Hypercholesterolaemia increases neutrophil myeloperoxidase (MPO) expression (A, typical western blots from 3 to 5 rabbits/group), MPO content (B, ELISA results from 8 to 10 rabbits/group), and MPO activity (C, spectrophotometry measurement from 10 to 14 rabbits/group) and their blockade by RSG. Results were expressed as fold change over rabbits fed with a normal diet. ND, normal diet; HC diet, high-cholesterol diet; V, vehicle; RSG, rosiglitazone. The same abbreviations were used for all figures. **P < 0.01 vs. ND + V. ##P < 0.01 vs. HC + V.
