Pathological images of rat arteries from groups A, B, and C. (A) Endothelial cells arranged in order under the vascular intima of group A (×400). (B) There was no obvious proliferation of medial smooth muscle cells in the vascular wall of group A (×200). (C) The morphology of endothelial cells of group B was slightly abnormal (×400). (D) There was no obvious proliferation of medial smooth muscle cells in the vascular wall of group B (×200). (E) Endothelial cells of group C had a foam-like change (×400). (F) Endothelial cells of group C shed from the vessel wall (×400). (G, H) Inflammatory cells accumulated in the vascular intima of group C (×400). (I) Neutrophil granulocytes were seen around the endothelial cells of group C (×400). (J) Mononuclear cells were seen around the endothelial cells of group C (×400). (K) Smooth muscle cells of group C proliferated, thickened, and had no order (×200).
