Povidone-iodine (PVI) treatment promoted wound neovascularization. (A) Representative immunohistochemical CD34 stained wound sections from a control and PVI treated rat. Scale bar = 50 μm. (B) Semi-quantitative analysis of capillary density (/mm2). Capillary density was assessed by counting the number of CD34 positive microvessels in high-power fields (40x). *p < 0.05, **p < 0.01 vs control. Data are means ± S.D, n = 24.
