Endotoxin causes multiple organ dysfunctions, including acute lung injury (ALI). The current therapeutic strategies for endotoxemia are designed to neutralize one or more of the inflammatory mediators. Accumulating experimental evidence suggests that escin exerts anti-inflammatory and anti-edematous effects. ⋯ The expression of glucocorticoid receptor (GR) level was detected by Western blotting. Pretreatment with escin could decrease the mortality rate, attenuate lung injury resulted from LPS, down-regulate the level of the inflammation mediators, including NO, TNF-α, and IL-1β, enhance the endogenous antioxidant capacity, and up-regulating the GR expression in lung. The results suggest that escin may have potent protective effect on the LPS-induced ALI by inhibiting of the inflammatory response, and its mechanism involves in up-regulating the GR and enhancing the endogenous antioxidant capacity.
