Abstract

|
Mahwanghangingamchosukgo-tang (MH) is recorded as a treatment to treat exterior-related respiratory diseases in the Korean medicine. In this study, we examined the anti-inflammatory effects of MH, using MH water extract and lipopolysaccharide (LPS)-induced RAW 264.7 cells. First of all, we measured the amount of nitric oxide (NO) and prostaglandin E2 (PGE2), the products of inflammatory metabolism. Also, we measured enzymes such as inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), as well as cytokines such as interleukin 6 (IL-6), interleukin 1 alpha (IL-1α), and interleukin 1 beta (IL-1β). MH suppressed the production of NO and PGE2 in a dose dependent manner and reduced the amount of protein and the mRNA expression of iNOS and COX-2. Also, MH reduced the mRNA expression of IL-6, IL-1α and IL-1β. In conclusion, MH decreased production of LPS-induced inflammatory factor, which could be a clinical basic subject for inflammatory diseases.
