Evaluation of the Oxidative Effect of Long-Term Repetitive Hyperbaric Oxygen Exposures on Different Brain Regions of Rats

Figure 1

Oxidation products and antioxidant enzymes in brain cortex tissue. C: control group; numbers on the x-axis stand for the HBO₂ session number of the groups. One-way ANOVA: ¹ 𝑃=0.016; ² 𝑃=0.005; ³ 𝑃<0.001. Bonferroni: ^∗𝑃=0.047 versus 40-session group; ^∗∗𝑃=0.013 versus 15-, and 𝑃=0.012 versus 30-session groups; ^∗∗∗𝑃<0.001 versus 10-, 𝑃=0.001 versus 15-, and 𝑃=0.043 versus 20-session HBO₂ groups. Note that no significant changes for any measured parameters were recorded in comparison with the control values.
