Effects of test samples on infiltration of inflammatory cells in the airway. No pathologic changes in the lungs of the control (A). Mild infiltration of neutrophils and lymphocytes in the submucosa of airways exposed to H-ASD + LPS 1 (B). Moderate infiltration of neutrophils and lymphocytes in the submucosa of airways exposed to H-ASD + LPS 10 (C). Slight eosinophils, neutrophils and lymphocytes in the submucosa of airways exposed to OVA alone (D). Mild to moderate infiltration of the inflammatory cells in the submucosa of airways exposed to OVA + LPS 1 (E) and OVA + LPS 10 (F). Slight infiltration of inflammatory cells in the submucosa of airways exposed to H-ASD + OVA (G). Severe accumulation of eosinophils, neutrophils and lymphocytes in the submucosa of airways exposed to H-ASD + OVA + LPS 1 (H). Moderate to marked infiltration of eosinophils, neutrophils and lymphocytes in the submucosa of airways exposed to H-ASD + OVA + LPS 1 (I) (A–I) HE stain; bar = 20 μm.
