    Notes: Zusammenfassung 1. Auf Grund von Beobachtungen an 691 Ff.-Kranken werden das Vorkommen und die Ursachen von nachträglichen Temperaturerhöhungen in der Rekonvaleszenz näher erörtert. 2. Es wird eine Differentialdiagnose dieser genetisch verschiedenen Fieberzustände versucht und gezeigt, daß außer dem sog. „echten“ Nachfieber vorübergehende Temperatursteigerungen durch Spätkomplikationen und infolge einer besonderen Labilität der Wärmeregulation vorkommen. Für eine Auslösung des Nachfiebers durch allergische Vorgänge im engeren Sinne fanden sich keine sicheren Anhaltspunkte. 3. Vom praktischen Standpunkt aus scheint die Kenntnis dieser verschiedenen Nachfieberzustände deshalb besonders wichtig, damit nicht zufällige Kombinationen des Ff. mit anderen Infektionskrankheiten (Wolhynisches Fieber, Bauchtyphus, Lungentbc. usw.) übersehen werden.

    Notes: Zusammenfassung 1. Die ikterische Blutgerinnungsstörung ist neben Prothrombinmangel auch durch einen erhöhten Blutantithrombintiter bedingt. 2. Der erhöhte Antithrombintiter im ikterischen Blut wird hervorgerufen durch Erhöhung der Thrombinaffinität eines oder mehrerer Blutproteine. 3. Vitamin K beeinflußt neben seiner bekannten Wirkung auf die Prothrombingerinnung auch die Störung im Bluteiweiß beim Ikterus im günstigen Sinne.

    Notes: Abstract 1. Respiration rates of broad-bean (Vicia faba) mitochondria were studied as a function of temperature. Arrhenius plots of all membrane-bound enzymes, as obtained with saturating substrate concentrations, revealed a break in the lower temperature range. That break was considered to indicate a phase transition of membrane phospholipids, characteristic for chilling-sensitive plants. A second discontinuity at 30°C occurred only with activities linked to energy conservation. — 2. The activation energies for the oxidation of NAD+-linked substrates differ between states 3 and 4. State 3 respiration of NAD+-linked substrates is the result a superimposition of two branches of electron transport, which can be separated by different sensibilities to rotenone. A characteristic temperature dependency of the respiratory control, as well as a shift of the low temperature break in the Arrhenius plot toward a higher temperature after state 4 to state 3 transition, are calculated to be caused by the superimposition of the two branches. — 3. The temperature dependency of the oxidation of extra-mitochondrial NADH and of succinate differs remarkably from that of the oxidation of matrix-NADH. It has been concluded that the rotenone-resistant oxidation of matrix-NADH and the oxidation of external NADH are mediated via different pathways with individual regulation sites.

    Notes: Abstract Mitochondria from Vicia faba L. exhibit two pathways for the oxidation of endogenous NADH. One pathway is rotenone-sensitive and includes three phosphorylation sites, the other one is rotenone-insensitive and by-passes site I. This by-pass is located in the area of flavoproteins, but several lines of evidence suggest that the rotenone-insensitive oxidation of matrix-NADH is not mediated by the external NADH dehydrogenase. With saturating substrate concentrations the two pathways are superimposed in state 3 while in state 4 the electrons are transferred only via the by-pass. The rotenone-resistant electron flux is obviously regulated from the substrate side. We suggest that the function of the by-pass is to regulate the NADH/NAD+ ratio of the matrix space.

    Description / Table of Contents: Summary Collagen types I, II and III from man and calf are distinctly different with respect to their effect on the induction of the aggregation of human platelets. Collagen type III was found to be a particularly potent inducer of platelet aggregation. The pathogenetic implications of these observations are briefly discussed.
    Notes: Zusammenfassung Die Kollagentypen I, II and III von Mensch und Kalb weisen in löslicher und strukturierter Form deutliche Unterschiede in ihrer Wirkung auf die Aggregation menschlicher Thrombocyten auf. Eine besonders stark aggregierende Wirkung wurde für das Typ III Kollagen gefunden. Die pathogenetische Bedeutung dieses Befundes wird kurz diskutiert.

