To establish the best measure for determining magnesium overload, we measured ionized and total magnesium in serum and mononuclear blood cells and total magnesium in erythrocytes in blood of 23 hemodialysis patients, known for their disturbed magnesium homeostasis. When comparing the mean magnesium values obtained in the patient population with those of a control population, all of these magnes...
The magnesium handling of freshwater teleost fish is discussed, with an emphasis on the role of branchial, intestinal and renal transport. In response to the eminent threat of constant diffusive losses of minerals such as magnesium, freshwater fish have developed efficient mechanisms for magnesium homeostasis. Magnesium losses are overcome by the uptake of magnesium from the food, making the in...
BACKGROUND: The Magpie Trial compared magnesium sulphate with placebo for women with pre-eclampsia. 10,141 women were recruited, 8804 before delivery. Overall, 9024 children were included in the analysis of outcome at discharge from hospital. Magnesium sulphate more than halved the risk of eclampsia, and probably reduced the risk of maternal death. There did not appear to be any substantive har...
background: this study was designed to investigate the effect of intravenous magnesium sulfate on hemodynamic changes induced by pneumoperitoneum in patients undergoing laparoscopic cholecystectomy. methods: a randomized, placebo controlled study was performed on 52 asa class i or ii aged 20-70 years patients undergoing laparoscopic cholecystectomy with pneumoperitoneum with carbon dioxide. bef...
Recollection of micropuncture experiments were performed on acutely thyroparathyroidectomized rats rendered magnesium deficient by dietary deprivation. Urinary magnesium excretion fell from a control of 15 to 3% of the filtered load after magnesium restriction. The loop of Henle, presumably the thick ascending limb, was the major modulator for renal magnesium homeostasis. The transport capacity...
Introduction: Gestational hypertension and preeclampsia are important maternal and fetal– infant complications and they can be regarded as the second cause of maternal death as well. The present study aimed to assess the effects of hydralazine and furosemide on blood pressure in sever preeclampsia. Methods: One hundred patients with severe preeclampsia were enrolled. After spontaneous onset o...
Ionised and total magnesium concentrations were determined in the serum of different groups of patients suffering from renal or hepatic diseases. Ionised magnesium was measured by Microlyte 6 (KONE, Espoo, Finland) and total magnesium by atomic absorption spectrometry. In renal insufficiency ionised and total magnesium concentrations were almost equally increased. In proteinuria with a normal g...
background : we assessed the effects of cisplatin-based chemotherapy, magnesium supplementation, probable contributory factors such as cisplatin cumulative dose and dose per cycle on serum magnesium levels. methods : in this prospective randomized study, serum magnesium levels of 59 newly diagnosed adult patients receiving cisplatin-based chemotherapy were studied. the patients were randomly al...
Bone magnesium pools were studied in vitro in bone specimens obtained from control subjects, from patients with chronic renal failure before and after renal transplantation, and in a patient with chronic hypomagnesemia. 30% of bone magnesium is in a surface limited pool present either within the hydration shell or else on the crystal surface. The larger fraction of bone magnesium was shown not ...
Magnesium is required for many of the major organs to function and plays a crucial role in human and mammalian physiology. Magnesium is essential for the structure of bones and teeth, acts as a cofactor for more than 300 enzymes in the body, including binding to ATP for kinase reactions, and affects permeability of excitable membranes and neuromuscular transmission. Despite these essential role...
