the purpose of this study was to examine the effect of intravenous magnesium sulfate on patients with copd exacerbation requiring hospitalization. in this randomized clinical trial 30 patients with copd exacerbation were studied. patients were randomly assigned to group a (case) who concurrent with standard therapy received 2g magnesium sulfate in normal saline infused in 20 minutes on days one...

BACKGROUND In the present study, we used Doppler velocimetry in the ophthalmic artery to evaluate the hemodynamic status of the intracranial vasculature. This is the first time in the literature that indices of ophthalmic artery Doppler sonography of women with preeclampsia were evaluated before and after the use of magnesium sulfate to prevent eclampsia. CASE PRESENTATION Indices of ophthalm...

Introduction In the United States, parenteral magnesium sulfate has been used for the prevention of recurrent seizures in patients with eclampsia for over 80 years. As a natural extension to its use for the treatment of eclamptic convulsions in the United States, magnesium sulfate was then adopted for seizure prophylaxis in women with varying degrees of hypertensive disorders of pregnancy. In 1...

Because ketamine and magnesium block NMDA receptor activation by distinct mechanisms of action, we hypothesized that in a model of inflammatory pain in rats the combination of ketamine and magnesium might be more effective than ketamine alone. Antinociceptive activity was assessed by the formalin test in male Wistar rats (200-250 g). Animals were injected with 100 μL of 2.5% formalin to the pla...

BACKGROUND Studies of IV magnesium sulfate as a treatment for acute asthma have had mixed results, with some data suggesting a benefit for acute severe asthma, but not for mild-to-moderate asthma. In a multicenter cohort, this study tests the hypothesis that administration of magnesium sulfate improves pulmonary function in patients with acute severe asthma. DESIGN Placebo-controlled, double-...

Growth of Desulfovibrio desulfuricans (API strain) was found to take place in an atmosphere of hydrogen on the agar surface of complex media, including yeast extract (Difco), and Trypticase Soy Agar (BBL) without any added reducing agents. For growth on a 2% yeast extract-agar surface in the absence of hydrogen (nitrogen atmosphere), sodium lactate was required in the medium. Growth on the surf...

In this paper, the corrosion residual strength of the AZ91D magnesium alloy in the presence of sulfate-reducing bacteria is studied. In the experiments, the chemical composition of corrosion film was analyzed by a scanning electron microscope with energy dispersive X-ray spectroscopy. In addition, a series of instruments, such as scanning electronic microscope, pH-meter and an AG-10TA materials...

Objectives. We tested the hypothesis that administration of magnesium sulfate in labor protects against the development of neonatal brain lesions and cerebral palsy (CP) in low birth weight infants. Methods. Magnesium exposure was ascertained in a population-based cohort of 1105 infants weighing 2000 g or less through review of medical records of maternal magnesium sulfate administration and, w...
