  • Objective: The aim of this study was to investigate the effect of therapeutic ultrasound (US) of cell viability and inflammatory cytokine in rat articular chondrocyte cultures stimulated with lipopolysaccharide (LPS). Design: One group pretest-posttest design. Methods: Cultured chondrocytes were treated with US and/or LPS and assessed for viability, Tumor necrosis factor $(TNF)-{\alpha}$ and Interleukin (IL)-1 production. Results: Oxidative stress was induced in rat chondrocytes with LPS. The cell viability was decreased in chondrocytes after treatment with LPS. The viability revealed that low-intensity pulsed ultrasound (LIPUS) exerted no significant cytotoxicity in the rat chondrocyte. LIPUS inhibited decreased cell viability in the presence of LPS ($30{\mu}g/ml$) in a intensity dependent pattern at LIPUS (p<0.05). $TNF-{\alpha}$ production in the presence of LPS was also inhibited in a dose dependent manner (p<0.05 from $30mW/cm^2$). IL-1 production in the presence of LPS was inhibited as well (p<0.05 from $7.5mW/cm^2$). Conclusions: Our results demonstrate that US was the anti-inflammatory effect of chondrocytes. LIPUS may exert its anti inflammatory effects through inhibition of $TNF-{\alpha}$ and IL-1 synthesis. These results suggest that US have potential for use as a pain relief and reduce the articular destruction.

  • Phellinus linteus (PL), one of the immune-regulatory substances, is recognized to play the role in the metabolic process on inflammation and immunity. It has been traditionally used in the oriental medicine to treat inflammatory related disease. The purpose of this study was to evaluate the effects of water extracts of PL on the mesenteric lymph node lymphocytes immune function in the ICR male mice. Control mice received vehicle only. The PL treated mice were administered the respective extract by oral gavages for 4 weeks. IgE concentrations in serum and MLN lymphocytes were significantly lower in PL treated mice than in control mice. PL increased the proportion of $CD4^+\;and\;CD8^+$ T cells in MLN lymphocytes. PL significantly decreased Th2 cytokine concentrations and mRNA expression levels in cytokine secretions. Therefore, water extracts of PL modulate inflammatory parameters through regulation of immunoglobulin production resulting from decreased Th2 cytokine secretion and mRNA expression levels and reduce pro-inflammatory cytokine secretion and mRNA expression in MLN lymphocytes.

  • 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.

  • Raphanus sativus L. has been reported to have anti-inflammatory and anti-tumor activity. However, the anti-inflammatory effect and mechanism of action of the Raphanus sativus L. seeds (RSS) with or without oil are still unknown. This study was undertaken to investigate the in-vitro anti-inflammatory effect with or without oil in the RSS on RAW 264.7 cells stimulated by lipopolysaccharide (LPS). Results showed the suppressed LPS-induced secretion of pro-inflammatory mediators such as nitric oxide (NO), inflammatory cytokine (IL-6, TNF-α). Additionally, a decrease in protein expression of iNOS was observed, but nuclear translocation of NF-κB p65 was not inhibited. To elucidate the underlying mechanism of the anti-inflammatory effect of RSS, the involvement of mitogen-activated protein kinase (MAPK) signaling pathways was examined. We also found that RSS blocked LPS-induced phosphorylation of c-Jun N-terminal kinase/stress-activated protein kinase (JNK) signaling but did not affect the phosphorylation of p38 MAPK and extracellular signal-regulated kinase (ERK) 1/2. These results suggest that RSS may have potential as an anti-inflammatory agent through the inhibition of LPS-induced inflammatory cytokine production via regulation of the JNK pathway.

  • Coronavirus disease 2019 (COVID-19) is currently a pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 are directly associated with hyper-activation of innate immune response that excessively produce pro-inflammatory cytokines and induce cytokine storm, leading to multi-organ-failure and significant morbidity/mortality. Currently, several antiviral drugs such as Paxlovid (nirmatrelvir and ritonavir) and molnupiravir are authorized to treat mild to moderate COVID-19, however, there are still no drugs that can specifically fight against challenges of SARS-CoV-2 variants. Panax ginseng, a medicinal plant widely used for treating various conditions, might be appropriate for this need due to its anti-inflammatory/cytokine/viral activities, fewer side effects, and cost efficiency. To review Panax ginseng and its pharmacologically active-ingredients as potential phytopharmaceuticals for treating cytokine storm of COVID-19, articles that reporting its positive effects on the cytokine production were searched from academic databases. Experimental/clinical evidences for the effectiveness of Panax ginseng and its active-ingredients in preventing or mitigating cytokine storm, especially for the cascade of cytokine storm, suggest that they might be beneficial as an adjunct treatment for cytokine storm of COVID-19. This review may provide a new approach to discover specific medications using Panax ginseng to control cytokine storm of COVID-19.

