In 65 normal pregnant protein iodine numbers are determined via the technique of chloric acid. In the first trimester of pregnancy is an average value of 8.82 ug%; in the second quarter 10 ug% in the third quarter and 11.99 ug%; These elevations Iodine protein in normal pregnancy as due to increased estrogen, in turn, cause an increase in transport capacity of the thyroid hormone binding proteins, not increasing the free thyroxine are interpreted, which explains the absence of clinical symptoms of hyperthyroidism.

Plasma determination is made at baseline of 17-hydroxycorticoids free in 39 subjects sea level (Lima) and 30 subjects in chronic hypoxia (Morococha 4,540 mts.). In the group of sea level Mean ± SD was 13.7 ± 4 .09 ug% with extreme values of 6.8 ug ug% and 23.2%. In the group height Mean ± S.D. was 18.7 ± 7.93 ug% with extreme values of 5.1 and 33.8%. The differences between the means of both groups have statistical significance. Accepting the possibility of unspecified pigments can distort these determinations in the group of high, also it raises the possibility that higher values of this group are actually translation of chronic stress by chronic hypoxia.
