[Metabolism of radioiodine in Xenopus thyroid during larval life and metamorphosis].
Radioiodine uptake and metabolism study show variations in the functional state of thyroid glands of Xenopus through larval development. During metamorphic climax, the level of hormone synthesis is the highest ; after metamorphosis, labeled thyroid hormones proportion decreases significantly. Normal metamorphosis sequences depend on the gland functional state changes.