    Notes: Summary The complex, erupting nematocyst batteries of Nanomia cara are described. In addition to the cnidoband, the battery has a central axis containing longitudinal muscles and nerves that run right through to the terminal filament. In addition, an elastic strand lies coiled within the battery. After eruption of the battery, this strand keeps the prey attached to the tentacle. The strand bears hook-like spicules, equipped with barbs that project beyond the surface. Electron microscopy shows that the elastic strand is a mesogloeal structure tunnelled through and through with cellular processes deriving from both ectoderm and endoderm and that the spicules lie in cellular pockets in the interior of the elastic strand. There is nothing in the structure of the spicules or their cellular sheaths to suggest an origin from nematocysts. Energy dispersive X-ray microanalysis shows strong peaks for calcium and for phosphorus in the spicules, indicating that the mineral present in them is an apatite. An organic matrix is also found in the form of fine filaments and a granular axial structure. The spicules are arranged in a linear series along the elastic strand showing progressive increase in size and structural elaboration.

    Description / Table of Contents: Summary Direct bracket-bonding has many advantages since it means improved prophylaxis of caries and of periodontitis. Separation of teeth prior to bonding and the closure of band spaces are no longer necessary. In addition aesthetics is much better compared to conventional bands. However, an important disadvantage of direct bonding appears to be the failure rate. The present study shows that after 38 months merely 93,4% of maxillary brackets and 90,4% of mandibular brackets are still in place. Two thirds of those brackets which were finally lost failed after 15 months. In about 90% of the investigated failures the fracture was observed to be between the bracket metal and the adhesive.
    Abstract: Résumé Les avantages de la technique adhésive pour fixer les brackets sont: Une meilleure prophylaxie de la carie et des parodontopathies, la suppression des séances de séparation nécessaires, la suppression de la fermeture d'un espace restant après la dépose des bagues et une meilleure esthétique en comparaison avec les bagues conventionnelles. Toutefois, un inconvénient important de cette technique est la proportion élevée des échecs. Le présent exposé met en évidence qu'après une période de 38 mois, 93,4% des brackets au maxillaire supérieur et 90,4% des brackets au maxillaire inférieur étaient encore inchangés in situ. 2/3 de tous les brackets enlevés après 38 mois, s'étaient déjà détachés après une période d'environ 15 mois. Dans environ 90% de tous les cas, la rupture s'était produite entre le métal et l'adhésif.
    Notes: Zusammenfassung Vorteile der Bracket-Adhäsivtechnik sind die verbesserte Karies- und Parodontalprophylaxe, nicht mehr notwendige Separiersitzungen, entfallender Restlückenschluß nach der Entbänderung und nicht zuletzt die verbesserte Ästhetik gegenüber konventionellen Bändern. Als wichtiger Nachteil dieser Technik erweist sich aber die erhöhte Mißerfolgsrate. Der vorliegende Beitrag zeigt, daß nach 38 Monaten noch 93,4% der Brackets im Oberkiefer und 90,4% der Brackets im Unterkiefer unverändert in situ sind. Zwei Drittel aller nach 38 Monaten gelösten Brackets hatten sich schon nach etwa 15 Monaten gelöst. In etwa 90% aller Fälle erfolgte der Bruch zwischen Metall und Adhäsiv.

    Notes: Abstract To investigate the value of the extrafoveal pattern electroretinogram for evaluation of local retinal defects, electroretinographic responses to contrast reversal stimulation were recorded at various locations in the central and midperipheral retina. Normal values were established in 20 eyes, and spatial selectivity at different retinal eccentricities was determined in four eyes. The response amplitude was found to decrease steeply from the fovea until about 12° eccentricity and to decline only slowly thereafter. For central stimulation a clear attenuation for coarser patterns was observed. At 20° and at 30° eccentricity the spatial tuning function exhibited a bandpass characteristic, with the maximum amplitude shifting to lower spatial frequencies. Despite the relatively low peripheral amplitudes a satisfactory signal to noise ratio of the second harmonic responses can be obtained by Fourier analysis, which improves clinical applicability. The comparison of sensitivity in the upper and lower retina revealed a considerable asymmetry, with responses in the upper retina approximately 20% higher. No significant difference, however, was found when the temporal or nasal retina was stimulated. The reproducibility of these results is high enough to encourage clinical studies. A case of retinal venous branch occlusion exemplifies the applicability of this technique in eccentric fundus lesions.
