Mg~(++)可活化细胞代谢中的许多酶系,起着转移磷酸基作用,参与生命活动的一切重要过程,目前发现许多疾病与缺镁密切相关。 心血管疾病 镁具有抑制血管运动中枢,阻断神经节传递:扩张血管减轻心脏前后负荷;扩冠;激活细胞膜Na-K-ATP酶,恢复K_+平衡;调节Na-Ca泵和中枢镇静等作用。而心血管疾病多伴缺镁症。故近年多用硫酸镁全身用药治疗这类疾病。 1.高血压危象及脑病。降压作用强弱、快慢与剂量、速度有关。
Mg ~ (++) can activate many enzymes in cell metabolism, play a role in the transfer of phosphate groups involved in all important life processes, and now found that many diseases are closely related to magnesium deficiency. Cardiovascular disease Magnesium can inhibit the vasomotor center and block the transmission of the ganglion: dilate the blood vessel to reduce the anterior and posterior load of the heart; expand the crown; activate the Na-K-ATPase in the cell membrane and restore the balance of K_; regulate the action of Na-Ca pump and central sedation . Cardiovascular disease with magnesium deficiency disease. In recent years, more systemic treatment with magnesium sulfate such diseases. 1. Hypertensive crisis and encephalopathy. Antihypertensive effect strength, speed and dose, speed.
