Objective: This research aimed to study the effects of Artemisia argyi flavonoids (AAF) supplemented in diets on the growth performance and immune function of broiler chickens challenged with lipopolysaccharide (LPS). Methods: A total of one hundred and ninety-two 1-d-old broiler chicks were assigned into 4 treatment groups, which were, respectively, fed a basal diet (control), fed a diet with 750 mg/kg AAF, fed a basal diet, and challenged with LPS, fed a diet with 750 mg/kg AAF, and challenged with LPS. Each treatment had six pens with 8 chicks per pen. On days 14, 16, 18, 20 (stress phase I) and 28, 30, 32, 34 (stress phase II), broilers were injected with LPS (500 ㎍/kg body weight) or an equivalent amount of saline. Results: The results demonstrated that dietary AAF significantly improved the body weight (d 21) and alleviated the decrease of average daily gain in broilers challenged with LPS on d 21 and d 35 (p<0.05). Dietary AAF increased bursa fabricius index, and dramatically attenuated the elevation of spleen index caused by LPS on d 35 (p<0.05). Furthermore, serum interleukin-6 (IL-6) concentration decreased with AAF supplementation on d 21 (p<0.05). Diet treatment and LPS challenge exhibited a significant interaction for the concentration of IL-1β (d 21) and IL-6 (d 35) in serum (p<0.05). Additionally, AAF supplementation mitigated the increase of IL-1β, IL-6 in liver and spleen induced by LPS on d 21 and 35 (p<0.05). This study also showed that AAF supplementation significantly reduced the expression of IL-1β (d 21) and nuclear transcription factor kappa-B p65 (d 21 and 35) in liver (p<0.05), and dietary AAF and LPS treatment exhibited significant interaction for the gene expression of IL-6 (d 21), toll like receptor 4 (d 35) and myeloid differentiation factor 88 (d 35) in spleen (p<0.05). Conclusion: In conclusion, AAF could be used as a potential natural immunomodulator to improve growth performance and alleviate immune stress in broilers challenged with LPS.
Atractylodes macrocephala is a perennial herb and is a member of the Compositae family. This plant is known to contain various bioactive constituents indicating anti-inflammatory, neuroprotective, anti-oxidant, immunological enhancement, and gastroprotective effects. In this investigation, we isolated four compounds with similar chemical structures from A. macrocephala, and evaluated their anti-inflammatory effects. Among the four compounds, compound 2(atractylenolide II) showed the second-best inhibitory effect on the lipopolysaccharide(LPS)-induced production of nitric oxide in RAW264.7 macrophages and BV2 microglial cells. Compound 2 also inhibited the LPS-induced the production of prostaglandin E2(PGE2), and the expression of inducible nitric oxide synthase(iNOS) and cyclooxygenase(COX)-2 proteins in both cells. In addition, compound 2 suppressed the production of pro-inflammatory cytokines including interleukin(IL)-1β, IL-6, and tumor necrosis factor(TNF)-α. These inhibitory effects were contributed by inactivation of nuclear factor kappa B(NF-κB) and mitogen-activated protein kinases(MAPKs) pathways by treatment with compound 2. This compound did not induce the expression of heme oxygenase(HO)-1 protein indicating that the anti-inflammatory effect of compound 2 was independent with HO-1 protein. Taken together, these results suggested that atractylenolide II can be a candidate material to treat inflammatory diseases.

