Figure 4: Histological cross-sections of descending aorta in atherosclerotic mice. (a) H&E staining and (b) elastic staining showed that atherosclerotic changes were attenuated in the LPS/Fat+Apa group by apamin. NC, normal control; Apa, normal control treated with apamin; LPS/Fat, LPS injection and high fat dieted mice (atherosclerotic mice); LPS/Fat+Apa, atherosclerotic mice treated with apamin. Scale bars, 50 μm.
