Objectives The object of this study was to assess the effect of Gyejibokryunghwan (GBH) on anti-oxidant and anti-inflammatory activities in RAW 264.7 cells and on factors associated with fracture union in tibia-fractured rats. Methods The 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging activity was measured to assess anti-oxidant activity. The production of nitric oxide (NO), interleukin-6 (IL-6), interleukin-$1{\beta}$ ($IL-1{\beta}$) and tumor necrosis factor-${\alpha}$ ($TNF-{\alpha}$) in the RAW 264.7 cells were measured to assess anti-inflammatory activity. The production of osteocalcin, calcitonin, carboxy-terminal telepeptides of type II collagen (CTXII), transforming growth factor-${\beta}$ ($TGF-{\beta}$), bone morphogenetic protein-2 (BMP-2) in serum of tibia-fractured rats were measured to assess the effects of fracture union. X-rays were taken every two weeks from 0 to 4th week to assess fracture union effect. Results DPPH radical scavenging activity of GBH was increased according to concentration of GBH in RAW 264.7 cell. NO, prostaglandin $E_2$ ($PGE_2$), IL-6, $IL-1{\beta}$ and $TNF-{\alpha}$ were significantly decreased, indicating anti-inflammatory effect. Osteocalcin, calcitonin, $TGF-{\beta}$ were significantly increased in the experimental groups. CTXII was significantly decreased in the experimental groups. BMP-2 was not significantly changed in the experimental groups. The X-ray showed that the experimental group has better healing effects on tibia-fractured rats than control group. Conclusions From above result, GBH has an effect on anti-oxidant, anti-inflammatory activities in RAW 264.7 cells. GBH showed significant results in factors related with fracture union and radiologic examination. In conclusion, GBH can help fracture union and it well be expected to be used actively in clinics.

Dangguisu-san (DGSS) is widely known traditional herbal medicinal formula in Korea for treatment of traumatic injury by traffic accident, ecchymosis, abdominal distension and anti-thrombosis of blood. This study was conducted to develop the simultaneous analyze method using high performance liquid chromatography (HPLC) and examine the effect of anti-inflammatory activity of DGSS-dry extract (DGSS-DE) and DGSS-mix extract powder (DGSS-MEP). Physicochemical characteristics of DGSS-DE and DGSS-MEP showed that there is no significant difference in pH, titratable acidity, total soluble solid content and browning degree except for color value (L, a, b). 15 functional constituents of DGSS were identified and the correlation coefficient values of DGSS-DE and DGSS-MEP were conformed 0.950. Also, DGSS-DE and DGSS-MEP significantly decreased the secretion of nitric oxide (NO), prostaglandin E₂ (PGE₂), interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) through inhibited expression of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), IL-1β, IL-6, and TNF-α. From these result, DGSS-MEP showed similar chemical composition and anti-inflammatory effect to DGSS-DE. Therefore, DGSS-DE and DGSS-MEP may be useful as potential source of drug to prevent inflammation.

Objectives: The purpose of this study is to evaluate anti-breast cancer and anti-inflammatory effects of Chungganhaewool-tang and Shipyeukmiyeugi-eum. Methods: MDA-MB-231 cells were used to measure cytotoxicity, Reactive oxygen species (ROS) production, protein expression amounts of Bcl-2-associated X protein (Bax), B-cell lymphoma 2 (Bcl-2), B-cell lymphoma-extra large (Bcl-xl), Cytochrome C Caspase-3, Caspase-7, Caspase-9, Poly ADP-ribose polymerase (PARP), Nuclear factor erythroid-2-related factor 2 (Nrf2), Heme oxygenase-1 (HO-1) and NAD (P) H Quinone Oxidoreductase 1 (NQO1) to evaluate the anti-breast cancer effects of Chungganhaewool-tang (CHT) and Shipyeukmiyeugi-eum (SYE), and THP-1 cells, differentiated into macrophage and induced inflammation with Lipopolysaccharide (LPS), were used to measure production amounts of ROS, Nitric oxide (NO), and protein expression amounts of Inducible nitric oxide synthase (iNOS), Cyclooxygenase (COX-2), Interleukin-1 beta (IL-1β), Interleukin-6 (IL-6) and Tumor necrosis factor-alpha (TNF-α) to evaluate the anti-inflammatory effects of CHT and SYE. Results: CHT and SYE reduced MDA-MB-231 cell counts, increased protein expression of Bax and Cytochrome C, and decreased protein expression of Bcl-2, Bcl-xl. The protein expression amounts of Caspase-3, 7, and 9 decreased, but amounts of the active form, cleaved Caspase-3, 7, and 9, increased. In addition, PARP protein expression decreased, the amount of PARP protein in the cleaved form increased, and the amount of protein expressions of Nrf2 and HO-1 decreased, but NQO1 showed no significant difference. In THP-1 cells CHT and SYE reduced ROS and NO, and reduced protein expressions of iNOS, COX-2, IL-1, and TNF-α, but only SYE groups reduced IL-6. Conclusions: This study suggests that CHT and SYE have potential to be used as treatments for breast cancer.