Objectives : This study was to evaluate the anti-inflammatory and anti-pruritic effects of WSY-1075 composited with Corni Fructus, Angelica gigantis Radix, Lycii Fructus, Ginseng Radix, Cervi parvum Cornu and Cinnamomi Cortex in rat peritoneal mast cells (RPMCs) and scratching mouse model. Methods : WSY-1075 was prepared by extracting with 30% ethanol. In the present study, we investigated the effect of WSY-1075 on the production of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$) and histamine in rat peritoneal mast cells (RPMCs) activated with phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187, and on the scratching behavior in mice treated with pruriogens. Results : WSY-1075 was not cytotoxic effect in used all concentration. PMA plus A23187 treatment significantly increased TNF-${\alpha}$, IL-$1{\beta}$ and IL-6 production compared with media control in RPMCs. However, TNF-${\alpha}$, $IL1{\beta}$ and IL-6 production increased by PMA plus A23187 treatment were significantly inhibited by WSY-1075 (200 ${\mu}g/mL$ and 400 ${\mu}g/mL$). WSY-1075 also inhibited the histamine release from RPMCs stimulated by compound 48/80, which promotes histamine release. Moreover, WSY-1075 administration had an inhibitory effects on the scratching behavior induced by pruritogen (compound 48/80, histamine, serotonin and substence P) in ICR mice. Conclusion : These results suggest that WSY-1075 administration (200 mg/kg or 400 mg/kg) has the anti-inflammatory and anti-pruritic effects on the activated rat peritoneal mast cell and mouse pruritus. WSY-1075 has a potential use as a composition of medicinal plants for treatment against inflammation- and pruritus-related disease.

Objectives : Osteoarthritis is characterized by degeneration of articular cartilage, which is characterized by chronic pain, stiffness and decrease range of motion. The present study was designed to compare the therapeutic effect of Dioscoreae Rhizoma water extract (DRW) and Dioscoreae Rhizoma 30% ethanol extract (DRE) on the monosodium iodoacetate (MIA)-induced osteoarthritis rats. Methods : Osteoarthritis was induced by injection of MIA ($50{\mu}{\ell}$ with $80mg/m{\ell}$) into the knee joint cavity of rats. After adaptation period for seven days, rats were divided by 5 groups (n=10/group): normal group, control group, positive control (indomethacin 5 mg/kg), DRW 200 mg/kg treated group, DRE 200 mg/kg treated group (n=10/group). The hind paw weight distribution was measured with the changes of reactive oxygen species (ROS), peroxynitrite ($ONOO^-$) in articulation tissue. Also, the cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), tumor necrosis factoralpha ($TNF{\alpha}$), interleukin-6 (IL-6), matrix metalloproteinase-1 (MMP-1), and tissue inhibitor of metalloproteinases-1 (TIMP-1) were investigated by western blot analysis. Results : The administration of DRW and DRE significantly decreased the hind paw weight distribution. The ROS and $ONOO^-$ levels of cartilaginous tissue were significantly decreased in DRW and DRE compared to control group. The results showed that DRE decreased inflammatory cytokines such as iNOS and $TNF{\alpha}$. Also DRE decreased MMP-1 and increased TIMP-1. Conclusions : Based on the above results, Dioscoreae Rhizoma extract seems to have the therapeutic effect on osteoarthritis via suppression of inflammation.

Earthing, caused by direct skin contact with the Earth's surface, is used to reduce the symptoms of inflammation (fever, fever, swelling and pain). However, there is little evidence to support the anti-inflammatory effects of earthing mattresses. Therefore, this study was conducted to investigate whether anti-inflammatory effect of earthing mattress using an in vivo animal model. The anti - inflammatory effect was evaluated by measuring ear thickness and foot volume in 12-O-tetradecanoylphorbol-13 acetate (TPA) - induced ear edema and carrageenan - induced paw edema model, respectively. Balb/c mouse in carrageenan paw edema model showed significant anti - inflammatory effect in the group treated with earthing mattress for 4 hours or 24 hours for 3 days. For females, the anti-inflammatory effect was greater when the earthing mattress was added to the mattress than the mattress alone treatment. From the above results, it was found that the female responds more to the effect of the earthing as well as the mattress effect. In addition, when the male and female Balb/c mice were exposed to mattresses and earthing mattresses for 24 h for 3 days, respectively, the mattress and earthing mattresses showed significant inhibition of IL (Interleukin)-1β levels compared to the control. In the TPA ear edema model, Balb/c mouse showed significant anti - inflammatory effect in the group treated with the earthing mattress for 4 hours or 24 hours for 3 days. Both males and females showed more anti-inflammatory effects when they were exposed to earthing mattresses with mattresses added to the mattresses. From the above results, it was found that both male and female respond to the effect of earthing as well as the mattress effect in the TPA ear edema model. In conclusion, in this study, we have verified that earthing mattress shows inhibitory effects on TPA and carrageenan-induced inflammation. From these results, it is suggested that the anti-inflammatory effect can be expected by applying the earthing mattress to patients suffering from inflammatory diseases. However, there is a need to pinpoint exactly how the earthing mattress relieves inflammation, and further research is needed to investigate the mechanism.
