Objective To establish a rabbit model of restenosis and analyze the expressions of VEGFmRNA and TGF-?_1mRNA during the intimal proliferation.We also explored the relationship between VEGFmRNA,TGF-?_1mRNA and restenosis.Methods 40 healthy male New Zealand white rabbits were evenly divided into three injury groups and one control group.Right carotid arteries were injured with PCI balloon in the injury groups.10 rabbits of each injury group were sacrificed on weeks 1,2 and 4 after the injury.VEGFmRNA and TGF-?_1mRNA were examined by in situ hybridization.All the samples were analyzed using a computerized imaging analysis system.Results In the injury groups,neointimal areas were significantly larger than those in control group(P
