    Description / Table of Contents: Résumé Présentation de 65 cas de métatarsalgies par insuffisance d'appui du premier rayon. Les auteurs proposent une classification des différents types de défaut d'appui antéro-interne fondée sur la morphologie du premier rayon. Dans le cas de défaut d'appui antéro-interne sur premier rayon normal, ils distinguent l'horizontalisation isolée du premier rayon, la supination globale de l'avant-pied et l'horizontalisation isolée du premier rayon associée à une supination de l'avantpied. Lorsqu'il s'agit d'horizontalisation isolée du premier rayon, on peut proposer des opérations visant à rétablir un appui antéro-interne normal. La décision de pratiquer un type déterminé d'intervention est fondée sur l'analyse de l'origine de l'élévation du premier rayon. Ces opérations peuvent être tendineuses, osseuses, ou osseuses et tendineuses. Lorsque le défaut d'appui antéro-interne résulte d'une supination isolée de l'avant-pied, le défaut d'appui antéro-interne sera corrigé par une ostéotomie de dérotation du tarse. La supination de l'avant-pied peut être accompagnée par une horizontalisation du premier rayon. Dans ces cas, l'ostéotomie de dérotation du tarse sera complétée par une des opérations pratiquées dans le cas d'élévation isolée du premier rayon. Les indications différentielles de toutes ces intervention sont exposées ainsi que les résultats. Dans le cas de défaut d'appui antéro-interne sur premier rayon morphologiquement anormal, le traitement a été soit conservateur, soit chirurgical. Les résultats des différentes interventions chirurgicales pratiquées afin d'équilibrer la répartition des charges au niveau de l'avant-pied sont présentées.
    Notes: Summary Sixty-five feet with metatarsalgia due to inadequate support by the first ray are presented. A classification of different types of deficient anteromedial support is proposed in relation to the morphology of the first ray. When there is deficient anteromedial support and the first ray is normal, the ray is elevated and may or may not be associated with supination of the forefoot. When there is elevation of the first ray alone, operations are proposed which restore normal anteromedial support. The decision for choosing a particular type of operation is determined by an analysis of the cause of the elevation. These operations can be on the soft tissues, bones or both. When loss of anteromedial support is the consequence of complete supination of the forefoot, this has been corrected by a tarsal derotation osteotomy. Supination of the forefoot may be accompanied by elevation of the first ray. In these cases, the derotation osteotomy has been complemented by one of the operations described in the case of simple elevation of the first ray. The different indications of these surgical procedure are described as well as the results. In the case of deficient anteromedial support with an abnormal first ray, the treatment was conservative or surgical. The results of different operations performed to restore the normal loading under the forefoot are described.

    Notes: Summary The injection of E. Coli into the tail of the epididymis in the rat caused epididymitis. In 20% of the cases, the inflammation is spread through the lymphatic system to the testis. The germinal cells are destroyed in 50% of the cases by the second day, and are not reestablished for several months. Signs of testicular inflammation are not found. The destruction seems to be caused by E. Coli toxins, as shown by injections of killed bacteria.

    Notes: Summary Ruthenium red staining and tannic acid fixation were used to analyse the fine structure of embryonic mouse dental basement membrane in intact first mandibular molars or in EDTA-isolated dental papillae. Preameloblasts are separated from extracellular matrix proper by a basal lamina that contains regularly arranged proteoglycan granules of about 10 nm in diameter. This distribution pattern is particularly evident in the inner and outer lamina rara of the basal lamina associated with EDTA-isolated dental papillae. The plasmalemma of preameloblasts demonstrates electron dense plaques on the inner leaflet. Ruthenium red positive granules (50 nm in diameter) coat non-striated and striated fibrils of the matrix. Hyaluronidase treatment digested the ruthenium red positive granules. Tannic acid fixation allowed the demonstration of filaments within the lamina rara interna, connecting the lamina densa with plasmalemma of preameloblasts. These observations are discussed in the context of the terminal differentiation of odontoblasts.
