This research was performed in order to investigate the anti-inflammatory effects of Bupleuri Radix(BR) on the Immune response in vitro. Cellular proliferation and cytokine production were measured in mast cells or mouse B cells or CD4 Th cells. BR water extract inhibited the secretions of TNF-$\alpha$ and IL-6 in PMA/A23187 stimulated HMC-1 cells. It increased proliferation but did not affect the expressions of CD69 or CD23 in rIL-4/anti-CD40 activated S cells. BR reduced surface IgE expression and secreted IgE but increased the production of IL-4, IFN-$\gamma$ and IgG1 in the same cells. BR caused an increase in proliferation in anti-CD3/anti-CD28 stimulated CD4 Th cells but it did not affect the differentiation of Th1 or Th2 cells. However, IL-2 was increased in BR treated Th2 cells. Considering the above-mentioned results, BR can be applied to a broad range of anti-inflammatory reactions, but our data suggest that it will not be likely to exert any effects on type 1 allergic response.

This study was designed to examine the in vitro antioxidant and anti-inflammatory effects of red beet (Beta vulagaris) root. Red beet root was extracted using 70% ethanol and then fractionated sequentially with n-hexane, ethyl acetate and butanol. Antioxidative ability was evaluated by bioassays using total polyphenol contents and ABTS (2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid diammonium salt) radical scavenging activity. Ethyl acetate fraction of red beet root was best on total polyphenol contents ($37.02{\pm}0.37mg\;GAE/g$) and ABTS radical scavenging effects ($IC_{50}$ $42.9{\pm}9.5{\mu}g/mL$). For the anti-inflammatory activity in RAW264.7 cells, the hexane fraction showed the highest inflammatory effect. Dose response studies were performed to determine the inhibitory effect of hexane fraction of red beet root on pro-inflammatory mediators in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. The hexane fraction of red beet root inhibited the NO and $PGE_2$ production and the protein level of iNOS and COX-2, and protein expression of pro-inflammatory cytokines ($TNF-{\alpha}$, IL-6 and $IL-1{\beta}$), in a dose-dependent manner. These results suggest that red beet root has considerable potential as a functional food ingredient with antioxidative and anti-inflammatory effects.

Shea butter (Vitellaria paradoxa) is a fat extracted from shea tree nuts and contains relatively high levels of non-glycerides. Triterpenes, the main non-glyceride component, exhibit a variety of biological activities such as antitumor, antibacterial, and anti-inflammatory. Shea butter extract (SBE) has been used to treat various skin problems such as burns, eczema, and rash in human medicine, but little is known about the activity of SBE on canine skin. This study evaluated the cytotoxicity and anti-inflammatory effect of SBE in canine keratinocytes. Cytotoxicity of lipopolysaccharide (LPS, 5-50 ng/mL) and SBE (50-200 ㎍/mL) was evaluated using the CCK-8 assay. Non-cytotoxic concentrations of LPS and SBE were administered to canine cell cultures to evaluate anti-inflammatory effects. To evaluate the anti-inflammatory activity of SBE, the levels of IL-1β, IL-8, IL-12, and TNF-α were measured using ELISA kits. The concentration of each cytokine was quantified in control, LPS-treated, LPS + SBE-treated groups. Increased levels of IL-1β, IL-8, and IL-12 were found in LPS-treated groups relative to control groups. LPS + SBE-treated groups showed a lower level of IL-1β, IL-8, and IL-12 than LPS-treated groups. These results suggest that SBE may have application as a topical agent for canine inflammatory skin diseases. However, further in vivo study is needed to evaluate the safety and efficacy of SBE in dogs.

Objectives: The purpose of this study is to evaluate the antioxidant and anti-inflammatory effects of Goryeon-hwan (GRH), which is mentioned in ≪Donguibogam≫ that treats leukorrhea. Methods: In this study, the antioxidant efficacy of GRH was evaluated by measuring the total polyphenol and flavonoid content, DPPH radical scavenging activity, ABTS radical scavenging activity, and ROS production through RAW264.7 cells. The concentration of GRH cytotoxicity was confirmed through the cell viability of RAW264.7 cells, and the production of NO, the production of Cytokine through ELISA assay, and the expression of genes through Real-time PCR were measured to evaluate anti-inflammatory efficacy. Protein phosphorylation and protein expression were measured through Western blot analysis. Results: As a result of the experiment, GRH contained polyphenol and flavonoid, and concentration-dependent increased DPPH radical scavenging activity and ABTS radical scavenging activity and decreased ROS production. The anti-inflammatory efficacy measurement results showed a significant decrease in NO and Cytokine production in the GRH administration group compared to the control group. In terms of gene expression and protein expression, there was a significant decrease in iNOS, COX-2, IL-1β, IL-6, and TNF-α depending on the concentration, and a significant increase in HO-1 and NQO1. Protein phosphorylation measurements showed a concentration-dependent significant decrease in the GRH group at ERK and p38. Conclusions: As a result, the study experimentally confirmed the antioxidant and anti-inflammatory effects of GRH, suggesting that it may be used as a treatment for various gynecological inflammatory diseases including vaginitis.

