Recent evidence supports the concept that cerebral vasospasm is involved in the pathogenesis of eclampsia. Magnesium, which has a beneficial effect in eclampsia, may act by opposing calcium-dependent arterial constriction, thereby relieving vasospasm. Magnesium may also antagonize the increase in intracellular calcium concentration caused by ischemia and thus prevent cell damage and death. Magn...

To get complete information about the chemical composition and physicochemical principles underlying the formation of stone there is a need for more precise information. At present there is no single analytical procedure that provides an exact quantitative analysis of urinary calculi. In this present procedure it is assumed that only calcium oxalate monohydrate, hydroxyapatite, or magnesium amm...

Moderate levels of calcium or magnesium were applied to two cultivars subirrigated, potted, pinched chrysanthemums during vegetative growth. Market-quality plants produced with sufficient leaf-calcium leaf-magnesium even though the delivery respective nutrient could be reduced by approximately 87.5%, compared industry standards. This practice contribute low-input production floricultural crops.

A particular deadly combination occurs in young athletes, which includes low magnesium intake, high calcium intake, low intake of omega‐3 fatty acids and excitotoxin food additives. Strenuous exercise—especially in extreme heat is known to deplete the body’s magnesium stores, as is consumption of carbonated drinks and taking calcium supplements. In addition, adrenalin secretion, increased durin...

Levels of phenoloxidase (Po), trypsin and lysozyme activities were determined following 48 hours exposing freshwater crayfish (Pontastacus leptodactylus) weighing 59.8&plusmn;3.4g to different low pH values of 6.5, 5.5, 4 and 2.5 at 20-23˚C. Significant decrease were found (p<0.01) in levels of Po and trypsin activities in crayfish haemocyte lysate supernatant (HLS) at pHs 5.5 and 4 compared to...

The prelytic adhesion of immune cytolytic thymus-derived lymphocytes to specific antigen-bearing ascites tumor target cells has been studied. A new assay was used in which adhesions are permitted to form for 2.5 min; the cells are then dispersed to prevent further adhesion, and the predispersion adhesions are quantitated by subsequent 51Cr release from the tumor cells as a result of cytolytic a...

Hypocalcemia and resistance to exogenous parathyroid hormone have been reported in several clinical states associated with magnesium deficiency. On the basis of such observations, it has been suggested that magnesium depletion per se may result in impaired responsiveness of the adenyl cyclase-adenosine 3',5'-monophosphate (3',5'-AMP) system. To test this hypothesis, 4 wk old male parathyroidect...

Developmental programming of hypertension, induced by maternal protein restriction, is associated with enhanced urinary excretion of sodium and calcium in the rat. Although calcium and magnesium are reabsorbed via different pathways, renal calcium excretion often parallels magnesium output. Accordingly, the aim of the current study was to assess magnesium handling in rats exposed to a low-prote...
