Antioxidant and Astroprotective Effects of a Pulicaria incisa Infusion

Figure 2

Time course of the protective effect of the Pi infusion on astrocytes. Astrocytes were preincubated with the Pi infusion (100 μg/mL) for 2 h. H₂O₂ was then added and cytotoxicity was measured at the indicated time points. The results are the means ± SEM of four experiments (𝑛=16). ^∗∗𝑃<0.01,^∗∗∗𝑃<0.001, compared to cells treated with H₂O₂ only.