The effect of Saccharomycopsis fibuligera fermentation on the antioxidant and anti-inflammatory activity of Kerria japonica (K. japonica) extracts was studied. First, the antioxidant activity of the fermented extract was measured using the 2,2-diphenyl1-picrylhydrazyl (DPPH) and 2,2'-azinobis (3-ethylbenzthiazoline 6-sulfonic acid (ABTS) methods. Also, the quantification of polyphenols and flavonoids, which are representative components with antioxidant activity, was performed. The results of the DPPH and ABTS assays showed an increase in the antioxidant activity by 14.39% and 21.74%, respectively, due to fermentation. The polyphenol concentration increased by 10.5%, and the flavonoid concentration increased by 100.0%. In the cell experiment, a cytotoxicity test and a nitric oxide (NO) production inhibitory test were performed using RAW 264.7 cells. Both the control group and the fermentation group showed no cytotoxicity. In the NO production inhibition experiment, the fermentation group showed a 6.85% higher inhibition of NO production compared to the control group. When the inhibitory effects of the extracts on inflammatory cytokine production were assessed, the fermentation group showed 12.4% and 23.5% higher inhibition of interleukin (IL)-1β and IL-6 production, respectively, compared to the control group. In conclusion, due to its potential for inhibiting NO and inflammatory cytokine production, fermented K. japonica extracts could be considered a source of anti-inflammatory compounds.

Objective: The highly pathogenic avian influenza virus (HPAIV) is a threat to the poultry industry as well as the economy and remains a potential source of pandemic infection in humans. Antiviral genes are considered a potential factor for HPAIV resistance. Therefore, in this study, we investigated gene expression related to cytokine-cytokine receptor interactions by comparing resistant and susceptible Ri chicken lines for avian influenza virus infection. Methods: Ri chickens of resistant (Mx/A; BF2/B21) and susceptible (Mx/G; BF2/B13) lines were selected by genotyping the Mx dynamin like GTPase (Mx) and major histocompatibility complex class I antigen BF2 genes. These chickens were then infected with influenza A virus subtype H5N1, and their lung tissues were collected for RNA sequencing. Results: In total, 972 differentially expressed genes (DEGs) were observed between resistant and susceptible Ri chickens, according to the gene ontology and Kyoto encyclopedia of genes and genomes pathways. In particular, DEGs associated with cytokine-cytokine receptor interactions were most abundant. The expression levels of cytokines (interleukin-1β [IL-1β], IL-6, IL-8, and IL-18), chemokines (C-C Motif chemokine ligand 4 [CCL4] and CCL17), interferons (IFN-γ), and IFN-stimulated genes (Mx1, CCL19, 2'-5'-oligoadenylate synthase-like, and protein kinase R) were higher in H5N1-resistant chickens than in H5N1-susceptible chickens. Conclusion: Resistant chickens show stronger immune responses and antiviral activity (cytokines, chemokines, and IFN-stimulated genes) than those of susceptible chickens against HPAIV infection.

