Magnesium sulfate (medical use) solution. In the United Kingdom 4 ml of 20% solution costs the NHS about 10.23 pounds. In the United States a course of medication typically costs less than $25. Magnesium sulfate is the primary treatment and preventative measure in women with eclampsia. It lowers systolic blood pressure while maintaining diastolic blood pressure, thus leaving blood flow to the fetus uncompromised. Magnesium sulphate was once used as a tocolytic, but meta-analyses have failed to support it as an anti-contraction medication. Usage for prolonged periods (more than five to seven days) may result in health problems for the baby. In those at
Seasonal flows on warm Martian slopes water, most are not, and many appear at temperatures as low as . Some scientists think that under these cold conditions, a brine of iron(III) sulphate (Fe(SO)) or calcium chloride () is the most likely mode of RSL formation. Another team of scientists, using the CRISM instrument onboard MRO, reported that the evidence for hydrated salts is most consistent with the spectral absorption features of magnesium perchlorate (Mg(ClO)), magnesium chloride (MgCl(H2O)) and sodium perchlorate (). Experiments and calculations demonstrated that recurring slope lineae could be produced by the deliquescence and rehydration of hydrous chlorides and oxychlorine salts. However, under present
