Abstract:
Objective To observe the dynamic change of the intimal proliferation in balloon-injured rabbit carotid arteries to explore the mechanism of restenosis. Methods 40 healthy male New Zealand white rabbits were randomly divided into experiment groupsⅠ、Ⅱ、Ⅲ and control group, each group containing 10 rabbits. Right carotid artery was injured with PTCA balloon in the experiment groups. 10 rabbits in each experiment group were killed on 1, 2 and 4 weeks after injury. Morphological change of injured intimae was examined by light microscope and analyzed using a computerized imaging analysis system. Results In experiment group, neointimal areas were significantly more than those in control group(P
