Figure 2.

Effect of NGZ on DOX-induced MDA production (Figure 2A) and reactive oxygen species (ROS) generation (Figure 2B) in H9c2 cells. Cells were pretreated with different concentrations of NGZ for 4 hr before exposure to 5 µM of DOX for 24 hr. Data are expressed as mean ± SEM of three separate experiments ^###P<0.001 versus control, *P<0.05, **P<0.01 and ***P<0.001 versus DOX
