(a) The intracellular ROS levels measured by the DCF fluorescent intensity at excitation of 485 nm and emission of 528 nm, treated with 0.5 mM H2O2; (b) the time-resolved peroxide concentrations monitored with Raman vibration at 876 cm−1 and initial concentration of 30 mM H2O2; (c) the 8-OHdG level and (d) the GSH:GSSG ratio in the samples treated for 4 hours with moderate concentrations of H2O2 (the treatments included 6.0 μM FeSO4 as Fenton’s catalyst; asterisk and octothorp mark the statistical significance, p < 0.05).
