in rheumatoid arthritis and lupus nephritis. MZR has been shown to inhibit the proliferation or lymphocytes by interfering with inosine monophosphate dehydrogenase. Since the exact mechanism by which MZR benefits rheumatoid arthritis (RA) is not clear, we investigated the ability of MZR to direct its immunosuppressive influences on other antigen presenting cells, such as macrophages. Methods: Mouse macrophage RAW264.7 cells were stimulated with lipopolysaccharide in the presence of MZR. To elucidate the mechanism of the therapeutic efficacy in chronic inflammatory diseases, we examined the effects of MZR on the production of pro-inflammatory cytokines, nitric oxide (NO) and prostaglandin $E_2\;(PGE_2)$ in macrophages. Results: MZR dose-dependendy decreased the production of nitric oxide and pro- inflammatory cytokines such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukins $1{\beta}$ (IL-${\beta}$ and IL-6 $PGE_2$. Examination of gene expression levels showed that the anti-inflammatory effect correlated with the down-regulation of inducible nitiric oxide synthase expression, cycloxygenase-2 expression and TNF-${\alpha}$ gene expression. Conclusion: In this work, we resulted whether MZR $(1.25{\sim}10{\mu}g/ml)$ inhibited macrophage activation by inhibiting secretion of pro-inflammatory cytokines, NO and $PGE_2$. These findings provide an explanation for the therapeutic efficacy of MZR in chronic inflammation-associated diseases.

  • The process of spontaneous abortion involves a complex mechanism with various cytokines, growth factors, and hormones during the pregnancy. However, the mechanism underlying spontaneous abortion by pro- and anti-inflammatory cytokines in the serum during the pregnancy is not fully understood. Therefore, the purpose of this study was to examine the relationship between the serum levels of pro- and anti-inflammatory cytokines and spontaneous abortion using the $CBA/j{\times}DBA/2$ mouse model. Serum levels of pro-inflammatory cytokines, such as $IFN-{\gamma}$, $IL-1{\alpha}$ and $TNF-{\alpha}$ were not increased in abortion model mice, but anti-inflammatory cytokines, such as IL-4, IL-13 and IL-1ra were decreased compared to normal pregnant mice. In addition, serum levels of chemokine, such as SDF-1, G-CSF, M-CSF, IL-16, KC and MCP-1 were decreased in abortion model mice compared to normal pregnant mice. However, the expression levels of nesfatin-1/NUCB2 mRNA and protein in the uteri of implantation sites were significantly higher in abortion model mice than normal pregnant mice. These results suggest that uterine nesfatin-1/NUCB2 expression may be down-regulated by inflammatory cytokines and chemokines in the serum of pregnant mice. Moreover, this study suggests the possibility that nesfatin-1/NUCB2 expressed in the implantation sites may be associated with the maintenance of pregnancy.
