Abstract

목적 : 본 연구는 목향순기탕(木香順氣湯)이 인간의 장관상피세포 계열인 Caco-2 세포에서 항산화작용을 증진시키는 효과가 있는지 검증하기 위한 실험이다. 방법 : 배양된 인간장관 세포계열인 Caco-2 세포에서 세포의 사망은 trypan blue의 소실정도에 의해 평가했으며 $H_2O_2$는 표본산화제로 사용되었다. 결과 : $H_2O_2$에서 노출된 세포들은 용량에 비례하여 세포 사망하는 결과를 보였다. 목향순기탕(木香順氣湯)은 $H_2O_2$에 의해 유발된 세포사망을 방지하였고, 0.05-1%의 농도범위에 걸쳐서 효과가 극대화되었다. 목향순기탕(木香順氣湯)과 강력한 항산화제인 DPPD는 $H_2O_2$에 의해 억제된 SOD의 활성에는 영향을 주지는 못했다. 그러나 $H_2O_2$에 의해 유발된 catalase, glutathione peroxidase, hydroperoxide 탈취효소의 활성이 감소되는 것을 억제하였다. 또한 $H_2O_2$에 의해 유발된 glutathione의 감소는 목향순기탕(木香順氣湯)과 DPPD에 의해 억제되었다. 목향순기탕(木香順氣湯)은 $H_2O_2$에 의해 유발된 ATP의 소실을 회복시켰지만 DPPD는 ATP 소실을 회복시키지 못하였다. 결론 : 이러한 결과로 볼 때 Caco-2세포에서 목향순기탕이 세포사망을 억제하는 것은 다른 기전을 통하여 항산화작용을 하는 것으로 볼 수 있다. 따라서 본 연구는 목향순기탕(木香順氣湯)이 반응성산소기에 의해 유발된 인체 위장관질환의 치료에 사용할 수 있을 가능성을 제시하고 있다.
