Perfusion with Magnesium Sulfate Increases sFlt-1 Secrtion Only in the Fetal Side of Placenta of Women with Preeclampsia.
Summary of "Perfusion with Magnesium Sulfate Increases sFlt-1 Secrtion Only in the Fetal Side of Placenta of Women with Preeclampsia."
Abstract Objective: To examine the effect of magnesium sulfate (MgSO4) on sFlt (soluble fms-like tyrosine kinase)-1 in the fetal and maternal compartments of normotensive and preeclamptic placentas. Methods: Cotyledons of term normotensive and preeclamptic placentas were dually perfused for six hours, with control medium and MgSO(4) (6-7 mg %) in the maternal reservoir. Perfusate sFlt-1 concentrations were measured. Results: Median sFlt-1 concentration was higher in the maternal than in the fetal side in both groups and perfusion media (p<0.0001). 2) When perfused with control medium the maternal side median sFlt-1 concentration was higher in the preeclampsia than in the control group (p<0.0001). After pefusion with MgSO(4): The median maternal and fetal sides perfusate sFlt-1 concentration were higher in the preeclampsia than in the control group (p<0.0001). In comparison to perfusion with control medium, the median sFlt-1 concentration of normal pregnant women decreased in the fetal and increased in the maternal side. In the preeclampsia group, only median fetal side sFlt-1 concentration increased. Conclusion: In contrast to normal pregnant women, perfusion with MgSO(4) of preeclamptic placentas did not increase their sFlt-1concentration. This may indicate that MgSO(4) role may be limited to its anti eclamptic and does not affect the anti-angiogenic state associatede with preeclampsia.

Medical and Biotech [MESH] Definitions
Chondroitin Sulfates
Derivatives of chondroitin which have a sulfate moiety esterified to the galactosamine moiety of chondroitin. Chondroitin sulfate A, or chondroitin 4-sulfate, and chondroitin sulfate C, or chondroitin 6-sulfate, have the sulfate esterified in the 4- and 6-positions, respectively. Chondroitin sulfate B (beta heparin; DERMATAN SULFATE) is a misnomer and this compound is not a true chondroitin sulfate.
Sulfate Adenylyltransferase
An enzyme that catalyzes the activation of sulfate ions by ATP to form adenosine-5'-phosphosulfate and pyrophosphate. This reaction constitutes the first enzymatic step in sulfate utilization following the uptake of sulfate. EC 2.7.7.4.
Magnesium Chloride
Magnesium chloride. An inorganic compound consisting of one magnesium and two chloride ions. The compound is used in medicine as a source of magnesium ions, which are essential for many cellular activities. It has also been used as a cathartic and in alloys.
N-acetylgalactosamine-4-sulfatase
An arylsulfatase that catalyzes the hydrolysis of the 4-sulfate groups of the N-acetyl-D-galactosamine 4-sulfate units of chondroitin sulfate and dermatan sulfate. A deficiency of this enzyme is responsible for the inherited lysosomal disease, Maroteaux-Lamy syndrome (MUCOPOLYSACCHARIDOSIS VI). EC 3.1.6.12.
Magnesium Oxide
Magnesium oxide (MgO). An inorganic compound that occurs in nature as the mineral periclase. In aqueous media combines quickly with water to form magnesium hydroxide. It is used as an antacid and mild laxative and has many nonmedicinal uses.
