Reduction of Saliva and Serum 25-Hydroxycholecalciferol in Multiple Sclerosis
Methods: The prevalence of multiple sclerosis (MS) is high in patients suffering from 25-hydroxyvitamin D3 [25(OH)D] deficiency. The aim of this study was to investigate the possible association of saliva and serum 25(OH)D concentrations with MS in women.Methods: Serum and saliva 25(OH)D levels of 30 MS women and 30 matched healthy controls in this case-control study were measured by ELIS...
متن کاملMetabolism in vitro of 25-hydroxycholecalciferol in chicks fed on phosphorus-deficient diets.
1. Three groups of 10-days-old chicks were fed on one of three diets having phosphorus contents of 0.08 mol/kg, 0.14 mol/kg or 0.21 mol/kg. Ten days later duodenal calcium absorption by the ligated loop technique in vivo, and plasma calcium and phosphorus concentrations, were measured. In addition the metabolism in vitro of 25-hydroxycholecalciferol [25-(OH)D3] by kidney homogenates was studied...
متن کاملEfficacy of different adsorbents in reducing the toxic effects of aflatoxin B1 in broiler diets
The ability of dietary hydrated sodium calcium aluminosilicate (HSCAS), diatomite and activated charcoal (AC) in reducing the detrimental effects of aflatoxin B1 (AFB1) in broiler diets was evaluated. Adsorbents were supplemented at 2.5 g/kg to the diets containing 0, 40 or 80 μg AFB1/kg feed. One hundred and eighty Ross 308, day-old male broilers were assigned to 12 treatments for 42 days. AFB...
متن کاملEvaluation of Relative Bioavailability of 25-Hydroxycholecalciferol to Cholecalciferol for Broiler Chickens
This study was conducted to evaluate the relative bioavailability (RBV) of 25-hydroxycholecalciferol (25-OH-D3) to cholecalciferol (vitamin D3) in 1- to 21-d-old broiler chickens fed with calcium (Ca)- and phosphorus (P)-deficient diets. On the day of hatch, 450 female Ross 308 broiler chickens were assigned to nine treatments, with five replicates of ten birds each. The basal diet contained 0....
متن کاملMULLITE SYNTHESIS AND FORMATION FROM KYANITE CONCENTRATES IN DIFFERENT CONDITIONS OF HEAT TREATMENT AND PARTICLE SIZE
The process of mullitization of kyanite concentrate was studied at different conditions of heat treatment (1400– 1600 °C and 0.5 – 3.5 hours) and particle size of raw materials (38-300 ?m). Kyanite concentrate was obtained fromore-dressing of kyanite deposits of Mishidowan-Bafgh region at 100 km northeastern part of Yazd. The results ofmicrostructure (shape, distribution and size of the grains)...