  • Vibrio vulnificus, a Gram-negative estuarine bacterium, is the causative agent of food-borne diseases, such as life-threatening septicemia. V. vulnificus penetrating into the intestinal epithelial barrier stimulates an inflammatory response in the adjacent intestinal mucosa. Therefore, interaction between V. vulnificus and intestinal cells is important for understanding of both the immunology of mucosal surfaces and V. vulnificus. In this study we investigated the effects of V. vulnificus infection on cytokine gene expression of human intestinal epithelial cells, Caco-2 and INT-407 cells. (omitted)

  • 미역 물 추출물의 염증 억제 활성을 알아보기 위하여 nitric oxide(NO) 분비량, tumor necrosis factor-alpha (TNF-${\alpha}$), interleukin-6 (IL-6) 및 IL-$1{\beta}$ cytokine 분비량, RAW 264.7 세포의 증식능을 측정하였다. Lipopolysaccharide (LPS)로 염증이 유도된 대식세포의 NO 분비능에 미치는 미역 물 추출물의 영향을 알아보기 위해 대식세포 배양액의 $NO_2{^-}$ 농도를 측정한 결과 NO 분비량이 미역 추출물 농도에 의존적으로 유의적인 감소 경향을 나타내는 것을 확인하였으며, 모든 첨가 농도에서 TNF-${\alpha}$, IL-6 및 IL-$1{\beta}$ cytokine 분비량이 감소하는 것을 확인하였다. 특히 IL-6 cytokine의 경우 첨가물 농도에 의존적으로 유의적인 감소를 보였다. 미역 물 추출물 첨가에 의한 TNF-${\alpha}$, IL-6 및 IL-$1{\beta}$ cytokine 및 NO 분비량의 감소가 세포 사멸에 의한 영향인지를 알아보기 위해 마우스 복강 대식세포에 대하여 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay를 실시하였다. 그 결과 모든 첨가 농도에서 대식세포 증식능이 control에 비해 유의적으로 증가하였다. 따라서 미역 물추출물은 세포사멸에 의해 cytokine 분비량이 감소한 것이 아님을 확인하였으며, 대식세포 증식능을 증가시켜 면역세포를 활성화 시키는 것으로 사료되어진다.

  • Objective : Houttuyniae Herba is widely used in oriental medicine as a remedy for inflammation. However, as yet there is no clear explanation of how Houttuyniae Herba affects the production of inflammatory cytokine. This study was to determine the effects of Essence extracted from Houttuynia cordata Thunb(HCT) on the mast cell-mediated inflammatory responses. Method : We measured the amount of inflammatory cytokine production induced by the phorbol myristate acetate (PMA) plus calcium ionophore(A23187) in the human mast cell line (HMC-1) incubated with various concentrations of HCT. The TNF-$\alpha$, IL-6 and IL-8 secreted protein levels were measured by the ELISA assay. The TNF-$\alpha$, IL-6 and IL-8 mRNA levels were measured by the RT-PCR analysis. Nuclear and cytoplasmic proteins were exmined by Western blot analysis. The NF-$\kappa$B promoter activity was examined by a luciferase assay. Result : HCT inhibited the PMA + A23187-induced TNF-$\alpha$, IL-6 expression and reduced mRNA of TNF-$\alpha$, IL-6 and IL-8. we observed that HCT suppressed the induction of NF-B activity. In addition, HCT suppressed PMA plus A23187-induced NF-$\kappa$B promoting activity. Conclusion : In this study, we have found that HCT is an inhibitor of NF-$\kappa$B and cytokines on the mast cell-mediated inflammatory responses.

  • Interleukin-32 (IL-32), a recently identified pro-inflammatory cytokine, is involved in the pathogenesis and progression of infections, cancer, chronic inflammation, and autoimmune disease. IL-32γ is the most active isoform in cell death and cell activation among nine distinct isoforms of IL-32. IL-32γ potentiates both osteogenic and osteoclastogenic capacities, and is critical in the coupling of bone resorption and bone formation for maintenance of bone homeostasis. IL-32γ is strongly associated with inflammatory bone disorders such as rheumatoid arthritis, ankylosing spondylitis, and osteoporosis. In this review, we summarize current research on the role of IL-32γ in inflammatory bone disorders, highlighting this cytokine as a novel target for prognostic marker and control of these diseases.

  • Kochiae Fructus is a medicinal plant used as medicine of the urinary organs, skin disease and inflammation. In this study, anti-inflammatory activity of Kochiae Fructus extract and its possible mechanisms of action were examined. The anti-inflammatory activity was investigated by inhibition of lipopolysaccharide (LPS) induced nitric oxide (NO), pro-inflammatory cytokine production and matrix metalloprotease-9 (MMP-9) in murine macrophage-like cell line Raw 264.7 cells. The measurement of the induced pro-inflammatory cytokine levels were carried out by ELISA. The phosphorylation of ERK1/2, JNK and MAPK and the nuclear expression of nuclear factor $NF-{\kappa}B$ p65 were investigated by Wesern blot analysis. The extract suppressed the phosphorylation of ERK1/2, JNK, and p38 MAPK, and the nuclear translocation of $NF-{\kappa}B$ p65 in activated cells. As a result, we suggest that the extract of Kochiae Fructus decreased the production of pro-inflammatory cytokines ($TNF-{\alpha}$, IL-6), nitric oxide, MMP-9 in LPS-induced Raw264.7 cells. Kochiae Fructus has possibility to be used as therapeutic benefits against inflammatory diseases.
