Forty-five adult male Wlstar rats received a neurotomy to bilateral sciatic nerves, which were subsequently reconnected with 10/0 epineurial nylon sutures. The injured segments was locally injected with normal saline （group A）, or 25 μg of phVEGF165 （group B） or 50 μg phVEGF165 （group C）. Nerve conduction and regeneration were evaluated in terms of the histological changes, weight of gastrocnemius muscles, electrophysiology and morphometric results. Our study demonstrated that rats of group C showed the best results in terms of nerve regeneration, followed by group B and group A. Our findings suggested that local injection of phVEGF165 can facilitate nerve regeneration and promote functional recovery in a dose-dependent manner.展开更多
