Plasma ionized calcium, platelet cytosolic calcium (using the fura-2 method in gel-filtered platelets), parathyroid hormone (both the intact hormone and a midmolecule portion), calcitriol, and calcidiol were measured in 19 untreated male patients with essential hypertension and 19 age-matched normotensive male research subjects. Mean levels of platelet cytosolic calcium, parathyroid hormone, ca...
typed double-spaced (including references) with conventional margins. The overall length is limited to five manuscript pages, including not more than one figure or one table. To the Editor: Ionized calcium is now the measurement of choice for evaluating calcium metabolic diseases (1, 2). Ionized calcium may be reported either as the actual ionized calcium, referred to the actual pH of the patie...
convulsion is one of the most common problems in children and hypocalcemia is one the most frequent etiological items in children’s convulsion. corrected qt (qtc) in ekg is prolonged in hypocalcemia, so it can be a useful tool for evaluation of serum ionized calcium. in three groups (first seizure, multiple seizures, without seizure or control ) every 25 cases, qtc, serum ionized ca, total ca, ...
BACKGROUND Low calcium dialysate with 1.25 mmol/l calcium concentration has been proposed to replace standard calcium dialysate in peritoneal dialysis patients taking calcium-containing phosphate binder to prevent hypercalcaemia. We conducted a meta-analysis to evaluate long term effects on mineral and bone metabolism by low versus standard calcium dialysate in peritoneal dialysis. METHOD Cli...
Calcium plays a pivotal role in excitation-contraction coupling of cardiomyocytes and many other cellular responses observed in cardiovascular cells. Thus maintaining a healthy status requires very strict regulation of cytoplasmatic but also plasma ionized calcium concentration. Plasma ionized calcium is regulated by calcium sensing and the regulation of calcium uptake and secretion. Under cond...
Total and ionized calcium and other related parameters were measured in 34 patients with multiple myeloma. Hypercalcemia was not a major feature of the group of patients studied with only three patients exhibiting marked increases in total (Ca total) and ionized (Ca++) calcium concentrations. The Ca++/Ca total ratio was also maintained within relatively narrow limits. No major differences were ...
Thirteen patients were studied during two hours of anaesthesia for abdmonial operations and for an hour post-operatively. Serial venous blood samples were taken for determination of plasma total and ionized calcium, acid-base variables, Na, K, Mg, PO4 total proteins and parathyroid hormone. One group of patients received 5 per cent dextrose/water and the other 5 per cent dextrose in Ringer's so...
To determine the influence of dietary calcium on spaceflight-induced alterations in calcium metabolism and blood pressure (BP), 9-wk-old spontaneously hypertensive rats, fed either high- (2%) or low-calcium (0.02%) diets, were flown on an 18-day shuttle flight. On landing, flight animals had increased ionized calcium (P < 0.001), elevated parathyroid hormone levels (P < 0.001), reduced calciton...
BACKGROUND Many factors influence serum calcium concentration, but the major determinants of calcium homeostatsis are parathyroid hormone (PTH), vitamin D, the ionized calcium, and phosphate [1]. Therefore, deranged calcium metabolism is often seen in the presence of disordered parathyroid hormone (PTH) and/or vitamin D actions. Among these causes is end-organ resistance to the biological effec...
