Jakyaktang(芍藥湯; JYT) exhibits potent anti-inflammatory activity in widely intestinal disease, but its mechanism was undisclosed. To elucidate the molecular mechanisms of JYT on pharmacological and biochemical actions in inflammation, we examined the effect of JYT on pro-inflammatory mediators in phorbol 12-myristate 13-acetate (PMA) plus A23187-induced mast cell and lipopolysaccharide (LPS)-stimulated macrophages. The investigation focused on whether JYT inhibited pro-inflammatory cytokines such as interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in PMA plus A23187- induced HMC-1 cells and inflammatory madiators such as nitric oxide (NO), TNF-${\alpha}$, IL-6, iNOS, COX-2 in LPS-stimulated RAW 264.7 cells. We found that JYT inhibited LPS-induced NO, TNF-${\alpha}$ and IL-6 productions as well as the expressions of iNOS and COX-2. These results suggest that JYT has inhibitory effects on mast cell-mediated and macropage-mediated inflammation.
BACKGROUND/OBJECTIVES: Although the antioxidative effects of lycopene are generally known, the molecular mechanisms underlying the anti-inflammatory properties of lycopene are not fully elucidated. This study aimed to examine the role and mechanism of lycopene as an inhibitor of inflammation. METHODS/MATERIALS: Lipopolysaccharide (LPS)-stimulated SW 480 human colorectal cancer cells were treated with 0, 10, 20, and $30{\mu}M$ lycopene. The MTT assay was performed to determine the effects of lycopene on cell proliferation. Western blotting was performed to observe the expression of inflammation-related proteins, including nuclear factor-kappa B ($NF-{\kappa}B$), inhibitor kappa B ($I{\kappa}B$), mitogen-activated protein kinase (MAPK), extracellular signal-related kinase (ERK), c-jun NH2-terminal kinase (JNK), and p38 (p38 MAP kinase). Real-time polymerase chain reaction was performed to investigate the mRNA expression of tumor necrosis factor ${\alpha}$ ($TNF-{\alpha}$), interleukin-1 beta ($IL-1{\beta}$), interleukin-6 (IL-6), inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2). Concentrations of nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) were determined via enzyme-linked immunosorbent assays. RESULTS: In cells treated with lycopene and LPS, the mRNA expression of $TNF-{\alpha}$, $IL-1{\beta}$, IL-6, iNOS, and COX-2 were decreased significantly in a dose-dependent manner (P < 0.05). The concentrations of $PGE_2$ and NO decreased according to the lycopene concentration (P < 0.05). The protein expressions of $NF-{\kappa}B$ and JNK were decreased significantly according to lycopene concertation (P < 0.05). CONCLUSIONS: Lycopene restrains $NF-{\kappa}B$ and JNK activation, which causes inflammation, and suppresses the expression of $TNF-{\alpha}$, $IL-1{\beta}$, IL-6, COX-2, and iNOS in SW480 human colorectal cancer cells.
1. Objectives The roots of Sophora flavescens Aiton (SFA) are widely used as a herbal remedy for allergic inflammation. In this study, we invested the effect of SFA on passive cutaneous anaphylaxis reaction and histamin releas and we demonstrated that SFA suppressed the production of pro-inflammatory cytokines, such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin- 6 (IL-6), and interleukin -8 (IL-8), through inhibition of the $NF{\kappa}B$, JNK and p38 pathway in the human mast cell line, HMC-1. 2. Methods To accomplish this, we invested passive cutaneous anaphylaxis reaction and histamin release at an animal experiment. In addition, we investigated the effect of SFA on the production of inflammation-related cytokines in HMC-1 cells that were co-treated with PMA and A23187, which can induce production of pro-inflammatory cytokines. 3. Results and Conclusions SFA induced passive cutaneous anaphylaxis reaction and histamin releas and supressed the expression of TNF-${\alpha}$, IL-6, and IL-8. In addition, the protein levels of TNF-${\alpha}$ were also decreased by SFA treatment. Furthermore, SFA inhibited the nuclear translocation of nuclear factor $NF{\kappa}B$ through inhibition of the phosphorylation and degradation of $I{\kappa}B-{\alpha}$, which is an inhibitor of $NF{\kappa}B$. Moreover, SFA also inhibited induction of MAPKs (JNK, p38) and $NF{\kappa}B$ promoter-mediated luciferase activity. Taken together, these results suggest that SFA could be used as a treatment for mast cell-derived allergic inflammatory diseases.
