The influence of selenium supplementation during chelation therapy to reduce body burden and toxicity of lead was investigated in rats. Selenium had marginal effects on liver, kidney and blood lead decorporation by calcium disodium ethylenediamine tetra acetic acid (CaNa2EDTA) and activation of inhibited delta- aminolevulinic acid dehydratase (ALAD) activity by calcium trisodium diethylenetriam...
Insects fed to captive insectivores are deficient in calcium with inverse calcium to phosphorous ratios (Ca:P), and supplementation is required to avoid nutritional metabolic bone disease (NMBD). One method of improving the nutritional value of feeder insects is by “dusting” with powdered supplements, although it is often suggested that these are rapidly shed from prey insects. Here we analysed...
Research on the zinc status of osteoporotic women is scarce. This randomized, double-blind, placebo-controlled clinical trial assessed the effect of zinc supplementation on serum zinc and calcium levels in postmenopausal osteoporotic women. A sample of 60 women referred to a rheumatology clinic in Tabriz were randomly divided into intervention (220 mg zinc sulfate daily) and placebo groups. Ant...
INTRODUCTION Treatment of osteoporosis, in addition to a specific antiresorptive or anabolic treatment, requires supplementation with calcium and vitamin D. Widespread cultivation of pearl shells has made pearls available for commercial use for a very reasonable price. The main chemical compound of pearls from shells Pinctada maxima is calcium-carbonate (CaCO3). Recently developed technologies ...
BACKGROUND Calcium supplementation during pregnancy may reduce the risk of hypertensive disorders of pregnancy. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group trials register and the Cochrane Central Register of Controlled Trials (March 2006). SELECTION CRITERIA Randomised trials comparing at least 1 g of calcium daily during pregnancy with placebo. Eligibility and ...
BACKGROUND Osteoporosis is a serious global health problem for the future, that is why improving diagnostic methods and prevention of this disease could be helpful. OBJECTIVES To assess the effects of calcium supplementations combined with Vitamin D on bone mineral density (BMD) and bone mineral content (BMC) in a representative sample of peri- and post-menopausal women in a double-blind, a r...
The effects of calcium supplementation on blood pressure and its mechanisms were investigated in two-kidney, one clip renovascular hypertensive rats. Two series of experiments were performed: one was begun just after renal artery constriction, the other after the onset of hypertension. Calcium supplementation significantly attenuated the development of hypertension (systolic blood pressure: 183...
BACKGROUND The efficacy of calcium with vitamin D supplementation for preventing hip and other fractures in healthy postmenopausal women remains equivocal. METHODS We recruited 36,282 postmenopausal women, 50 to 79 years of age, who were already enrolled in a Women's Health Initiative (WHI) clinical trial. We randomly assigned participants to receive 1000 mg of elemental [corrected] calcium a...
The role of calcium and vitamin D supplementation in the treatment of osteoporosis has been extensively studied. The aim of this paper was to reach, where possible, consensus views on five key questions relating to calcium and vitamin D supplementation in the management of osteoporosis. Whereas global strategies that target supplementation to the general population could not be justified in ter...
