Changes of SOD activity of chronic aluminum overload rat hippocampus (mean ± SD, n = 4)

Group	SOD (U · mg −1 )
Control group	10.84 ± 1.75
meloxicam 3 mg · kg−1 group	11.03 ± 1.54
meloxicam 1 mg · kg−1 group	10.22 ± 1.37
Model group	8.09 ± 0.72*
Al + meloxicam 3 mg · kg−1 group	14.99 ± 1.40#b
Al + meloxicam 1 mg · kg−1 group	9.81 ± 0.97#

^*P < 0.05, vs. control group; ^#P <0.05, vs. model group; ^bP < 0.01, vs. Al + meloxicam 1 mg · kg⁻¹ group.

SOD: superoxide dismutase.

U · mg⁻¹: Unit per mg of protein.
