ABSTRACT Background: To determine daily calcium, Vitamin D intake and serum biochemical findings of rickets in adolescent girls. Methods: A total of 414 healthy adolescent student girls aged 11-15 years were evaluated from various areas of Tehran, Iran with different socioeconomic status. A randomized, cross-sectional, prospective and descriptive study was undertaken for calculation of daily c...

Several factors have been identified as important in the pathogenesis of secondary hyperparathyroidism in end-stage renal disease, including serum calcium, phosphorus, and calcitriol. To examine the independent effects of key factors, we prospectively studied 52 new hemodialysis patients with mild secondary hyperparathyroidism (PTH, 110-670 pg/mL) treated with a standardized regimen of calcium ...

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...

Mineral profile and some selected components of three cultivars of onion (Allium cepa L.) (Dan Zaria, red creole and white creole) bulb were compared with garlic (Allium sativum L.) clove. This was pertinent to establish their potentials in ensuring adequate nutrition and food security. Simultaneous multi-element analysis was done by inductively coupled plasma-optical emission spectroscopy (ICP...

the main reasons for the fixation of some elements and consequently nutrient deficiencies, especially phosphorus, iron and zinc, are high levels of calcium (calcareous soils) and soil ph. two sulfur fertilizers (sulfur alone and sulfur + organic material + thiobacillus spp.) with two rates (2 and 4 kg sulfur/tree) were used to decrease soil ph and availability of p, fe and zn in apple trees dur...

Both 1,25-dihidroxyvitamin D3 and phytase are known to improve phosphorus utilization in broilers(Biehl and Baker,J Nutr 1997). Solanum glaucophyllum(Sg) is a plant containing high amounts of 1,25dihydroxyvitamin D bound to a glycoside. It may be an economical source of 1,25-dihydroxyvitamin D for animal feeds. We examined the effect of Sg, with and without phytase, on phosphorus utilization in...

An experiment was conducted to evaluate the effects of one alpha-hydroxycholecalciferol (1α-OH D3) on growth performance, tibia quality, and skin and meat color in broilers fed calcium (Ca)- and phosphorus (P)-deficient corn-soybean meal diets. A total of 288 male Ross broilers, at 21 days of age, were randomly assigned to three treatments with eight cages per treatment. Three levels of 1α-OH D...

in this study for determinination of effects of anesthesia with propofol on some of biochemical factors of blood, 120 grass carp were chosen. the fish were exposed to the ascending concentration of propofol by bath method and injection method. at the time of anesthesia and 4 days after anesthesia blood samples were taken from the caudal vein and some biochemical parameters of blood were measure...
