Abstract

This study was carried out to investigate anti-inflammatory effects of mushroom, Cordyceps militaris. Anti-inflammatory effects analysis was followed by peroxynitrite inhibition activity. Cordyceps militaris mushrooms extracts were screened about inhibition effects of nitric oxide for Raw 264.7 cell treated by lipopolisaccharide(LPS) and inhibition of cyclooxygenase-2(COX-2) for inflammatory effects. In our result, Cordyceps militaris mushrooms were good resource for anti-inflammatory effects and to be followed more research about related anti-inflammatory effects.

밀리타리스 동충하초 추출물은 체내 염증반응을 유도하는 peroxinitrite를 밀리타리스 동충하초 추출물 $128{\mu}g/ml$ 처리로 peroxinitrite를 $60.77{\pm}1.67%$ 저해시켜 뛰어난 저해능을 가지는 것으로 free radical의 생성을 억제하며, Raw 264.7 세포에 LPS $1{\mu}g/ml$을 처리하여 NO 생성이 $3.75{\pm}0.20{\mu}M$까지 증가하였으나 밀리타리스 동충하초 추출물 $32{\mu}g/ml$ 처리군에서 $3.21{\pm}0.10{\mu}M$, $64{\mu}g/ml$ 처리군에서 $3.07{\pm}0.13{\mu}M$로 농도 의존적, 유의적으로 감소 시켰다. 또한, 이로 인해 발현되는 염증 유전자 COX-2의 발현을 유의적으로 저해 한 것을 Western blot으로 확인 하였다. 그러므로, 밀리타리스 동충하초 추출물은 항염증소재로의 가능성이 충분하다고 사료된다.
