Figure 1: Leukocyte recruitment in the femoral artery of ApoE−/− mice fed HF. (a) Snap-shot microphotographs of the intravital microscopy system (IVM) (left, ×200) and their quantification (right graph) (*, **). Arrow heads in microphotographs show adherent leukocytes in the femoral artery. (b) Total cholesterol level and triglyceride level in plasma ofApoE−/− mice fed NC or HF for 2 weeks or 6 weeks (*). (c) Relative mRNA expression levels of VCAM-1 and ICAM-1 in aortas of wt and ApoE−/− mice (*). (d) Leukocyte recruitment in following blockade of VCAM-1 by antibody (*). (e) Microphotograph of the aorta of ApoE−/− mice and wt stained by DHE (×200). (f) mRNA expression of gp91-phox and p22-phox in aorta of ApoE−/− mice (*).
