Objective:To investigate the expressions of vascular endothelial growth factor and microvascular density in benign prostatic hyperplasia, as well as the effects on the angiogenesis of BPH.Metheds:Immunohistochemical S-P assay was used to investigate the expressions of vascular endothelial growth factor and microvascular density in twenty-three cases of BPH.Results:The positive rates of VEGF in the center part and circumjacent part of BPH were 54.35% and 13.48% respectively, and it showed a significant diffe...
