据 B M Altura 等报告,由于急性 Mg 缺乏引起的血管收缩及血管活性物质诱发的脑血管收缩,用硫酸镁后可以使之缓解。这与Mg 和 Ca 拮抗作用有关,而 Ca 拮抗剂又能改善脑循环。本文通过 Mg 负荷试验研究了Mg 对局部脑循环的影响。研究对象为平均年龄67.2岁的脑卒中稳定期患者36名。其中脑梗塞29名,脑出血7名。发病均在3周以上,意识比较清楚且没有呼吸及循环系统疾病。对照组平均年龄为 According to reports by B M Altura et al, magnesium sulfate can relieve vasoconstriction induced by acute Mg deficiency and vasoconstriction induced by vasoactive substances. This is related to the antagonism of Mg and Ca, which in turn improves the cerebral circulation. In this paper, Mg load test study of the impact of Mg on the local cerebral circulation. The subjects were 36 stable stroke patients with a mean age of 67.2 years. Including 29 cerebral infarction, cerebral hemorrhage 7. The incidence of more than 3 weeks, more aware of consciousness and no respiratory and circulatory diseases. The average age of the control group was
