We investigated the effect of sesamol on systemic lipopolysaccharide (LPS)-induced lung inflammation in rats. Sesamol decreased lung edema and injury, significantly decreased LPS-induced cell counts, protein concentration, tumor necrosis factor (TNF)-α, and nitrite levels in bronchoalveolar lavage fluid, and decreased the TNF-α, nitrite, and inducible nitric oxide synthase protein expression in lung tissue. Further, sesamol significantly inhibited LPS-induced TNF-α, nitrite, inducible nitric oxide synthase expression, and nuclear factor-κB activation levels in primary alveolar macrophages. We hypothesize that sesamol attenuates systemic LPS-induced lung inflammation by inhibiting the alveolar macrophage inflammatory response in rats.
