A simple and rapid procedure has been developed for the complexometric titration of serum calcium and magnesium using "plasmocorinth B" as indicator. Both determinations can be carried out from the same 0.5 ml. sample. The method is in good agreement with the established calcium and magnesium methods.

The effect of magnesium chloride or magnesium sulfate infusion on circulating levels of immunoreactive calcitonin (iCT) was evaluated on nine occasions in three patients with metastatic medullary carcinoma of the thyroid. One patient was normocalcemic and had normal circulating levels of immunoreactive parathyroid hormone (iPTH), one patient was hypocalcemic and had surgical hypoparathyroidism,...

ATOMIC ABSORPTION was developed by Walsh and his associates (1) as an analytical technic applicable to the determination of many metals. Willis (2-4) found that this technic was applicable in particular to tile determination of calcium and magnesium in Serum and urine. These published results indicated that atomic absorption spectrophotometry would be a simple, rapid, and practical method for t...

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 preeclampsia 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 serum...

OBJECTIVES Complications such as ascites during the pathogenesis of hepatic fibrosis and cirrhosis may lead to several abnormalities in mineral metabolism. In the present investigation, we have monitored serum and liver concentrations of calcium, magnesium, sodium and potassium during experimentally induced hepatic fibrosis in rats. DESIGN AND METHODS The liver injury was induced by intraperi...

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 ...

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...

Introduction: Calcium critical limit in pistachio plants is about 1.3 percent of plant dried material; magnesium critical limit in pistachio leaves is about 0.6 percent of plant dried material. To measure calcium and magnesium there are several methods in which three methods of titration and atomic absorption that are more common and used to libraries more in addition to ICP modern method are u...

The flow system developed for the determination of serum calcium by automated atomic absorption spectrophotometry (AAS) was adapted to the determination of serum magnesium. A comparison of the results of analyses by the present procedure and by an automated fluorometric procedure on identical serum specimens shows excellent agreement. from this laboratory described tile application of automated...

To assess whether magnesium treatment in patients with subarachnoid haemorrhage (SAH) is associated with hypocalcaemia and whether hypocalcaemia in these patients is associated with an increased risk of delayed cerebral ischemia (DCI) and poor outcome. All 137 patients randomized in the clinically controlled "Magnesium in Aneurysmal Subarachnoid Haemorrhage" trial were included. The relationshi...