Objectives This study was conducted to confirm the anti-inflammatory effect of Naetakbaekryeom-san (NTB), and whether it could be another treatment for inflammatory diseases. Methods The NTB water extract was extracted with hot water at 100℃ for 2 hours, concentrated at 80℃ under reduced pressure, and used. After 2 hours of pretreatment with NTB and positive control Bay11-7082, nitric oxide (NO), inducible NO synthase (iNOS), interleukin (IL)-6, IL-1𝛽, tumor necrosis factor alpha (TNF-𝛼) were measured in RAW264.7 cells activated with lipopolysaccharides (LPS) 500 ng/mL. After 2 hours of pretreatment with NTB, the anti-inflammatory effect of NTB was evaluated by measuring nuclear factor kappa-light-chain-enhancer of activated B cells (NF-𝜅B) in RAW264.7 cells and 293T cells activated with phorbol 12-myristate 13-acetic acid (PMA) 30 ng/mL. Results In RAW264.7 cells activated with LPS, NTB at concentrations of 0.1, 0.3, and 1.0 mg/mL showed no cytotoxicity, significantly inhibited NO production and inhibition of iNOS expression. TNF-𝛼 cytokine levels was not regulated, but NTB at each concentration inhibited the production of IL-1𝛽 and IL-6, and the effect was higher than that of the positive control Bay11-7082 (20 𝜇M). In PMA-activated RAW264.7 cells and 293T cells, each concentration of NBT decreased the NF-𝜅B transcriptional activity, with the greatest decrease at 1 mg/mL. Conclusions These results demonstrated the anti-inflammatory effect of NTB water extracts, but further studies such as comparison of anti-inflammatory effects and antioxidant effects by NTB component, comparison of effects according to extraction solvents, and clinical studies are needed.
Antioxidant, cytotoxic, and anti-inflammatory assays were conducted to determine the commercial viability of Brachythecium populeum. The antioxidant activity was assessed by performing the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-Azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays. This was followed by the quantification of polyphenols and flavonoids. Results of the DPPH and ABTS assay showed that antioxidant activities of the ethanol extract of B. populeum were 3.7 and 3.6 times higher than water extract, respectively. The polyphenol concentration was also determined to be 4.1 times higher and the flavonoid concentration was 5.3 times higher than the water extract. The cell-based experiments, 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT) assay and nitric oxide assay, were performed using RAW 264.7. Results of the MTT assay revealed that both extracts exerted no cytotoxicity on the cells (based on 80% viability). In the nitric oxide (NO) production inhibition experiment, inhibition of NO production was determined to be 15.42% more when exposed to ethanol extract as compared to water extract. Furthermore, the ethanol extract exerted greater inhibition of inflammatory cytokines interleukin (IL)-1β, IL-6, and tumor necrosis factor-α production (9.39%, 11.87%, and 14.49% more, respectively) when compared to the water extract. Due to the good antioxidant activity and potential for inhibiting NO and inflammatory cytokine production, B. populeum ethanol extracts are prospective sources of anti-inflammatory compounds.

Objective: The objective of this study was to determine whether dietary supplementation with a functional fatty acid blend (FA) that contains 31.4% butyric acid and 4.99% medium-chain FA improve growth performance, antioxidant capacity, immunity status, and anti-inflammatory ability in weaned piglets. Methods: One hundred and forty-four healthy piglets (Duroc×Landrace×Yorkshire) with an average body weight (BW) of 7.98±3.43 kg were randomly divided into three groups with six replicate pens and eight piglets per pen: Normal control (NC): a corn-soybean basal diet; FA1: a basal diet supplemented with 1,000 mg/kg of a functional FA; FA2: a basal diet supplemented with 2,000 mg/kg of a functional FA. The experiment lasted for 28 d. On d 14 and 28, one piglet in each pen from NC and FA2 groups was randomly selected for antioxidative index and immunoglobulins. On d 28, one piglet in each pen from NC and FA2 groups was randomly selected for intestinal morphology and inflammatory factor. Results: We observed that FA supplementation linearly increased (p<0.05) average daily gain and the final BW. There was higher (p<0.05) catalase on d 14, and immunoglobulin (Ig) A and IgM on d 28 in piglets supplemented with FA2 than in the NC group. Moreover, dietary FA2 reduced (p<0.05) crypt depth of ileum in piglets. The concentrations of tumor necrosis factor-α, interleukin (IL)-1β, IL-8, and IL-10 in jejunum were lower (p<0.05) in the FA2 group compared with the NC group. Conclusion: Therefore, the overall results suggests that the FA may help to improve gut health, antioxidant status, and immune parameters resulting in the improvement of growth performance.
