I Effect of melatonin (MLT) and irradiation (IR) on the oxidative stress markers, including A 4-hydroxynonenal (4-HNE), B 8-Hydroxyguanosine (8-OHdG), and C hydrogen peroxide (H2O2) concentrations, in the testicular tissues of rats in the control and different treatment groups. Values are expressed as mean ± SEM (n = 5). ** Highly significant at P < 0.01. ***, ###, %%%, @@@ Very Highly significant at P < 0.001. **& *** Significant as compared with the control 3 days group. #, ### Significant as compared with the control 14 days group. %%% Significant as compared with the IR 3 days group. @@@ Significant as compared with the IR 14 days group.
