    Notes: Zusammenfassung Mit Hilfe der Lupe wurden an 15 Objekten (davon 2 Kindern) von den zum Herzen ziehenden Nerven Ursprung, Plexusbildung und Verzweigung auspräpariert und dabei auf die Variabilität und die Unterschiede von links und rechts besonders geachtet. Im Prinzip können jederseits 3 Vagusäste (Rami cardiaci craniales, medii und caudales) und 3 Sympathicusäste (Nervi cardiaci craniales, medii und caudales) unterschieden werden. Von diesen Herznerven entspringen besonders rechterseits die Rr. cardiaci medii und caudales mit mehreren Wurzeln vom Recurrens bzw. vom Vagus, während links die Zahl der Wurzeln nicht so groß ist. Die Nn. cardiaci caudales lassen links ventrale und dorsale Äste in bezug auf die Aorta unterscheiden. Der ventral von der Aorta gelegene Plexus cardiacus superficialis wird aus 4 Nerven aufgebaut, die vorne links dem Aortenbogen aufliegen, und zwar von rechts nach links N. cardiacus caudalis dexter, N. cardiacus cranalis sinister, R. cardiacus cranalis sinister und N. cardiacus caudalis anterior sinister. Die übrigen Nerven strahlen in den Plexus cardiacus profundus ein, mit dem auch der Plexus superficialis unter dem Aortenbogen zusammenhängt. Der rechts und dorsal vom Aortenbogen und teilweise auch dorsal von der A. pulmonalis gelegene Plexus profundus ist weitaus stärker als der Plexus superficialis. Die Hauptmasse des Plexus cardiacus profundus zieht zu den Coronararterien, es werden auch die Äste zur Hinterwand des rechten Vorhofes — Nachbarschaft des Sinusknotens — und direkt in den Kammerkegel beschrieben. Wenn auch eine gewisse Variabilität besteht, so lassen sich alle größeren Äste immer wieder an charakteristischen Stellen auffinden. Da teilweise schon im Halsgebiet, immer aber im Brustbereiche zahlreiche Verbindungen zwischne Vagus- und Sympathicusästen bestehen, handelt es sich im Herzbereich durchwegs um gemischte Nerven, d. h. solche, die Vagus- und Sympathicusfasern enthalten, so daß aus der makroskopischen Darstellung über die Funktion nichts ausgesagt werden kann. Kurz besprochen wird auch die Lage der bei der Präparation aufgefundenen Knötchen, die teilweise als Paraganglien zu bezeichnen sind.

    Description / Table of Contents: Résumé Du sérum non chauffé normal de lapin et de rat stimule la résorption osseuse en culture de tissu. Cet effet est augmenté, lorsque le sérum est incubé avec un précipité antigène-anticorps. Du sérum chauffé avant traitement par le précipité antigène-anticorps n'a pas d'effet sur la résorption osseuse. La stimulation de la résorption osseuse par le sérum est associée à une apparition d'ostéoclastes. Ces résultats semblent indiquer l'existence d'un facteur sensible à la chaleur dans certains sérums, qui stimule la résorption osseuse. Il n'a pas pu être établi si ce facteur est un constituent du complément.
    Abstract: Zusammenfassung Unerhitztes, normales Serum von Kaninchen und Ratten regt die Knochenresorption in der Gewebekultur an. Diese Wirkung wird erhöht, wenn das Serum mit einem Antigen-Antikörper-Niederschlag inkubiert wurde. Serum, welches vor der Behandlung mit Antigen-Antikörper-Niederschlag erhitzt wurde, hatte keine Wirkung auf die Knochenresorption. Die Stimulation der Knochenresorption durch Serum ging mit Osteoclastenbildung einher. Unsere Ergebnisse stimmen mit der Annahme überein, daß ein hitzelabiler Faktor in einigen Seren vorkommt, welcher die Knochenresorption anregt. Unsere Untersuchungen geben keinen Aufschluß darüber, ob dieser Faktor ein Bestandteil des Komplementes ist oder nicht.
    Notes: Abstract Unheated-normal rabbit and rat sera stimulate bone resorption in tissue culture. The magnitude of this effect is enhanced when the sera were incubated with an antigen-antibody precipitate. Sera heated prior to treatment with antigen-antibody precipitate had no effect on bone resorption. The stimulation of bone resorption by sera was associated with osteoclast formation. Our results are consistent with a heat labile factor in some sera which stimulates bone resorption. Whether this factor is a component of complement or not is not answered by our studies.

    Studies on the relationship between changes in radiographic bone height and probing attachment (1994)

    Notes: Abstract The aim of this investigation was to determine the relationship between loss of radiographic crestal bone height and probing attachment loss. As part of this aim, we are introducing a new method for determination of a threshold for significant probing attachment loss which takes into account the error contributed by alteration in tissue tone. 57 adults with established periodontitis were selected. Radiographs were taken using the Rinn alignment system. Crestal change was determined from bone height measurements on digitized images of pairs of radiographs using the “side-by-side” technique of analysis developed recently by us. Probing attachment loss was measured using the Florida electronic probe system. Radiographic and probing measurements were made at baseline and after 1 year. No treatment was given during this period. A direct and significant relationship was observed between radiographic bone loss and probing attachment loss on a site basis (p= 0.0001, r2= 0.018) and between subject means (p= 0.0014, r2= 0.16). Radiographic and probing attachment change at all categories of sites, dichotomously classified as to not changing or loosing indicated 13% of sites were loosing by measurement of radiographic change and 9.6% were Loosing by measurement of attachment change. Concordance in radiographic and attachment level change was found in 82% of sites examined. The relative diagnostic import of change in probing attachment or change in radiographic bone height requires treatment outcome studies based on use of diagnostic information of the 2 measuring techniques used singly and in combination.

    A perspective on periodontal disease activity measurements (1988)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Abstract Studies utilizing serial standardized periapical radiographs for measurements of alveolar bone height and for digital subtraction and changes in clinical probing attachment level have suggested that adult periodontitis may exhibit periods of exacerbation and remission at specific sites. The use of such serial examinations for the determination of disease activity must be interpreted with caution since the different methods for the assessment of disease activity have different levels of sensitivity and specificity and because such sequential methods integrate disease activity and do not provide an instantaneous measure of activity. An ideal test for disease activity would approach an instantaneous measure of disease activity and would not integrate activity over time.

    Techniques for assessing alveolar bone mass changes in periodontal disease with emphasis on 125I absorptiometry (1983)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Abstract. No practical methods are presently available for measurement of alveolar bone activity at one instant of time. However, roentgenological methods making measurements at 2 different times can be used to assess alveolar bone activity. The most sensitive, specific and accurate method for this purpose presently in use is 125I absorptiometry. This method has the further advantage of giving the patient minimal radiation exposure. New methodology is under development which obviates the need for fixed geometry and could provide a 3-dimensional image of alveolar bone.
