The effects of pressure on the crystal structure of the three known polymorphs of magnesium sulfate (α-MgSO4, β-MgSO4, and γ-MgSO4) have been theoretically studied by means of density-functional theory calculations up to 45 GPa. We determined that under ambient conditions γ-MgSO4 is an unstable polymorph, which decomposes into MgO + SO3, and that the response of the other two polymorphs to hydr...

Objective- To compare the lidocaine-MgSO4 combination with lidocaine-Distilled water inthe epidural of indigenous awake dogs.Design- Prospective experimental study.Animals- Five young (12±2 months) female indigenous dogs weighting (10.74 ± 0.44 kg).Procedures- Epidural anesthesia was produced in all dogs with 2% lidocaine (1ml/4.5 kgbody weight) with 1 ml distilled water and two weeks later rep...

OBJECTIVES The use of magnesium sulfate (MgSO4) in European obstetric units is unknown. We aimed to describe reported policies and actual use of MgSO4 in women delivering before 32 weeks of gestation by indication. METHODS We used data from the European Perinatal Intensive Care in Europe (EPICE) population-based cohort study of births before 32 weeks of gestation in 19 regions in 11 European ...

Aim The aim of the present study was to assess the protective effects of magnesium sulfate (MgSO4) on ischemia/reperfusion (I/R) induced ovarian damage in a rat ovarian torsion model. Methods Forty-two female Sprague Dawley rats were included in the study. They were divided into six groups as Group 1, sham; Group 2, bilateral ovarian torsion; Group 3, bilateral ovarian torsion-detorsion; Grou...

introduction: considering the high incidence of preterm labor and its known complications, and that human myometrium contains receptors for human chronic gonadotropin (hcg) and that hcg can inhibit myometrial contractions on vitro, made me study treating effects of hcg on preterm labor. this clinical trial study was carried out to compare the effect of hcg, and magnesium sulfate (mgso4) on prev...

The scarcity of durable and low-cost sorbent materials remains a significant technological barrier to long-term heat storage. In the present work, composite based on activated carbon supports magnesium sulfate hydrates (labelled MgSO4/AC) were developed in order increase energy density improve mass transport phenomena. results characterization revealed uniform dispersion composites produced via...

AIMS To investigate the effects of parenteral administration of MgSO4, and glucose, insulin, and potassium (GIK), on the dominant atrial cycle length during chronic atrial fibrillation (CAF). METHODS AND RESULTS The length of the dominant atrial cycle (DACL) in the power-frequency spectrum of the QRST-suppressed lead V1 ECG was identified before and after intravenous administration of MgSO4 a...

The incidence of Postpartum Hemorrhage (PPH) is increasing in the western world. We hypothesize that magnesium sulfate (MgSO4) could be a contributing factor. MgSO4 might increase the incidence of PPH by induction of vasodilation, tocolytic effects, and effects on the blood like red cell deformity, platelet activity inhibition and a prolonged bleeding time. Based on these effects of MgSO4 a cor...

The multiplication of mouse hepatitis virus (MHV) was inhibited by the treatment of infected cells with MgSO4 at concentrations higher than 50 mM. The inhibition of viral multiplication was more effective with the treatment of cells at the early stage of infection using MgSO4 than at the late stage. Viral adsorption to the cells was not inhibited by MgSO4 and pretreatment of the cells with MgSO...

Background: Lactate Dehydrogenase (LDH) is most often measured to evaluate tissue damage. Magnesium sulfate is used for seizure therapy and as prophylaxis for eclampsia and preeclampsia, worldwide. The objectives were: 1. To assess serum LDH levels as a biochemical marker to reflect the severity of pre-eclampsia/eclampsia 2. To study the alterations in serum magnesium levels in eclampsia patien...
