    Notes: Summary Glucagon-like peptide 1 (GLP-1) (7-36 amide) is a physiological incretin hormone that is released after nutrient intake from the lower gut and stimulates insulin secretion at elevated plasma glucose concentrations. Previous work has shown that even in Type 2 (non-insulin-dependent) diabetic patients GLP-1 (7-36 amide) retains much of its insulinotropic action. However, it is not known whether the magnitude of this response is sufficient to normalize plasma glucose in Type 2 diabetic patients with poor metabolic control. Therefore, in 10 Type 2 diabetic patients with unsatisfactory metabolic control (HbAlc 11.6±1.7%) on diet and sulphonylurea therapy (in some patients supplemented by metformin or acarbose), 1.2 pmol ×kg−1×min−1 GLP-1 (7-36 amide) or placebo was infused intravenously in the fasting state (plasma glucose 13.1±0.6 mmol/l). In all patients, insulin (by 17.4±4.7 nmol ×1−1×min; p=0.0157) and C-peptide (by 228.0±39.1 nmol×1−1×min; p=0.0019) increased significantly over basal levels, glucagon was reduced (by -1418±308 pmol ×1−1×min) and plasma glucose reached normal fasting concentrations (4.9±0.3 mmol/l) within 4 h of GLP-1 (7-36 amide) administration, but not with placebo. When normal fasting plasma glucose concentrations were reached insulin returned towards basal levels and plasma glucose concentrations remained stable despite the ongoing infusion of GLP-1 (7-36 amide). Therefore, exogenous GLP-1 (7-36 amide) is an effective means of normalizing fasting plasma glucose concentrations in poorly-controlled Type 2 diabetic patients. The glucose-dependence of insulinotropic actions of GLP-1 (7-36 amide) appears to be retained in such patients.

    Description / Table of Contents: Summary This is a further contribution to clarification of the fate of various intracellular structures during storage of blood, using determination of penetration constants for the chromat stream. It has been shown that the speed of the chromat stream is an indication of the degree of cell damage, which cannot, according to the present series of observations, being completely reversed by nucleosides.
    Notes: Zusammenfassung Zur Aufklärung der intrazellulären Strukturänderung während der Blutlagerung wurde die Bestimmung von Penetrationskonstanten für den Chromateinstrom herangezogen. Es konnte gezeigt werden, daß die Geschwindigkeit des Chromateinstroms ein Maß für die Zellschädigung ist, die nach den vorliegenden Untersuchungen auch durch Nukleoside nicht vollständig rückgängig gemacht werden kann.

    Description / Table of Contents: Summary In the serum of 102 diabeties and of 96 healthy persons α2-macroglobulin concentration was measured quantitatively by radial immundiffusion technique. In diabetics the mean values were significantly higher (males 307±149 mg-%, females 315±181 mg-%) than in normals (males 257±55 mg-%, females 291±69 mg-%). Catabolic rate of α2-macroglobulin (estimated by the help of J131 labelled protein according to the method of Kluthe et al.: Experienta22, 385 (1966) ranged between 22,8 mg/kg/die in diabetics and 8,4 mg/kg/die in healthy subjects. The importance of these findings is discussed based on anamnestic and clinical data.
    Notes: Zusammenfassung Mittels radialer Immundiffusion wurde im Serum von 101 Diabetikern und von 96 Normalpersonen α2-Makroglobulin (α2-M) quantitative bestimmt. Die diabetischen Patienten wiesen mit einem Mittelwert von 307±149 mg-% (Männer) resp. 315±181 mg-% (Frauen) deutlich höhere Werte auf als Normalpersonen (257±55 mg-% resp. 291±69). Zur Frage des Zustandekommens dieser α2-M-Erhöhung wurde der Umsatz mit Hilfe von J131-markiertem Protein [nach Kluthe u. Mitarb., Experienta22, 385 (1966)] gemessen. Die katabole Rate wurde mit 8,4 mg/kg für Normalpersonen, mit 22,8 mg/kg/die für Diabetiker bestimmt. Unter der gegebenen Voraussetzung eines Stoffwechselgleichgewichts bedeutet dies, daß die α2-M-Erhöhung bei Diabetes mellitus Folge einer Synthesesteigerung ist. Die Relevanz dieser Befunde wird anhand anamnestischer und klinischer Daten diskutiert.

    Notes: Zusammenfassung Die vonCsaba undTörö angegebene Agarbindungsreaktion, die ein spezifischserologisches Krebsdiagnosticum sein soll, wurde auf Reproduzierbarkeit und ihren immunologischen Mechanismus hin untersucht. Dabei zeigte sich, daß es sich um eine unspezifische Reaktion handelt, die am ehesten einer Serumlabilitätsreaktion entspricht.

    Notes: Summary The turnover of α2-macroglobulins was measured by quantitative precipitation of the I131-marked protein, using a specific antiserum. In 6 normal persons, the half-life was found to be between 192 and 267 h. The catabolic rates in relation to the intravascular pool range between 437 and 703 mg/day

    Notes: Zusammenfassung Bei Schichtung von Seren mit 1% iger Magnesiumsulfatlösung treten bei verschiedenen Krankheiten Aggregationen im Bereich der Grenzschicht auf, die mit dem „Grenzschichtreaktiometer“ erfaßt werden können. Vergleichende Untersuchungen des Ausfalls dieser Grenzschichtreaktion mit der Blutsenkung, dem C-reaktiven Proteingehalt des Serums, dem Serumkupfer- und -eisenspiegel sowie der Takata-, Weltmann- und Thymolreaktion ergaben keine sichere Konkordanz. Es wird daher angenommen, daß der Ausfall dieser Grenzschichtreaktion von anderen Faktoren abhängig ist als die genannten Verfahren. Der diagnostische Wert der beschriebenen Grenzschichtreaktion wird diskutiert.
