钙是骨骼的主要构成部分,骨组织的正常生长和发育需要适当的钙营养。调节钙平衡的激素有维生素D、甲状旁腺素(PTH)、降钙素(CT)及雌激素,肝、肾及肠道功能对钙代谢也起重要作用。分析钙代谢异常及有关机制,有助于相关疾病的诊断及治疗,其临床意义十分重大。现介绍如下。1低血钙 Calcium is a major component of bone and the proper growth and development of bone tissue requires proper calcium nutrition. Calcium balance of hormones with vitamin D, parathyroid hormone (PTH), calcitonin (CT) and estrogen, liver, kidney and intestinal function also plays an important role in calcium metabolism. Analysis of abnormal calcium metabolism and related mechanisms, contribute to the diagnosis and treatment of related diseases, its clinical significance is very significant. Now introduced as follows. 1 hypocalcemia
