Antioxidant and Astroprotective Effects of a Pulicaria incisa Infusion

Figure 6

Pi infusion is similarly effective in attenuating ROS production when applied before or after H₂O₂. Pi infusion (12.5 μg/mL) was added to astrocytes before (−2 h, −1 h) or after (1 h, 2 h) the addition of H₂O₂. ROS levels in DCF-DA preloaded astrocytes were measured 1, 4, and 6 h after the application of H₂O₂. The results are mean ± SEM of two experiments (𝑛=6). ^∗∗𝑃<0.001.
