    Description / Table of Contents: Zusammenfassung In der vorliegenden Untersuchung wurde das Thyrotropin-Releasing-Hormon (TRH) mit125J markiert. Die spez. Aktivität betrug 600 mCi/mg. Die chemische Integrität wurde dünnschichtchromatographisch und die biologische Aktivität im Hypophysendepletionstest nachgewiesen. Die pharmakokinetischen Untersuchungen an Mäusen ergaben eine 50% ige Verschwinderate aus dem Blut von 2′. Die höchste Radioaktivitätsanreicherung zeigte die Hypophyse. Fast ebensogroß war die Organradioaktivität in der Niere. Die Ausscheidung erfolgt hauptsächlich über den Urin. Die übrigen Organe wie Leber, Schilddrüse und Gehirn zeigten im Vergleich zu Hypophyse und Niere einen niedrigen Radioaktivitätsgehalt.
    Notes: Summary In these investigations the Thyrotropin Releasing Hormone (TRH) was labelled with125I. The specific activity calculated was 600 mCi/mg. The chemical integrity was proved by means of thinlayer chromatography and the biological activity by the pituitary depletion test. Pharmacokinetic studies in mice showed a 50% disappearance time of 2 minutes. The highest accumulation of radioactivity was achieved in the pituitary. The radioactivity content to the kidney was nearly as high as that of the pituitary.125I-TRH was found to be excreted mainly in the urine. In the liver, thyroid gland, cerebral cortex and hypothalamus the radioactivity content was low in comparison to that of the pituitary and the kidney.
