We evaluated the protective effect of N-acetylcysteine (NAC) on immunity system irradiated by 12C6+ ion beam. Kun-Ming mice were whole-body irradiated by 12C6+ ion at doses of 0, 0.5, 1, 1.5, 2, 2.5 and 3 Gy. The results showed that in saline group, the lymphocytes DNA double-strand breaks (DSBs), maleic dialdehyde, thymocytes number in G0/G1 and apoptosis percentage increased with dose increment, and the levels of interferon-γ, glutathione, superoxide radical (SOD) and natural killer cells activity decreased with dose increment. However, there were no significant changes in NAC-treated group. The data indicated that pre-treatment with NAC could significantly remove the ROS by counteracting the glutamate, decrease excessive lipid peroxidation reaction and SOD damages, and protect DNA, lymphocytes and cytokines against irradiation.
