Altered diurnal regulation of blood ionized calcium and serum parathyroid hormone concentrations during parenteral nutrition.
BACKGROUND Little is known about parathyroid gland function in patients receiving total parenteral nutrition (TPN). OBJECTIVE Our objective was to determine whether parathyroid gland function is abnormal in TPN recipients. DESIGN Six patients with a mean (+/-1 SD) age of 45.5 +/- 8.0 y who had been receiving TPN for 18.7 +/- 2. 8 y underwent bone biopsy, bone mass measurements with dual-ene...
متن کاملAssessment of calcium balance in patients on hemodialysis, based on ionized calcium and parathyroid hormone responses.
BACKGROUND Identification of the underlying causes of secondary hyperparathyroidism (SHPT) in individual patients on hemodialysis (HD) is hampered by the lack of clinically reliable information on calcium balance. The aim of this study was to assess calcium balance during HD sessions with a method that is applicable in day-to-day practice. METHODS Plasma ionized calcium (pCa2+) and parathyroi...
متن کاملSerum profiles of calcium, phosphorus, magnesium, vitamin D and parathyroid hormone in Caspian horses during different seasons
Minerals play an essential role in the normal vital process.Calcium, phosphorus and magnesium are the most abundant minerals. Vitamin D and parathyroid hormone play a key role in regulation of their homeostasis as well. The aim of this study was to evaluate calcium, phosphorus, magnesium, vitamin D and parathyroid hormone on 30 Caspian horses of Guilan Province (south of the Caspian Sea) in two...
متن کاملThe acute effect of chlorothiazide on serum-ionized calcium. Evidence for a parathyroid hormone-dependent mechanism.
The acute effects of chlorothiazide (CTZ) on total (TSCA) and ionized (SCA-plus 2) serum calcium concentrations were studied in three groups of people: (a) eight subjects with normal parathyroid function; (b) six patients with hypoparathyroidism; and (c) two patients with hyperparathyroidism. Most subjects were studied on four occasions; at least 3 days intervened between studies on an individu...
متن کاملAn analysis of the role of serum in parathyroid hormone-induced bone resorption in tissue culture.
THE stimulation of bone resorption by parathyroid hormone can be quantitated in tissue cultures of embryonic bone [20], using paired limb bones from a single embryo in which radioactive calcium (45Ca) has previously been incorporated. The ratio of 45Ca release from the parathyroid hormonetreated bones to that from the control bones is a sensitive measure of parathyroid effect. This technique ha...
