Methods Cytotoxic activity of CT extract on RAW264.7 cells was evaluated by using 3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide (MTT) solution. Nitric oxide production was measured using Griess reagent system. The total phenolic contents and 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity was measured to evaluate the anti-oxidative effects of CT. Dichlorofluorescin diacetate (DCFH-DA) has been used as a substrate for measuring intracellular oxidant production. Results Cheongajihwang-Tang does not impair the cell viability in tested concentration. CT showed anti-oxidative effects in vitro by decreasing electron donating ability, and also showed anti-inflammatory effects suppressing NO and ROS expression in LPS induced RAW264.7 activation. CT inhibited the generation of intracellular ROS production as dose dependant manner. Conclusions CT has anti-oxidative effects and anti-inflammatory activities. These results indicate that CT extract has an anti-inflammatory activities via anti-oxidative effects.

Lipopolysaccharide (LPS) 는병원균내독소로서인지질, 다당류및소량의단백질로구성되며 RAW264.7 cell 과같은대식세포에서 tumor necrosis factor-alpha (TNFα inflammatory cytokine) 을증가시키며염증을유발한다 33). 또한 reactive oxygen species (ROS) 생성을촉진하고 nitric oxide (NO) 를과도하게활성화시켜염증을유발시켜조직의손상을초래한다 34). 따라서 LPS는염증반응을연구하는실험모델로많이사용되고있다 35). Polyphenol 화합물은 flavonoids, anthocyanins, tannins, catechins, isoflavones, lignanas, resveratrols 등을총칭하며, 식물계에널리분포되어있고과일및엽채류에다량함유되어있다 36). 페놀성항산화제들은연쇄반응에서 alkyl radical이나 alkylperoxy radical에수소를공여하여그 radical 을제거함으로써산화를억제하는작용을가진물질로알려져있다 37). DPPH (1,1-Diphenyl-2-picryl-hydrazyl) 라디컬소거능은항산화제가안정한자유라디칼인 DPPH와반응하면서 DPPH를 DPPHH로환원시켜, 흡광도를감소시키는원리를이용하여항산화활성을측정하는방법으로가장널리사용되고있다 38). Nitric oxide (NO) 는동맥이나다른혈관의이완및신경계의신호전달물질로작용하면서외부에서침입한미 생물에대한방어분자로알려져있다 39). 그러나과도한 NO의형성은혈관투과성부종등의염증반응을촉진시킬뿐만아니라염증매개체의생합성을촉진하여염증을심화시키는것으로알려져있다 40). 본연구에서는靑蛾地黃湯추출물에포함된폴리페놀함량을 gallic acid를표준물질로하여측정한결과, 폴리페놀함량이 39.76±1.63 mg/g으로나타났다. DPPH radical scavenging activity는 CT과양성대조군의전자공여능을농도별로측정하여비교한결과 10 mg/ml 농도에서 33.4±3.7% 의소거능을보여, 양성대조군으로사용한 ascorbic acid 30.3±1.9% 의소거능보다좋은활성을나타내었으며통계적으로유의하였다. NO 생성억제효능을측정한결과본연구에서 LPS 단독으로처리한경우 NO 생성이상승함을확인하였고 CT을농도별로처리한결과농도의존적경향으로 NO 생성을억제하였다. 또한대조군 CT0군의 NO 생성량과비교하였을때통계적으로유의한 NO 생성억제효과를나타내었다. ROS가정상적으로소거되지않았을때는잔존하는자유라디칼에의해산화적스트레스를일으키게된다 41). 세포내생성된 ROS는비형광을나타내는 DCF-DA 를산화시켜형광물질인 DCF로전환시키는데이렇게전환된형광물질의양이 ROS의양을나타낸다 42). 본실험에서역시 LPS에의해유도된 ROS 생성억제효능을측정하기위해 CT을농도별로처리한결과대조군 (CT0) 과비교하여통계적으로유의한그리고농도의존적으로 ROS 생성을억제하였다. 다만, 靑蛾丸과六味地黃湯을연구한논문에서는쥐의신장과뇌조직에서 peroxynitrite (ONOO - ) 의제거능, superoxide dismutase (SOD) 및 glutathione peroxidase (GSH) 와같은항산화효소의활성등을측정하여 12-16) 본실험에서의항산화및항염효과측정방법과달라靑蛾地黃湯과비교분석을할수없는한계점을보인다. 향후연구에서실험방법을통일한다면합방하기전과후의처방효과를비교해볼수있는좋은연구가될것이다. 이상의연구결과를종합하면, 靑蛾地黃湯은항산화효과가있으며이로인한유효한항염증효과를나타내, 염증을동반하여나타나는다양한만성퇴행성질병의연구에응용될수있으리라사료된다. 56 J Korean Med Rehabil 2016;26(3):51-58
