Macrophage infiltration in the neointimas of the different Zn wires after aortic implantation. (a and b) Staining of the different Zn wires implanted in the rat aortas for 1 month with CD68 or CD206. (c-e) Quantification of CD68⁺ cells, CD206⁺ cells and the ratio of the CD206⁺ cells to the CD68⁺ cells in the neointimas of the different Zn wires. (f) Staining of the different Zn wires implanted in the rat aortas for 1 month with ROS probes or TUNEL. Quantification of areas positive for ROS (g) or TUNEL (h). * indicates p < 0.05, compared between two groups; ** indicates p < 0.01, compared between two groups
