We investigated whether silk fibroin peptide derived from the silkworm, Bombyx mori, could inhibit inflammation and enhance the anti-inflammatory activity of Tat-superoxide dismutase (Tat-SOD), which was previously reported to effectively penetrate various cells and tissues and exert anti-oxidative activity in a mouse model of inflammation. Inflammation was induced by topical treatment of mouse ears with 12-O-tetradecanoylphorbol-13-acetate (TPA). Histological, Western blot, and reverse transcription-polymerase chain reaction data demonstrated that silk fibroin peptide or Tat-SOD alone could suppress elevated levels of cyclooxygenase-2, interleukin-6, interleukin-1beta, and tumor necrosis factor-alpha induced by TPA. Moreover, silk fibroin peptide significantly enhanced the anti-inflammatory activity of Tat-SOD, although it had no influence on in vitro and in vivo transduction of Tat-SOD. Silk fibroin peptide exhibited anti-inflammatory activity in a mice model of inflammation. Therefore, silk fibroin peptide alone or in combination with Tat-SOD might be used as a therapeutic agent for various inflammatory diseases.

This study was carried out to compare the anti-inflammation effects of various fruiting body of Ganoderma species and Cordyceps militaris, Phelinus linteus extracts. We concentrated Ganoderma species and other medicinal mushrooms by extracting with ethanol. And We made it $100{\mu}g/ml$ concentration. As a result of nitrite scavenging activity, in the contrast to the positive control; Ascorbic acid was 25%, ASI 7080 of Ganoderma species was disappeared up to around 40%. And in the contrast to Ascorbic acid was 55%, ASI 7002 was 78.5% that was the highest anti-inflammation effect in the result of "No assay test". The Cordyceps militaris showed 75% and Hericium erinaceus showed 59.7% of anti-inflammation effect. As a result of the fungus yield control test of $TNF-{\alpha}$ through ELISA method to ASI 7002 of Ganoderma species that showed the highest anti-inflammation, it was reduced as same as LPS non-treatment. We extracted RNA from ASI 7002 Ganoderma species 10, 50, $100{\mu}g/ml$ concentration and LPS $10{\mu}g/ml$ of Raw 264.7 cell. And we tested the expression of iNOS, COX-2 and TNF-a that are kinds of inflammation gene after synthesizing RNA with cDNA. Finally we could find that iNOS, COX-2 and TNF-a were all controlled expression in the result of above experiment.

Water and chloroform/methanol extracts of the three local Malaysian snakehead fish, Channa striatus (striped snakehead), Channa micropeltes (giant snakehead) and Channa lucius (blotched snakehead) were evaluated for inhibitory activity in chronic inflammation, using cotton pellet granuloma test. Both water extracts of C. striatus and C. micropeltes showed marked inhibition of the transudative and proliferative components of chronic inflammation (42.9 and 31.2% respectively for C. striatus, 35.6 and 26.2% for C. micropeltes) when compared to those of mefenamic acid (25.1 and 21.3% respectively) and piroxicam (36.1 and 26.2% respectively). The chloroform/methanol extracts did not exhibit any anti-inflammatory effects. These results indicated that C. striatus has more anti-transudative and anti-proliferative activities than the extract of C. micropletes. C. lucius extract in contrast, did not inhibit these two components. This present study indicated the beneficial effects of the water extracts of C. striatus and C. micropeltes, but not C. lucius on chronic inflammation.

Phallus impudicus var. impudicus L. is an edible mushroom that has long been used as folk medicine in China. The aim of this study was to evaluate the antioxidant, anti-cholinesterase, and inflammation inhibitory activities of a methanol extract of fruiting bodies of P. impudicus var. impudicus L. The extract exhibited good 1,1-diphenyl-2-picrylhydrazyl scavenging activity, excellent ferrous ion chelating activity, and moderate hydroxyl radical scavenging activity compared with BHT at 2.0 mg/ml. However, the reducing power of the extract was significantly lower than that the BHT positive control. Although the inhibitory activities of methanol extract on acetylcholinesterase and butyryl cholinesterase were significantly lower than the galanthamine positive control at the concentration tested, the inhibition of acetylcholinesterase and butyryl cholinesterase was 52.83% and 55.17%, respectively, at 1.0 mg/ml. The methanol extract also demonstrated excellent inhibition of inflammation-related activities, such as production of nitric oxide in lipopolysaccharide-induced RAW 264.7 macrophage cells and acute edema induced by administration of carrageenan on the hind paw of rats. The collective results suggest that the fruiting body of P. impudicus var. impudicus L. might be a good source of antioxidant, anti-cholinesterase, and anti-inflammation compounds.

Wogonin (5,7-dihydroxy-8-methoxyflavone) is a down-regulator of cyclooxygenase-2 and inducible nitric oxide synthase expression, contributing to anti-inflammatory activity in vivo. For further characterization of modulatory activity on ploinflammatory gene expression in vivo, the effect of wogonin was examined in this experiment using animal models of skin inflammation. By topical application, wogonin inhibited an edematic response as well as ploinflammatory gene expression against contact dermatitis In mice. Wogonin inhibited ear edema ($19.4-22.6\%$) at doses of $50-200\;{\mu}g$/ear and down-regulated interleukin-$1{\beta}$ induction ($23.1\%$) at $200{\mu}g$/ear in phenol-induced simple irritation. Wogonin ($2{\times}50-2{\times}200{\mu}g$/ear) also inhibited edematic response ($51.2-43.9\%$) and down-regulated ploinflammatory gene expression of cyclooxygenase-2, interleukin-$1{\beta}$, interferon-$\gamma$, intercellular adhesion molecule-1 and inducible nitric oxide synthase with some different sensitivity against picryl chloride-induced delayed hypersensitivity reaction. All these results clearly demonstrate that wogonin is a down-regulator of ploinflammatory gene expression in animal models of skin inflammation. Therefore, wogonin may have potential for a new anti-inflammatory agent against skin inflammation.
