钙是构成机体的必须元素之一,约占体重的1.5%~2.0%,90%以上的钙以骨盐形式存在于骨骼和牙齿中,同时也参与神经传递、肌肉运动、内分泌等[1]。新生儿娩出后,机体需要的钙主要靠母乳获得,钙水平进入低水平,为了满足骨骼、大脑的生长只能通过血中的血钙素和降钙素调节。摄入过量的氟,一方面会直接影响机体内分泌变化,另一方面间接性通过影响钙的代谢而造成相应的调节激素水平的变
Calcium is one of the essential elements that make up the body, accounting for 1.5% -2.0% of body weight. More than 90% of calcium is present in bones and teeth as bone salts and is also involved in nerve transmission, muscle movement, endocrine, etc. [1] . After the delivery of the newborn, the body needs calcium mainly by breast milk, calcium levels into the low level, in order to meet the bones, the growth of the brain can only be adjusted by the blood of calcitonin and calcitonin. Excessive intake of fluorine, on the one hand will directly affect the body’s endocrine changes, on the other hand indirectly through the impact of calcium metabolism caused by the corresponding regulation of hormone levels change
