    Notizen: 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.

    Notizen: Summary The main lipoprotein density classes, namely very-low-density lipoproteins (VLDL), intermediate-density lipoproteins (IDL), low-density lipoproteins (LDL), high-density lipoproteins2 (HDL2) and HDL3 were investigated with respect to their influence on hepatic lipase (HTGL) activity in vitro. Lipoproteins from pooled normal plasma (NP) and from pooled hyperlipemic plasma (HP) were prepared by means of sequential ultracentrifugation. Hepatic lipase was determined radioenzymatically after preincubation with protamine sulfate. It could be demonstrated that IDL from HP were able to stimulate HTGL activity by approximately 100% above the baseline value. HDL3 from both NP and HP revealed an inhibiting effect on HTGL activity. VLDL, LDL, and HDL2 exhibited no significant effect on HTGL activity. It is speculated that HTGL could possibly represent a second pathophysiological pathway for the catabolism of IDL in hyperlipemia but this presumption is supported by only a few investigations in vivo.

    Beschreibung / Inhaltsverzeichnis: Summary The effects of the main lipoprotein density classes on the human adipose tissue lipoprotein lipase activity were studied. A dose-dependent stimulation of lipoprotein lipase activity was obtained for HDL and, to a lesser extent, for VLDL on a constant weight basis. LDL exerted virtually no effect. At higher concentrations, HDL as well as VLDL inhibited the stimulated lipolytic activity. In type V hyperlipoproteinemia, the stimulating effect of VLDL and of HDL was significantly lower, whereas the inhibiting action of HDL was markedly increased.
    Notizen: Zusammenfassung Die Effekte der einzelnen Lipoproteidfraktionen des Plasmas auf die Aktivität der Lipoproteidlipase des menschlichen Fettgewebes wurden untersucht. HDL (high density lipoproteins) und, in geringerem Ausmaß, VLDL (very low density lipoproteins) bewirkten eine dosisabhängige Stimulierung der Aktivität der Lipoproteidlipase. LDL (low density lipoproteins) übten praktisch keinen Effekt aus. In höheren Konzentrationen hemmten sowohl HDL als auch VLDL die stimulierte lipolytische Aktivität. Bei Patienten mit Hyperlipoproteinämie Typ V war der stimulierende Effekt der VLDL und HDL viel geringer, die Hemmwirkung der HDL jedoch deutlich stärker ausgeprägt.

    Notizen: Summary 12 patients with unequivocal post-alcoholic end-stage liver cirrhosis were compared with 12 healthy controls with regard to the plasma concentrations of lipids, lipoproteins (by rate zonal ultra-centrifugation) and apolipoproteins of high-density-lipoproteins (HDL) (by disc electrophoresis), as well as to the activities of lecithin-cholesterol acyltransferase (LCAT) in plasma and of hepatic lipase (HL) in post-heparin plasma. The cirrhotic group showed the following differences (all significant at thep〈0.01 level) from the control group: Total cholesterol, HDL-cholesterol, very-low-density-lipoproteins (VLDL), HDL, and HL were decreased. Intermediate-density-lipoproteins (IDL) were not detectable in the cirrhotic group. Low-density-lipoproteins (LDL) did not differ significantly from controls. However, LDL from cirrhotic patients contained more triglycerides but less esterified and free cholesterol (allp〈0.01). The percentage apolipoprotein composition of HDL did not differ significantly between controls and cirrhotics. Surprisingly, LCAT acivity in plasma as well as the ratios between esterified and free cholesterol in plasma, LDL, and HDL were nearly identical in both groups. It seems likely that LCAT activity decreases only in the states of acute or subacute liver injury or of biliary obstruction. Severe chronic liver damage as in our cases of end-stage liver cirrhosis without any signs of acute liver injury exhibits apparently no defect in cholesterol esterification.

    Beschreibung / Inhaltsverzeichnis: 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.
    Notizen: 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.

    Notizen: Summary An assay of lipolytic activity in human adipose tissue is described, in which native homogenates of the adipose tissue yield the enzyme, as well as the triglyceride substrate, and the emulsifying phospholipids. The lipolytic activity in the presence of serum is characterized mainly as lipoprotein lipase activity by a pH-optimum of 8.0, by the fact that serum is necessary for full activity, and that it is inhibited by 1 M NaCl and by protamine. At serum concentrations of higher than 50% a marked inhibition of the lipolysis is observed. Noradrenaline, insulin, and heparin have no effect on the serum-stimulated lipolytic activity.
