Iodine liver content

The supply of 10 mg I kg in the mineral mixtures of farm animals increased the iodine content of the thyroid gland, milk and eggs significantly, but did not greatly affect the iodine concentration of meat and liver (Anke et al. 1989b, c, Wenk and Heinrich 1989). 

Effects of ID in adult rats Feeding adult rats a diet with a low iodine content (LID) (0.02-0.06 pg I / g) results in undetectable circulating T4 levels, increased TSH and unaltered T3 concentrations, the same changes described for inhabitants of areas with severe ID. T4 decreases in all tissues studied so far (liver, brain, heart, and skeletal muscle) to the same degree as in plasma In contrast, T3 does not remain normal in tissues, as it does in plasma. T3 levels decrease, although not as markedly as T4 T3 in nuclei from liver and brain decrease 2- 2.5-fold with respect to nuclear T3 in rats on the I-supplemented LID (LID+I) All biological end-points of thyroid hormone action...
