Ｃａ２＋和Ｍｇ２＋是一对相关的阳离子，它们在脑缺血的病理生理变化中起着重要作用。本试验通过对兔脑缺血后脑细胞线粒体Ｃａ２＋、Ｍｇ２＋的测定，发现缺血早期线粒体Ｃａ２＋明显增高而Ｍｇ２＋明显下降，结果提示Ｍｇ２＋／Ｃａ２＋比值下降在缺血性脑损害中具有重要意义。
Ca2 + and Mg2 + are a pair of related cations, which play an important role in the pathophysiological changes of cerebral ischemia. In this study, we measured the content of Ca2 + and Mg2 + in mitochondria after cerebral ischemia in rabbits and found that the content of Ca2 + in mitochondria increased obviously and the content of Mg2 + decreased obviously in early ischemia. The results suggest that the decrease of Mg2 + / Ca2 + ratio is of great significance in ischemic brain damage.
