    Description / Table of Contents: Zusammenfassung Zur Differenzierung verschiedener Formen von Kleinhirnatrophien wurden axiale Computer-Tomogramme (CT) des Schädels bei 69 Patienten durchgeführt. Die größten Gruppen umfassen 45 Patienten mit Friedreichscher Ataxie und 14 Patienten mit idiopathischer oder symptomatischer Kleinhirnatrophie. Bei 4 Patienten konnte Morbus Nonne-Pierre Marie, einmal olivo-ponto-cerebelläre Atrophie diagnostiziert werden. Es wird gezeigt, daß das CT eine wesentliche Hilfe zur Unterscheidung der verschiedenen Krankheitsgruppen intra vitam darstellt und darüber hinaus eine recht sichere Differenzierung gegenüber anderen Krankheiten erlaubt. Die Atrophien sind unterschiedlich und zum Teil charakteristisch verteilt. Schwere Formen von Friedreichscher Ataxie gehen oft mit Atrophie von Oberwurm und Paravermis einher, sind also nicht rein spinal lokalisiert, was methodisch bedingt auch bei Sektionen oft makroskopisch nicht wahrzunehmen ist.
    Notes: Summary Cranial computerized tomography was carried out in 69 patients with cerebellar ataxia (45 with Friedreich's ataxia, 4 with Marie's spastic ataxia, 14 with cerebellar atrophy, and one patient with olivo-pontocerebellar atrophy). In CT scans cerebellar atrophy is found to be of various localisation and partially of characteristic distribution. CT, therefore, greatly helps to distinguish different types of cerebellar and spino-cerebellar atrophy and also distinguishes separate cerebellar atrophy of various origin from other diseases like multiple sclerosis.

    Description / Table of Contents: Zusammenfassung Um zu untersuchen, ob die Gabe von Phosphatidylcholin, die den zentralnervösen Azetylcholingehalt erhöht, einen Einfluß auf die Neurotransmitter Glutamat und GABA hat, wurde 17 von 32 Ratten über 14 Tage 1,5g/kg Lethicon® pro die peroral gegeben. Die fluorometrische Messung der Konzentrationen von Glutamat und GABA in frontalem Cortex, Striatum, Nigra, Kleinhirnrinde sowie von Glutamat im Liquor cerebrospinalis ließ keine signifikanten Unterschiede gegenüber Kontrolltieren erkennen. Nach zweiwöchiger Gabe von Phosphatidylcholin konnte keine zentralnervöse Interaktion des cholinergen Systems mit den Neurotransmittern Glutamat und GABA nachgewiesen werden.
    Notes: Summary Phosphatidylcholine increases CNS concentrations of acetylcholine. In rats we investigated whether or not phosphatidylcholine also influences the neurotransmitters glutamate and GABA. In 17 rats 1.5g/kg Lethicon perorally was administered daily for 2 weeks, 15 rats served as controls. In tissue from frontal cortex, striatum, substantia nigra, cerebellar cortex no significant differences between treated and untreated animals were found in glutamate or GABA concentrations. A central nervous interaction between the cholinergic system and the neurotransmitters glutamate and GABA, therefore, could not be demonstrated after 2 weeks of phosphatidylcholine intake.

    Notes: The 6,6′-disubstituted 2,2′-bipyridines and oligo(bipyridines) are often used as ligands in supramolecular chemistry; however, their range of application has been limited due to the lack of unsymmetrically functionalized compounds and their poor solubility. We describe herein a new generation of specially designed unsymmetrical bipyridine building blocks possessing different protecting groups for the hydroxy functionality and reasonable solubility behavior. These molecules permit the synthesis of a wide range of functionalized oligo(bipyridines) with new potential applications in supramolecular chemistry and materials science. As initial examples, we present the synthesis of mono- and bis-functionalized bis- and tris-2,2′-biypridines.
