PURPOSE: 1 To build high pressure cell culture model in vitro of RetinalGanglion Cells(RGCs) and observe the RGCs effected by pressure .
目的：1 建立高压体外培养视网膜神经节细胞模型并观察压力对视网膜神经节细胞的影响；
2
The activation of purinergic P2X7 receptor can cause rat retinalganglioncell death and the increase of intracellular calcium.
嘌呤能P 2x7受体激活可导致大鼠视网膜神经节细胞死亡和胞内钙离子浓度升高。
3
Glaucoma is a chronic optic neuropathy characterized by retinalganglioncell death resulting in damage to the optic nerve head and the retinal nerve fiber layer.
