Inhibitory Effects of Hwanggigunjung-tang on the secretion of PGE2, NO and Cytokines in LPS-stimulated BV2 microglial Cells = 황기건중탕(黃嗜健中湯)이 BV2 microglial cells에서의 염증반응(炎症反應)에 미치는 영향(影向)

국문 초록 (Abstract)

황기건중탕은 보비익기(補裨益氣) 및 거습열(祛濕熱)하는 효능(效能)으로 신체(身體)의 허약(虛弱)을 개선하며 염증(炎症)을 유발할 수 있는 외사(外邪)의 침입을 방어하여 인체의 면역기능(免疫機能)을 강화하는 처방으로 면역관련 세포중 하나인 microglial cell를 대상으로 면역세포에 황기건중탕이 어떠한 효능을 발휘하는 지를 살펴보았다. 물로 전탕(煎湯)한 황기건중탕을 여과한 후 실험한 결과 BV2 microglial cells에서 LPS로 자극하여 염증을 유발하는 주요 물질인 NO의 분비를 세포독성 없이 억제하였다. 또한NO를 생성하는 효소인 Cox-2의 발현도 감소시켰다. 그리고 기타 염증전구 물질들이 $TNF-{\alpha}$, $IL-1{\beta}$, IL-12도 황기건중탕의 용량이 증가함에 따라 의존적으로 감소함을 알 수 있었다. 이러한 결과를 보아 황기건중탕은 면역관련세포인 microglial cell에서 염증 관련 인자들의 분비 및 생성을 억제를 통하여 면역관련 상태를 개선시키는 것으로 사료된다.
