甲状旁腺术(PTH)是甲状旁腺主细胞合成和分泌的多肽激素,它通过骨和肾来实现升高血钙,降低血磷的作用:(1)对骨的作用。PTH能动员骨钙入血,使血钙升高。它可作用于骨细胞膜系统,促使Ca2转运入细胞外液,这是PTH动员骨钙入血的快速反应,仅数分钟即刻发生。此外,还可加强破骨细胞的活动,使骨钙大量入血,这一效应为延缓效应,在PTH作用后12~14 h开始,几天或几周后达高峰。两个效应互相配合,不仅能迅速升高血钙,而且能维
Parathyroid surgery (PTH) is a polypeptide hormone synthesized and secreted by the main parathyroid gland cells. It can increase blood calcium and lower serum phosphorus through bone and kidney: (1) The effect on bone. PTH can mobilize bone calcium into the blood, so that elevated calcium. It acts on the membrane of the bone cell membrane and promotes the transport of Ca2 into the extracellular fluid, which is a rapid response of PTH to mobilize bone calcium into the bloodstream, occurring in just a few minutes. In addition, the activity of osteoclasts can also be strengthened, leading to massive calcium infiltration into the blood. This effect is a delaying effect. It begins at 12-14 h after PTH treatment and reaches a peak in days or weeks. Two effects complement each other, not only can quickly increase blood calcium, but also Victoria
