Ganoderma applanatum is a medicinal mushroom belongs to Ganodermataceae of Polyporales, Basidiomycota. This study was conducted to evaluate the antioxidant, anti-inflammatory and anti-xanthine oxidase activities of G. applanatum fruiting bodies extracted with methanol. The antioxidant activities were performed on reducing power, 1,1-diphenyl-2-picrylhydrazyl free radical scavenging, and ferrous ion chelating activities. In addition to this, polyphenol and flavonoid contents were aslo analyzed. The methanol extract showed the good reducing power of 3.5 at the concentration of 4.0 mg/ml. The scavenging activity of methanol extract of G. applanatum 1,1-diphenyl-2-picrylhydrazy radicals was better than those of positive control, BHT and tocopherol. The ferrous ion chelating effect of methanol extract was moe effective than those of positive control, BHT and tocopherol. The antioxidant activities of the G. applanatum were increased with the increasing concentration of the extracts. The xanthine oxidase inhibitory activity of methanol extract of G. applanatum was good as positive control, allopurinol. The anti-inflammatory activity of mushroom extract was measured by carrageenan-induced hind paw edema of albino rat. The injection of 50 mg/kg of methanol and hot water extracts significantly reduced the carrageenan-induced paw edema compared with the positive control, indomethacin. The results indicated that fruiting bodies of G. applanatum could be used for natural medicine for anti-inflammatory and anti-xanthine oxidase.

Background: Propionibacterium acnes (P. acnes) is a major contributing factor for the inflammatory reaction of acne. Bee venom (BV) has been traditionally used to the treatment for inflammatory diseases. This study examined the anti-inflammatory effect of BV on P. acnes-induced inflammatory animal model. Methods: P. acnes were intradermally injected into both left and right ear of ICR mice. After injection, different concentrations of BV (1, 10 and 100 μg) mixed with 0.05 g of Vaseline was applied to the surface of the right ears of mice. Results: Histological observation revealed that P. acnes induced a considerable increase in the number of infiltrated inflammatory cells. However, BV treatment showed markedly reduced these reactions. Also, expression levels of TNF-α, and IL-1β were significant reduced in BV treated mice compared with P. acnes injected mice. The binding activity of NF-κB and AP-1 were increased in the P. acnes and Vaseline groups. In contrast, this enhancement of binding activity was markedly withdrawn after treatment with BV. Conclusion: In conclusion, this study indicates that BV has potential as an anti-acne agent and may be useful in the pharmaceutical and cosmetic industries.

Propionibacterium acnes (P. acnes) cause an inflammatory acne that plays an important role in the pathogenesis of acne by inducing inflammatory mediators. Bee venom therapy has been used in oriental medicine for the relief of pain and the treatment of inflammatory diseases. However, a direct effect of bee venom in skin inflammation has not been established. The purpose of this study was to investigate anti-inflammatory properties of bee venom in skin inflammation stimulated by heat-killed P. acnes using human keratinocytes and monocytes cell line. P. acnes stimulates the production of proinflammatory cytokines such as interleukins-1β, -8, interferon-γ and tumor necrosis factor-α in HaCaT and THP-1 cells. Bee venom effectively inhibits the secretion of IL-1β, IL-8, IFN-γ, and TNF-α. P. acnes treatment activates the expression of TLR2, which results in IL-8 expression. However, bee venom treatment reduces the expression of TLR2 and IL-8. Based on these results, bee venom has effects on anti-inflammatory activity against P. acnes in HaCaT and THP-1 cells.

The anti-inflammatory effects of the glycosaminoglycan (GAG) derived from cricket (G. bimaculatus, Gb) were investigated in complete Freund’s adjuvant (CFA) treated chronic arthritis rat model. This GAG produced a meaningful anti-edema effect showing inhibition of C-reactive protein (CRP) and rheumatoid factor. This GAG also inhibited the atherogenesis and pro-inflammatory cytokine levels of VEGF production in HUVEC cells, IL-6, prostaglandin E2 stimulated lipopolysaccharide in LAW 264.7 cells and TNF-α production in normal splenocytes, with dose dependent manner. This GAG was also found to be an inducer of NO production from the HUVEC cells and a stimulator of endothelial nitric oxide synthase. In the histological finding, the LV dorsal root ganglion, linked to the paw treated Gb GAG, was repaired against CFA induced cartilage destruction. The combined Indomethacin (5 mg/kg)-Gb GAG (10 mg/kg) also more effectively inhibited CFA-induced paw edema at 3h, 2nd and 3rd day to levels comparable to anti-inflammatory drug, indomethacin.

