目的 :男性与女性相比 ,循环系统疾病发病率男性偏高。已知这些疾病与机体内镁 (Mg)浓度异常有关 ,但是 ,有关性别差异的报道很少。本研究将小鼠实施阉割或子宫结扎后 ,对其进行镁、钾 (K)缺乏食物喂饲实验 ,然后分析血浆、红细胞、肝脏、肾肝、心脏、脑、肌肉以及骨中的元素浓 Purpose: Male and female compared to the incidence of circulatory system disease in men is high. It is known that these diseases are related to the abnormal magnesium (Mg) concentration in the body, however, few reports on gender differences have been reported. In this study, mice were subjected to castration or uterine ligation and then subjected to magnesium and potassium (K) deficient diet feeding experiments, and then analyzed for the concentration of elements in plasma, erythrocytes, liver, kidney, heart, brain, muscle and bone
