    Description / Table of Contents: Zusammenfassung Bei Achalasiepatienten zeigen manometrische Untersuchungen nach Kardiomyotomie und Dehnung eine signifikante Reduktion des pathologisch erhöhten Sphincter- und Speiseröhren-innendruckes. Nach beiden Behandlungsmethoden können Refluxoesophagitiden auftreten. Im Tierexperiment wird deshalb der Einfluß refluxverhindernder Operationen (Funduskissenoperation, Fundoplikatio) auf den myotomierten Sphincter manometrisch untersucht. Die Funduskissenoperation bewirkt keine Sphincterdruckerhöhung, nach zusätzlicher Fundoplikatio steigt der Sphincterdruck signifikant an. Die Funduskissenoperation wird deshalb bei der Achalasie empfohlen.
    Notes: Summary After esophagomyotomy and dilatation, manometric investigation in patients with achalasia shows a marked and significant reduction of pathologically elevated lower esophageal sphincter pressure (LESP). Reflux esophagitis is a possible complication after both methods of treatment. Therefore, in foxhounds, the influence of reflux-preventing operations (fundoplication, fundic patch op.) on the sphincter after myotomy has been studied manometrically. The fundic patch operation causes no increased LESP, whereas after additional fundoplication, a significantly elevated LESP could be seen. The fundic patch operation therefore is recommended for the operative treatment of achalasia.

    Description / Table of Contents: Summary Brattleboro rats homozygous for hypothalamic hereditary diabetes insipidus (DI rats) were used to investigate the following questions: a) Do exogenous and endogenous angiotensin II (AII) have an antidiuretic effect in diabetes insipidus? b) Does AII mediate the antidiuresis induced by furosemide? The following results were obtained: 1. AII (5 mg/kg s.c. in oil) and furosemide (50 mg/kg i.p.) decreased urine flow and increased urinary sodium excretion. Furosemide led to a two-fold increase of AII plasma concentrations and a decrease of plasma sodium levels. 2. SQ 14 225 (2×2.5 mg/kg p.o.), an angiotensin I-converting enzyme inhibitor, led to an increase of urine flow and to a slightly elevated urinary sodium excretion. 3. When the formation of AII was blocked by SQ 14 225 (2×2.5 mg/kg p.o.), AII plasma concentrations were 2.5-fold decreased, but furosemide still reduced urine flow. We conclude that plasma AII might have an antidiuretic action in DI rats. However, AII does not mediate the antidiuresis induced by furosemide.
    Notes: Zusammenfassung Bei Brattleboro-Ratten mit hereditärem hypothalamischen Diabetes insipidus (DI Ratten) wurden folgende Fragen untersucht: a) Wirken exogenes and endogenes Angiotensin II (AII) antidiuretisch bei Diabetes insipidus? b) Vermittelt AII den antidiuretischen Effekt von Furosemid? Ergebnisse: 1. AII (5 mg/kg s.c. in Ö1) und Furosemid (50 mg/kg i.p.) verminderten die Urin- und erhöhten die renale Natriumausscheidung. Furosemid führte zu einem zweifachen Anstieg der AII Plasma Konzentration und zur Verminderung der Plasma-Natrium Konzentration. 2. SQ 14 225 (2×2,5 mg/kg p.o.), ein Hemmer des Angiotensin I Converting Enzym, führte zu einer Zunahme der Urin- und der renalen Natriumausscheidung. 3. Auch wenn die Bildung von AII mit SQ 14 225 (2×2,5 mg/kg p.o.) blockiert wurde, reduzierte Furosemid die Urinausscheidung, obwohl die AII Plasma Konzentration 2,5fach vermindert war. Wir schließen daraus, daß Plasma AII bei DI Ratten antidiuretisch wirken kann. Allerdings vermittelt AII nicht den antidiuretischen Effekt von Furosemid.

    Notes: In zahlreichen aprotischen, organische Kationen enthaltenden Lösungsmitteln läßt sich molekularer Sauerstoff elektrochemisch zum O2--Ion reduzieren. Die Kinetik der Reaktion hängt entscheidend vom Elektrodenmaterial ab. Lösungen mit O2--Ionen bzw. Ionen, die eine O2--Gruppe enthalten, haben basische, nukleophile und Redox-Eigenschaften. Die Autoxidation aromatischer Kohlenwasserstoffe wird durch O2--Ionen katalytisch beschleunigt; eine Oxidation ist auch in Abwesenheit von molekularem Sauerstoff möglich. Die nukleophile Substitution von Halogen-Atomen oder ähnlichen Gruppen führt in guter Ausbeute über Hydroperoxid-Radikale zu organischen Peroxiden. Einige weitere nukleophile und Redox-Reaktionen des O2--Ions werden kurz erläutert.
