Effects of melatonin (M) on chronic stress-induced oxidative stress in testes. (A) ROS level relative to control group (n = 6). (B) GSH content in different groups (n = 6). (C) SOD content in different groups (n = 6). (D–E) The protein level of iNOS detected by Western blot, and relative level compared to the housekeeping molecule ACTB (n = 5). All data are presented as mean ± SEM. *P < 0.05 vs. control group; **P < 0.01 vs. control group; ***P < 0.001 vs. control group; #P < 0.05 vs. stress group; ##P < 0.01 vs. stress group; ###P < 0.001 vs. stress group. Control, non-stress treated with saline; Control+M, non-stress treated with melatonin; Stress, stress treated with saline; Stress+M, stress treated with melatonin.
