    Description / Table of Contents: Zusammenfassung An Syrischen Hamstern wurde gezeigt, daß sich Nitrosopiperidin (NP) quantitativ nach subcutaner Injektion im mütterlichen Blut für mehr als 8 Std nachweisen läßt, während die Substanz zu diesem Zeitpunkt in Placenta, Fetus und Fruchtwasser nicht mehr meßbar war. In gleichen Geweben fanden sich nur Spuren von N6MI nach 2 Std. Die langzeitige transplacentare Wirkung einer Einzeldosis von NP war schwach. Dies zeigt sich an der geringen Rate von Tumoren im Respirationstrakt (P-Generation: 54%; F1 Generation: 4%). Einige Neoplasmen, die bei den behandelten Müttern nicht gefunden und gewöhnlich nicht bei Kontrollen beobachtet wurden, traten im Verdauungstrakt der Jungen auf. Diese Tumoren wurden als Ausdruck einer transplacentaren Grenzwirkung gewertet. Geschwülste anderer Organe (Urogenitaltrakt, reticulo-endotheliales System, endocrine Organe und andere Gewebe) zeigten Häufigkeitsschwankungen, wie sie in unserer Hamsterkolonie beobachtet wurden.
    Notes: Summary Nitrosopiperidine (NP) was found in Syrian hamsters quantitatively in the maternal blood for more than 8 h after subcutaneous injection, whereas it disappeared from placenta, fetus and amniotic fluid within the same time period. For N6MI, only traces were seen after 2 h in the same tissues. The long-term transplacental effect of a single dose of NP was weak, as demonstrated by a low respiratory tract tumor incidence (P-generation: 54%, F1 generation: 4%). Some tumors occurring in the digestive tract of exposed young were not found in their mothers and not commonly observed in controls. These tumors were considered a borderline transplacental effect. Tumors of other sites (i.e., the urogenital and genital tracts, reticuloendothelial system, endocrine organs and other tissues) corresponded in incidences to the overall fluctuations observed in this hamster colony.

    Notes: Summary Metrizamide CT cisternograms were performed on 39 patients with a clinical diagnosis of CSF abnormalities; 20 of these patients underwent radionuclide cisternography as well. Comparison of metrizamide CT and RN cisternography revealed good correlation in the degree, extent, and time sequence of ventricular reflux as well as the extent of cortical staining and cisternal filling. Metrizamide cisternography had the advantage of excellent anatomic detail and lower exposure dose, although minor complications were more frequent with this technique. Metrizamide CT cisternography has a potential to become the preferred method of evaluating patients with abnormal CSF dynamics.

    Notes: Summary This report concerns a group of 49 patients who had been diagnosed as having gliomas on the basis of CT scans plus angiograms and for whom histologic proof was available. Ninety percent were found to be gliomas, 4% were metastases, and histology was unclear in the rest. Combining the CT criteria of inhomogeneous enhancement and surrounding edema with one or more of three angiographic signs (early venous drainage, stain, abnormal vessels) allowed a more confident diagnosis of glioblastoma.

    Notes: Abstract Venous vascular masses in the neck are rare entities in the pediatric population. Aneurysmal dilatation or ectasia of the superficial cervical vein, the so-called “venous angioma” is a very uncommon condition. A 12-year old female with venous angioma involving the right neck is described. The preoperative diagnosis was confirmed by angiography.

    Description / Table of Contents: Sommaire Un nouveau type de respirateur électrophrénique synchrone, développé par nos soins, a été appliqué à des chiens souffrant d'une défaillance respiratoire incomplète, en bloquant la lère corde thoracique ainsi que les branches C6 et C7 des deux nerfs phréniques (en incluant quelquefois une branche C5 unilatérale). Ce respirateur a stimulé le moignon distal du nerf phrénique en synchronisation avec les impulsions faibles partant du moignon proximal du nerf, permenttant ainsi la régulation convenable de la respiration. Le volume oxygénant minime et les pressions partielles des gaz expirateurs de fin de respiration se trouvaient automatiquement réglés par le respirateur pour passer de l'état d'hypoventilation au niveau normal de la régulation accompagné d'un dépassement et d'oscillations amorties. Les gaz sanguins artériels se sont également rétablis d'une façon satisfaisante. L'aspiration de fortes concentrations d'acide carbonique pendant la respiration électrophrénique synchrone a provoqué des réponses similaires à celles observées pour les chiens normaux. Ainsi on a trouvé que le respirateur électrophrénique synchrone pouvait fonctionner comme élément du système de réaction respiratoire.
    Abstract: Zusammenfassung Wir entwickelten ein neues synchrones elektrisches Beatmungsgerät für das Zwerchfell, das auf Hunde mit unvollständigem, Atmungsausfall angewandt wurde, der durch eine Blockierung des 1. thorakalen Stranges und der Verzweigungen C6 und C7 von beiden Zwerchfellnerven verursacht worden war (manchmal einschließlich einer einseitigen C5-Abzweigung). Dieses Atemgerät reizte den distalen Stummel des Zwerchfellnerven synchron mit den schwachen Impulsen vom proximalen Stummel des Nervs, so daß sich eine Geeignete Steuerung der Atmung ergab. Das äußerst geringe Beatmungsvolumen und die Teildrücke der ausgeatmenten Gase am Ende des Atemluftvolumens wurden atuomatisch durch dieses Beatmungserät vom Zustand der Unterbeatmung in eine normale Steuerung verwandelt, verbunden mit Übersteuerung und gedämpften Schwingungen. Die Gase des arteriellen Blutes erholten sich hinreichend von der Unterbeatmung. Bei Einatmung von starken Kohlendioxydkonzentrationen während der synchronen elektrischen Zwerchfellbeatmung ergaben sich ähnliche Reaktionen wie auch bei normalen Hunden beobachtet wurden. Auf diese Weise wurde festgestellt, daß das synchrone elektrische Beatmungsgerät für das Zwerchfell als Element der Beatmungsrückkoppelung eingesetzt werden könnte.
    Notes: Abstract A new type of synchronous electrophrenic respirator developed by the authors has been applied to dogs with incomplete respiratory failure produced by blocking the 1st thoracic cord and the C6 and C1 branches of both phrenic nerves (sometimes including a unilateral C5 branch). This respirator stimulated the distal stump of the phrenic nerve synchronously with the feeble impulses from the proximal stump of the nerve, resulting in a suitable control of respiration. The minute ventilatory volume and the partial pressures of the expiratory end-tidal gases were adjusted automatically by this respirator, from the state of hypoventilation to the normal control level, accompanied by an overshoot and damped oscillations. The arterial-bloodgases also exhibited a satisfactory recovery from the hypoventilation. The inhalation of high concentrations of carbon dioxide during the synchronous, electrophrenic respiration produced similar responses to those observed in normal dogs. Accordingly, it was found that the synchronous electrophrenic respirator could operate as an element of the respiratory-feedback system.
