Few changes were observed in lipids and macrophages in plaques. No change in macrophage number in both sexes. Lipid content (A) and macrophage number (B) in the atherosclerotic plaque in the aortic sinus after low-dose arsenic, cadmium, and co-exposure in ApoE^−/−mice. Plaque was quantified in the aortic sinus by oil red O (A) and MOMA-2 (B) staining using ImageJ. Each point represents a single mouse. Statistical significance is represented as follows: *p <. 05.