Rutin is one of the major flavonoids found in buckwheat (Fagopyrum esculentum Moench). While rutin is already known to exhibit anti-oxidative, anti-inflammatory, and anti-carcinogenic activities. However, the health beneficial function of rutin metabolites is not well understood. In DPPH radical scavenging assays, the present study found that 3,4-dihydroxyphenyl acetic acid had the highest total anti-oxidant activity, followed by 3,4-dihydroxyphenylacetic acid, rutin, homovanillic acid, and 3-hydroxyphenyl acetic acid. Further, 3,4-dihydroxyphenylacetic acid strongly reduced LPS-induced IL-6 production in RAW 264.7 cells, compared with other metabolites. Therefore, these results suggest that rutin metabolites have potential to be utilized as food ingredients with anti-oxidant and anti-inflammatory activities.

아토피성 피부염은 만성 재발성 염증성 피부질환으로 피부장벽기능의 이상과 환경유발인자에 대한 피부과민성과 연관되어 있다. 이전의 연구에서는 아토피성피부염에 효과적인 약용식물 추출물을 발굴하기 위하여 노회, 자회지정, 석류, 석곡 추출물들의 세포독성, 항산화, 항염, 항알레르기 효과를 검토하였다. 본 연구에서는 지질다당류로 활성화시킨 대식세포 RAW26.7 에 대한 약용식물 추출물들의 항염작용을 보다 상세하게 검토하여 항염작용의 근본적인 분자기전을 확인하고자 하였다. 역전사중합효소연쇄반응분석(reverse transcription polymerase chain reaction analysis) 결과, 석류, 석곡, 노회는 염증성 사이토카인인 IL-6 와 IL-1β 유전자발현을 현저하게 억제시켰으며 자화지정은 영향이 없었다. 형질주입과 발광효소분석(transfection and luciferase analysis) 결과, 약용식물 모두가 전사 핵인자 카파비(NF-kB)의 활성화를 억제시켰다. 웨스턴 블럿 분석(western blot analysis) 결과, 노회는 JNK MAP 인산화효소의 활성화를 차단하였지만 p38 MAP 인산화효소의 활성화는 차단하지 못하였다. 반면에 자화지정, 석류, 석곡은 JNK MAP 인산화효소뿐만 아니라 p38 MAP 인산화효소의 활성화도 차단하였다. 이들 실험결과들은 노회, 자화지정, 석류, 석곡은 항염효능을 가지고 있으며 따라서 아토피성 피부염의 증상을 경감 또는 완화시키는 잠재력이 있음을 보여 준다.

꽃송이버섯 추출물은 염증반응 시 유도되는 NO 생성을 저해하는 활성이 있는 것으로 나타났으며, 200 μg/ml의 꽃송이버섯 추출물을 처리하였을 때 NO 저해능이 최대 효과를 보였고 RAW264.7 cell에서는 대조군과 유사한 수준으로 NO 생성을 억제하였다. 이러한 NO 생성의 저해는 iNOS의 발현이 감소한 것에 의한 결과임을 단백질과 mRNA의 발현량 변화를 통하여 확인하였으며, mRNA 발현 변화는 iNOS 유전자의 전사를 담당하는 전사인자인 NF-ĸB와 STAT-1의 활성감소에 의한 결과임을 western blot을 통하여 확인하였다. 특히, NF-ĸB의 활성감소는 IĸBα의 활성증가에 의한 NF-ĸB의 억제능 향상에 의한 것임을 확인하였고, 활성억제된 NF-ĸB가 핵 내부로의 이동이 저해되면서 iNOS 유전자 발현에 영향을 미친 것임을 확인하였다. 그러므로, 꽃송이버섯 추출물은 NO 저해능을 이용한 항염증소재로서 염증성질환의 완하에 도움이 될 것으로 사료된다.

Fraxinus rhynchophylla (Oleaceae), a deciduous tree, is known to have properties that include anti-inflammatory, convergence, febricide, antiblenophthalmia, antidiarrhea, antileukorrhea, and so forth. In addition, it has been used for traditional herbal medicine in East Asian countries, including Korea. In this study, we investigated the antioxidant and anti-inflammatory effects of Fraxinus rhynchophylla ethanol extract (FRE) in lipopolysaccharide (LPS)-induced murine macrophage Raw 264.7 cells with FRE pretreatment. We performed DPPH-assay, Western blot, and Reverse Transcription-Polymerase Chain Reaction (RT-PCR). FRE showed 85% free radical scavenging activity at concentrations of 80 µg/ml. Results of this study also showed that FRE down-regulates Cox-2 and iNOS expression in mRNA and protein level. In conclusion, crude ethanol extract of Fraxinus rhynchophylla exhibited antioxidant and anti-inflammatory activities, and it may potentially provide a valuable source of natural herbal agent to inhibit inflammation.

