    Notes: Abstract Bovine factor VIII/platelet aggregating factor was adsorbed onto gold granules and the protein-gold complex added to either formalin-fixed or fresh washed human platelets. Following aggregation, binding of gold granules to the platelets was measured by monitoring the optical density of colloidal gold remaining in the supernatant. Scatchard analysis of binding data indicated that multiple classes of binding sites were present. The number of high affinity binding sites per formalin-fixed platelet dependend on the concentration of ristocetin: 420 gold granules were calculated to bind at 1.4 mg/ml of ristocetin, 610 at 0.6 mg/ml of ristocetin and 875 when no ristocetin was added. Fresh washed platelets bound 1350 granules per cell in the absence of ristocetin. We conclude that during platelet aggregation, induced by bovine factor VIII, the binding sites on the platelet surface are only partially occupied.

    Description / Table of Contents: Zusammenfassung Es wird eine einfache Operation zur Refixation des Retinaculum superius tendinis peronaeum zur Behandlung der habituellen Peronäussehnenluxation beschrieben. Das auspräparierte Retinaculum wird in einem Knochenschlitz am Außenknöchel mit Hilfe einer Schraube fixiert. Die Operation eignet sich auch zur Behandlung der habituellen Tibialis-posterior-Sehnenluxation.
    Notes: Summary Simple operation for refixation of the superior retinaculum of the peronaeal tendon for treatment of recurrent dislocations of the peronaeal tendon is described. The prepared retinaculum is fixed into a cleft of the lateral malleolus with a screw. This operation is also suitable for treatment of the recurrent dislocation of the posterior tibialis tendon.

    Description / Table of Contents: Zusammenfassung Die Auswirkungen von Cyclophosphamid wurden bei jungen männlichen Ratten untersucht, 2, 5 und 9 Tage nach Beendigung einer zweiwöchigen Verabreichung, die alle 2 Tage intraperitoneal erfolgte. Die cytostatische Wirkung wurde durch die Leukozytenzählung im arteriellen Blut bestimmt. Die Leukozytenwerte waren am zweiten Tage um 72% reduziert und erreichten wieder eine normale Höhe am 9. Tag nach einer überschießenden Leukozytose am 5. Tag. Verglichen mit Kontrolltieren hatten die behandelten Ratten ein signifikant reduziertes Körpergewicht, eine herabgesetzte Biegefestigkeit der Metaphysen und ein verringertes Längenwachstum des Femur. Die Torsionsfestigkeit der Femurdiaphyse und die Festigkeit der verletzten Haut waren nach 2 Tagen nicht verändert, aber nach 5 und 9 Tagen signifikant herabgesetzt. Die Dehnungsfestigkeit der unverletzten Haut zeigte keine Verānderung durch das Medikament. Vom 5. bis zum 9. Tag nach Absetzen der Medikation zeigten die Kurven der Kontrollgruppe und der behandelten Tiere parallele Verläufe bezüglich der metaphysären Knochenfestigkeit, des Knochenlängenwachstums und der Zugfestigkeit der Hautwunden. Dies kann als Hinweis dafür gewertet werden, daß die Auswirkungen des Medikamentes sich etwa 1 Woche nach Beendigung der Verabreichung zurückbilden.
    Notes: Summary The effects of cyclophosphamide were studied 2, 5 and 9 days after terminating a two-week every-second-day intraperitoneal medication in young, male rats. The cytostatic effect was assessed by counting white blood cells (WBC) in arterial blood. WBC counts were reduced by 72% of control values at 2 days and regained normal values at 9 days after an overshooting leucocytosis at 5 days. Compared to control animals, the treated rats had significantly reduced body weights, metaphyseal bending strength and longitudinal growth of the femur at all time intervals observed. The torsional strength of the femur diaphysis and the strength of wounded skin were not affected at 2 days, but significantly reduced at 5 and 9 days. The tensile strength of intact skin was not found to be affected by the drug. From the 5th to the 9th day after ending medication, the curves for control and treated animals were assuming parallel slopes regarding metaphyseal bone strength, longitudinal bone growth and tensile strength of wounds. This may indicate reversion of the drug effects approximately one week after terminating medication.
