Inflammatory cell contents in aortic lesions from Ldlr−/− mice that consumed 3 months of an atherogenic diet followed by another 3 months of the same diet while receiving daily intraperotoneal administration of DSCG or vehicle alone. Aortic arch lesion Mac-3-positive macrophage content (A), CD4-positive T-cell content (B), MHC class II-positive area (C). Representative images for panels A and C were shown to the left. D. Aortic lesion (including arch, brachiocephalic artery, left common carotid artery, and left subclavian artery) total numbers of HRP-avidin-positive MCs (left) and percentage of activated MCs (right). E. Aortic arch (including adventitia and intima) total numbers of HRP-avidin-positive MCs (left) and percentage of activated MCs (middle). Representative figures on the right showed typical inactive and active MCs from HRP-avidin-stained aortic atherosclerotic lesion sections. The number of mice per group was indicated in each bar.
