    Notes: Summary A 32-year-old, HIV-positive homosexual with Kaposi's sarcoma was given subcutaneous interferon-A (IFN) for two- and a-half months. The patient complained of ocular symptoms (ptosis of the left eyelid and intermittent diplopia) after the application of IFN-A. These symptoms persisted for the period of treatment and subsided after therapy was stopped. However after IFN-A was resumed, ptosis and diplopia recurred. Intensive serological and neurological diagnostic investigations failed to present any reason for these ocular symptoms. From data and the clinical appearance we suppose that in this case the patient suffered a pseudo-myasthenic reaction to IFN-A.

    Notes: Summary Treatment of neuropsychiatric symptoms with AZT (Azidothymidine) seems to be effective in many AIDS patients. In earlier studies, 204 of 525 patients treated with AZT showed neuropsychiatric improvement. In this presentation, two patients with affective disorder and dementia are described. Both patients showed remarkable improvement of their severe psychiatric symptoms after AZT. The authors recommend treatment of AIDS-associated dementia and psychoorganic symptoms with AZT.

    Description / Table of Contents: Amine-Boranes as Precursors for Boron CarbonitrideAmine-Boranes have been investigated with respect to their thermal decomposition in the temperature range from rom temperature to 1050°C. The phase transformation of the pyrolytic residue derived from BH3 · C5H5N subsequently heat-treated at temperatures up to 2200°C was studied. The progress of the pyrolysis has been detected by thermal analysis (TGA) and mass spectroscopy. Chemical analysis and ESCA measurements show that the pyrolytic products are single-phase boron carbonitride (BxCyNz) which can be described as a boron and nitrogen containing pyrolytic carbon. This is also supported by means of analytical electron microscopy. Hot pressing of the pyridine-borane-derived BxCyNz at 1800°C and a pressure of 190 MPa yields whiskerlike crystals whose d-values are in accordance with that of BN and/or graphite.
    Notes: Die thermische Zersetzung von Amin-Boranen im Temperaturintervall von Raumtemperatur bis 1050°C sowie die Phasenumwandlung des aus BH3 · C5H5N erhaltenen Rückstands bei Temperaturen bis 2200°C wird untersucht. Der Pyrolyseverlauf wird thermogravimetrisch und massenspektroskopisch verfolgt. Nach elementaranalytischen und photoelektronenspektroskopischen (ESCA) Ergebnissen handelt es sich bei den Zersetzungsprodukten um einphasiges Borcarbidnitrid (BxCyNz), einem Bor und Stickstoff enthaltenden pyrolytischen Kohlenstoff. Dies wird auch durch die analytische Elektronenspektroskopie bestätigt. Durch nachfolgende „Auslagerung“ des aus Pyridin-Boran erhaltenen amorphen BxCyNz in einer Heißpresse bei 1800°C und 190 MPa Druck werden whiskerförmige Kristalle, deren d-Werte auf die Bildung von BN und/oder Graphit hinweisen, erhalten.
