    Notes: Abstract A direct comparison of the joint-imaging properties of inflammation-specific- and non-specific monoclonal antibodies (Mabs) was possible in a patient suffering from long-standing, severe rheumatoid arthritis (RA). This patient received an anti-CD4− and an anti-carcinoembryonic antigen (anti-CEA) Mab, both labelled with technetium-99m, 9 days apart from each other. The anti-CD4 Mab was superior to the isotype-matched anti-CEA Mab in imaging inflamed joints. In the knee joint, the target-to-background ratio of the synovial membrane (SM) activity in comparison to that of adjacent large vessels was 1.22 (SM/muscle 1.55) for the anti-CD4 Mab and 0.53 (SM/muscle 0.92) for the anti-CEA Mab, in both cases 4 h after injection of the immunoglobulin. Since the CD4 antigen is present on the surface of T-helper lymphocytes and macrophages infiltrating the inflamed synovial membrane, imaging with the anti-CD4 Mab may allow more specific detection of inflammatory infiltrates in RA.

    Notes: Abstract CD4 expressing T-lymphocytes are involved in the pathogenesis of rheumatoid arthritis, so the possibility of using radiolabelled CD4-specific antibodies to localise diseased joints was studied. Prospectively six patients with rheumatoid arthritis were investigated. Five of them received 200–300 μg of a 555 MBq technetium 99m CD4-specific antibody (MAX.16H5) and were examined with three phase bone scans. Max.16H5 (IgG1) was labelled according to the mercaptoethanol (Schwarz) method. Lymphocytes of one patient were isolated on a Ficoll-Hypaque gradient and labelled with the antibody in vitro. Scans were performed 1.5 h, 4 and 24 h post injection in anterior and posterior views. In all patients, diseased joints could be clearly imaged at as early as 1.5 h. The localisation of the diseased joints correlated (P〈0.01) with the clinical signs, with the early methylene diphosphonate (MDP) scan (P 〉 0.01) and only weakly with the late bone scan (P 〉 0.05). According to these data we conclude that99mTc-labelled CD4-specific antibodies specifically image actively diseased joints in rheumatoid arthritis.

    Description / Table of Contents: Synthesis of Crystalline Metal Silicate Hydrates of Layer StructureThe purpose of this paper is the synthesis of metal silicate hydrates by means of hydrothermal crystallization from the ternary systems M2/nO—SiO2—H2O (M = Li, Na, K, Ca, Mg). The prepared products, the sodium silicates ilerite, magadiite, and kenyaite and a potassium silicate hydrate, are species of crystallization sequences of a hydrothermal quartz formation process at low temperatures. The product sequences, obtained under different crystallization conditions are given and discussed.
    Notes: Gegenstand der Arbeit ist die Synthese von Metallsilicathydraten (M—SH) mit Schichtstruktur durch hydrothermale Kristallisation im ternären System M2/nO—SiO2—H2O (M = Li, Na, K, Ca, Mg). Die erhaltenen Produkte, die Natriumsilicathydrate Ilerit, Magadiit und Kenyait und ein Kaliumsilicathydrat sind Bestandteile von Produktfolgen im hydrothermalen Quarzbildungsprozeß bei niedrigen Temperaturen. Die Produktfolgen bei verschiedenen Kristallisationsbedingungen werden angegeben und diskutiert.

    Notes: Untersuchungen über die Beständigkeit 0,1 n Chloraminlösungen, die sich über fast 1½ jahre erstreckten, führten zu dem Ergebnis, daß eine solche Lösung bei Verwendung eines reinen Präparates sehr gut haltbar ist und nur in Abständen von zwei bis drei Monaten kontrolliert zu werden braucht.Für Titrationen in saurer Lösung ist Chloramin nur geeignet, wenn die Umsetzung mit dem zu oxydierenden Stoff schnell erfolgt. Sehr glatt lassen sich AsIII und SbIII in saurer Lösung titrieren; geeignete Indikatoren sind p-Äthoxychrysoidin und Brillantcarmoisin. Bei der Bestimmung von Eisen(II)-salzen und Hexacyanoferraten(II) muß Chloraminlösung in geringerem Überschuß zugegeben und dieser mit As2O3-Lösung zurückgemessen werden.

    Description / Table of Contents: On the Modification of Xerogels by Acid TreatmentThe influence of an acid treatment on the texture and structure of silica (xerogel) has been studied. Characteristic changes caused by acid treatment of silica consist of increasing pore-volume decreasing specific surface and of a maximum shift to larger radii of pore distribution in the range of micro and meso pores.A tendency in respect to an increasing degree of order for acid treated silica could be shown.
    Notes: Der Einfluß einer Säurebehandlung auf die Textur und Struktur von Kieselgelen (Xerogelen) wurde untersucht. Die charakteristischen Veränderungen an säurebehandelten Kieselgelen bestehen aus einer Abnahme der spezifischen Oberfläche der Zunahme des spezifischen Porenvolumens und einer Verschiebung der Maxima der Porenradienverteilungskurven  -  im Bereich der Mikro- und Mesoporen  -  zu größeren Porenradien.Eine Tendenz zur Erhöhung des Ordnungsgrades säurebehandelter Kieselgele konnte nachgewiesen werden.
