Variation by groups of serum antioxidant capacity: (a) Catalase and (b) TAC (total antioxidant capacity) by groups. Notes: The circles represent the individual values, and the horizontal line is given by the median. Abbreviations: C, Control; G, Gentamicin; GCC1, Gentamicin and CC1 solution; GCC2, Gentamicin and CC2 solution; GLCC1, Gentamicin and LCC1 solution; GLCC2, Gentamicin and LCC2 solution; The letter codes correspond to the p-values < 0.006: a G compared to C; c G compared to GCC2; d G compared to GLCC1; e G compared to GLCC2; B GCC1 compared to GLCC1; X GCC2 compared to GLCC2.
