前言降钙素(简称CT)是Hirsch等1963年首先从大白鼠的甲状腺中发现的,二十年来对它的化学结构、生理功能及临床应用都进行了大量的研究工作,特别是近些年来把它应用到晚期癌骨转移的治疗方面,取得了令人满意的效果。当然还有不少问题有待于进一步的探讨,但可以说, Introduction Calcitonin (abbreviated as CT) was discovered by Hirsch et al. from the thyroid gland of rats in 1963. In the past 20 years, a lot of research has been done on its chemical structure, physiological function and clinical application, especially in recent years. It has been applied to the treatment of advanced cancer bone metastases and has achieved satisfactory results. Of course, there are still many issues that need further discussion, but it can be said that
