Ultrasound shot-axis views of the right common carotid arteries in ApoE^-/- mice. a normal group, b model group, c low-dose SL group, d medium-dose SL group, e high-dose SL group, and f ATO plus PIO group. The red lines identify the borders of the carotid arteries. The white bar on the bottom of the images represents a scale of 0.5 mm. g Quantitative analysis of the UBM for the plaque area. The results are presented as mean ± SD of five mice per group, ^##P < 0.01: significantly different from the normal group and ^**P < 0.01: significantly different from the model group
