Figure 5.
Effects of 5 or 10 days of ELF-MF exposure (1 mT, 50 Hz) on the survival of SH-SY5Y neuroblastoma cells after a 2-h incubation with 35 μM H2O2. Values were expressed as means ± s.d. A 20% decrease of alive cells (IC20) was calculated through a 4P-logistic regression derived from a dose-response curve obtained by incubating unexposed cells with H2O2 concentrations ranging from 0 to 200 µM (inset diagram). ***P < 0.001 (2 × 2 × 2 factorial ANOVA followed by post-hoc Newman–Keuls/Tukey tests for multiple comparison).