Flavonoids have a range of biological activities, including anti-allergic, anti-inflammatory, anti-microbial, and anti-cancer activities, as demonstrated by in vitro studies. In this study, we investigated whether luteolin can be applied to suppression of lipopolysaccharide (LPS)-stimulated inflammatory responses in murine macrophages. Luteolin was found to reduce nitric oxide (NO) production in LPS-stimulated Raw 264.7 cells. In addition, expression of inducible nitric oxide synthetase (iNOS), cyclooxygenase-2 (COX-2), and pro-inflammatory cytokine tumor necrotic factor-α (TNF-α) at the mRNA and protein levels were decreased. These inhibitory effects were found to be caused by the blockade of nuclear factor kappa-light- chain-enhancer of activated B cells (NF-κB) activation and phosphorylation of mitogen-activated protein (MAP) kinase family, extracellular signal-regulated kinases 1/2 (ERK1/2), c-Jun N-terminal kinase (JNK), and p38 MAP kinase. In addition, pre-treatment with luteolin resulted in reduced ganglioside expression levels and inhibited expression of GT1b in Raw 264.7 cells. On the basis of these observations, we suggest that luteolin has potential as an anti-inflammatory drug candidate, and ganglioside GT1b may play a role in the inflammatory process.

Likewise, anti-inflammatory activities of extracts was in the range of 60-100 jlg mL-1 and root extract of Geranium sibiricum seemed more useful with 87.38% higher anti-inflammatory activity than shoot with 63.63% activity. Regarding cytotoxicty test against two cancer cell line i.e. SK-Hep1 (liver) and HeLa (uterus), the methanolic extracts of shoot and root of Geranium sibiricum showed the highest toxicity with IC50 values of 10-30 jlg mL-1 and root extract proved more beneficial in this regard. In conclusion, methanolic extract of shoot of Geranium sibiricum had higher antioxidant while root extract had higher anti-inflammatoty and anticancer activities.

Oxidative stress has been reported to be one of causes of neuritis. This study examined antioxidative activities of methanol extracts of six amphibian species known to be medicinal animals (Rana catesbeiana, R. coreana, R. rugosa, R. dybowskii, R. nigromaculata, and Hyla japonica) and investigated their effects of inhibiting nitric oxide (NO) production and cytotoxicity on the murine macrophage RAW264.7 cells. As inflammation is closely associated with reactive oxygen species, assays on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, xanthine oxidase inhibitory activity, superoxide anion radical scavenging activity and NO scavenging activity of the extracts of the six species were performed to investigate their antioxidative activity. The results obtained were as follows; All extracts showed antioxidative activity, and the activity of R. dybowskii was the highest in comparison among those. Anti-inflammatory effects of the extracts were also examined, the five extracts except that of R. rugosa did not show cytotoxicity for RAW264.7 cells at the maximal concentration (1,000 μg mL-1). Selectivity index, meaning NO scavenging activity compared to cytotoxicity, showed the highest level in the extract of R. dybowskii. These results will be very useful basic data for future studies on prevention and treatment of human diseases to understand the biological roles of amphibian extracts throughout the antioxidative or anti-inflammatory pathways.

The anti-inflammatory effect of PHBV/Collagen (PHCP) was examined in a mouse model of lipopolysaccharide (LPS)-induced skin inflammation. Vascular permeability on the back skin was measured by the local accumulation of Evan’s blue dye after subcutaneous injection of LPS (30 µg site^-1 ). Dye leakage in the skin showed a significant increase at 2 h after injection of LPS. This LPS-induced dye leakage was also completely inhibited by HO-1 inhibitor, ZnPP, and antioxidants, including methyl gallate, trolox, and mannitol. To study the possible mechanisms underlying the in vivo anti-inflammatory effect of PHCP against LPS-induced inflammation, we also examined the effects of PHCP on malondialdehyde (MDA) and glutathione levels in skin tissues and found that pretreatment with PHCP resulted in inhibited MDA elevation and a remarkable reduction of glutathione level. In addition, similar results were obtained after pretreatment with antioxidants, including trolox and mannitol, and HO-1 inhibitor, ZnPP. Histopathologically, an influx of neutrophils into the skin dermis was detected between 24 h and 72 h after LPS injection (30, 100 µg site^-1), compared to control animals after injection of saline. This increase was greater in mice treated with 100 µg of LPS than in those treated with 30 µg of LPS and was significantly suppressed by pretreatment with PHCP, antioxidants, and HO-1 inhibitor. These results collectively suggest that PHCP has an anti-inflammatory effect against LPS-induced inflammation model in vivo and may be a good candidate for the skin tissue engineering biomedical application primarily through manipulation of the redox state.
