    Description / Table of Contents: Résumé Des métaux poreux et des céramiques sont implantés dans l'osin vivo et sont prélevés, après différents intervalles, pour étudier histologiquement la colonisation tissulaire. Les implants prélevés sont fixés avec les tissus environnants et inclus dans des epoxy-résines, de faible viscosité. Les échantillons sont coupés à l'aide d'une scie diamantée et fixés sur des lames pétrographiques, pour être ensuite amincis à environ 75 μm. Ils sont légèrement colorés au bleu de méthylène et à l'alizarine rouge S, qui donne un bon contraste entre tissus durs et mous et démontrent la présence d'os calcifié dans les implants poreux métalliques et céramiques.
    Abstract: Zusammenfassung Poröse Metall- und Keramikstücke wurden in vivo in Knochen implantiert und nach verschiedenen Intervallen entnommen, um histologisch zu untersuchen, wie weit sie ins Gewebe eingewachsen waren. Die entnommenen Implantate mit dem sie umgebenden Gewebe wurden fixiert, dehydriert und in ein niedrigvisköses Epoxy-Harz eingebettet. Die Proben wurden mit einer Diamantsäge in dicke Schnitte zerteilt, auf Steinscheiben zementiert und von Hand auf etwa 75 μm geschliffen. Sie wurden mit Methylenblau und Alizarin-Rot S schwach gefärbt; dies ergibt einen großen Kontrast zwischen Knochen und Weichgewebe und zeigt die Bildung von verkalktem Knochen innerhalb poröser Metall- und Keramik-Implantate deutlich.
    Notes: Abstract Porous metals and ceramics were implanted in bonein vivo and retrieved at intervals for histological evaluation of tissue ingrowth. Recovered implants with surrounding tissues were fixed, dehydrated and embedded in a low-viscosity epoxy resin embedding medium. The embedded samples were cut into thick sections with a diamond saw, cemented to petrographic slides, and hand-ground to approximately 75 μm. They were lightly stained with methylene blue and Alizarin Red S, which provided great contrast between the bone and soft tissues, and clearly demonstrated the formation of calcified bone within porous metal and ceramic implants.

    Notes: The effects of tension on the absorbance of water at 60°C into neat and glass-bead-filled, cross-linked polyester are reported. Experimental apparatus and procedure to determine water uptake for these materials subjected to three tensile stresses in the range of 0 to 30 percent of the breaking stress of the neat dry polyester are described. It was found, for bead-filled samples, that a load of approximately 4.9 × 106 N/m2 caused the absorption level to increase by 30 percent over that of an unloaded sample. Tensile load was found to have no effect on the absorption characteristics of neat polyester. However, breaking stress was reduced to less than 15 percent of that in the dry neat material. Optical microscope examinations of damage at the fracture surfaces and at the sample cores indicate that the excess moisture uptake in bead-filled samples was not due to microcrack formation.
