    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.

    Notes: Summary Profound biological changes occur in patients treated with interferon. Observations of endocrine changes prompted us to examine the effects of subcutaneous alpha-interferon administration in single doses on circulating levels of thyroid stimulating hormone, total thyroxine, and total triiodothyronine in 10 volunteers (5 healthy subjects and 5 patients with hepatitis C). Blood samples were taken on an out-patient basis immediately before and 2, 12, 24, 48, and 72 h after administration of 1, 3, or 5 × 106 units of recombinant alpha-interferon. Application of the different dose levels was randomly assigned. Plasma samples were stored at −80°C; after collection of samples had been completed hormone levels were measured using commercially available test kits. At all time points before and after injection of alpha-interferon, standard deviations of measured hormone levels of healthy control subjects and patients overlapped to a considerable extent. At a dose level of 5 × 106 units, alpha-interferon significantly increased cortisol levels as described, and decreased the level of thyroid stimulating hormone in the group receiving alpha-interferon as compared to placebo-treated healthy volunteers. The effects occurred 12 h after injection. Maximum suppression of thyroid stimulating hormone levels was observed 24 h after injection, when serum levels of thyroxine and triiodothyronine also were significantly reduced. We conclude that subcutaneous alpha-interferon treatment with doses as low as 5 x 106 units affects the control of thyroid function.
