Abstract Results are reported from studies of the transmission of thyroxine, its analogs and isomers, through the placental membrane using I/sup 131/ as a tracer. Some physiological properties of tagged isomers and analogs of thyroxine are reported. It was concluded that they are decreased in cord blood although there is complete transmission of NaI/sup 131/. There seems to be a specific distributional difference between thyroxine and triiodothyronine in its collections in body areas. Excretion in bile and rapid re-absorption in the gut were shown. (auth)
