Lung myeloperoxidase (MPO) per unit gram of lung protein. Lung homogenates were prepared as described in materials and methods; results were expressed as MPO U/g lung protein. Lungs collected at 9 h after the LPS treatment had significantly higher MPO compared with all other groups, while both routes of angiostatin treatment had significantly lower MPO compared with the LPS-only group. ^a,b,cDifferent letters indicate statistical differences (P < 0.05) between the groups, while letters that match each other indicate no statistical difference.
