    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: Preparation, Structures, and Properties of SmBeF4 and SrBeF4 - Unusual Variants of the Baryt Type StructureSmBeF4 has been obtained as orange-yellow crystals and SrBeF4 as colourless crystals while heating mixtures of SmF3, Sm-powder, BeF2 (2 : 1 : 3) and SrF2 and BeF2 (1 : 1), respectively, under Ar after 7-10 d at about 700°C. SmBeF4 crystallizes in Pna21 (No. 33) with a = 846.1(5), b = 676.9(5), c = 524.1(4) pm and SrBeF4 in P21/n (Nr. 14) with a = 529.5(5), b = 830.9(2), c = 678.8(4) pm and β = 90.0°.The structures of SmBeF4 and the room temperature modification of SrBeF4 are related to the baryt type structure. The differences to the structure BaSO4 are mutual rotations of the BeF4 tetrahedra and their shift with respect to the Sm and Sr framework, respectively. According to the refinement of the structure of SmBeF4 at -174°C these effects are enhanced at low temperatures. SmBeF4 exhibits sharp luminescence lines at around 690nm. Measurements of the magnetic susceptibility show the temperature dependence typically found for Sm2+. The Madelung parts of the lattice energy for SmBeF4 und SrBeF4 have been calculated and discussed.
    Notes: Orangegelbe Kristalle von SmBeF4 und farblose Kristalle von SrBeF4 wurden durch Erhitzen entsprechender Gemenge von SmF3, Sm-Pulver, BeF2 (2 : 1 : 3) bzw. SrF2 und BeF2 (1 : 1) unter Ar nach 7-10 d bei ca. 700°C erhalten. SmBeF4 kristallisiert in Pna21 (Nr. 33) mit a = 846,1(5), b = 676,9(5), c = 524,1(4) pm und SrBeF4 in P21/n (Nr. 14) mit a = 529,5(5), b = 830,9(2), c = 678,8(4) pm und β = 90,0°.Die Strukturen von SmBeF4 und der Raumtemperaturmodifikation von SrBeF4 sind mit dem Baryttyp verwandt. Die Unterschiede zur Barytstruktur bestehen in gegenseitigen Verdrehungen der BeF4-Tetraeder und deren Verschiebung gegenüber dem Sm- bzw. Sr-Teilgerüst. Die Bestimmung der Tieftemperaturstruktur von SmBeF4 (-174°C) zeigt eine Verstärkung die ser Effekte. SmBeF4 zeigt die für Sm2+ charakteristischen intensiven Lumineszenzbanden bei etwa 690 nm sowie eine für Sm2+ typische Temperaturabhängigkeit der magnetischen Suszeptibilität. Die Madelunganteile der Gitterenergie für SmBeF4 und SrBeF4 wurden berechnet und diskutiert.
