PTH has a reciprocal effect on phosphate metabolism. In contrast, vitamin D has a stimulatory effect on both calcium and phosphate homeostasis, playing a key role in providing adequate mineral for normal bone formation. Both hormones act in concert with the more recently discovered FGF23 and ...
Phosphate depletion in the rat: Effect of bisphosphonates and the calcemic response to PTH. Background. The removal of phosphate from the diet of the growing rat rapidly produces hypercalcemia, hypophosphatemia, hypercalciuria, and hypophosphaturia. Increased calcium efflux from bone has been shown to...
The purpose of this study was to investigate the effect of hypoxia on phosphate excretion after surgical stress in conscious rats. Wistar rats weighing 200 g were exposed to hypoxia (0.10 FiO2) or normoxia (0.21 FiO2) for 24 h following a 20 h equilibrium time after catheterization operation....
It has been well established that soluble mediators of immune cell function including chemokines, cytokines, and several growth factors are required for the regulation of osteoblast and osteoclast activity and are also necessary for the PTH-mediated effect on bone. Monocyte chemoattractant protein-1 (M...

Effects of a parathyroidectomy on the immune system and nutritional condition in chronic dialysis patients with secondary hyperparathyroidism Parathyroid hormone (PTH) has an adverse effect on the immune system and may cause immunologic disorders in patients ...
Parathyroid hormone (PTH) and glucagon increase the urinary fractional excretion of phosphate, but insulin administration is associated with a decreased fractional excretion of phosphate. It was the purpose of this study to determine whether insulin will antagonize the effects of PTH and glucagon on cA...

目的 研究老年妇女甲状旁腺激素的分泌变化以及维生素 1,2 5 (OH) 2 D3的疗效. 方法 测定 2 0例年轻妇女 (2 5～ 3 5岁 )和 2 0例老年妇女 (70～ 78岁 )血清PTH浓度 ,用RIA方法测定使用 1,2 5 (OH) 2 D3前后PTH的变化.使用RIA方法测定血清 1,2 5 (OH ) 2 D和 2 5 (OH)D的血清浓度....
The purpose of this study was to establish a reliable model of metaphyseal bone healing and to use this model to investigate the effect of recombinant human osteogenic protein 1 (rhOP-1; BMP-7) and parathyroid hormone fragment (PTH 1–34) on healing. A wedge-shaped osteotomy was created in...
