Pi infusion protects astrocytes from H2O2-induced cell death in a dose-dependent manner. Astrocytes were treated with different concentrations of a Pi infusion. H2O2 was added 2 h after the addition of the Pi infusion and cell death was determined 20 h later. The results are mean ± SEM of four experiments (n = 16). **P < 0.001.
