Ceylon Medical Journal Magnesium sulphate is increasingly being used in clinical practice, especially in the management of eclampsia, tetanus and severe bronchial asthma. Magnesium is known to influence the body’s calcium homeostasis. Hypomagnesaemia leads to hypocalcaemia by inducing resistance to parathormone (PTH) in bone and kidneys and by decreasing PTH release. Interestingly, hypermagnesa...

1. Magnesium metabolism has been studied in forty-eight patients with primary hyperparathyroidism. Metabolic balance studies were undertaken in forty-three untreated patients and in fifteen patients after parathyroidectomy. The data obtained are compared with the pattern of magnesium metabolism in healthy adults, as established by analysis of collected nutritional studies. The renal handling of...

OBJECTIVE To review the components of calcium, phosphate and magnesium metabolism that are relevant to the critically ill patient in a two-part presentation. DATA SOURCES A review of articles reported on calcium, phosphate and magnesium disorders in the critically ill patient. SUMMARY OF REVIEW Calcium, phosphate and magnesium have important intracellular and extracellular functions with th...

BACKGROUND The influence of extracellular calcium on phagocytosis is limited, and the involvement of extracellular magnesium is unclear. AIMS The role of extracellular calcium and magnesium on phagocytosis efficiency was investigated. RESULTS Extracellular calcium had no influence on the internalization of 1 μm polystyrene particles by primary monocytes as has been shown before for the huma...

The activation of defense genes in response to wounding involves the integration of multiple inputs from various signaling molecules produced in different tissues and cellular compartments. In this report, we demonstrate that calcium and magnesium ions enhance systemin activity and that calcium fluxes are necessary for wound gene activation. During wounding, intracellular contents such as calci...

Cooperative effects of magnesium ions and acidic polypeptides originating from a family of proteins known as Asprich (mollusk Atrina rigida) were studied. In our previous studies, these two acidic polypeptides were found to be effective in controlling the morphology of the calcium carbonate mineral, the main inorganic constituent of prismatic layer of the mollusk shell. Since these Asprich sequ...

Different Aluminum: alkaline earth metal atomic weight ratios effects on structure transformations in alanates nanopowders were studied. Changes in crystal structures from alane to alanates by increasing alkaline earth metals dopants in the mixture with slight changes in crystal structures from rhombohedral centered – trigonal (alane) to trigonal (magnesium alanate), and monoclinic (calcium ala...

In order to investigate the effect of growth media and nutrition method on the growth of Bellis perennis L. and nutrients uptake, a factorial experiment was conducted with two factors: growth media (municipal waste compost, Azolla compost, tea wastes compost) and nutrition method (without fertilizer, soil application, foliar spray) in comparison to the control medium (60% soil + 20% manure + 10...

BACKGROUND AND PURPOSE We aimed to investigate the associations of dietary and total potassium, magnesium, and calcium intakes with stroke occurrence. METHODS A prospective cohort study was conducted among 36 094 participants aged 21 to 70 years. Dietary intake was assessed with a food frequency questionnaire. RESULTS During 12 years of follow-up, 631 strokes occurred. After adjustment for ...

The concentration levels of salivary calcium, magnesium and zinc can vary in different localized oral, as well as systemic diseases and conditions. So far changes in the concentration levels of specific electrolytes in stimulated parotid saliva in HIV-positive/AIDS patients have been proven. The objective of this research was not only to study the concentration levels of calcium in non-stimulat...
