Morphological changes of rat common carotid arteries by E.V.G staining method (magnification ×200). (A) Wistar rats control. (B) Neointimal formation was seen in Wistar rats at day 7 after balloon injury. (C) GK rats control. (D) Visible neointimal formation was observed in GK rats at day 7 after balloon injury. (E) The degree of neointimal hyperplasia expressed by N/M in Wistar and GK rats after balloon injury increased significantly as compared to Wistar and GK rats control, respectively. N/M in GK rats was significantly higher than in Wistar rats. Arrows in images sign neointimal formation after balloon injury. * indicates Wistar control versus Wistar day 7, # indicates GK control versus GK day 7, $ indicates Wistar day 7 versus GK day 7. p<0.01.
