Figure 6. Antioxidant enzymes (6A) SOD; (6B) CAT evaluated in X. laevis larvae exposed 192 h to control, spirulina 10 mgL^-1, diclofenac 149 µgL^-1, DCF+S 2 (diclofenac 149 µgL^-1 + spirulina 2 mgL^-1), DCF+S 4 (diclofenac 149 µgL^-1 + spirulina 4 mgL^-1), DCF+S 10 (diclofenac 149 µgL^-1 + spirulina 10 mgL^-1). Significant differences relative to: *: control; A: spirulina 10 mgL^-1; B: diclofenac 149 µgL^-1; C: DCF+S 2; D: DCF+S 4; E: DCF+S 10 (one-way ANOVA and Fisher’s test, P < 0.05).
