In this study, the salt weathering effects on engineering properties and weight loss potential of three types of granitoid rocks were investigated. Sodium and magnesium sulfates tests were performed on core and aggregate samples. The cyclic salt weathering tests on core samples were done up to 90 cycles, while these tests on aggregate samples were done up to 40 cycles. The results showed that d...

Preliminary evidence has suggested that magnesium sulfate infusion reduces delayed ischemic neurological deficit and improves clinical outcome after aneurysmal subarachnoid hemorrhage. However, little is known about its site of action in vivo. We studied 22 aneurysmal subarachnoid hemorrhage patients with or without magnesium sulfate infusion for 10-14 days. Thirteen patients had external ventr...

background: the aim of this study was to evaluate the effect of two injections doses of magnesium sulfate for controlling and reducing hemodynamic changes caused by laryngoscopy and endotracheal intubation in pregnant women who were candidates for caesarean section with general anesthesia. methods: in this controlled randomized double-blind clinical trial, 165 pregnant women who were candidates...

to study the role of preoperative intravenous magnesium sulphate in decreasing post-cesarean pain and opioid requirement during first 24hrs.in a double blind randomized clinical trial, prior to induction of general anesthesia, fifty elective cesarean candidates were randomly assigned to one of the two groups of placebo or magnesium sulfate. after surgery visual analogue scale (vas) and infused ...

conclusions intravenous etomidate 0.03 mg/kg prior to induction can effectively reduce the incidence and severity of myoclonus linked to etomidate. results the incidence and intensity of myoclonus were significantly lower in the low-dose etomidate group. the incidence rates of myoclonus were 51 (71.85%), 61 (85.9%), 30 (42.3%) and 41 (57.7%), and the percentages of patients who experienced grad...

introduction: migraine is a common cause of emergency department (ed) visits. to date, there is no recommended drug of choice for pain management of these patients. in the present study, we aimed to evaluate the effectiveness of ketorolac and magnesium sulfate in this regard. methods: this is a cross-sectional study performed on all 18 - 60 year-old patients, visiting two different eds with com...

OBJECTIVE Magnesium sulfate has been shown to have a bronchodilating effect in asthma, but this effect has not been clearly established in the context of chronic obstructive pulmonary disease (COPD). For this reason we investigated the possible bronchodilating effect of magnesium sulfate in COPD exacerbations. PATIENTS AND METHODS We studied 24 patients with exacerbated COPD who required admi...

Magnesium sulfate is widely used as a food additive and as an orally administered medication. The aim of this study was to evaluate the possible cytotoxicity of magnesium sulfate on AGS human gastric adenocarcinoma cells and gastric mucosa in mice. A trypan blue exclusion assay was used to determine the reduction in viability of AGS cells exposed to magnesium sulfate, and then effects on cell p...
