    Notes: Summary With three phosphohydrolases, i. e. alkaline phosphatase (Na+K+), ATPase and (Mg++) ATPase, a segmentation of the proximal tubule and a marked difference between the short (superficial) and long (Juxtamedullary) nephron is revealed by quantitative histochemistry. With the exception of the superficial nephron of the male rat, alkaline phosphatase activity increases along the proximal tubule independent of sex. (Na+K+) ATPase and (Mg++) ATPase show in both types of nephrons a decrease of activity along the proximal tubule. The juxtamedullary nephron is more active than the superficial. Parallelism of the site of avtivity for alkaline phosphatase and the location of reabsorption of phosphate ions is discussed. Morphological and physiological data from the literature are brought into connexion with the enzymatic changes of a (Na+K+) ATPase activity decrease.

    Notes: Zusammenfassung Histochemische und biochemische Untersuchungen des Verhaltens von Aminopeptidasen nach Furosemidgabe zeigen einen Abfall bzw. Anstieg der Enzymaktivitäten in Nierenschnitten und im Urin von männlichen Wistar-Ratten. Die Resultate weisen auf eine direkte, Furosemid-induzierte reversible Epithelschädigung im proximalen Tubulus hin. Unter gleichen Bedingungen sind entsprechende Befunde bei weiblichen Wistar-Ratten nicht zu erheben.

    Notes: Summary In 17 male Wistar rats in antidiuresis 10 different nephron segments and arteries are identified with the aid of Lowry's technique, dissected and total-and (Mg++)-adenosintriphosphatase (=ATPase) determined. (Na+K+)-activated ATPase in the distal tubule is four to five times (max. eight times) more active than in the proximal segment. This difference of activity may speak for a high pump mechanism mediated by the way of a (Na+K+)-activated enzyme system in the distal nephron and for a partially passive reabsorption of sodium from the proximal convolution.

    Description / Table of Contents: Abstract In the photolysis of gaseous benzoyl bromide, the orange-red benzoyl radical, which is stable at 70° Kelvin, was frozen out. Stability is not enhanced by a methoxyl group or chlorine atom in the para position. Color, ESR spectra and thermal stability were indentical with that of the benzoyl radical from the photolysis of benzaldehyde. Benzil and benzophenone were identified after recombination of the benzoyl radical.
    Notes: Zusammenfassung Bei der Photolyse von Benzoylbromid im Gaszustand wurde das orange-rote Benzoyl-Radikal ausgefroren, das bei 70° K beständig ist. Methoxylgruppe und Chloratom in p-Stellung wirken nicht stabilisierend. Farbe, ESR-Spektrum und Thermostabilität sind identisch mit denen des Benzoyl-Radikals aus der Bestrahlung des Benzaldehyds. Nach der Rekombination des Benzoyl-Radikals wurden Benzil und Benzophenon identifiziert.

    Notes: Abstract A 10-stage digital light beam deflector is described using Kerr cell polarisation switches and calcite birefringent prisms. Optimum design criteria are derived with respect to resolution and drive voltage. The final device had an overall transmission of 91% and could be switched from one direction to another in 0.2μsec.
