The interacellular ROS content of the oxidant-treated SK-N-MC cells. The cells were treated with either \({\text{H}}_{2} {\text{O}}_{2}\) (100 μM), menadione (12 μM) or CoCl2 (100 μM) for 24 h and then the ROS content was measured using DCFH-DA probe. The result are the mean ± SD of three experiments. Asterisk significantly different from the untreated control cells (p < 0.05)
