Bone remodelling as a whole is highly dependent on serum calcium levels, which, in turn, are kept in the normal range by a balance between parathyroid hormone, or PTH, calcitonin and vitamin D.

整个骨重建进程高度依清中钙的含量，而将清中钙的含量维持在正常值范围内是由甲状旁腺激素、降钙素与维生素D间的制约平衡所控制的。

On the other hand, calcitonin is produced by the thyroid gland in response to high serum calcium, so it opposes the action of PTH - therefore promoting bone formation and decreasing bone resorption.

一方面，当清中钙含量较高时，甲状腺释放降钙素，来制约甲状旁腺激素的作用，从而促进骨骼的形成并减缓骨骼的吸收。

Because amylin and calcitonin, I think, are gonna be more and more popular, or important, really, clinically, in the future.

因样蛋白和降钙素在未来临床上可能会越来越受欢迎，或者说是越来越重要。

And amylin also, so anything that kind of binds an agonist of amylin also binds calcitonin, which helps with your bones.

还有样蛋白， 任何能结合样蛋白激动剂的东西也会结合降钙素，有助骨骼健康。

Now, you mentioned earlier to me about this, I guess the amylin calcitonin sort of CGRP axis.

现在，你之前跟我提到过这个，我想是关样蛋白、降钙素和降钙素基因相关肽（CGRP）轴的内容。

That's why people will take calcitonin salmon, which is a nasal spray.

这就是什么人们会使用鲑鱼降钙素鼻喷剂。
