    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 In anaesthetized cats, anterior and posterior hypothalamic areas were simultaneously superfused with artificial CSF using two push-pull cannulae. The rates of release of endogenous catecholamines were determined in the superfusates which were continuously collected in periods of 10 seconds. In both areas, the rate of release of dopamine was higher than the rates of release of noradrenaline and adrenaline. Electrical stimulation of the splanchnic nerve elicited a rise in the arterial blood pressure and increased the rates of release of noradrenaline, adrenaline and dopamine in the anterior hypothalamic area. The rates of release of the catecholamines in the posterior hypothalamic area were not influenced by the pressor response to stimulation of the splanchnic nerve. Transection of the brain caudal to the hypothalamus reduced the rates of release of the catecholamines in the anterior hypothalamus and abolished the releasing effect of the stimulation of the splanchnic nerve. The results indicate that acute rise in blood pressure activates catecholamine cell bodies in the lower brain stem, which in turn stimulate the anterior hypothalamus to counteract the pressor response.
