Amniotic and allantoic fluid concentrations of thyroxine, 3,3',5'-tri-iodothyronine, 3,3'-di-iodothyronine and 3',5'-di-iodothyronine in the pig during the period of gestation



Amniotic and allantoic fluid concentrations of thyroxine, 3,3',5'-tri-iodothyronine, 3,3'-di-iodothyronine and 3',5'-di-iodothyronine in the pig during the period of gestation



Journal of Endocrinology 147(2): 245-251



Thyroxine (T4), 3,3',5'-triiodothyronine (reverse T3; rT3) and di-iodothyronines (3,3'-T2 and 3',5'-T2) were measured in pig amniotic fluid (AF) and allantoic fluid (Al) between 32 and 113 days of normal pregnancy. Low but measurable quantities of T4 in AF and Al (2.1+or-0.3 and 3.2+or-0.5 nmol/litre respectively) were found before the onset of fetal thyroid gland function, which indicates the material source of T4.