Objective : We performed an expanded multi-ethnic meta-analysis to identify associations between inflammation-related loci with intracranial aneurysm (IA) susceptibility. This meta-analysis possesses increased statistical power as it is based on the most data ever evaluated. Methods : We searched and reviewed relevant literature through electronic search engines up to August 2022. Overall estimates were calculated under the fixed- or random-effect models using pooled odds ratio (OR) and 95% confidence intervals (CIs). Subgroup analyses were performed according to ethnicity. Results : Our meta-analysis enrolled 15 studies and involved 3070 patients and 5528 controls including European, Asian, Hispanic, and mixed ethnic populations. Of 17 inflammation-related variants, the rs1800796 locus (interleukin [IL]-6) showed the most significant genome-wide association with IA in East-Asian populations, including 1276 IA patients and 1322 controls (OR, 0.65; 95% CI, 0.56-0.75; p=3.24#x00D7;10^-9) under a fixed-effect model. However, this association was not observed in the European population (OR, 1.09; 95% CI, 0.80-1.47; p=0.5929). Three other variants, rs16944 (IL-1β), rs2195940 (IL-12B), and rs1800629 (tumor necrosis factor-α) showed a statistically nominal association with IA in both the overall, as well as East-Asian populations (0.01<p<0.05). Conclusion : Our updated meta-analysis with increased statistical power highlights that rs1800796 which maps on the IL-6 gene is associated with IA, and in particular confers a protective effect against occurrence of IA in the East-Asian population.

Phellinus igniarius has been clinically used for the treatment of hemorrhoidal fistula, dysmenorrhea and the prevention of cancer in traditional oriental medicine. Recent studies showed that Phellinus igniarius produced anti-cancer, anti-metastasis and immuno-modulatory effects, There is lack of studies regarding the effects of Phellinus igniarius on the immunological activities. The present study was conducted to evaluate the effect of Phellinus igniarius on the regulatory mechanism of cytokines and nitric oxide (NO) for the immunological activities in Raw 264,7 cells. After the treatment of Phellinus igniarius water extract, cell viability was measured by MTT assay, NO production was monitored by measuring the nitrite content in culture medium. COX-2 and iNOS were determined by Immunoblot analysis, and levels of cytokine were analyzed by sandwich immunoassays. Results provided evidence that Phellinus igniarius inhibited the production of nitrite and nitrate (NO), inducible nitric oxide synthase (iNOS), interleukin-1β (IL-1β) and interleukin-6 (IL-6), and the activation of phospholylation of inhibitor κBα (p-IκBα) in Raw 264.7 cells activated with lipopolysaccharide (LPS). These findings suggest that Phellinus igniarius can produce anti-inflammatory effect, which may play a role in adjunctive therapy in Gram-negative bacterial infections.

Objectives: This study investigated the effects of Scutellariae Radix extract (SRE) on lipids metabolism, oxidation and the production of pro-inflammatory cytokines in rats fed highly oxidized fat. Methods: To induce obesity, male Sprague‐Dawley rats were fed a highly oxidized fat diet for 10 weeks. SRE at 100 mg/kg were administered orally to obesity-induced rats for 6 weeks, and their lipid metabolism, oxidation and production of pro-inflammatory cytokines were examined. Results: The concentrations of free fatty acid, triglyceride, total cholesterol, and low density lipoprotein-cholesterol in plasma decreased in SRE-treated groups, although the difference was not significant between control and SRE-treated groups, while that of high density lipoprotein-cholesterol significantly increased in SRE group. The concentrations of total cholesterol and triglyceride in the liver were tended to decrease in SRE-treated group. The concentrations of thiobarbituric acid in plasma and liver were lower in SRE group than in control group. The levels of glutamic oxaloacetic transaminase and glutamic pyruvic transaminase in plasma were decreased in SRE group. Activities of glutathione peroxidase, superoxide dismutase, and catalase in liver were tended to increase in the SRE group. The plasma concentrations of interleukin $(IL)-1{\beta}$, tumor necrosis factor $(TNF)-{\alpha}$ and IL-6 were lower in SRE group than in control group, while that of IL-10 was higher. The liver concentrations of $IL-1{\beta}$, $TNF-{\alpha}$, and IL-6 were tended to decrease while that of IL-10 tended to increase in SRE group. Conclusions: Finally SRE could be used in the production of nutraceuticals for lowering lipids and exerting anti-oxidation and anti-inflammatory effects in obesity rats fed highly oxidized rat.

