Copper Chaperone for Cu/Zn Superoxide Dismutase is a sensitive biomarker of mild copper deficiency induced by moderately high intakes of zinc

Table 3 Effect of dietary Zn and Cu on plasma Cu concentration and Cp activity of rats

¹ Non-responders had a range of 667.6 – 1291.6 μg/L.
² Responders (range <0.1 – 572.4 μg/L) were those animals having plasma Cu concentration lower than 2SD below the mean plasma copper concentration of animals in the Zn-30 diet group (Zn-30; mean ± SD = 975.0 ± 159.4 μg/L).
³ Non-responders had a range of 65.3 – 152.8 U/L.
⁴ Responders (range <0.1 – 57.8 U/L) were those animals having Cp activity lower than 2SD below the mean Cp activity of animals in the Zn-30 diet group (Zn-30; mean ± SD = 106.5 ± 23.9).
⁵ No. of responders were compared using the Fisher exact test. For each diet group, No. of responders without a common letter differ, P < 0.05.
