Na+-K+ ATPase expressions in the peri-infarct zone and contralateral hemisphere, including the hippocampus. Two days after hypoxic ischemia, Na+-K+ ATPase immunoreactivity was significantly enhanced in the contralateral cortex and was maintained up to 7 days after ischemia, whereas Na+-K+ ATPase immunoreactivity in the peri- and infarct zones was unaffected by hypoxic ischemia. In contrast, 2 to 7 days after ischemia, MAP1A and MAP2 immunoreactivity in the ipsi- and contralateral cortex significantly decreased, whereas in layer V, MAP1 immunoreactivity obviously accumulated in the neurons and their processes. In the hippocampus, 2 days after insults both MAP1A and MAP2 immunoreactivity was significantly reduced within the ipsi- and contralateral hippocampus. In the contralateral hippocampus, however, the distribution of MAP2 immunoreactivity recovered to the sham level 7 days after ischemia, whereas MAP1A immunoreactive axons remained 2 months after ischemia. The results suggest that the unilateral elevation of Na+-K+ ATPase immunoreactivity reflects elevated neuronal activity. In addition, this asymmetric hyperexcitability might play an important role in the recovery or the reorganization of the brain, accompanied by transcortical changes in MAPs expression."> 联接改变Na + - k + atp酶和Microtubule-Associated蛋白免疫反应性大鼠皮质萎缩引起的缺氧缺血模型 - raybet雷竞app,雷竞技官网下载,雷电竞下载苹果

联接改变 Na + - - - - - - K + 腺苷三磷酸酶和Microtubule-Associated蛋白免疫反应性大鼠皮质萎缩引起的缺氧缺血模型

文摘

确定先后顺序联接的改变侧半球后缺血性侮辱,我们调查了微管相关蛋白(MAP)和变化 Na + - - - - - - K + 腺苷三磷酸酶表达peri-infarct区和侧半球,包括海马体。缺氧缺血后两天, Na + - - - - - - K + 侧皮层的atp酶免疫反应性明显增强,并维持缺血后7天,而 Na + - - - - - - K + atp酶免疫反应性在邻近和梗塞区受到缺氧缺血的影响。相比之下,缺血后2 - 7天,MAP1A和MAP2免疫反应性ipsi -和侧皮层明显下降,而在第五层,MAP1免疫反应性明显积累在神经元和他们的流程。在海马体,2天后侮辱MAP1A和MAP2免疫反应性显著降低在ipsi侧海马。然而,在侧海马的分布MAP2免疫反应性缺血后恢复7天的虚假的水平,而MAP1A免疫反应性的轴突仍缺血后2个月。结果表明,单边海拔 Na + - - - - - - K + atp酶免疫反应性反映了高架神经元活动。此外,这种不对称超兴奋性可能发挥重要作用在大脑的恢复或重组,伴随着超皮质地图表达的变化。
