Deltamethrin-induced oxidative stress and biochemical changes in tissues and blood of catfish (Clarias gariepinus): antioxidant defense and role of alpha-tocopherol

Table 3 Effects of deltamethrin and α-tocopherol on Liver, kidney and gill catalase activity in catfish

Groups	Liver catalase (u/g. tissue)	Kidney catalase (u/g tissue)	Gill catalase (u/g tissue)
Controls	0.26 ± 0.012^(a)	0.35 ± 0.01^(a)	0.33 ± 0.009^(a)
Deltamethrin (0.75 μg/l)	0.16 ± 0.019^(b)	0.29 ± 0.011^(b)	0.25 ± 0.012^(b)
α-tocopherol (12 μg/l)	0.27 ± 0.021^(a)	0.35 ± 0.012^(a)	0.34 ± 0.014^(a)

(u/g.) Unit/gm tissue.
Values are expressed as means ± SEM (standard error mean).
Means with different superscripts are significantly different (p < 0.05), while means with the same superscripts indicate non-significant changes.
