    Description / Table of Contents: Zusammenfassung Bronchialtoilette beginnt mit Entfernung von Fremdkörpern. Über eine Spezialmaske (Groitl) können diese auch bei Kindern mit flexiblen Bronchoskopen entfernt werden. Die herkömmliche Methode der Katheterabsaugung verletzt das Bronchialepithel erheblich. Mit dem flexiblen Bronchoskop können beide Seiten des Bronchialsystems gleich gut erreicht und von Sekret gereingt werden. Die Technik ist einfach. Jeder auf der Intensivstation tätige Arzt sollte mit dem flexiblen Bronchoskop die Bronchialtoilette durchführen können. Die Erfahrung von ca. 7000 bronchoskopischen Absaugungen erklärt den Erfolg und macht das Blähen bei Atelektasen überflüssig.
    Notes: Summary Cleansing the bronchial tubes includes, first of all, removal of foreign bodies. Via a special mask (Groitl) foreign bodies can be taken out even in children. The usual method suctioning with a catheter can injure the bronchial epithelium. With the flexible bronchofiberscope both sides of the bronchial tree can be reached and cleansed of secretions. The technique is simple, and every physician in an intensive care unit should be able to handle a flexible scope to clean thebronchial tubes. In more than 7,000 cases this method has proven successful and has eliminated the necessity of using the inflating procedure in atelectases.

    Description / Table of Contents: Zusammenfassung Flexible Bronchoskope haben folgende Vorteile gegenüber den starren Geräten: in Lokalanästhesie kann der Patient ambulant untersucht werden. Weiter peripher gelegene, dadurch kleinere Tumore können histologisch gesichert werden. Gezielte Bronchographien mit Absaugung des Kontrastmittels aus der Peripherie sind möglich, kleine Bronchialeinrisse peripher können erkannt werden. Fremdkörper sind auch mit flexiblen Instrumenten leicht zu entfernen. Die postoperative Bronchialtoilette mit dem flexiblen Bronchoskop gewährleistet hohe Effektivität und geringe Verletzungsgefahr des Bronchialepithels. In Diagnostik und Therapie ist das starre durch das flexible Bronchoskop überholt.
    Notes: Summary Flexible bronchoscopes have advantages over rigid instruments. In an outpatient under local anesthesia, more peripheral, smaller tumors can be histologically proved. Bronchography can be performed purposefully with aspiration of the contrast medium. Small peripheral ruptures of the bronchial tree can be recognized. All kinds of foreign bodies can be removed by flexible instruments. Postoperative bronchial cleaning is highly effective and there is only a low risk of injuring the bronchial epithelium. For diagnosis and therapy the rigid instruments are antiquated.

    Notes: The hydrogen concentration profiles of electrochromic multilayer systems produced by evaporation have been determined by means of nuclear reaction analysis. The H content of individual oxidic materials was found to be larger than for single films, especially for SiO2. The time-dependent H uptake under various ambient conditions was investigated. Systems produced by ion plating were also profiled for hydrogen.

    Description / Table of Contents: The very complex isomerization patterns of methoxy and carbomethoxy substituted cycloalkanes (3- to 7-membered rings) have been investigated using collisional activation, metastable ion characteristics and field ionization kinetics. The extent of isomerization depends on both the ring size and the substituent. Irrespective of the electronic properties of the substituent, ring opening involves exclusively the C-1—C-2 bond whereby linear alkene radical cations are formed. In the case of OCH3- and COOCH3 substituents the position of the resulting double bond (terminal or α,β-unsaturated) is determined more by the ring size of the precursor molecules and less by the electronic properties of the substituents. Contrary to these findings alklyl substituted cycloalkanes (3- to 5-membered rings) rearrange exclusively to terminal alkene radical cations. The barrier for double bond isomerization seems to be substantially influenced by substituents.
    Notes: Unter Benutzung mehrerer Techniken, wie Stoßaktivierung, Charakteristik metastabiler Ionen und Feldionisationskinetik, wird das äußerst komplexe Isomerisierungsverhalten von methoxy- und caarbomethoxysubstituierten Cycloalkanen (drei-bis siebengliedrege Ringe) analysiert. Das Ausmaß der Isomerisierung hängt sowohl von der Ringgröße als auch vom Substituenten ab, während die Ringöffnung unabhängig von den elektronischen Eigenschaften der Substituenten immer die C-1—C-2-Bindung betrifft. Hierbei werden ausschließlich lineare Alken-Radikalkationen erzeugt. Bei OCH3- und COOCH3-Substituenten wird die Lage der resultierenden Doppelbindung terminal oder α,β-ungesättigt hauptsächlich durch die Ringgröße des Cycloalkan-Molekülions und weniger durch den Substituenten beeinfluß. Alkylsubstituierte Cycloalkane (drei- bis fünfgliedrige Ringe) lagern sich allerdings nur zu terminalen Alken-Radikalkationen um. Die Barriere der Doppelbindungswanderung scheint vom Substituenten abhängig zsu sein.

    Description / Table of Contents: Chalcogenide Glasses with Organic Components. V. The Reactivity in the Glass-forming Systems Selenium, Arsenic, Bromine, 4,4′-Bis(selenenylbromido)azobenzene and Selenium, Arsenic, Iodine, 4,4′-Bis(diiodarsa)biphenyleneSe—As—Br glasses and 4,4′-bis(selenenylbromido)azobenzene react in the solid state. In this case arsenic is an acceptor for bromine, and azobenzene groups will be linked via poly-selenide groups with the glass matrix. The reaction is proved by DTA. At elevated temperatures, the selenium-carbon bond will be replaced by a carbon-bromine link yielding 4,4′-dibromazobenzene. Solid 4,4′-bis(diiodarsa)biphenylene shows a similar reaction with Se—As—I above TG. The pyrolysis takes place at higher temperatures.
    Notes: Gläser des Systems Se—As—Br reagieren im festen Zustand mit 4,4′-Bis-(selenenylbromido)azobenzol. Dabei wirkt Arsen als Bromakzeptor, und die Azobenzolgruppen werden über Polyselenidgruppen mit der Glasmatrix verknüpft. Die Reaktion wurde differentialthermoanalytisch verfolgt. Bei höheren Temperaturen werden die Selen-Kohlenstoff-Bindungen durch Brom-Kohlenstoff-Bindungen ersetzt. 4,4′-Dibromazobenzol kann durch Sublimation isoliert werden. Festes 4,4′-Bis(dijodarsa)biphenyl reagiert in analoger Weise mit unterkühlten Selen-Arsen-Jod-Schmelzen.
