FIG 5. Photomicrographs show cross sections of rabbit CCAs on day 2. Hematoxylin and eosin stain was used. Placement of autologous blood around CCAs induced folding of the endothelial surface, the corrugation of the internal elastic lamina, contraction of smooth muscle cells, and thickening of the arterial wall compared with no blood placement. In the UV-treated vessel, there is less folding of the internal elastic lamina and the smooth muscle cells appear relaxed. Scale bar, 100 µm.

A, VS group.

B, VS + fiber group.

C, Wrap group.

D, Wrap + UV group.

E, VS + UV group.
