Abstract

In this study, the ginsenoside contents and anti-inflammatory effects of white ginseng (WG) and puffed red ginseng (PRG) were compared. The contents of Rb1, Rg5 and Rk1 were significantly higher in PRG than in WG, whereas the contents of Rg1 and Rb2 were decreased in PRG. The levels of NO production and iNOS expression were suppressed in LPS-stimulated cells by treatment with WG and PRG. Further, the production of cytokines (TNF-$\alpha$ and INF-$\gamma$) and inflammatory proteins (NF-${\kappa}B$ and COX-2) was decreased in cells upon treatment with any of the ginsenosides. The high NO inhibitory activity and cytokine production of PRG is caused by differences in the composition of ginsenosides produced.

인삼과 팽화홍삼은 인삼의 가공방법에 따라 구분되어지며, 가공처리과정중 인삼의 효능을 나타내는 사포닌 함량의 변화가 생긴다. 본 연구에서는 인삼과 팽화홍삼을 이용하여 마우스 대식세포인 RAW 264.7세포에서 LPS에 의한 염증에 대한 항염 효과와 그 기전을 규명하고자 하였다. 본 연구를 통해서 인삼과 팽화홍삼 모두 LPS에 의한 NO의 생성을 억제시키는 것을 확인하였으며, TNF-$\alpha$ 및 INF-$\gamma$의 생성 또한 억제시키는 것을 알 수 있었다. 인삼과 팽화홍삼 모두 COX-2의 발현 및 LPS에 의한 $I{\kappa}B$의 인산화를 억제시킴으로써 NF-${\kappa}B$의 활성을 억제시키는 것임을 알 수 있었으나 인삼에 비하여 팽화홍삼의 항염 효과가 더욱 높았다. 그러므로 팽화홍삼이 인삼에 비하여 NO의 생성을 더 효과적으로 억제시키는 것은 팽화가공을 통하여 특정 진세노사이드($Rb_1,\;Rg_5+Rk_1$)의 증가에 의한 것으로 추정된다.
