    Description / Table of Contents: Zusammenfassung Zweck dieser Untersuchung war es, die Knochenwachstumsrate bei vier unterschiedlich beschaffenen Oberflächen von Kobalt-Chrom-Transplantaten zu vergleichen. Zwei der Implantat-Oberflächen waren mit einer Glaskeramik eigener Entwicklung beschichtet; einer der Beläge war porös. Ein verstärkter Knocheneinwuchs konnte bei den Glaskeramik-Implantaten nicht festgestellt werden. Ferner wurde der Grad der Kontamination durch Metallionen beurteilt, wobei im Falle der Glaskeramik eine signifikante und potentiell schädliche Kontamination durch Metallionen festgestellt wurde. Diese Untersuchung zeigt die Notwendigkeit auf, bessere Verfahren für die Beschichtung von Metall mit Glaskeramik zu entwickeln, um potentiell karzinogene Effekte auszuschließen.
    Notes: Summary The purpose of this study was to compare the rates of bone growth with four different surfaces of cobalt-chrome implants. Two of the implant surfaces were coated by a glass-ceramic of our own composition. One coating was porous. No enhancement of bone ingrowth was found in the glass-ceramic implants. The degree of metal ion contamination was also assessed, and significant, potentially harmful contamination by metal ions was found in the glass-ceramic. This study points out the need for better techniques of coating metal with glass-ceramic to avoid potential carcinogenic effects.

    Notes: [Auszug] 138La decays to 138Ce and 138Ba by /3-decay and electron capture, respectively. Tanaka and Masuda1 developed a dating method which employed the 138La-138Ce decay. Preliminary trial by Masuda and Nakai2 demonstrated the possible geochrono-logical utility of the 138La-138Ba decay. Our recent access ...

    Notes: Summary The crossbridge mechanism leading to oscillation in insect flight muscle is studied theoretically based on a three-state model proposed by Nishiyamaet al. [Biochim. biophys. Acta 460, 523–36 (1977)]. Skeletal muscle as well as insect flight muscle shows oscillatory contraction. We demonstrate this oscillatory contraction in muscle by choosing proper rate constants among the three states of the model. It is established that our model gives out not only Hill's force-velocity relation but also other mechanical properties of skeletal muscle. The model is then compared with two types of experiment by Kawai & Brandt [J. Musc. Res. Cell Motility 1, 279–303 (1980)] and by Steiger & Rüegg [Pflügers Arch. 307, 1–21 (1969)]. Kawai & Brandt obtained the Nyquist plot showing the relation between the phase shift and the amplitude of tension change in response to sinusoidal length changes at various frequencies. Steiger & Rüegg studied the power output and ATPase activity at various frequencies of the length change. Our theoretical results are in good agreement with the results of these two experiments. To determine the crossbridge mechanism which produces the positive power output, spatio-temporal crossbridge distributions in the three states are calculated. It is shown that, after the stretching phase of sinusoidal change in muscle length, the delayed rise of tension is caused by attachment of crossbridges to the active state via the preactive state while the delayed fall is caused by detachment from the active state after release. To obtain the oscillatory property it is not necessary to assume that stretch in muscle length increases the attaching rate as originally proposed by Thorson & White [Biophys. J. 9, 360–90 (1969)].
