    Description / Table of Contents: Zusammenfassung Steriliaation. Hitzelabile Utensilien sind möglichst als sterilisierte Einweggeräte zu verwenden. Entlüftung nach Äthylenoxidsterilisation: PVC, unbekannte Kunststoffe: 7 Tage; Gummi: 5 Tage; Polyäthylen-, -propylen: 24 Std. -Gereinigte Geräte mit Schutzschicht (z. B. Herzschrittmacher) sind auch mit „Alhydex®” sterilisierbar. -Desinfektion: s. „IV. Liste” der DGHM-„Quats” sind unwirksam gegen gramnegative („Naß-”)Keime. Laufende biologische Kontrolle aller Maßnahmen ist notwendig. Einsatz von Krankenhaushygienikern mit Arbeitsstab zur Beratung in allen Fragen der Hospitalismus-Bekämpfung wird empfohlen.
    Notes: Summary Sterilization: thermolabile instruments should be used as sterile disposable articles. Articles should be ventilated for the following periods after sterilization with ethylenoxide: PVC and unknown synthetic materials: 7 days, rubber articles: 5 days, polyethylene/ polypropylene: 24 hrs. Apparatus with a protective layer can also be sterilized with Alhydex® after cleaning. Disinfection: see “IV. Liste der DGHM”. “Quats” are not effective against gram-negative bacteria growing on wet surroundings. Continuous biological monitoring of all measures is necessary. The employment of hospital hygienists to advise on all problems of hospital infection is recommended.

    Description / Table of Contents: Zusammenfassung Tetrachlorkohlenstoff (3 μl/g i.p.) führt bei Mäusen nach 6 und in noch stärkerem Maße nach 12 Std zu einer Vergrößerung der Nieren sowie einer Zunahme des renalen Wasser- und Triglyceridgehalts. Dem Anstieg des Fettgehalts der Nieren geht eine Vermehrung der unveresterten Fettsäuren im Serum parallel. Sowohl der Anstieg der unveresterten Fettsäuren im Serum als auch die Zunahme der Triglyceride in der Niere lassen sich durchβ-Pyridylcarbinol (500 μg/g i.m. alle 6 Std) verhindern. Daraus wird geschlossen, daß die durch Tetrachlorkohlenstoff verursachte Zunahme des Nierenfetts das Resultat einer gesteigerten Lipolyse sowie einer vermehrten Aufnahme von Fettsäuren in die Niere mit nachfolgender Veresterung der Fettsäuren zu Triglyceriden darstellt. Auf die unter Tetrachlorkohlenstoff zu beobachtende Vergrößerung der Nieren, die Zunahme des renalen Wassergehalts und die damit im Zusammenhang stehenden morphologischen Veränderungen im Bereich des Tubulus contortus (Trübe Schwellung, Einengung des Tubuluslumens, vermehrtes Auftreten von Eiweiß in den Tubuli) hatteβ-Pyridylcarbinol keinen Einfluß.
    Notes: Abstract In mice carbon tetrachloride (3 μ.l/g i.p.) causes an increase in kidney weight, water and triglyceride content after 6h, which is even more pronounced after 12 h. The increase in the renal fat content is closely paralleled by an increase in the serum non-esterified fatty acids. Since both the elevation of the non-esterified fatty acid level in the serum and the increase in the renal triglyceride content can be prevented by the antilipolytic drug ß-pyridylcarbinol (500 μg/g i.m. every 6 h) it is assumed that the accumulation of fat in the kidneys produced by carbon tetrachloride is the result of enhanced lipolysis and uptake of fatty acids into the kidneys, with subsequent esterification of the fatty acids to triglycerides.β-pyridylcarbinol had no influence on the increase in the weight and water content of the kidneys and the morphological changes (albuminous swelling, constriction of the lumen of the tubuli, increased protein permeability) produced in the tubule system by carbon tetrachloride.

    Notes: Abstract Any conformal or projective structure on a manifold ℳ defines a natural boundary ∂ℳ. For Minkowski space these coincide with null infinity as defined by Penrose and projective infinity as defined by Eardley and Sachs, respectively.

    Notes: Abstract In [1] it was shown how to attach a boundary to any space-time. In the present paper a boundary is constructed for any bundle associated with the frame bundle of a space time. In such a way limits of tensor fields at boundary points of a space-time are defined. Using this we show that the Lorentz metric has always a unique continuous extension to theb-boundary of the space-time.

    Notes: Abstract It is shown that a torsion free linear connection is determined by a metric of given signature if and only if its holonomy group is a subgroup of the orthogonal group corresponding to the signature.

    Description / Table of Contents: Zusammenfassung Die Acylierung von 2-Amino-3.3-diphenyl-5-methyl-1-pyrrolin (1) und 2-Amino-3.3-diphenyl-1-pyrrolin (2) erfolgt in den hier untersuchten Fällen am N-2-(exo)-Stickstoff. Die Umsetzung der cyclischen Amidine1 und2 mit BrCN gibt jedoch neben den N-2-(exo)-auch die N-1-(endo)-Cyanamidine. Diese werden in die entsprechenden Carbamoyl- und Thiocarbamoylamidine umgewandelt.
    Notes: Abstract Acylations of 2-amino-3.3-diphenyl-5-methyl-1-pyrroline (1) and 2-amino-3.3-diphenyl-1-pyrroline (2) occur at the N-2-(exo)-nitrogen. However, reaction of1 and2 with BrCN yields not only the N-2-(exo)-cyanoamidines but also the N-1-(endo)-isomers. Either is converted into the corresponding carbamoyl and thiocarbamoyl amidines.
