    Description / Table of Contents: Contents The principle of operation of permanent magnet stepping motors with small step angles is explained by employing the theory of rotating field harmonics. A general correlation for suitable numbers of stator and rotor slots is developed making it possible to calculate the step angle and the ratio of speed to input frequency as well as to estimate the inductances and iron losses. Based on these results suggestions for the design of drive circuits are given. It is proposed to indicate the described type of stepping motor as „harmonic stepper”.
    Notes: Übersicht Die Wirkungsweise der meist angewandten Bauart von permanentmagnetischen Schrittmotoren mit kleinem Schrittwinkel wird mit der Theorie der Oberwellendrehfelder erklärt. Eine allgemeine Beziehung für die möglichen Nutzahlen von Stator und Rotor wird entwickelt. Mit dieser lassen sich der Schrittwinkel und das Verhältnis von Drehzahl zu Speisefrequenz berechnen sowie die Induktivitäten und Einsenverluste abschätzen. Darauf aufbauend werden Hinweise für die Auslegung der Ansteuerung gegeben. Für die beschriebene Schrittmotorenbauart wird die Bezeichnung “Oberwellen-Schrittmotor” vorgeschlagen.

    Notes: Summary The distribution of fiber branching in the proximal intramuscular motor nerves of the gracilis and gastrocnemius muscles of the rat was studied in whole-mount preparations of teased nerves. Branchings of nerve fibers were clustered at fascicular divisions. Such concurrence of fascicular and fiber branchings determines the dispersion of the single muscle fibers belonging to a motor unit. The distribution of fiber branching reveals the wiring pattern of muscle fibers. These patterns differed for the gracilis and gastrocnemtus muscles in correspondence with their functional organization.

    Notes: Summary Unilateral hydrocephalus due to occlusion of one foramen of Monro was found incidentally at necropsy in a 52-year-old man. There was no evidence of a postinflammatory or neoplastic origin of the occlusion. Backward tilting of the diencephalon, asymmetric insertion of the septum pellucidum, lateral tilting of the fornices, and deformation of the hippocampal formation indicated an early developmental origin of the lesion.

    Notes: Zusammenfassung 1. Die ursächlichen Möglichkeiten der Jodsalzschädigungen bei der menschlichen Prophylaxe werden besprochen, und es wird aus bekannten Beobachtungen über den natürlichen Jodumlauf die Bindungsart des Jods bei seiner prophylaktischen Anwendung als mitbestimmend für die Schädigungen angesehen. 2. Die neuerdings vorgeschlagene Vollsalzverabreichung an Milchtiere zur Behebung der Jodschäden wird bezüglich der sich dabei ergebenden Jodbindungsform experimentell untersucht, und es werden diesen Versuchen an Milchziegen gleichzeitig Fütterungen mit biologischem und synthetischem Jodeiweiß vergleichend gegenübergestellt. 3. Zur Beurteilung der Jodbindungsform wird der Gesamtjodgehalt der Milch sowie das prozentuale Bindungsverhältnis des Jods an Eiweiß festgestellt. 4. Bei Jodkaliverabreichung an Milchtiere wurde gefunden, daß das Milchjod nur zur etwa 30% an Eiweiß gebunden ist. 5. Die Verfütterung von synthetischem Jodeiweiß, Jodtropon, bewirkte im Vergleich zu Jodkalium eine Erhöhung des organisch gebundenen Jodanteils in der Milch auf etwa 75%. 6. Biologische Jodgaben in Form von Pflanzenjod zeigten eine noch weitergehendere Assimilation, so daß ungefähr 85% des mit der Milch sezernierten Jods als Eiweißjod erschienen. 7. Die Ausscheidungsformen des Jods in der Milch nach Pflanzen- und Jodtroponbelastung deuten auf die direkte Resorption und den unmittelbaren Transport jodierter Aminosäuren im Tierkörper hin.

    Notes: Abstract The macrophage derived cytokines interleukin-1 beta (IL-1β), and tumor necrosis factor alpha (TNFα), and the T-cell derived cytokine interferon gamma (IFNγ) have been implicated to play an important role in early attack on islet cells during human islet transplantation (ITx). Therefore, the aim of this study was to investigate the influence of the current immunosuppressive induction therapy in clinical islet transplantation on mRNA expression of these cytokines in blood cells, compared to lipopolysaccharide (LPS) induced cytokine release in vitro and to plasma levels. The cytokine release correlated to lymphocyte counts and significantly decreased after ATG, and partially recovered 2 weeks after ITx. Unexpectedly, there was no correlation between mRNA expression for IL-1β in total blood and the number of lymphocytes and monocytes remaining after anti thymocyte globulin (ATG)-therapy. Even when the blood was nearly totally depleted from mononuclear cells, high amounts of IL-1β mRNA could be detected. However, IL-1β secretion could not be stimulated in vitro. Our results show that application of ATG during ITx might contribute to graft survival during the early posttransplant period by suppression of the synthesis of monocyte derived cytokines IL-1β and TNFα.

    Notes: Abstract Endotoxin-induced early inflammatory reactions may inhibit the function and survival of isolated cells or cell aggregates after transplantation. By the chromogenic Limulus amebocyte lysate assay we found rather high but variable endotoxin concentrations in the chemicals used for islet isolation, i.e. collagenase and Ficoll. Liberase, a special collagenase preparation from Boehringer, was nearly endotoxin-free. Correlating to the endotoxin content, collagenase and Ficoll had the capacity to induce interleukin-1β release from human peripheral blood mononuclear cells. Because collagenase and density gradient media are needed in most cell isolation procedures from solid organs, each lot of these chemicals should be tested for endotoxin contamination. In pancreatic islet transplantation, the use of endotoxin-free chemicals may diminish early local inflammatory reactions at the graft site and thereby reduce the number of islets needed for successful islet transplantation.
