    Description / Table of Contents: Abstract Ionenes with the formula {[NMe2(CH2)5NMe2(CH2) n ]2I}p (where Me=methyl group;n=3, 4, 5; andp the degree of polymerization) have been prepared. Their NMR and IR spectra are shown and discussed. When these compounds are associated with silver iodide they give conducting compounds which obey the Arrhenius law. The highest conductivity of the AgI−N-pentylene, N′-alkylene, N, N, N′, N′-tetramethyl diammonium polyiodide system, at 25°C, is 0.01 Ω cm−1, corresponding to a compound containing 80% of AgI equivalent. This study has been carried out with the purpose of achieving solid generators.
    Notes: Résumé Les ionènes de formule {[NMe2(CH2)5NMe2(CH2) n ]2I}p (avec Me=radical méthyl;n=3, 4, 5; etp le degré de polymérization) ont été préparés. Leur spectre RMN et IR est présenté et discuté. Associés à de l'iodure d'argent, ils donnent des composés conducteurs qui suivent la loi d'Arrhénius. Le système AgI-polydiiodure de N pentylène N′ propyléne tétraméthyl N, N, N′, N′ diammonium possède à 25°C une conductivité maximale de 0.01 Ω cm−1 pour une composition renfermant 80% en équivalent de AgI. Cette étude se place dans une perspective de mise au point de générateurs tout solide.

    Notes: Abstract  Despite sophisticated surgical methods only a few pediatric CNS tumors can be controlled by operation alone. Therefore multimodality treatment regimens are needed to improve quality of life and survival, which is most important in malignant neoplasms. Since 1998 we have treated 16 children with malignant CNS tumors. All 16 patients have been treated on an interdisciplinary basis and are therefore accompanied by a pediatric neuro-oncology group consisting of a neurosurgeon, pediatric oncologist, and radiotherapist. Depending on tumor histology, child"s age, and extent of surgery, further adjuvant therapy is planned by this group. Newly diagnosed tumors are typically treated by a specific chemotherapy protocol according to a multi-institutional study. In recurrent tumors more individual treatment regimens are considered. Data concerning surgery, adjunctive treatment, complications, and outcome of all patients and four case reports are presented.

    Notes: Summary We report the clinical course and diagnostic findings in two patients with life-threatening Mycoplasma pneumoniae (MP) pneumonia who were treated in the same hospital in the course of only 4 months. The patients were previously healthy adults, aged 31 and 37 years, respectively. In both of them severe complications occurred which coincided with the acute MP respiratory infection.

    Notes: Zusammenfassung Durch Tusche-Injektionen in die Coronararterien konnte gezeigt werden, daß das Glomus pulmonale dem Coronarkreislauf angeschlossen ist. Zusammen mit den supracardialen Paraganglien (Penitschka) ist das Glomus pulmonale als ein Chemoreceptorenfeld für die Herzkranzgefäße zu betrachten. Licht-und elektronenmikroskopische Untersuchungen der Glomuszellen (Glomus pulmonale) und ihrer synaptischen Verknüpfung mit dem Nervensystem ergaben eine morphologische Übereinstimmung mit dem Glomus caroticum. Auf Grund von Durchschneidungsversuchen (Exstirpation des Ganglion nodosum) ließ sich die Innervation des Glomus pulmonale durch den N. Vagus nachweisen. Jene das Glomus pulmonale versorgende Arterie des Coronarkreislaufes besitzt an ihrer elastischen Wegstrecke zahlreiche pressoreceptorische Nervenendigungen. Demnach ist auch der Coronarkreislauf wie der Große Kreislauf mit Chemo- und Pressoreceptorenfeldern ausgestattet. Auch durch physiologische Untersuchungen konnte die funktionelle Bedeutung der Chemoreceptoren im Glomus pulmonale und in den supracardialen Paraganglien für den Coronarkreislauf nachgewiesen werden. Ihre Stimulierung durch örtliche Natriumsulfitapplikationen bzw. durch eine intravenöse Persantininjektion bewirkt eine coronare Mehrdurchblutung. Die Folge der coronaren Mehrdurchblutung ist eine Erhöhung der Sauerstoffspannung im venösen Blut des Sinus coronarius. Der bisher unbekannte Mechanismus der hypoxämischen Coronarerweiterung und die maximalen Coronardurchblutungen bei Anämien wurden als Folge einer Reizung der coronaren Chemoreceptoren unter Hinweis auf die bekannte große Sauerstoffmangelempfindlichkeit der Chemoreceptoren diskutiert: Es besteht eine auffallende Parallelität zwischen dem Grad der Sauerstoffsättigungsminderung, der einerseits eine coronare Mehrdurchblutung verursacht und andererseits eine erhebliche Zunahme der Chemoreceptorenimpulse bewirkt.

    Notes: Summary The immunogold technique, employing antisera with clear-cut specificities, was used to localise different processing stages of pro-opiomelanocortin (POMC) in rabbit melanotropic cells. While the antiserum against γ 3-MSH labelled all the secretory granules including intrasaccular condensations in the Golgi apparatus, antisera against α-MSH only labelled extra-Golgi secretory vesicles (SV). All extra-Golgi SV were likewise labelled with the three antisera against α-MSH used, despite their different specificities for the desacetylated, N-acetylated or C-amidated forms of the peptide. The antibody against β-endorphin also labelled the extra-Golgi SV, while only some SV were labelled with the antibody against γ-endorphin. These results correlate with biochemical data in favour of mainly — if not exclusively — intragranular processing of POMC. Except for γ3-MSH, the cleavage of which could coincide with Golgi packaging of secretory material, other post-translational modifications of the precursor seem to occur when SV are discharged outside the Golgi area. The cleavage of γ-endorphin appears to be a later step in POMC processing, occurring in some mature SV.

    Notes: Zusammenfassung Die elektronenmikroskopische Untersuchung des Nervengewebes in der Wand des Sinus caroticus (Kaninchen) ergab folgende Resultate: Im Adventitia-Media-Bereich erstrecken sich zwei Typen von Axonendigungen. 1. Kleine Axonendanschwellungen mit einem Durchmesser von 600–2000 mμ besitzen zahlreiche Mitochondrien und sind in die Oberfläche von spezifischen Terminalzellen unter Bildung eines Mesaxons eingesenkt. Die Schwannschen Zellen der afferenten Nervenfasern werden somit im Gebiet der Axonendigung durch strukturreiche Terminalzellen (reichliches granuläres endoplasmatisches Retikulum, Mitochondrien, Ribosomen, gut ausgebildete Golgifelder und vesikuläre Anteile) ersetzt. Die verästelten Terminalzellen geraten durch ihre Portsätze mit den elastischen Membranen in Kontakt. 2. Große Endanschwellungen mit auffällig vielen Mitochondrien und Neurofilamenten tubulären Charakters werden ebenfalls von Terminalzellen umfaßt. Der Durchmesser der großen Axonendigungen beträgt 6000–8000 mμ. Die Axonendigung und die Terminalzelle bilden eine morphologische und funktioneile Einheit.

    Notes: Abstract Accumulation of 99mTc-diphosphonate was observed in 2 of 12 patients with liver metastases who had primary adenocarcinoma of the large bowel. The area of excessive radionuclide concentration corresponded well to the location of the hepatic metastases. The literature on this subject is reviewed and a possible mechanism of radionuclide accumulation is discussed.
