    Notes: Summary To verify the benofit of nonglucose carbohydrates and fiber in enteral formula diets we studied the postprandial metabolism of eight healthy subjects after the intake of two helpings (25 g carbohydrates each) of five commonly used enteral formulas over 4 h. There were no significant differences in postprandial concentrations of blood glucose among the formulas. The area under the curve of postprandial insulin values, however, was significantly smaller after consumption of the fructose-containing formula (1948±285 μU min ml−1, P〈0.05) than after fiber-free (3222 ±678 μU min ml−1) or two fiber-containing products (2664±326 μU min ml−1, P〈0.05; and 3040±708 μU min ml−1, P〈0.05). The insulin area of the xylitol-containing formula (2307±364 μU min ml−1) was significantly smaller compared to the fiber-free product (P〈0.05). In addition, we found the postprandial increase in triglycerides to be significantly higher after the xylitol-containing formula (from 0.93±0.14 to 1.25±0.22 mmol/1) than after the fiber-free product (from 0.82±0.13 to 0.97±0.16 mmol/1, P〈0.05) or the two fiber-containing products (from 0.88±0.16 to 0.96±0.18 mmol/1, P〈0.05; and from 0.80±0.08 to 0.95±0.10 mmol/l, P〈0.05). We conclude that a patient with type 11 diabetes may benefit from replacing glucose and glucose-equivalent carbohydrates with fructose or xylitol.

    Description / Table of Contents: Zusammenfassung Im Humanserum sind bisher zwölf verschiedene Apolipoproteine nachgewiesen worden. Apo A–I and Apo A–II sind Strukturproteine der HDL und haben Coenzymfunktion für die LCAT. Apo B ist Hauptprotein der LDL, kommt aber auch in den triglyceridreichen Lipoproteinen vor und ist verantwortlich für die LDL-Rezeptorbindung. Die C-Apolipoproteine sind Oberflächenproteine der VLDL und werden bei deren Abbau auf die HDL übertragen; gleichzeitig haben sie spezifische Wirkungen auf die Lipoproteinlipase. Diese wird auch von den E-Apolipoproteinen beeinflußt, die sowohl in triglyceridreichen Lipoproteinen wie HDL vorkommen und für die Lipoproteinbindung an einen weiteren Zelloberflächenrezeptor verantwortlich sind. Ernährung und Medikamente, Hormone und Körpergewicht, Alkohol, Zigarettenrauchen und körperliches Training und schließlich Erkrankungen von Leber und Nieren beeinflussen Konzentration und Stoffwechsel der Apolipoproteine. Abschließend werden die Zusammenhänge mit der Arteriosklerose beim Menschen besprochen.
    Notes: Summary Twelve different apolipoproteins have been described in human serum. Apo A–I and apo A–II are essential for the structure of the HDL particles and for the function of LCAT activity. Apo B is the main protein in LDL but does also occur in the triglyceride-rich particles. Apo B represents the binding protein for the LDL-receptor pathway. The C-apolipoproteins are located on the surface of VLDL. They are transferred to HDL throughout the catabolism of VLDL and affect lipoprotein lipase activity. This enzyme is also affected by the E-apolipoproteins which occur in the triglyceride-rich particles as well as in HDL. Apo E is the binding site for another specific cell receptor. The concentration and metabolism of apolipoproteins is affected by diet, drugs, hormones, body weight, alcohol, cigarettes, physical exercises, liver and renal diseases. There is a close relation between apolipoproteins and atherosclerosis.

    Description / Table of Contents: Zusammenfassung An Hanford-Miniaturschweinen wurde die In vivo-Wirkung des von uns aus Schweinehypophysen gewonnenen lipidmobilisierenden Peptid A und seiner weniger gereinigten Vorstufe Fraktion J in einer Dosierung von 100 µg/kg i.v. untersucht: Peptid A (FFS-Anstieg um 2,13 ± 0,2 mval/l) war stärker wirksam als Fraktion J (1,25 ± 0,23 mval/l). Die lipolytische Wirkung war bereits 5 min nach Injektion nachweisbar. Beide Substanzen führten zwar zu einem signifikanten Blutzuckeranstieg; nach Peptid A-Gabe war jedoch 60 min nach Injektion ein zwischenzeitlicher Glucoseabfall unter Ausgangswerte festzustellen, der mit dem Maximum der FFS zusammenfiel.
    Notes: Summary The effect of pig pituitary lipidmobilizing Peptide A and its precursor fraction J was studied in Hanford minipigs. Within 5 min after the intravenous injection of 100 µ/kg of the polypeptides free fatty acids and free glycerol were elevated; the maxima were obtained 60 respectively 30 min p.i. Peptide A was more active than fraction J (2.13 ± 0.21 respectively 1.25 ± 0.23 mval/l FFS increment compared to the initial values). Glucose was significantly elevated 210 min after the injection of either peptide, but peptide A produced a decrease of glucose 60 min p.i. when FFS were maximal.

    Notes: Summary Several lipid-mobilizing peptides occur in the pituitary, among them β-lipotropin and “lipolytic peptide A and peptide B”. The latter two peptides are distinct from β-lipotropin and appear to be chemically related to the neurophysins. Immunohistochemistry has now revealed that the lipolytic peptide B of the pituitary is localized in the ACTH- and MSH-cells. In addition, immunoreactive peptide B was found in axons of the posterior lobe of the pituitary. Immunoreactive peptide B was found also in nerve fibers and nerve cell bodies in the hypothalamus, particularly in the hypothalamo-hypophyseal tract and in the magnocellular neuronal system. Immunoreactive nerve fibers were numerous also in the periventricular nucleus of the thalamus. The antiserum against peptide B cross-reacts with neurophysin I, and hence, it cannot be excluded that at least part of the immunostaining in the brain reflects the presence of the latter component. However, the regional distribution of immunoreactive peptide B and neurophysin was not identical. Therefore, it is possible that authentic peptide B occurs not only in the pituitary but also in the brain.

    Description / Table of Contents: Zusammenfassung Mit Fraktion H ließ sich bei Kaninchen ein wirksames Antiserum (AFHS) erzeugen, das bereits in einer Menge von 0,05 ml 1000 μg Fraktion H vollständig absorbierte und die lipolytische Wirkung vollkommen aufhob. Der Antikörper (AK) im AFHS, der sich als IgG isolieren ließ, hatte in einer Konzentration von 0,08 mg den gleichen Effekt. Zwischen AFHS und den lipolytisch wirksamen Polypeptidhormonen ACTH, STH und α-MSH ließen sich keine Präcipitationslinien nachweisen. Während Fraktion H mit AFHS drei Präcipitationslinien ergab, zeigte sich bei der weiter gereinigten Fraktion J nur noch eine Präcipitationslinie mit APHS, die mit einer der drei Linien von Fraktion H das Bild der Vollidentität bot.
    Notes: Summary 0.05 ml of a potent antiserum (AFHS), we gained by immunisation of rabbits with fraction H from pig pituitaries, totally absorbed 1000 μg fraction H and completely blocked their lipolytic effect in vivo. The same could be achieved by the isolated antibody (IgG) in a concentration of 0.08 mg. There were no precipitation lines between AFHS and the polypeptides ACTH, STH and α-MSH. Instead of three lines between fraction H and APHS the purified fraction J gave only one precipitation line with APHS, which was identical with one of the lines of fraction H.
