    Description / Table of Contents: Résumé La signification de la courbe pointue («lagcurve») c-à-d celle dans laquelle le sucre sanguin monte rapidement à partir de la valeur normale à jeun à plus de 180 mg/100 ml mais retourne à la valeur à jeun en 120 min, reste controversée. Pour étudier cela plus profondément, le taux de l'insuline plasmatique a été mesuré par dosage radio-immunologique, pendant des épreuves de tolérance au glucose orales et intraveineuses, chez trois groupes de sujets comparables en ce qui concerne l'âge et le poids. Groupe 1, 14 avec des courbes pointues inexpliquées [(lagstorage curves) caractéristique de l'absorption intestinale rapide]. Groupe 2, 14 avec des courbes pointues à la suite d'une intervention chirurgicale gastrique. Groupe 3, 14 sujets normaux. Le taux moyen d'insuline était plus élevé dans le groupe 1 que dans le groupe 3, mais le stimulus hyperglycémique était plus grand. La réponse insulinique dans le groupe 2 n'a pas différé des témoins d'une façon significative. La courbe moyenne du sucre sanguin était semblable dans les groupes 1 et 2, mais en dépit de ceci, la réponse insulinique était significativement prolongée dans le groupe 1 suggérant un degré de résistance ou d'antagonisme insulinique. Dans les épreuves intraveineuses, 2 malades de chacun des groupes 1 et 2 avaient une valeur K dans le domaine des valeurs diabétiques. La valeur moyenne de K était plus élevée dans le groupe 1 que dans le groupe 2. Les deux groupes montraient une réponse insulinique semblable mais plutôt basse.
    Abstract: Zusammenfassung Die Bedeutung von spitzgipfligen Blutzuckerkurven, die von normalen Nüchternspiegeln auf mehr als 180 mg% ansteigen, um in 120 min auf die Ausgangswerte zurückzukehren, bleibt strittig. — Um diese Frage weiter zu klären, wurden imnumologisch die Plasma-Insulinwerte bei 3 Gruppen von je 14 Probanden gemessen, die nach Alter und Gewicht übereinstimmten: Gruppe 1 bestand aus Probanden mit derartigen Kurven ohne ausreichende Erklärung, Gruppe 2 aus Patienten nach Magenoperationen und Gruppe 3 diente als Vergleichskollektiv. Im Teilkollektiv 1 fanden sich höhere Insulinwerte als in 3, doch bestand gleichzeitig eine stärkere Blutzuckererhöhung als Stimulans. Die Insulinausschüttung in der Gruppe 2 unterschied sich nicht signifikant vom Vergleichskollektiv. In den Gruppen 1 und 2 stimmen die Blutzuckerspiegel weitgehend überein, doch hielt die Erhöhung der Insulinkonzentration in Gruppe 1 signifikant länger an, was auf einen gewissen Grad von Insulin-Resistenz oder -Antagonismus schließen läßt. Bei der i.v. Belastung ergaben sich für je 2 Probanden der Gruppen 1 und 2k-Werte im diabetischen Bereich. In Gruppe 1 lagen die mittlerenk-Werte höher als in Gruppe 2. Beide Teilkollektive zeigten eine eher erniedrigte Insulin-Ausschüttung.
    Notes: Summary The significance of the lag curve, i.e. one in which the blood sugar rises rapidly from a normal fasting value to more than 180 mg/100 ml but returns to the fasting value within 120 min, remains controversial. In order to study this further, plasma insulin levels were measured by immunoassay during oral and intravenous glucose tolerance tests in 3 groups of age/weight matched subjects: Group 1, 14 with unexplained lag curves: Group 2, 14 with lag curves following gastric surgery and Group 3, 14 normal subjects. The mean insulin levels were higher in Group 1 than in Group 3 but the hyperglycaemic stimulus was greater. The insulin response in Group 2 did not differ significantly from the controls. The mean blood sugar curves were similar in Groups 1 and 2, but despite this the insulin response was significantly prolonged in Group 1, suggesting a degree of insulin resistance or antagonism. In the intravenous test 2 patients from each of Groups 1 and 2 had aK value in the diabetic range. The meanK value was higher in Group 1 than in Group 2. Both groups showed a similar rather low insulin response.
