Figure 4.

The protective effect of red beetroot extract (RBR) on the cortical lipid peroxidation (MDA), glutathione (GSH) content, nitric oxide (NO), and inducible nitric oxide synthase (iNOS) expression in response to chlorpyrifos (CPF) exposition. Data are expressed as mean ± SD (n = 7); P values < 0.05 indicate statistical significance. A; Significant change versus the control group, B; significant change versus the CPF-injected group. Results of iNOS mRNA expression are expressed as mean ± SD of triplicate assays and were normalized to GAPDH and expressed as fold change (log2 scale), with respect to mRNA levels in the control and the CPF groups.
