选取20只200 g健康SD雌鼠,随机分为4组,每组5只。一组行假手术,其余三组行视神经夹伤术。分别选择视神经夹伤术后7 d、14 d、28 d作为终点,观察视神经节细胞的存活率。
Twenty 200 g healthy SD female mice were selected and randomly divided into 4 groups with 5 mice in each group. One group underwent sham surgery, and the other three groups underwent optic nerve crush surgery. The end points were selected 7 days, 14 days, and 28 days after optic nerve crush operation to observe the survival rate of optic ganglion cells.