Objectives : Allium hookeri is a well-known traditional herbal remedy and its root used for treatment of inflammation and tumor. However, the mechanism of anti-inflammatory effect of Allium hookeri is still unknown. This study aims to examine the mechanism of anti-inflammatory effect of Allium hookeri on mouse macrophage cell line, RAW 264.7 cells. Methods : Anti-oxidant effect of water extract of Allium hookeri (WEAH) was measured by 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assay. 3- (4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay was performed to determine the effect of WEAH on cell viability in RAW 264.7 cells. In addition, anti-inflammatory effect of WEAH was investigated in RAW 264.7 cells. Inflammation of RAW 264.7 cells induced by lipopolysarccharide (LPS) treatment and expression levels of inflammatory cytokine interleukin 1 β (IL-1β) and interleukin 6 (IL-6) gene were analyzed using quantitative reverse transcription PCR (qRT-PCR) analysis. Furthermore, the phosphorylation of inhibitor of nuclear factor kappa B (IκBα) after LPS treatment with WEAH-treated RAW 264.7 cells was confirmed by immunoblot analysis. Results : WEAH showed a strong anti-oxidant effect and no cytotoxicity to RAW 264.7 cells up to 2 mg/㎖ concentration. The LPS-induced mRNA expression levels of IL-1β and IL-6 were decreased by WEAH treatment. Furthermore, the LPS-induced phosphorylation of IκBα is attenuated by WEAH treatment. Conclusions : Through experimental demonstration of anti-oxidant and anti-inflammatory effects of WEAH, we suggest that Allium hookeri is a valuable material for prevention and treatment of various inflammatory diseases.

Objective: To identify differences in the expression of the genes for peroxisome proliferator-activated receptor $(PPAR)-{\gamma}$, cyclooxygenase (COX)-2, and the proinflammatory cytokines interleukin (IL)-6 and tumor necrosis factor $(TNF)-{\alpha}$ in granulosa cells (GCs) from polycystic ovary syndrome (PCOS) patients and controls undergoing controlled ovarian stimulation. Methods: Nine patients with PCOS and six controls were enrolled in this study. On the day of oocyte retrieval, GCs were collected from pooled follicular fluid. Total mRNA was extracted from GCs. Reverse transcription was performed and gene expression levels were quantified by realtime quantitative polymerase chain reaction. Results: There were no significant differences in age, body mass index, and total gonadotropin dose, except for the ratio of luteinizing hormone to follicle-stimulating hormone between the PCOS and control groups. $PPAR-{\gamma}$ and COX-2 mRNA was significantly downregulated in the GCs of PCOS women compared with controls (p= 0.034 and p= 0.018, respectively), but the expression of IL-6 and $TNF-{\alpha}$ mRNA did not show significant differences. No significant correlation was detected between the expression of these mRNA sequences and clinical characteristics, including the number of retrieved oocytes, oocyte maturity, cleavage, or the good embryo rate. Positive correlations were found among the $PPAR-{\gamma}$, COX-2, IL-6, and $TNF-{\alpha}$ mRNA levels. Conclusion: Our data may provide novel clues regarding ovarian GC dysfunction in PCOS, and indirectly provide evidence that the effect of $PPAR-{\gamma}$ agonists in PCOS might result from alterations in the ovarian follicular environment. Further studies with a larger sample size are required to confirm these proposals.
