Mg~(++)称为天然的Ca~(++)拮抗剂,有扩张血管作用。从这一点出发,对能否在改善脑循环上有效果进行了研究。对象是发作2～3周,意识比较清楚,脑卒中稳定期患者42人。用蒸馏水溶解的Mg~(++)(MgSO_4)2g、50分钟内静脉点滴,测定前后局部脑血流量(r—CBF)。结果,脑卒中患者r—CBF 增加20%以上,认为Mg~(++)可以改善脑循环,而且这个增加率要比青年健康者(同样进行试验)更有意义。为明确对负荷反应差别的原因,岩崎等词查了脑卒中与健康者血清Mg~(++)值与Mg~(++)排泄量。结果是血清Mg~(++)值,尿中Mg~(++)排泄值在两组间虽几乎没有差
Mg ~ (++) Called the natural Ca ~ (++) antagonist, dilate blood vessels. From this point of view, whether or not there is an effect on improving cerebral circulation has been studied. The object is episodes of 2 to 3 weeks, more aware of consciousness, stable stroke in 42 patients. Using distilled water dissolved Mg ~ (++) (MgSO4) 2g, intravenous drip within 50 minutes, measured before and after the regional cerebral blood flow (r-CBF). As a result, r-CBF increased by more than 20% in patients with stroke, suggesting that Mg ~ (++) improves cerebral circulation and that this rate of increase is more meaningful than that of healthy young adults (also tested). In order to clarify the reason of the difference in response to load, Iwasaki and other words to check serum Mg ~ (++) value and Mg ~ (++) excretion of stroke and healthy people. The result was a serum Mg ~ (++) value, with almost no difference in urinary Mg ~ (++) excretion between the two groups
