T₃ (a), T₄ (b) and 5'-DI (c) levels in serum in different groups: Ia-Se deficient control, Ib-Se deficient+HCD, IIa-Se adequate control, IIb-Se adequate+HCD, IIIa-Se excess control, IIIb-Se excess+HCD after 1 and 2 months. Data is represented as mean ± SD from 6 observations. **p<0.01, ***p<0.001 represent comparison between control and HCD groups; ^AAp<0.01, ^AAAp<0.001 comparison between 1 and 2 months; ^DDp<0.01, ^DDDp<0.001 comparison between group Ia and IIa; ^##p<0.01, ^###p<0.001 comparison between group Ib and IIb; ^Lp<0.05, ^LLp<0.01, ^LLLp<0.001 comparison between group IIa and IIIa; ^BBp<0.01, ^BBBp<0.001 comparison between group IIb and IIIb.
