    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 Es wird über die Gewinnung und weitere säulenchromatographische Reinigung einer lipolytisch wirksamen Substanz aus Schweinehypophysen (Fraktion H) berichtet. Auf Grund der untersuchten physikalisch-chemischen Eigenschaften kann gesagt werden, daß diese Substanz mit der vonRudman et al. extrahierten Fraktion H identisch ist. Durch Chromatographie an Sephadex G 50 konnte die Fraktion weiter gereinigt werden; die lipolytische Aktivität pro Gewichtseinheit wurde dadurch von 0,3 Μg auf 0,1 Μg in vitro bzw. von 125 Μg auf 63 Μg in vivo als minimal wirksame Dosen gesteigert, wie Untersuchungen an Meerschweinchen und Kaninchen ergaben. Eine Kontamination mit lipolytisch wirksamen Mengen ACTH wurde durch säulenehromatographische Untersuchungen auf Sephadex G 50 weitgehend ausgeschlossen.
    Notes: Summary The extraction and further purification of a lipolytic substance from hog pituitaries (Fraction H) are reported. This substance has physico-chemical properties identical with Fraction H extracted from pituitaries of pigs byRudman et al. Further purification was achieved by Sephadex-chromatographie. The lipolytic activity in the rabbit was augmented in vitro to 0.1 Μg/ml and in vivo to 63 Μg as minimal effective dose. A contamination with ACTH could be excluded by chromatography on Sephadex G 50.

    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.
