    Description / Table of Contents: Zusammenfassung Werkstoffe aus Kohlenstoff, Kunstharz und Keramik haben vor allen Dingen in der Endoprothetik besonderes Interesse gefunden. Abriebgroße Mikropartikel von Kohlenstoffen verschiedener Module, Glaskeramik, Al2O3 und Kunstharz wurden ins Knie, Tibia und Abdomen von Ratten implantiert. Vorallen Dingen nach Implantation in den Knochen kommt es zum lymphogenen und hämatogenen Transport der Mikropartikel in die Lunge. Veränderungen der Organgewichte von Thymus, Leber und Milz nach Implantation von Glaskeramik bzw. Höchstmodul-Kohlenstoff könnten auf mögliche systemische Wirkungen auf das RES hinweisen. Die lokale Verträglichkeit der pulverisierten Werkstoffe war in mikromorphologischen und rasterelektronenoptischen Untersuchungen als gut zu bezeichnen.
    Notes: Summary In the past few years much interest has been focused on carbon, synthetic resin, and ceramic biomaterials, especially for orthopedic implants. Rubbed off microparticles of carbons of different modules, grains of ceramic glass, alumina and resin were tested in rats after implantation into the knee joint, the medullary cavity of the tibia and into the peritoneal cavity. The microparticles were carried off hematogenously and lymphatically into the lungs mostly after implantation into the bone. Alterations of the organ weights of thymus, liver and spleen after implantation of ceramic glass and carbon of ultrahigh module seem to indicate possible effects on the RES. Micromorphologic and scanning electron microscopic examinations showed good local compatibility of the grains.

    Notes: Abstract An in vitro system was developed capable of testing the accuracy and reproducibility of pulse oximeter readings. The pulse oximeter probe receives signals through a pulsating blood cuvette. The development of the design of the cuvette is described. Using the final design (or ‘model finger’), a comparison is made between readings from a Datex Satlite pulse oximeter (SpO2) and saturation values obtained by use of a multiwavelength bench oximeter (SaO2). Linear regression analysis of the data gives SpO2=0·88 SaO2+11·2 (r=0·979, p〈0·001).