To elucidate the immuno-stimulatory activity of traditional fermented vinegar, six kinds of crude polysaccharides were isolated from traditional fermented vinegars manufactured with different raw materials in domestic or foreign countries, after which their chemical properties and immuno-stimulatory activities were evaluated. Of the six samples, three kinds of crude polysaccharides prepared from Korean brown rice vinegar (KBV-0), Japanese brown rice vinegar (JBV-0), and Korean persimmon vinegar (KPV-0) showed higher yields and interleukin (IL)-6 production by macrophages and were thus selected for further study. Anti-complementary activities of KBV-0, KPV-0, and JBV-0 increased dose-dependently. KBV-0 and KPV-0 showed higher anti-complementary activities ($ITCH_{50}$ 62 and 65%) than JBV-0 at $1,000{\mu}g/mL$. KBV-0, KPV-0, and JBV-0 did not affect growth of peritoneal macrophages at a dose of 1.6 to $1,000{\mu}g/mL$, where as they significantly augmented production of IL-6, IL-12, and TNF-${\alpha}$ in a dose-dependent manner. However, immuno-stimulatory activity of KPV-0 was the most potent among the tested polysaccharides. These results suggest that Korean fermented vinegars contain selected polysaccharides that confer immuno-stimulatory activities beneficial to human health.

The anaphylactic allergic reaction is involved in many allergic diseases such as asthma and allergic rhinitis. In this report, I investigated the effect of ripe fruits of Rubus coreanus Miq. (Rosaceae) (RFRC) on the anaphylactic allergic reaction and studied its possible mechanisms of action. RFRC inhibited compound 48/80-induced systemic anaphylactic reaction in mice. RFRC dose-dependently decreased the IgE-mediated passive cutaneous anaphylaxis. In addition, RFRC decreased the gene expression and production of tumor necrosis factor-$\alpha$ (TNF-$\alpha$) and interleukin (IL)-6 in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 (A23187)-stimulated human mast cells. These findings provide evidence that RFRC could be a candidate as an anti-allergic agent.

IL-17 is produced by RAR-related orphan receptor gamma t (RORγt)-expressing cells including Th17 cells, subsets of γδT cells and innate lymphoid cells (ILCs). The biological significance of IL-17-producing cells is well-studied in contexts of inflammation, autoimmunity and host defense against infection. While most of available studies in tumor immunity mainly focused on the role of T-bet-expressing cells, including cytotoxic CD8⁺ T cells and NK cells, and their exhaustion status, the role of IL-17-producing cells remains poorly understood. While IL-17-producing T-cells were shown to be anti-tumorigenic in adoptive T-cell therapy settings, mice deficient in type 17 genes suggest a protumorigenic potential of IL-17-producing cells. This review discusses the features of IL-17-producing cells, of both lymphocytic and myeloid origins, as well as their suggested pro- and/or anti-tumorigenic functions in an organ-dependent context. Potential therapeutic approaches targeting these cells in the tumor microenvironment will also be discussed.

The object of this trial was to investigate the effect of dietary ${\beta}$-1,3/1,6-glucan supplementation on the performance and immunological response of broiler chickens. Two hundred and forty 1-day old male broilers ($39{\pm}1g$) were separated into six treatments which were given six different feeds containing 0 (control), 25, 50, 75, 100 and 125 mg/kg dietary ${\beta}$-1,3/1,6-glucan supplementation. On days 21 and 42, body weight gain, feed consumption and feed conversation rate were recorded as measures of growth performance. The levels of key cytokines in the immuno-regulating pathway: interleukin-1 (IL-1), interleukin-2 (IL-2), interferon $\gamma$(IFN-$\gamma$, tumor necrosis factor $\alpha$(TNF-$\alpha$, and the concentrations of signal molecules: peripheral blood plasma globulin, serum Immunoglobulin G (IgG) and intestinal secretary Immunoglobulin A (sIgA), were measured as indices of the immune response to determine suitable levels of dietary ${\beta}$-1,3/1,6-glucan supplementation. The results indicated that performance was elevated quadratically with dietary ${\beta}$-1,3/1,6-glucan supplementation. Maximal growth performance and an enhanced immunological response were obtained at a supplemented level of 50 mg/kg.
