    Description / Table of Contents: Zusammenfassung Das Studium von 17 Fällen, bei denen eine Frühpankreatektomie durchgeführt wurde, bestimmt wie folgt unser therapeutisches Verhalten: Bei der akuten postoperativen Pankreatitis sind wir angesichts des schwerwiegenden Krankheitsverlaufes überzeugt von der Notwendigkeit einer frühzeitig durchzuführenden ausgedehnten Pankreatektomie. Bei der akuten primären Pankreatitis sind wir etwas zurückhaltender, da selbst bei offener Bauchhöhle das Schicksal gewisser Pankreaspartien nicht mit Sicherheit vorhergesagt werden kann. Dennoch bestimmen unsere im Vergleich mit den Literaturangaben günstigen persönlichen Erfahrungen mit der Pankreatektomie unser aktives chirurgisches Vorgehen bei der akuten nekrotisierenden hämorrhagischen Pankreatitis.
    Notes: Summary The study of 17 cases of acute pancreatitis, in whom early total or subtotal pancreatic resection were performed, has led to the following therapeutic principles: the serious nature of acute post-operative pancreatitis has convinced us of the necessity for early intervention and as extensive a resection as possible; 5 out of 6 patients were cured in this way. In case of acute primary pancreatitis we are more conservative since even at laparotomy it is difficult to foresee the fate of all parts of the pancreas. Nevertheless our relatively favorable results led us to intervene surgically if the signs and symptoms of pancreatitis do not show any improvement after 8 to 12 h. If acute, diffuse pancreatitis affects the whole organ subtotal pancreatectomy is performed. If the head of the pancreas is affected we confine ourselves to the removal of necroses. Duodenopancreatectomy does not seem justified in the acute phase; only 1 out of 3 patients survived this procedure.

    Notes: Different designs of injection and restriction devices for capillary supercritical fluid chromatography (SFC) have been investigated with respect to their practical applicability and usefulness for reproducible and accurate qualitative and quantitative analyses. In combination with a self-made instrument a fast switching valve is preferable as an injection device compared to a split-injector, and an integral restrictor made from the end of the fused silica (FS) separation column was superior to a linear restrictor made by coupling a small diameter FS-column to the separation column.

    Description / Table of Contents: By interaction of alkali pentacarbonyl chromates(-II) with aromatic mono-, di-, and triamines at room temperature only pentacarbonyl amine chromium(0) compounds are formed. Wheras m- and p-phenylene diamine are linked with two and 1, 3, 5-triaminobenzene with three Cr(CO)5-groups, o-phenylene diamine forms a corresponding compound with only one Cr(CO)5-group. Unlike ethylene diamine or cyclohexane diamine(1,2) o-phenylene diamine does not give a tetracarbonyl chromium(0) compound.
    Notes: Bei der Umsetzung von Alkali-pentacarbonyl-chromaten(-II) mit wäßrigen Lösungen von aromatischen Mono-, Di- und Triaminen bei gewöhnlicher Temperatur erhält man stets Pentacarbonyl-amin-chrom(0)-verbindungen, die sich als echte Substitutions-produkte des Cr(CO)6 erweisen. Während m- und p-Phenylendiamin zwei und 1,3,5-Triaminobenzol drei Cr(CO)5-Gruppen zu binden vermögen, erhält man im Falle des o-Phenylendiamins eine entsprechende Verbindung mit nur einer Cr(CO)5-Gruppe. Insbesondere entsteht bei letzterem - im Gegensatz zum Äthylendiamin - keine Tetracarbonyl-chrom(0)-verbindung. Eine solche bildet sich hingegen, wenn man an Stelle des o-Phenylendiamins das hydrierte o-Phenylendiamin, also Cyclohexandiamin(1,2), zur Reaktion bringt.

    Description / Table of Contents: The First Oligo-Oxo-Aluminate: Na14[Al4O13]Colourless single crystals of Na14[Al4O13] are formed by reaction of Na2O and Al2O3 in a closed Ni-cylinder at 980 K. The compound is very sensitive against moisture. Na14[Al4O13] crystalizes in the monoclinic space group P21/c with 2 formula units (a = 599.7, b = 2704.0, c = 596.9 pm, β = 120.1°). The characteristic feature of the structure, the anion [Al4O13]14-, is built of four AlO4-tetrahedra, sharing vertices. The connection of these groups by the counter-cations is discussed.
    Notes: Farblose Einkristalle von Na14[Al4O13] bilden sich bei der Reaktion von Na2O mit Al2O3 bei 780 K im geschlossenen Ni-Bömbchen. Die Substanz ist stark feuchtigkeitsempfindlich. Na14[Al4O13] kristallisiert in der monoklinen Raumgruppe P21/c mit 2 Formeleinheiten (a = 599,7, b = 2704,0, c = 596,9 pm, β = 120,1°). Die charakteristische Baugruppe der Struktur ist das erstmals erhaltene Anion [Al4O13]14-, welches von vier über Ecken verknüpften AlO4-Tetraedern gebildet wird. Die Verknüpfung dieser Gruppen durch die Gegenkationen wird besprochen.
