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...

Major depression is a mood disorder characterized by a sense of inadequacy, despondency, decreased activity, pessimism, anhedonia and sadness where these symptoms severely disrupt and adversely affect the person's life, sometimes to such an extent that suicide is attempted or results. Antidepressant drugs are not always effective and some have been accused of causing an increased number of suic...

Outer hair cell (OHC) metabolism is blocked by cisplatin. Concurrent changes in the renal handling of magnesium occur because of the damage cisplatin causes to the renal proximal tubule cells within the thick ascending loop of Henle. Although there is no evidence of cisplatin within the OHCs, there are significant levels of intracellular calcium, the antagonist to magnesium at the cell membrane...

BACKGROUND Evidence suggests the involvement of calcium and magnesium metabolism in the pathophysiology of preeclampsia. However, findings from studies are heterogenous and inconsistent. AIM The study aimed to compare the total serum calcium and magnesium levels in preeclamptic women with that of normotensive pregnant women. SUBJECTS AND METHODS A cross-sectional subjects of eighty pregnant...

For 4 weeks, 3-month old germfree (GF) and conventional (CV) rats were given a semi-synthetic diet sterilized by irradiation with or without 10% of lactose. During the 5th week, 0.2% of titanium oxide (TiO2) was added to the diet and the rats were killed at regular intervals throughout the light/dark cycle. The patterns of TiO2 and 45Ca excretion were similar, indicating that TiO2 was a good ma...

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...

Dairy intake has been inversely associated with insulin resistance, which may be partly due to the specific effects of calcium and magnesium. Data from the Insulin Resistance Atherosclerosis Study (1992-1999) for 1,036 US adults without diabetes at baseline were examined to evaluate the cross-sectional association of habitual dairy, magnesium, and calcium intake with insulin sensitivity at base...

In this study, the feasibility of using magnetic technology to reduce the dispersion of soil has been investigated. The reference treatment was potable water and 3 magnetic water devices (with different magnetic intensities) were used for magnetizing the potable water. The results showed that the magnetic field has a significant effect in order of 5 percent on increasing of magnesium concentrat...

of hyperparathyroidism. This study examines the regulation of parathyroid gland activity in magnesium-deficient rats. Magnesium deficiency was induced in intact and chronically parathyroidectomized animals by feeding them a diet free of this cation. Control animals were pair fed and treated identically except for the inclusion of magnesium in their gavage solution. Magnesium-deficient rats with...
