[Effect of change of habitat (sea and fresh water) on in vivo thyroglobulin synthesis in Atlantic glassed eels (Anguilla anguilla L.)].
Thyroid biosynthesis in glassed eels (Anguilla anguilla L.) was studied to establish whether salinity changes could affect it, when they live in sea water or in fresh water containing 125I. Aqueous extrait of homogenized cephalic heads of glassed eels contains an iodinated protein 17-19 S having thyroglobulin-like properties and including iodotyrosins (MIT and DIT) and thyroid hormones (3 and T4). Biosynthesis of this proteins is roughly twice more important in fresh water than in sea water at 19-21 degrees C and its specific radioactivity (125I) is practically double in fresh water.
