    Notes: Background Treatment of scleroderma (systemic sclerosis. SSc) patients (stages I-III) with intravenous (i.v.) calcitonin for 10 days (100 IU/day, Karil®, Sandoz AG, Germany) 3 times/year leads to subjective and objective improvement of microcirculatory parameters determined by Laser-Doppler fluxmetry and cutaneous pO2 (pcuO2) measurement. Aim As previously suggested some rheologic effects of calcitonin might be mediated by vasoactive metabolites of the arachidonic acid metabolism. Alterations of eicosanoid plasma levels were determined in 15 SSc patients during i.v. calcitonin therapy. Methods Peripheral blood was obtained on the 1st and 9th days of therapy during a 2 h intravenous calcitonin administration. Samples were taken after 45, 90, 135 and 160 min as well as 1, 5 and 19 days after therapy was stopped. Serum levels of 6-keto-prostaglandin F1α (6-keto-PGF), a stable end product of prostacyclin synthesis, prostaglandin E2 (PGE2), leukotriene B4 (LTB4), and thromboxane B2 (TXB2) were determined by enzyme- or radio-linked assays. Results In contrast to healthy controls we measured elevated 6-keto-PGF, LTB4 and PGE2 serum levels in SSc patients before i.v. treatment, whereas TXB2 levels showed no significant differences. Calcitonin administration led to an increase of plasma 6-keto-PGF after 45 min falling back to the starting level during further treatment as well as to a longer-lasting increase of PGE2 on both the 1st and 9th days of therapy. Calcitonin treatment decreased LTB4, but did not influence TXB2 levels significantly during intravenous administration.〈section xml:id="abs1-2"〉〈title type="main"〉ConclusionOur data suggest a compensatory mechanism of the damaged vascular system with respect to the PGI2 (prostacyclin) and PGE2 formation in SSc patients measured by a constant elevation of these vasodilatory metabolites. LTB 4 may be involved in the microvascular damage in SSc. Calcitonin administration leads to a short-lasting elevation of 6-keto-PGF1α and an increase of PGE2 combined with a reduction of LTB4 resulting in longer-lasting beneficial effects on microcirculatory functions in diseased skin. Since non-steroidal anti-in-flammatory agents had no influence on long-term vasoactive effects, improvement of microcirculatory properties by calcitonin may be additionally mediated by smooth muscle relaxation of arterioles.

    Description / Table of Contents: Zusammenfassung In dieser Arbeit behandelt der Verfasser neue Ergebnisse seiner Untersuchungen über ionosphärische Ausbreitung in Australien von 1952 bis 1957. Auf eine Betrachtung über die Signalschwächung folgt eine Diskussion über die Ausbreitungswege nach Nordamerika und Westeuropa. Die Folgerungen stimmen mit den früheren Veröffentlichungen des Verfassers auf diesem Gebiet überein.
    Abstract: Résumé L'auteur expose les nouveaux résultats de ses recherches sur la propagation ionosphérique en Australie de 1952 à 1957; il considère l'affaiblissement de la propagation des signaux et les chemins suivis par les ondes vers l'Amérique du Nord et vers l'Europe occidentale. Ces résultats concordent avec ceux qu'il a publiés précédemment.
    Notes: Summary This paper presents new results of the author's investigations on ionospheric propagation in Australia from 1952 to 1957. Considerations on path attenuation are followed by a discussion on the propagation paths to North America and Western Europe. Conclusions are in agreement with the author's previous publications in this field.

    Description / Table of Contents: Zusammenfassung Die Arbeit beschreibt einen neuartigen Instrumentensatz für Messungen von Strahlung verschiedener Art. Der komplete Satz ist zum leicht beweglichen Betrieb bestimmt und besteht aus drei Einheiten, nämlich (A) Photozelle und optischer Teil, (B) Verstärker, und (C) Galvanometer. Nach einer eingehenden Einführung zu den vorliegenden Problemen ist jede Einheit in einzelheiten beschrieben, und entsprechende Abbildungen sind ebenfalls beigefügt. Ein weiterer Abschnitt der Arbeit behandelt Halbstandardgeräte, die für das beschriebene und ähnliche Instrumente Verwendung finden können, um kontrollierbare Messungen zu jeder Zeit zu erhalten. Abschließend werden mehrere Anwendungsmöglichkeiten erwähnt.
    Notes: Summary The paper describes a new instrument combination for the measurement of various kinds of radiation. The complete set-up is for mobile use and consists of three units, namely: (A) Phototube and Optical part, (B) Amplifier, and (C) Galvanometer. After a comprehensive introduction to the problems involved, each unit is described in detail and appropriate figures are also included. Another section of the paper covers semi-standard adaptors, useful for this instrument and similar ones, in order to allow controllable readings at all times. Finally, various applications are mentioned.

    Description / Table of Contents: Zusammenfassung Die Arbeit behandelt in Einzelheiten das Prinzip des Verfassers für eine komplette elektronische Telepyranometereinrichtung, deren Geber aus einem strahlungsempfindlichen Oszillator, einem Temperaturkompensationsoszillator und einem Sendeteil, dessen Betriebsfrequenz gleich der Zwischenfrequenz der beiden Oszillatoren ist, besteht. Da der Verfasser dieses Telepyranometer besonders für den Gebrauch als Strahlungs-Radionsonde entwicklte, kann der Geber 200 bis 1000 Meilen von der Bodenstation entfernt sein, wobei der Aktionsradius allein durch die Eigenschaften des Sendeteiles und die ionospherischen Ausbreitungsbegungen bestimmt wird. Die Bodenstation für Empfang und eigentliche Ablesung des Pyranometersignales ist ebenfalls beschreiben. Außerdem werden verschiedene Anwendungen dieses neuartigen Prinzips für Kapazitätsbolometer erwähnt im Hinblick auf eingehende Beschreibungen von auf diesem Prinzip basierten anderen Apparaturen zu einer späteren Zeit.
    Notes: Summary The paper deals, in detail, with the writer's principle of a complete electronic tele-pyranometer system whose remote unit comprises a radiation-sensitive oscillator, a temperature-compensating oscillator, and the transmitting section operating on a frequency equal to the intermediate frequency of the two. As the writer developed this pyranometer especially for airborne use as Radiation Radio Sonde, the remote unit may be as far as 200 to 1000 miles from the base station, the maximum distance being solely governed by the capability of the transmitting section and by the ionospheric propagation conditions. Comments are also made on the base station for the reception and actual reading of the pyranometer signal. In addition, various applications for this new capacitance bolometer principle are mentioned in anticipation of detailed descriptions of other apparatus based upon the principle, at a later date.
