    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 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.

    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.

    Description / Table of Contents: Zusammenfassung Aus Hypophysen vom Schwein wurde eine als Peptid A bezeichnete Substanz dargestellt, die sich unter den angegebenen Bedingungen als einheitlich in Säulenchromatographie, Acetatfolien- und Acrylamidgelelektrophorese, Ultrazentrifuge sowie im Immunodiffusionstest erwies. Das mit der Ultrazentrifuge bestimmte Molekulargewicht lag bei 5700. Die minimal wirksame Dosis betrug bei Kaninchen in vitro 0,1 Μg/ml. Nach den vorliegenden Untersuchungen ist anzunehmen, daß Peptid A von MSH, ACTH, STH und TSH verschieden ist.
    Notes: Summary A substance called Peptide A was prepared from pig pituitaries. With the conditions used this substance proved to be homogeneous by column chromatography, acetate and acrylamide gel electrophoresis, ultracentrifugation as well as in the immuno diffusion test. By means of the ultracentrifuge a molecular weight of 5700 was determined. The minimum effective dose in rabbits was 0.1 Μg/ml in vitro. According to the information so far available it would seem that Peptide A differs from MSH, ACTH, STH and TSH.
