Background: Magnesium ion is critical for life and is integrally involved in cellular function and a key component of normal bone mineral. In health, the kidneys, gastrointestinal tract and bone are responsible for maintaining serum magnesium concentrations in the normal range and magnesium balance. Most clinical disorders involving magnesium, other than chronic kidney disease (CKD), result in ...

to evaluate the effect of intravenous infusion of a soybean based lipid emulsion (lipovenoes 10%) on some blood constituents in sheep, a replicated 2 × 2 latin square design experiment was conducted in four clinically healthy ewes. lipid emulsion (le group) or normal saline (ns group) was infused intravenously at a rate of 0.025 ml kg-1 per min for 6 hr and the concentrations of blood triglycer...

The membrane potential in the dark and the saturated response height of the ventral nerve photoreceptor of Limulus was measured by an intracellular electrode while the external concentra­ tion of calcium, magnesium and sodium ions was varied. Decreasing the extracellular calcium concentration from 10-2 mol/1 causes a calcium-dependent lowering of the dark membrane potential and at very low conc...

Background: Pre-eclampsia along with its complications seems to be one of the major causes of maternal morbidity and mortality. Despite numerous studies, the etiology of pre-eclampsia has not yet been fully elucidated. According to recent studies changes in the level of blood trace elements can be an adverse event in human and animal pregnancy. The present study determines whether maternal seru...

BACKGROUND It has been reported that adequate calcium intake decreases body fat and appropriate intakes of magnesium suppress the development of the metabolic syndrome. Furthermore, lactulose increases the absorption of calcium and magnesium. An optimal combination of calcium, magnesium and lactulose may therefore reduce body fat mass. METHODS An open-label randomized controlled trial was con...

This study determined the effect of long-term administration of 4(G)-beta-D-galactosylsucrose (lactosucrose; LS) on intestinal calcium absorption. In a randomized, single-blind, parallel-group study, LS (n=9, 6.0 g twice daily) or a placebo (maltose; n=8, 6.0 g twice daily) was administered to healthy young women for 92 wk: the study also included a 4-wk post-administration period. All particip...

Introduction: In spite of many studies about the association of diet with blood pressure, yet the relationship between micronutrients and blood pressure remains obscure. This study aimed at evaluating the dietary intake of calcium, magnesium and potassium in relation to blood pressure. Materials and Methods: Trained interviewers collected dietary data on 1470 participants of Tehran Lipid and Gl...

INTRODUCTION Recent epidemiological evidence suggests that alteration in calcium, phosphorous or magnesium metabolism may have direct cardiovascular consequences. However, it is unknown whether variations in serum values of these minerals are in relationship with lipid profile and adiposity as metabolic risk factors of cardiovascular events in premenopausal women independent of confounders. The...

Calcium and magnesium contents of whole erythrocytes and of erythrocyte membranes (stroma) were determined by atomic absorption technique on five mammalian species, man, rabbit, pig, cow and dog. In every species, the magnesium content of the whole erythrocyte is predominantly higher than the calcium content. Of the total magnesium, about 2-6% are localized in the membrane, whereas 40-86% of th...

Ageing in industrialised societies is associated with an increasing prevalence of hypertension, atherosclerotic vascular diseases, reduced insulin sensitivity and non-insulin-dependent diabetes mellitus (NIDDM). It has been suggested that hyperinsulinaemia/insulin resistance and/or hyperglycaemia could play a role in determining and/or exacerbating the hypertension and vascular disease associat...