Objectives: This study was designed to examine immuno-modulatory effects of Evodia Rutaecarpine by activating innate immune system and inhibiting inflammation. Methods: First, Cell cytotoxicity was examined with 4T1 breast carcinoma and TG-induced macrophage. To investigate activating innate immune system of Evodiamine Rutacarpine Extract (ERE) on macrophage, we tested tumor necrosis factor-alpha (TNF-α), interleukin-12 (IL-12), and interleukin-6 (IL-6). In addition, TNF-α and nitric oxide (NO) induced by lipopolysaccharide (LPS) were measured after treating with ERE to observe innate immune modulating effect of ERE on RAW 264.7 cell. Also, mitogen-activated protein kinase (MAPK) and nuclear factor κB (NF-κB) were examined by western blot analysis. Results: In cytotoxicity analysis, ERE significantly affected tumor cell growth above specific concentration. Also, ERE significantly affected macrophage growth above specific concetration. As compared with the control group, the production of TNF-α, IL-12 and IL-6 were increased in TG-induced macrophage. As compared with the control group, TNF-α and IL-6 were significantly up-regulated in RAW 264.7 cell. The expression of TNF-α and NO induced by LPS after treating ERE was significantly decreased compared with control group. In addition, We observed ERE inhibited the phosphorylation levels of p-extracellular signal-regulated kinase (p-ERK), p-Jun N-terminal kinase (p-JNK), and p-p38 in western blotting by treating ERE on RAW 264.7 cell. Conclusions: ERE seems to have considerable impact on the anti-cancer effect by activation of innate immune system and inflammation control.
Background: The washing of packed red blood cells could remove pro-inflammatory mediators, cell debris, and micro-particles contained in packed red blood cells, and the preci-rculation-ultrafiltration (recirculation and ultrafiltration of circuit itself before cardiopulmonary bypass) could attenuate the initial inflammatory reaction and remove the initial proinflam-matory mediators. This study was performed to evaluate whether the washing of packed red blood cells and precirculation-ultrafiltration can reduce the production of cytokines that have an important role in myocardial reperfusion injury. This study investigated the effects of washing the packed red blood cells and precirculation-ultrafiltration on the production of cytokines during and after cardiopulmonary bypass and open heart surgery. Material and Method: Forty eight infants with VSD undergoing open heart surgery under cardiopulmonary bypass were randomized into control group (group C, n=12), washing group (group W, n= 12), precirculation-ultrafiltration group (group F, n: 12), and combined group(washing and precirculation-ultrafiltration, group WF, n=12). Blood samples were obtained before, during, and after the bypass to assess plasma level of tumor necrosis factor-$\alpha$(TNF-$\alpha$), interleukin-6(IL-6), and interleukin-8 (IL-8). Results: Expressions of TNF-$\alpha$ were significantly reduced in combined group (group WF) compared with group C, group W, and group F (p<0.05). Expression of IL-6 were significantly reduced in group W, group F, and group WF compared with group C (p<0.05), but similar among group W, group F, and group WF (p=0.053). Expression of IL-8 were reduced in group W and group WF compared with group C (p<0.05), but similar among group W, group F, and group WF (p=0.067). Conclusion: In conclusion, the washing of packed red blood cells and precirculation-ultrafiltration blunted the increase of TNF-$\alpha$ , IL-6, and IL-8 during and after open heart surgery with cardiopulmonary bypass. However, the clinical benefits of these treatments remains unproven.
We investigated the effect of black soybean and doenjang with black soybean on production of cytokines including interleukin-2 (IL-2), interleukin-6 (IL-6) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) compared with yellow soybean and doenjang with yellow soybean. We also determined inhibitory effect of two types of soybeans and doenjang on tumor metastasis produced by colon 26-M3.1 carcinoma cells. The cytokine productions of mouse splenocytes increased by the exposure of lipopolysaccharide (LPS, 1 ${\mu}g$/ml) compared to without treatment of LPS. The LPS-induced IL-2 production was highest in the black soybean methanol extract, while the methanol extract from black soybean doenjang fermented for 2 mo showed the higher levels of IL-2 without LPS (p<0.05). In case of LPS-induced IL-6 production, the methanol extracts from control, yellow soybean, black soybean doenjang fermented for 2 and 7 mo showed higher levels of IL-6 compared to those of black soybean, and yellow soybean doenjang fermented for 2 mo (p<0.05). The methanol extract of black soybean doenjang fermented for 2 mo showed significantly higher levels of TNF-${\alpha}$ in both with and without LPS (p<0.05). In experiment of tumor metastasis, the treatment (1 mg/mouse) of methanol extract from black soybean doenjang fermented for 7 mo inhibited tumor metastasis by 50% and had the highest inhibitory effect among other samples (p<0.05). From these results, doenjang manufactured with black soybean modulated the production of cytokine and showed anticancer effect, suggesting that this effect was increased with increased periods of fermentation.

