To investigate the therapeutic effect of a Korean herbal medicine Pulsatilla koreana as an anti-septic agent, anti-inflammatory effects of the herbal medicine were determined in lipopolysaccharide (LPS)-exposed rats. Treatment with a methanol extract from Pulsatilla koreana significantly inhibited LPS-induced inflammatory responses. Results from ELISA analysis showed that Pulsatilla koreana decreased the plasma and hepatic levels of pro-inflammatory cytokines such as IL-$1{\beta}$, IL-6, TNF-${\alpha}$ while increased the level of anti-inflammatory cytokine IL-10 in LPS-exposed rats. Pulsatilla koreana also decreased the plasma levels of other inflammatory mediators such as $NO_3{^-}/NO_2{^-}$, ICAM-1, $PGE_2$, and CINC-1 in LPS-exposed rats. Although no significant effects were observed in the phagocytic activities, the distribution of lymphocyte population was significantly shifted by the treatment with Pulsatilla koreana. All together, Pulsatilla koreana exerts anti-inflammatory activities in the immune-challenged animals implicating that this Korean herbal medicine is therapeutically useful for the treatment of inflammatory diseases like sepsis.
