Effect of melatonin pre-treatment on DNA strands breaks of testes in mice exposed to whole-body 60Co γ-irradiation. An alkaline comet assay was performed to analyzed DNA strands breaks after 2h, 4h and 8h post-irradiation. DNA strands breaks are represented as tail length, tail moment, olive moment and % DNA in tail. *p < 0.01, **p < 0.001, ***p < 0.05, ns = non-significant (p > 0.05)
