    Notes: Summary The effect of calcium infusion on the intravenous glucose tolerance was tested in hypocalcaemic patients suffering from renal insufficiency. It was shown that the delayed glucose disappearance rate in uraemics could be improved (p 〈 0.005) by the infusion of calcium gluconolactobionate despite the fact that the serum concentrations of potassium, urea nitrogen, and the blood pH were not altered. The basal insulin concentration was significantly depressed by the calcium infusion (p 〈 0.02). The serum calcium concentration was significantly correlated to the glucose assimilation coefficient in the uraemic patients (p 〈 0.01). — 3 hypocalcaemic patients without renal failure had a normal glucose tolerance and a normalization of the serum calcium concentration had no discernable effect. — A slight but significant decrease of the serum calcium concentration (p 〈 0.01) by EDTA-Na2 in normocalcaemic patients did not change the intravenous glucose tolerance. — It is concluded that hypocalcaemia may be one of the causes for the abnormal glucose tolerance in chronic renal failure.

    Action of insulin and glucose on the re-esterification rate of free fatty acids in isolated human fat cells (1973)

    Notes: Summary In isolated human fat cells of the greater omentum and the mammary gland, the effect of glucose, fructose, and/or insulin was tested on the re-esterification rate of FFA measured by the balance method. It could be shown that in the absence of glucose no re-esterification activity was demonstrable. Glucose alone or fructose alone stimulated the re-esterification of FFA dose-dependently in isolated fat cells of the greater omentum, and to a minor degree in fat cells of the mammary gland. Insulin had no effect on the re-esterification rate of FFA in the presence or absence of glucose or fructose, whereas it significantly stimulated the incorporation of glucose-C into CO2 and lipids. It is concluded that the re-esterification of FFA in human adipose tissue, at least in vitro, is mainly controlled by glucose without need for insulin.

    Basale und Noradrenalin-(NA-)induzierte Lipolyse in isolierten Fettzellen des Menschen bei isocalorischer und hypocalorischer Diät (1973)

    Description / Table of Contents: Zusammenfassung An isolierten Fettzellen des abdominellen Subcutanfettgewebes übergewichtiger Patienten unter isocalorischer und hypocalorischer Diät wurde die basale Lipolyse und deren Stimulierbarkeit durch Noradrenalin untersucht. Es konnte gezeigt werden, daß unter hypocalorischen Ernährungsbedingungen die basale Lipolyse auf das 4,5fache der Norm erhöht ist, und zum Unterschied von der Lipolyse unter isocalorischer Kost durch Noradrenalin nicht mehr signifikant gesteigert werden kann. Es ist anzunehmen, daß es im Hunger zu einer maximalen Aktivität der hormonsensitiven Lipase kommt, die durch maximale Dosen von Noradrenalin nicht mehr weiter stimuliert werden kann.
    Notes: Summary In isolated human fat cells of the subcutaneous abdominal region the effect of noradrenalin on lipolysis was tested under isocaloric and hypealoric diet. It could be demonstrated that with hypocaloric diet, the basal lipolysis increased 4,5-fold and could not be further stimulated by maximal doses of noradrenalin. It is suggested that starvation results in a maximal activity of the hormone-sensitive lipase, which it is impossible to further increase by noradrenalin.

    Description / Table of Contents: Zusammenfassung In isolierten menschlichen Fettzellen des abdominellen Subcutanfettgewebes wurde der Effekt einer Allgemeinnarkose im Vergleich zur Lokalanaesthesie auf die basale und Noradrenalin-induzierte Lipolyse untersucht. Es konnte gezeigt werden, daß Procainhydrochloridin vitro stark antilipolytisch wirksam war. Präinkubation des Fettgewebes mit Procainhydrochlorid hatte keinen Einfluß auf die lipolytische Aktivität in den isolierten Fettzellen. Zwischen Allgemeinnarkose und Lokalanaesthesie bestand hinsichtlich ihres Einflusses auf die Lipolyse in isolierten Fettzellen kein signifikanter Unterschied.
    Notes: Summary In isolated human fat cells of the subcutaneous abdominal region the effect of general anaesthesia as compared to local anaesthesia on basal and noradrenaline-stimulated lipolysis has been investigated. It could be shown that procain hydrochloride exerted a marked antilipolytic action when addedin vitro. Preincubation of the whole adipose tissue with procain hydrochloride prior to the isolation procedure did not alter the lipolytic activity in the fat cells. There was no significant difference in lipolysis between fat cells obtained from patients under general anaesthesia and cells from individuals under local anaesthesia with procain hydrochloride.
