This study assessed the effect of calcium supplementation towards the change in serum calcium, phosphorus and magnesium level. We carried out a randomized controlled trial of calcium supplementation in 113 postmenopausal women for 24 months period study. Subjects were randomly assigned into two groups. Subjects in Calcium Supplemented Group (CSG) were to take calcium supplement (1200 mg/day) wh...

A preterm infant with hypophosphataemic rickets became hypocalcaemic when given milk specially formulated for preterm infants that contained increased phosphorus and calcium. The rickets resolved spontaneously. Routine calcium and phosphorus supplementation for preterm neonates should be investigated further.

Since the calcium-protein relationship for a purified protein is adequately described by the law of mass action (l), it follows that the inconsistencies between the total calcium and total protein for sera (2) probably represent the cumulative effect of a number of variables. The present report deals with some of these variables as follows: the effect of excessive amounts of CaClz on the calciu...

Purpose. Secondary hyperparathyroidism with nodular hyperplasia is resistant to medical therapies. Cinacalcet is an effective treatment for severe secondary hyperparathyroidism. This multicentre retrospective study was designed to determine the long-term efficacy of cinacalcet in patients with nodular hyperplasia, the advanced type of parathyroid hyperplasia. Subjects and methods. The study sub...

In mammals, phosphocalcic and bone metabolisms are mainly regulated by parathyroid hormone, parathyroid hormone-related peptide (PTHrP) and 1α,25-dihydroxyvitamin D or calcitriol. In camels, circulating levels of calcitriol are 10 times higher than those determined in other ruminants and further increase during early lactation. Calcitriol and parathyroid-related peptide stimulate intestinal abs...

No significant differences were found in the reactions of irradiated, normal, or partially parathyroidectomized rabbits to injections of calcium chloride or disodium hydrogen phosphate. Intravenous injections of calcium chloride caused only a transient rise in blood calcium, which returned to its former level within a few hours. The upper level of blood calcium concentration is independent of p...

Calcium and phosphorus exist in a delicate balance in the body, with bone playing a central role in maintaining whole-body calcium–phosphorus homeostasis. The balance of phosphorus and calcium in healthy individuals is maintained through the complex interplay between parathyroid hormone (PTH) and 1,25-dihydroxyvitamin D3 (calcitriol). If serum calcium levels fall, PTH acts to increase renal rea...

It has been shown repeatedly (14) that in cardiac and renal disease, both in adults and children, there is a direct relationship between the levels of serum protein and serum calcium, and also, within limits, an inverse relationship between the serum inorganic phosphorus and the serum calcium (l-5). Peters and Eiserson (4) attempted a mathematical evaluation of the relative effects of protein a...
