| 摘 要： | 目的 观察重复低氧对小鼠海马组织内血管内皮生长因子(vascular endothelial growth factor,VEGF) 蛋白质表达的影响.方法 小鼠随机分为3组，分别暴露低氧0次(H0),1次(H1),4 次(H4)后取海马组织,应用 Western Blot 技术,检测小鼠海马组织内VEGF的蛋白表达变化.结果 实验发现，H0,H1和H4组海马组织内VEGF均表达，H1组与H0组之间没有差异，H4组显著升高（P<0.05，vs. H0 and H1）.结论 VEGF在急性低氧预适应小鼠海马组织表达增加可能参与预适应的形成及脑保护.

| Abstract: | Objective:To detect the effect of hypoxia preconditioning on vascular endothelial growth factor(VEGF) expression in acute repeated hypoxic mice hippocampus.Methods:Mice were divided into 3 groups randomly and were exposed to hypoxia for 4 runs(H4 group),1 run(H1 group) and 0 run(control group).Western Blot was used to examine the VEGF level in mice hippocampus following exposure to hypoxia.total protein was extracted from mice hippocampus for Western blot.Results:VEFG were found in H0,H1 and H4 group.VEGF protein levels were found to be increased markedly in H4(P<0.05,vs.H1 and H0).There is no difference between H1 and H0.Conclusion: The change of VEGF protein level is closely related to protection of the brain and the formation of preconditioning in hypoxic preconditioned mice. |