The present study was performed to assess the worth of using the by products for seaweed (Eucheuma spinosum) ethanol production process (SEPPB) as broiler feeds. For this purpose, 225 broiler chicks (white mini broilers) were used as experimental animals. The control (Control group) was fed with the broiler feeds. 5% mixture (5% SEPPB group) was fed with a 5% SEPPB mixture feeds, and the 10% mixture (10% SEPPB group) was fed with a 10% SEPPB group mixture feeds. The experiment was repeated for five times and 15 birds were assigned in each experiment and the experimental period was five weeks. There was no difference in the rate of weight gain until the second week of the 5% SEPPB group and 10% SEPPB group. However, the weight gain rate was increased to 6.2% for the 5% SEPPB group and 11.4% for the 10% SEPPB group as compared to the Control group at the third weeks of the experimental period. There was no statistical significant difference in terms of feed FCR and feed intake. Analyses of the quality of chicken breasts showed that pH was 2.5% higher in the 5% SEPPB group and 2.3% higher in the 10% SEPPB group. Shearing force was 31.3% lower in the 5% SEPPB group and 14.7% lower in the 10% SEPPB group, while heating loss was 14.4% lower for 5% SEPPB group and 10% SEPPB group when compared to the Control group. No significant differences were observed in terms of moisture, protein, and crude ash components in chicken breast analyses. However, crude fat was 36.8% higher in the 5% SEPPB group when compared to the Control group (P<0.05). Analyses of fatty acid in chicken breast meat showed that stearic acid was significantly higher in the 10% SEPPB group (P<0.05) and linolenic acid was significantly higher in 5% SEPPB group and 10% SEPPB group in comparison to the Control group (P<0.05). Interleukin-2 (IL-2) in blood serum was 44% higher in the 5% SEPPB group and 36% higher in the 10% SEPPB group (P<0.05). Interleukin-6 (IL-6) was similar in both the Control and the 5% SEPPB group, but it was 62% higher in the 10% SEPPB group in comparison to the Control group (P<0.05). Analyses of serum chemical values revealed that albumin was the highest in the 5% SEPPB group, followed by the Control group and then 10% SEPPB group.
The TH cytokine responses of spleen cells stimulated with Con A from mice infected with Polasonimw westemcni were examined. The spleen cell culture supema- tants were assayed for TH1-specific $IFN-{\gamma}$ and TH2-specific IL-4. Cytokine responses for IL-4 peaked at three days ($410{\;}{\pm}{\;}60.9{\;}pg/ml$), persisted at a high level until the second week ($343{\;}{\pm}{\;}59.0{\;}pg/ml$), and then decreased slowly four and six weeks after infection. $IFN-{\gamma}$ production by splenocytes only increased during the first week ($151{\;}{\pm}{\;}32.3{\;}pg/ml$) and declined abruptly after the second week of infection. IFN- y production by splenocytes of infected mice was not observed during the sixth week of infection. In addition, serum IL-4 and $IFN-{\gamma}$ were measured. Serum IL-4 was not detected in substantial quantity until four to six weeks after infection. The time course of serum IL-4 was not correlated with that of IL-4 production by splenocytes. Serum $IFN-{\gamma}$ was undetectable during the entire course of infection. These results suggest that TH2 cytokine responses, rather than TH1, predominate in mice infected with P. westemcni.
