    Notes: [Auszug] When polysomes were incubated with constant amounts of soluble cell fraction, the incorporation of 14C-glycine increased only slightly and by no means in proportion to the amount of polysomes added. Thus incubation of polysomes with 0-4 ml. of 105,000*7 supernatant (80 mg-equivalents) showed ...

    Description / Table of Contents: Summary 1. A method allowing the simultaneous determination in serum of the socalled free and the protein bound part of 1-triiodothyronine-131I added in vitro, using dextran gel filtration, is presented. Assessment of serum protein binding and transport of triiodothyronine can be conveniently performed for clinical purposes by this procedure. 2. In socalled discharge experiments non-labelled triiodothyronine is added to incubation mixtures of serum and l-triiodothyronine-131I. The amount of added triiodothyronine did not exhaust the total binding capacity of serum proteins for triiodothyronine. In contrast to the behaviour of the percentages of socalled free and protein bound triiodothyronine the absolute amount of protein bound triiodothyronine was rising linearly with rising concentrations of triiodothyronine added. The curve obtained was interpreted as resulting from saturation curves of different triiodothyronine binding proteins and discharge curves of competitively bound substances, e.g. thyroxine. 3. Dextran gel is not acting merely as molecular sieve for triiodothyronine, but rather competing actively with serum proteins for triiodothyronine, adsorbing the latter. The physiological rôle of the socalled free triiodothyronine is discussed. 4. With addition of l-thyroxine-131I 80% of131iodine was recovered, when the method ofBarker for determination of serum protein bound127iodine (open alkaline ashing) was used.
    Notes: Zusammenfassung 1. Es wird eine Methode zur gleichzeitigen Bestimmung des sog. freien und des proteingebundenen Anteils von in vitro zugesetztem L-Trijodthyronin-131Jod im Serum mittels Dextran-Gel-Filtration angegeben. In der beschriebenen Form ist diese Technik für die routinemäßige Anwendung in der Klinik zur Bestimmung der Bindungs- und Transportverhältnisse von Trijodthyronin geeignet. 2. In sog. Verdrängungsversuchen wurde nichtmarkiertes Trijodthyronin dem Inkubationsgemisch von Serum und L-Trijodthyronin-131Jod zugesetzt. Die zugesetzten Trijodthyroninmengen erschöpfen die Gesamtbindungskapazität der Serumproteine in dem gewählten Konzentrationsbereich keineswegs. Im Gegensatz zum Verhalten der prozentualen Anteile des sog. freien und des proteingebundenen Trijodthyronins steigt die absolute Menge des proteingebundenen Trijodthyronins dabei steil an. Man findet eine Kurve, die nicht einer einfachen Sättigunskurve entspricht, sondern eine Resultante aus Sättigungskurven verschiedener Trijodthyronin-bindender Proteine und Verdrängungskurven kompetitiv gebundener Substanzen (z.B. Thyroxin) darstellt. 3. Dextran-Gel wirkt nicht als einfaches Molekülsieb für Trijodthyronin. Es greift vielmehr durch Adsorptionsvorgänge kompetitiv in die Serumproteinbindungsverhältnisse des Trijodthyronins ein. Die physiologische Bedeutung des sog. freien Anteils an Trijodthyronin wird diskutiert. 4. Die Methode zur Bestimmung des proteingebundenen Jods (PB127I) mittels alkalischer offener Veraschung (Barker) wurde technisch vereinfacht und bezüglich ihrer Reproduzierbarkeit untersucht. Die131Jodausbeute aus zugesetztem L-Thyroxin-131Jod lag bei diesem Verfahren bei ca. 80%.

    Description / Table of Contents: Summary 3H-β 1–23 corticotropin was bound to dextran gel (sephadex G-25) and was eluted by either serum proteins, albumin or 0.1 N HCl. Competitive binding of3H-ACTH to serum proteins (albumin) and dextran gel was shown by dextran gel filtration. Likewise natural ACTH (pig) and endogenous ACTH from plasma of an adrenalectomized patient were shown to be partly protein bound using biological ACTH-assay.
    Notes: Zusammenfassung 3H-β 1–23-Corticotropin wurde an Dextrangel (Sephadex G-25) gebunden und konnte durch Serumproteine, Albumin oder 0,1 N HCl eluiert werden. Mittels Dextrangelfiltration wurde gefunden, daß3H-ACTH kompetitiv an Serumproteine (Albumin) und Dextrangel gebunden wurde. Auch für natürliches Schweine-ACTH und endogenes ACTH in Patientenplasma (Adrenalektomie) wurde mittels biologischer ACTH-Bestimmung die Bindung von ACTH an Proteine bestätigt.

    Description / Table of Contents: Summary A group of clinically euthyroid obese patients was found to have significantly lower PBI-values (4,47 γ-%) than controls (5,09 γ-%). Binding of triiodothyronine-125I to serum proteins as estimated by dextran gel filtration was significantly increased in the obese group (87,64 vs. 84,98%).
    Notes: Zusammenfassung Das proteingebundene Jod im Serum wurde bei einer Gruppe von adipösen Patienten im Mittel signifikant vermindert gegenüber dem Mittelwert eines Normalkollektivs gefunden. Die Bindung von Trijodthyronin-125Jod an Serumproteine war bei Adipositas signifikant erhöht.

    Description / Table of Contents: Summary A case of ectopic ACTH syndrome is reported presenting with hypercorticism and pronounced hypokalemic alkalosis in a woman aged 55 y. with metastatic cancer of the pancreas. The failure to show a significant difference of plasma ACTH-levels from bulbus superior venae jugularis resp. femoral vein supported the clinical assumption of non pituitary origin of elevated plasma ACTH.
    Notes: Zusammenfassung Es wird über einen Fall von ektopischem ACTH-Syndrom mit Hypercortizismus und hypokaliämischer Alkalose bei einem metastasierten Pankreas-Carcinom berichtet. Das Fehlen einer Differenz zwischen den ACTH-Spiegeln im Plasma aus dem Bulbus cranialis venae jugularis und aus der Vena femoralis unterstützte die Annahme einer nicht hypophysären Herkunft der erhöhten ACTH-Spiegel.
