迟发性神经元坏死(DND)的研究表明,其发生机制与离子的改变有关,特别是钙超载是DND发生的重要原因。本文应用离子光谱仪对DND时的海马和颞顶叶皮质进行了不同时相的多项离子测定。结果发现,就整体而言,DND时海马和颞顶叶皮质中钙含量不是增高而呈下降的趋势。这说明钙超载是在微观的环境中变化,即细胞内外钙分布发生了变化,由细胞外进入了细胞内,其总量并无增多。 Delayed neuronal death (DND) studies have shown that the mechanism of its occurrence and ion changes, especially calcium overload is an important cause of DND. In this paper, Ions ion spectrometry DND when the hippocampus and temporo parietal cortex were measured at different phases of a number of ions. The results showed that, on the whole, the calcium content of hippocampus and temporal parietal cortex in DND was not increased but decreased. This shows that calcium overload changes in the micro-environment, that is, intracellular and extracellular calcium distribution has changed from outside the cell into the cells, the total did not increase.
