Airway acid induces platelet TF, vWf, and P-selectin expressions. Platelets were isolated from the blood of mice subjected to intranasal saline or acid instillation. Dot plots of single experiments show expression (% of total). The x and y ordinates (gray lines) indicate nonimmune isotype specific IgG label. A: TF and vWf. B: group data, n = 4 mice each bar. C: vWf and P-selectin. D: group data, n = 4 mice each bar. Means ± SE, *P < 0.05 compared with control and saline.
