    Description / Table of Contents: Zusammenfassung Die quantitative und qualitative Analysen der sauren Glykosaminoglykane in den Grundsubstanzen der lateralen Wand des häutigen Labyrinths, der Nieren, des Gehirns und der Leber von Meerschweinchen wurden mittels der elektrophoretischen Mikroanalysenmethode ausgeführt. Die laterale Wand der Schnecke enthielt die höchste Menge (0,46±0,08% pro Trockengewicht) der sauren Glykosaminoglykane, die aus Chondroitinsulfat-B (75%), Chondroitinsulfat-A (12%) und Hyaluronsäure (13%) bestanden. Jedoch schwankt die Zusammensetzung der Glykosaminoglykane im Innenohr, ebenso wie in den anderen Organen, erheblich. Eine mögliche Bedeutung der Glykosaminoglykane für die Funktion des Hörorgans wurde diskutiert.
    Notes: Summary Acidic glycosaminoglycans in the ground substance of the membranous cochlear lateral wall, kidney, brain and liver of the guinea pigs were quantitatively and qualitatively analyzed, using electrophoretic microanalysis. The lateral wall of the cochlea showed highest content (0.46±0.08%/D.W.) of acidic glycosmainoglycans, which were chondroitin sulfate-B (75%), chondroitin sulfate-A (12%) and hyaluronic acid (13%). However, the pattern of these acidic glycosaminoglycans in the inner ear differed from the other organs. A possible role of acidic glycosaminoglycans in the inner ear was discussed.

    Description / Table of Contents: Diazoalkane Complexes of Nickel(0) and Palladium(0) and Their Relevance to Carbenoid ReactionsA series of diazoalkane complexes with the composition ML2(diazoalkane) [M = Ni, Pd; L = tBuNC, PPh3; diazoalkane = 9-diazofluorene or diphenyldiazomethane] have been prepared and characterized, and their thermolysis and displacement reactions investigated. The nickel complexes catalyse a carbenoid reaction which leads to ketenimine formation. A carbene complex having the formula Pd(PPh3)2(C13H8) was obtained by low temperature thermolysis of Pd(PPh3)2(9-diazofluorene).
    Notes: Eine Reihe von Diazoalkankomplexen mit der Zusammensetzung ML2(Diazoalkan) [M = Ni, Pd; L = tBuNC, PPh3; Diazoalkan = 9-Diazofluoren oder Diphenyldiazomethan] wurde dargestellt und charakterisiert; ihre Thermolyse- sowie Verdrängungsreaktionen wurden untersucht. Die Nickelkomplexe katalysieren eine Carbenoidreaktion, die zur Keteniminbildung führt. Tieftemperaturthermolyse von Pd(PPh3)2(9-Diazofluoren) lieferte einen Carbenkomplex der Zusammensetzung Pd(PPh3)2(C13H8).
