Inducible nitric oxide synthase (iNOS) are important inflammation enzyme and severe up-nitric oxide (NO) production by this enzyme has been intricated with pathogenesis of inflammation diseases as atopy dermatitis. The present study was designed in order to determine whether Sopungdojeok-san could inhibit atopy dermatitis through modulation of iNOS mRNA expression and NO production, We found that iNOS mRNA expression and NO production in RAW 264.7 macrophages stimulated with lipopolysaccharide dose-dependantly decreased by Sopungdojeok-san extract treatment (0.4 - 1.0 mg/ml). The distribution of iNOS positive reacted cell in atopy dermatitis elicited skin of mice were remarkably decreased by Sopungdojeok-san administration (2.5 ml/kg/day). The SOD ability of Sopungdojeok-san were dose-dependantly increased from 0.6 mg/ ml than butylated hydroxyanisole. These data likely indicate that Sopungdojeok-san may act as inflammatory regulator for atopy dermatitis may be possible to develop useful agent for chemopreventation of NO-intricate inflammatory diseases.

Objective: This experimental study was performed to investigate the anti-inflammation and anti-oxidant effects of Sopungdojeok-tang(SPDJT) and Samulsopung-san(SMSPS) which were used to treat patient with atopic dermatitis Methods: Anti-inflammation and anti-oxidant effects of SPDJT and SMSPS were measured by the inhibitory ability of Nitric oxide(NO) production and the scavenging for 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical. Results: 1. SPDJT and SMSPS were not showed cell toxicity. 2. In inhibitory effects against NO production, all groups of SPDJT were showed anti-inflammation, but all groups of SMSPS were not showed anti-inflammation. There were statistical significances between $20{\mu}g/m\ell$ and 4, $10{\mu}g/m\ell$ in SPDJT groups. 3. In DPPH radical scavenging activity, all groups of SPDJT and all groups of SMSPS were showed anti-oxidant effects. There were statistical significances between $20{\mu}g/m\ell$ SPDJT group and 4, $10{\mu}g/m\ell$ SMSPS groups. Conclusion: These results suggest that the SPDJT groups are better than the SMSPS groups in antiinflammation and anti-oxidant effects.
