Figure 1.

Effect of berberine administration to the diabetic rats on the total antioxidant capacity (TAC) in the serum. The results are presented as an arithmetical mean ± SEM. The statistical significance of the results was evaluated by ANOVA followed by Tukey’s honestly significant difference (HSD) post-hoc test. The results were considered statistically significant if p < 0.05: * p < 0.05—statistically significant difference in comparison with the NDM group; ^### p < 0.001—statistically significant difference between the DM + BRB and DM groups. NDM: non-diabetic control rats, DM: diabetic control rats, DM + BRB: diabetic rats treated with berberine at a dose of 50 mg/kg per os (p.o.) for four weeks.
