Peroxidase activity (A) and GPx activity (B). Panel (A) densitophotometric analysis of the activities of peroxidases, a representative native gel is shown below the histogram. Where peroxidases are present, the gel remains transparent and the 3, 3, 5, 5-tetramethylbenzidine is oxidized, showing a green coloration. Abbreviations: MS = metabolic syndrome, MS + HSL = metabolic syndrome plus Hibiscus sabdariffa L., GPx = glutathione peroxidase. Data are expressed in means ± SE, (n = 8, rats in each group). Statistical significance was determined by one-way ANOVA test, followed by Tukey’s post hoc test.
