    Description / Table of Contents: Zusammenfassung Durch Unterbindung der Vena cava caudalis bei trächtigen Kaninchen konnte in jedem Falle ein intrauterines Absterben der Feten bewirkt werden. Durch Veränderung des zeitlichen Abstandes zur Explorativlaparotomie mit makroskopischer und mikroskopischer Untersuchung der Feten und Placenten konnten typische Veränderungen, die in direkter Relation zur Dauer der venösen Rückflußbehinderung standen, nachgewiesen werden. In einem Zusatzversuch wurde gezeigt, daß die Feten nach der Unterbindung der Vena cava innerhalb der ersten 10 min absterben, ohne daß zu diesem Zeitpunkt bereits wesentliche mikroskopisch faßbare Placentaveränderungen bestehen. Ursächlich wird für diesen Sachverhalt in Übereinstimmung mit den spärlichen bereits vorliegenden Angaben aus der Literatur ein kurzzeitiger, steiler Druckanstieg im venösen Schenkel der utero-placentaren Zirkulation mit konsekutiver Hypoxie angenommen. Die histologisch nachweisbaren Placentaveränderungen sind sicher sekundärer Natur. Es kommt zur hämorrhagischen Infarzierung der Placenta und zur Ausbildung regressiver Veränderungen in diesem Organ. Vergleiche zwischen den vorgelegten tierexperimentellen Untersuchungsergebnissen und unseren Vorstellungen über die Pathophysiologie des Vena-cava-inferior-Syndroms und seine Auswirkungen auf die utero-placentare Zirkulation und den Zustand des Feten drängen sich auf.
    Notes: Summary By ligature of the vena-cava-caudalis in pregnant rabbits it has always been possible to cause an intra-uterin death of the fetus in all cases. In changing the temporal distance between ligature and exploration by the way of laparotomy the authors could show typical alterations at the fetuses and the placenta with direct relation to the obstruction of the venous backflow by macroscopical and histological investigations. It was demostrated that the fetuses in about 10 minutes after cliping the vena-cava-inferior died. It was impossible to find pathological changes at the fetus or the placenta after this time. The authors assume, that the fetuses died by hypoxemia as the result of the acute increase of the venous pressure in the utero-placental circulation. Histological findings in the placenta appear later. There will be haemorrhagic infarction and regressive alterations in this organ. It is taken a comparision between the findings of this studies in rabbits and the effect of the supine hypotensive syndrom to the fetus.

    Description / Table of Contents: Summary Methods are described for the exchange separation of gold from the metal ions that are usually well extractible with TBP, and that have been developed on the basis of the behavior of this element on the anion exchanger Dowex 1, X8 in the chloride form in the solvent system containing TBP. It was shown that the most favorable separating effects were created through the fact that gold, obviously as the result of the production of a stable well solvated TBP-complex, remains dissolved in the solvent phase and is not adsorbed on the anion exchanger, whereas the interfering elements are firmly held there. In particular separations were accomplished between gold on one hand and Cu, Zn, Co, Hg, U and the platinum metals on the other, all of which as a consequence of the formation of stable chlorocomplexes, are strongly adsorbed on the anion exchanger and because of the formation of less stable TBP-complexes and hence are quantitatively separated from Cu(II), Co(II), Hg(II), Uo2(II) and Pd(II). In order to accomplish the separation from those elements, which like gold are not adsorbed on the ion exchanger, a reducing cellulose was prepared with which gold is specifically reducible to metal, and deposited in the fiber, and after destruction of the organic substance and solution in aqua regia it may be determined complexometrically.
    Notes: Zusammenfassung Methoden zur Anionenaustauschtrennung des Goldes von anderen, meist mit TBP gut extrahierbaren Metallionen werden beschrieben, die auf Grund des Verhaltens dieser Elemente am Anionenaustauscher Dowex 1, X8 in der Chloridform in TBP-haltigen Lösungsmittelsystemen entwickelt wurden. Dabei konnte gezeigt werden, daß die günstigen Trenneffekte dadurch Zustandekommen, daß Gold offenbar infolge der Bildung eines beständigen, in der Lösungsmittelphase gut solvatisierten TBP-Komplexes gelöst bleibt und am Anionenaustauscher nicht adsorbiert wird, während die störenden Elemente daran stark festgehalten werden. Insbesondere wurden Trennungen zwischen Gold einerseits, Cu, Co, Zn, Hg, U und den Platinmetallen andererseits, untersucht, die alle infolge der Ausbildung beständiger Chlorokomplexe, hingegen weniger beständiger TBP-Komplexe am Anionenaustauscher stark adsorbiert werden. Gold läßt sich von Cu(II), Co(II), Hg(II), UO2(II) und Pd(II) quantitativ trennen. Um es auch von jenen Elementen trennen zu können, die gleich ihm am Ionenaustauscher nicht adsorbiert werden, wurde eine reduzierende Zellulose hergestellt, mit der Gold spezifisch zu Metall reduzierbar ist, in der Faser abgeschieden wird und nach Zerstörung der organischen Substanz und Auflösen in Königswasser komplexometrisch bestimmt werden kann.
