The purpose of this study was to examine the repairing ability of nano-hydroxyapatite (nano-HA) artificial bone with different pore sizes. Animal models of bone defects were created in both radii of 60 New Zealand white rabbits. The bone defects in A, B, and C groups were repaired with nano-HA artificial bone with three different pore sizes while those in(More)
OBJECTIVE To study the protective effects of Schwann cell derived neurotrophic factor (SDNF) on motoneurons of spinal anterior horn from spinal root avulsion induced cell death. METHODS Twenty SD rats were made the animal model of C6.7 spinal root avulsion induced motoneuron degeneration, and SDNF was applied at the lesion site of spinal cord once a week.(More)
OBJECTIVE To observe the degradation of the polylactic glycolate acid (PLGA) microparticles with releasing-slowly vascular endothelial growth factor (VEGF) synthesized by the method of emulsification-diffusion. METHODS The method of emulsification-diffusion is to incorporate VEGF into microparticles composed of biodegradable PLGA. The controlled release(More)
OBJECTIVE To study the clinical outcome of comminuted fractures at distal femur and proximal tibia treated with AO less invasive stabilization systems (LISS). METHODS The clinical data of 14 cases of distal femoral fracture and proximal tibial fracture from September 2003 to May 2005 were analyzed retrospectively. The injury was caused by traffic accident(More)
OBJECTIVE To investigate the quantity and distribution of motor fiber of rat's C7 nerve root. METHODS Motor fiber quantity and section area in the main nerves of the upper extremity and the fascicles of C7 in 30 SD rats were analyzed. RESULTS Fascicles and certain amount (207) of motor fibers from the anterior division of C7 were distributed to(More)
