SOD1 and ganglioneuroma: The SOD activity (Figure 4B) in the GN group was significantly decreased compared to the control (1.29 ± 0.17 U/gPr vs. 4.74 ± 0.13 U/gPr, p < 0.05), whereas in the other four groups (only antioxidants and with combination), the levels of SOD activity were similar to the controls (3.81 ± 0.18 U/gPr and 5.01 ± 0.36 U/gPr, respectively, for the antioxidants alone, p < 0.05) and (3.98 ± 0.22 U/gPr and 4.23 ± 0.21 U/gPr, respectively, for the combinations, p < 0.05), Figure 4B).
