FIG. 2.
Measurement of ROS and 4-HNE production in cortical neuronal cell cultures (a) and brain stem cell cultures (b). ROS production was determined after 30 min of treatment, and 4-HNE production was determined after 24 h of treatment. Statistical analysis was done with Student's t test. ∗, P ≤ 0.05; ∗∗, P ≤ 0.01.
