Effect of Hypoxia on the Calcium and Magnesium Content, Lipid Peroxidation Level, and Ca²⁺-ATPase Activity of Syncytiotrophoblast Plasma Membranes from Placental Explants

Figure 1

Panels (a) and (b). Ca²⁺ and Mg²⁺ content of syncytiotrophoblast plasma membranes (BM and MVM, resp.) prepared from freshly prepared placental explants and then incubated with different concentrations of Ca²⁺. Values expressed as means ± S.E., for . Panels (c) and (d). Level of lipid peroxidation, determined as TBARS, and PMCA activity, respectively, of syncytiotrophoblast plasma membranes (BM and MVM) prepared from freshly prepared placental explants and then incubated with different concentrations of Ca²⁺. Values expressed as means ± S.E., for . versus 0 CaCl₂.
