    Description / Table of Contents: Résumé Complétant un travail antérieur de l'anatomie macroscopique et histologique de la veine ombilicale de l'adulte, une étude histologique et radiologique a été faite sur des cadavres afin de déterminer le trajet suivi par des sondes ou des cathéters introduits dans cette veine afin d'obtenir un accès sur le système porte. Bien qu'il persiste une partie de la lumière initiale, son diamètre est trop étroit (approximativement 0,2 mm) pour admettre des sondes et des cathéters. Les instruments se fraient un passage artificiellement à travers une zone interne lâche qui est la ≪lumière apparente≫ de la veine. Cette zone centrale qui est formée après la naissance est plus pâle et de consistance moins ferme que les zones périphériques mais elle devient plus fibreuse avec les années et sa reperméabilisation est alors plus difficile. A la jonction veine ombilicale-veine porte, la sonde est arrêtée par la paroi de la branche gauche de la veine porte qui se divise à ce niveau (récessus ombilical). Une perforation de cette paroi par pression de la sonde permet de pènètrer dans le système porte. Sans une reperméabilisation préalable, l'injection de liquide de contraste dans la lumière apparente de la veine ombilicale ne pénètre pas dans le système porte.
    Notes: Summary Following a previous study of the gross anatomical and histological features of the adult umbilical vein, a histological and radiological investigation has been made on post-mortem material, to determine the route taken by probes and catheters introduced into the hemisected vein, to obtain access to the portal system. Although a residual part of the original lumen persists, it is far too small in diameter (approximately 0.2 mm) to admit probes and catheters. The instruments traverse a loose inner zone (the ‘apparent lumen’) and form a false passage within it. This zone, which is formed postnatally, is paler and of softer consitency than the surrounding zones, but since it becomes more fibrous and contracted in later life, instrumentation could prove more difficult in the elderly. At the umbilical-portal junction, the probe is arrested by the diverging right wall of the terminal expansion of the left branch of the portal vein (the recessus umbilicalis). Local rupture of the inner part of the wall by probe pressure gives access to the portal system. Without prior probing, contrast medium injected locally into the apparent lumen does not reach the portal system.

    Notes: Summary Concentrations of transcortin binding sites and apparent dissociation constants for corticosterone have been measured in the blood of control and thyroidectomized chick embryos. The levels of corticosterone binding are quantitatively similar in normal and thyroidectomized embryos and vary in parallel during development.

    Notes: Abstract Double differential cross sectionsd 2 σ/dΩdE were measured for high energetic electrons emitted in heavy ion collisions. Electrons were detected in the energy range of 60 keV-500 keV for various target projectile combinations 66≦Z u =Z t +Z p ≦145 and projectile velocities between 7 % and 10 % of the speed of light. Clear evidence was found that these electrons stem from the united atom formed during the collision. Slope and height of the spectra are discussed with respect to the momentum distribution of strongly bound states (i.e. theL-shell) at momenta far above the mean value. In addition for the systems S, Ni, Br→Pb electrons were detected in coincidence withK x-rays of Pb. By this method the contribution of theK-shell of the combined system to the total spectrum could be separated. Binding energies of theK-shell were estimated by a slope comparison between the coincident and single spectrum. The resulting values are close to the united atom limit.
