MDA levels in the experimental PD model treated with cilazapril and benazepril. The effects of different doses (0.32 µM–5.12 µM) of (a) cilazapril and (b) benazepril on the cellular MDA (malondialdehyde) levels were evaluated. In the 6-OHDA-induced oxidative stress model, significantly lower MDA levels were observed in the ACE inhibitor groups than in the control, DMSO and 6-OHDA groups (*p < 0.05), **p < 0.01).
