    Description / Table of Contents: Zusammenfassung Nach dem Verfahren der Verteilungsanalyse von Ventilation $$\dot V_A $$ , Perfusion, $$\dot Q$$ und O2-DiffusionskapazitätD L in der menschlichen Lunge werden 14 lungengesunde Jugendliche, 6 ältere Personen mit chronischer Emphysembron-chitis und 10 lungengesunde Schwangere untersucht. Das Verfahren liefert neben den Verteilungskurven für die Funktionsgrößen $$\dot V_A ,\dot Q$$ undD L die folgenden über die gesamte Lunge gemittelten Werte: das Ventilations-Perfusions-Verhältnis das O2-Diffusionskapazitäts-Perfusions-Verhältnis, die alveolären, die endcapillären und die arteriellen O2-bzw. CO2-Drucke, die Anteile der alveolär-arteriellen Druckdifferenzen sowie die Absolutwerte für die alveoläre Ventilation, die Lungendurchblutung, die O2-Diffusionskapazität und den extrapulmonalen Kurzschlußblut-Anteil. Die wesentlichen Ergebnisse der Untersuchung sind in der folgenden Tabelle, zusammengefaßt. Die Gründe für die differierenden Funktionswerte in den einzelnen Personen-gruppen werden diskutiert.
    Notes: Summary 14 adolescents with healthy lungs, 6 elderly people with chronic emphysema bronchitis, and 10 pregnant women with healthy lungs, were examined by the method of distribution analysis of ventilation, $$\dot V_A $$ , perfusion, $$\dot Q$$ , and O2 diffusing capacity,D L. Besides the distribution curves for the function values, $$\dot V_A $$ , $$\dot Q$$ , andD L, this method also furnishes the following average values, which were obtained throughout the lung: the ventilation-perfusion ratio, the O2 diffusing capacity-perfusion ratio, the alveolar, endcapillary, and arterial O2 and CO2 pressures, the components of the alveolar-arterial pressure differences, as well as the absolute values for the alveolar ventilation, lung perfusion, O2 diffusing capacity and the extrapulmonary shunt component. The essential test results are summarized in the following table: The reasons for the varying functional results, found in the individual groups, are discussed.

    Description / Table of Contents: A lot of nickel and copper complexes of Schiff bases were prepared and investigated for their solubility behaviour. Amine components and aldehyde components used see „Inhaltsübersicht„.As far as investigated, the solubility of those compounds containing 4. and 5. is poor in most solvents, but it is better in pyridine. N.N′-pentamethylene-bis(salicylideneiminato)-nickel(II) is trimeric in pyridine. The copper and nickel salts containing the bulky amines 7.,8. and 9. are oligomeric (n = 2 to n = 5) in bromoform and pyridine. The salts containing 11. are monomeric in pyridine. With Stuart models it is possible to construct dimers containing 7. and 9. as amine components having square planar configuration around the metal atom. With strongly distorted tetrahedral configuration it is possible to obtain monomers. With 17., completely insoluble high polymeric compounds were obtained, whereas with 12. oligomers are found.
    Notes: Es wurde eine große Anzahl von Ni- und Cu-Komplexen mit Schiffschen Basen dargestellt und auf ihr Lösungsverhalten untersucht. Als Aminkomponenten dienten: 1. bis 5. H2N · (CH2)xNH2 mit x = 2 bis 6, 6. 1,8-Diaminonaphthalin, 7. 1-Amino-3-aminomethyl-3,5,5-trimethylcyclohexan, 8. 1,4-Bis-(aminomethyl)-cyclohexan, 9. 1,6-Diamino-2,4,4-trimethylhexan, 10. 1,5-Diamino-diäthylen-amin, 11. 1,7-Diamino-dipropylen-amin und 12. 4,4′-Diamino-diphenyl-methan, -amin, -sulfid und -äther. Als Aldehydkomponenten wurden verwendet: 13. Salicylaldehyd, 14. 5-Brom-Salicylaldehyd, 15. β-Resorcylaldehyd, 16. 2-Hydroxy-naphthaldehyd und 17. 5,5′-Methylen-bis-(Salicylaldehyd).Soweit untersucht, ist die Löslichkeit der Verbindungen mit 4. und 5. meist schlecht, in Pyridin aber besser. Bis-(Salicylaldehyd)-Ni(II)-1,5-diimino-pentan ist in Pyridin trimer. Die Cu- und Ni-Salze mit den sperrigen Diaminen 7., 8. und 9. sind in Bromoform und Pyridin oligomer (2 bis 5), mit 11. wird in Pyridin das Monomere gefunden. Mit Stuart-Kalotten lassen sich Dimere mit 7. und 9. als Aminkomponente bei planquadratischer Konfiguration um das Metallatom aufbauen, bei stark tetraederförmig verzerrter Konfiguration sind sogar bei 7. Monomere möglich. 17. führt stets zu völlig unlöslichen hochpolymeren Verbindungen, wohingegen 12. häufig zu oligomer löslichen Komplexen führt.
