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.

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.

본 연구에서는 말뚝버섯의 자실체 메탄올 추출물의 항산화, cholinesterase 저해 및 항염증 효과를 탐색하였다. DPPH 라디칼 소거능, hydroxyl radical 소거능, 철 이온 제거능 및 환원력 등의 항산화 효과를 측정한 결과 DPPH 라디칼 소거능, hydroxyl radical 소거능 및 환원력은 양성대조군으로 사용한 BHT에 비해 낮았으나 실험에 시용한 2.0 mg/ml의 농도에서 50% 이상의 저해효과를 나타내었고 철 이온 제거능은 BHT에 비해 높게 나타나서 다른 종류의 식의약용 버섯에 비해 항산화 효과가 우수하였다. 치매환자의 기억력 감퇴와 관련된 acetylcholinesterase와 butyrylcholinesterase의 저해실험에서 말뚝버섯 자실체의 메탄올 추출물은 실험에 사용한 전 농도 범위에서 양성대조군인 galanthamine에 비해 유의하게 낮았지만 1.0 mg/ml의 농도에서 50% 이상의 저해 효과를 나타냈다. In vitro 항염증 실험에서 RAW 264.7 대식세포에 서로 다른 농도의 메탄올 추출물을 처리한 후 염증 유발물질인 LPS를 처리하여 RAW 264.7 세포가 생성한 NO의 양을 측정한 결과 추출물을 투여한 실험군의 NO 농도가 LPS만 단독으로 처리한 양성대조군에 비해 유의하게 낮았고 처리한 메탄올 추출물의 농도가 증가함에 따라 생성된 NO의 양은 유의하게 감소하는 경향을 나타났다. 또한 in vivo 항염증 실험에서 먼저 각기 다른 농도의 메탄올 추출물을 생쥐의 뒷발에 주사한 후 추가로 기염제인 carrageenan을 주사하여 흰쥐 뒷발에 유도된 부종 (edema)이 추출물에 의해 저해되는 정도와 염증 치료제로 처방되는 indomethacin을 양성대조군으로 하여 실험을 진행하였다. 실험 결과 흰쥐에 주사한 말뚝버섯 자실체의 메탄올 추출물의 농도가 증가함에 따라 흰쥐 뒷발에 유도된 부종의 용적도 농도 의존적으로 유의하게 감소하는 것이 관찰되어 말뚝버섯 자실체에는 염증을 저해하는 성분이 함유되어 있는 것으로 사료되었다. 따라서 말뚝버섯 자실체의 메탄올 추출물에는 항산화, acetylcholinesterase과 butyrylcholinesterase의 저해 및 항염증 효과를 나타내는 유용 성분이 함유되어 있어 앞으로 의약용 기초 소재로서의 이용 연구가 필요하다고 사료된다.

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.