Periodontitis is generally a chronic disorder characterized by breakdown of tooth-supporting tissues, producing dentition loss. Porphyromonas gingivalis (P. gingivalis), a Gramnegative anaerobic rod, is one of the major pathogens associated with periodontitis. Neutrophils are first line defense cells in the oral cavity that play a significant role in inflammatory response. Xylitol is a known anti-caries agent and has anti-inflammatory effects. In this study, we conducted experiments to evaluate anti-inflammatory effects of xylitol on P. gingivalis infected neutrophils for possible usage in prevention and treatment of periodontal infections. P. gingivalis was intraperitoneally injected and peritoneal lavage was collected for cytokine determination. For in vitro study, neutrophils were collected from mouse peritoneal cells after zymosan injection or bone marrow cells. Neutrophils were stimulated with live P. gingivalis and ELISA was used to determine the effect of xylitol on P. gingivalis induced cytokine production. $IL-1{\beta}$, IL-6, $TNF-{\alpha}$ concentration and neutrophil population in the peritoneal lavage was increased in P. gingivalis-infected mouse. Peritoneal cells infected with live P. gingivalis revealed significantly increased production of $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ at multiplicity of infection of 10. Neutrophils from bone marrow and peritoneal lavage revealed increased production of $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$. Xylitol significantly mitigated P. gingivalis induced cytokine production in neutrophils. Findings indicate that xylitol is an anti-inflammatory agent in neutrophils infected with live P. gingivalis, that suggests its use in periodontitis management.

Berberine is an isoquinoline alkaloid found in Rhizoma coptidis, and elicits anti-inflammatory effects through diverse mechanisms. Based on previous reports that activating transcription factor-3 (ATF-3) acts as a negative regulator of LPS signaling, the authors investigated the possible involvement of ATF-3 in the anti-inflammatory effects of berberine. It was found berberine concentration-dependently induced the expressions of ATF-3 at the mRNA and protein levels and concomitantly suppressed the LPS-induced productions of proinflammatory cytokines ($TNF-{\alpha}$, IL-6, and $IL-1{\beta}$). In addition, ATF-3 knockdown abolished the inhibitory effects of berberine on LPS-induced proinflammatory cytokine production, and prevented the berberine-induced suppression of MAPK phosphorylation, but had little effect on AMPK phosphorylation. On the other hand, the effects of berberine, that is, ATF-3 induction, proinflammatory cytokine inhibition, and MAPK inactivation, were prevented by AMPK knockdown, suggesting ATF-3 induction occurs downstream of AMPK activation. The in vivo administration of berberine to mice with LPS-induced endotoxemia increased ATF-3 expression and AMPK phosphorylation in spleen and lung tissues, and concomitantly reduced the plasma and tissue levels of proinflammatory cytokines. These results suggest berberine has an anti-inflammatory effect on macrophages and that this effect is attributable, at least in part, to pathways involving AMPK activation and ATF-3 induction.

Objectives: The object of this study was to identify the anti-inflammatory effects of Patrinia scabiosaefolia aqueous extract (PSE). Methods: RAW 264.7 cells were pre-treated with PSE and then incubated with or without lipopolysaccharide (LPS). Cell viability, production of nitric oxide (NO), secretion of pro-inflammatory cytokine, activation of mitogen-activated protein kinases (MAPKs) and nuclear factor-kappa B (NF-${\kappa}B$) were measured. In addition, we observed mice survival rate after LPS and their cytokine levels of serum. We also observed inflammatory and hemorrhagic change on the histological sections of the liver. Results: PSE inhibited LPS-induced NO production, interleukin (IL)-6 secretion, c-Jun NH2-terminal kinase (JNK) and NF-${\kappa}B$ activation. In addition, PSE reduced the death rate of LPS-induced mice and IL-6 production on the serum of mice. PSE inhibited inflammation and hemorrhage on liver tissue as well. Conclusions: The results suggest that PSE have anti-inflammatory effects by inhibited NF-${\kappa}B$ and JNK activation, IL-6 secretion, and NO production. So PSE may be effective treatment for the inflammatory disease.

Purpose: This study was performed to evaluate the anti-inflammatory effect of Eungapbang extract (EGB). Methods: To evaluate the anti-inflammatory effects of EGB, we nourished RAW 264.7 cell lines in the laboratory dish. Next, inflammatory cytokine concentrations were analyzed. Then, sera were prepared from blood after lipopolysaccharide (LPS) injection in chemically induced mouse models of intestinal inflammation, and Interleukin-1${\beta}$ (IL-1${\beta}$), interleukin-6 (IL-6) and tumour necrosis factor alpha (TNF-${\alpha}$) were measured using ELISA kits. Results: 1. EGB significantly suppressed the expression levels of IL-1${\beta}$ and NOS-II genes at 100, 50 and 10 ${\mu}g/m{\ell}$ concentrations, and IL-6, TNF-${\alpha}$ and COX-2 mRNAs at 100 and 50 ${\mu}g/m{\ell}$ concentrations. 2. EGB significantly reduced the production level of IL-1${\beta}$ and TNF-${\alpha}$ at 100${\mu}g/m{\ell}$ concentrations, and IL-6 at 100 and 50 ${\mu}g/m{\ell}$ concentrations. 3. EGB significantly decreased the production level of IL-1${\beta}$ and IL-6 in sera of acute inflammation induced mice. 4. EGB could suppress the expression level of IL-1${\beta}$ and IL-6 mRNA in spleen tissues in acute inflammation induced mice. Conclusion: On the basis of the above results, it is confirmed that the anti-inflammatory effects of EGB were recognized. Therefore, EGB is recommended as promising therapy for treatment of such ailments as pelvic inflammatory disease.
