    Description / Table of Contents: Zusammenfassung Bei einem 55 Jahre alten Patienten mit bekanntem Bronchialcarcinom entwickelten sich dystone Bewegungsstörungen des rechten Armes, Schluckbeschwerden und eine progrediente Kieferklemme. Hinzu kamen horizontale Blickparese, ataktische Störungen und Verminderung der Vibrationsempfindung. Vor dem Tode bestand neben kompletter Ophthalmoplegie und nahezu vollständiger Kiefersperre eine zentrale Hypoventilation. Die neuropathologische Untersuchung zeigte das Vorliegen von Hirnstammencephalitis, Ganglioradikuloneuritis, Hinterstrangdegeneration des Rückenmarkes und geringem Purkinje-Zell-Ausfall im Kleinhirn. Die Veränderungen werden als kombiniertes paraneoplastisches Syndrom erklärt. Die klinisch imponierenden Symptome der zentralen Hypoventilation und dystonen Bewegungsstörung werden beschrieben. Mögliche morphologische Korrelate werden diskutiert.
    Notes: Summary A 55-year-old patient with known lung cancer was admitted with dystonia of the right arm, lockjaw, horizontal gaze palsy and dysphagia. Prior to death total ophthalmoplegia and central hypoventilation developed. Postmortem examination showed brainstem encephalitis, gangioradiculoneuritis, posterior column degeneration and loss of cerebellar Purkinje cells. These changes are considered to constitute a combined paraneoplastic syndrome. The dystonic movement disorder and central hypoventilation and their possible morphologic correlates are discussed.

    Notes: Summary The posterior hypothalamus of anaesthetized cats was superfused with a push-pull cannula and the release of the endogenous catecholamines noradrenaline, adrenaline and dopamine was determined in the superfusate. The rate of release of the three catecholamines followed an ultradian rhythm, the time interval between two adjacent phases of high rate of release being about 70 min. Pretreatment of the animals with reserpine decreased the levels of catecholamines in the hypothalamus and rest of the brain and reduced their rate of release into the superfusate. Hypothalamic superfusion with superfusing fluid of high concentration of potassium and low concentration of sodium enhanced the rate of release of noradrenaline and adrenaline; this effect was abolished when the hypothalamus was superfused with calcium-free solution. Electrical stimulation of the locus coeruleus ipsilateral to the superfused hypothalamus increased the release of noradrenaline and adrenaline, stimulation of the contralateral locus coeruleus enhanced the release of noradrenaline, adrenaline and dopamine. In both cases, the rate of release of adrenaline was enhanced to a lesser extent than the rate of release of noradrenaline. The release of noradrenaline and adrenaline was increased to a higher extent on stimulation of the ipsilateral locus coeruleus than on stimulation of the contralateral one.
