Figure 2From: Protective effects of intratracheally administered quercetin on lipopolysaccharide-induced acute lung injuryThe effects of intratracheal administration of quercetin on HO-1 expression in mouse lung. Mice were sacrificed 6 hours after intratracheal administration of quercetin or vehicle. (A) Determination of HO-1 expression by western blotting. Results are shown as the mean ± SD (*p < 0.05) of three independent experiments. (B) Determination of HO-1 expression by immunohistrochemistry. Arrowheads, AMs; black arrows, alveolar epithelial cells; open arrows, bronchial epithelial cells. Original magnification: ×200. Each image is representative of three independent experiments.Back to article page
