摘要:

为研究缺氧预适应小鼠脑匀浆提取液对PC12细胞的影响,在PC12细胞培养液中加入缺氧预适应小鼠脑匀浆提取液及其去蛋白提取液,检测缺氧24h和48h后PC12细胞LDH和MTT代谢的变化.结果发现,未去蛋白的脑匀浆组PC12细胞活性显着增加,而去蛋白组细胞活性未见显着变化.提示预适应脑组织中有某种或某些蛋白质类神经保护性物质生成.

Abstract:

To study the protective action of cerebral homogenate extracts on in vitro preparation, the present experiment was conducted on a hypoxic model of PC12 cells. LDH and MTT assay were used to measure changes of the cells′activity following incubation with brain tissue extracts taken from hypoxia preconditioned mice for 24, 48 and 72 h. The cells′activity was found to be significantly increased when the cells were incubated with the extracts containing protein and no significant change was seen when the cells were incubated with protein free extracts. The result indicates that protein like neuroprotective substance(s)is developed in the brain of hypoxia preconditioned mice.

Key words: preconditioning, hypoxia, PC12 cells, MTT assay
