The ROS level in control, 0.04 mM, 0.16 mM and NAC groups (a). The activity of CAT (b) and SOD (c) induced by isoniazid. The concentration of MDA (d), ROS (e) and apoptosis level (f) in different treated groups. The unit of SOD and CAT were ul/mg protein while MDA nmol/mg protein. The concentration of ROS was normalized to 0 mM groups. The red arrows represented the pericardial areas. *P < 0.05, **P < 0.1, ***P < 0.001, ns means no significance
