    Notes: Summary Isolated pancreatic islets of normoglycemic sand rats do not respond to 2.5 mM glucose with an enhanced glucagon secretion, which could be observed in normal Wistar rats. Arginine stimulates glucagon release in the presence of 2.5 mM glucose in Wistar rats as well as in sand rats. The secretion pattern is not caused by insulin deficiency since sand rat islets are characterized by an increased insulin secretion rate in vitro. This paradoxical glucagon secretion is not caused by a changed glucagon content but might be related to this species which is able to develop a diabetic syndrome spontaneously.

    Description / Table of Contents: Zusammenfassung Bei 30 bewußtseinsklaren Patienten (24 Männer, 6 Frauen) im Alter von 30–74 Jahren mit ischämischen Großhirnhemisphärenläsionen wurden durchschnittlich 45 Tage nach Krankheitsbeginn polygraphische Nachtschlafregistrierungen durchgeführt. Die Schlaf-EEG-Veränderungen waren gekennzeichnet durch eine Verlängerung der Einschlaf- und Wachzeiten sowie eine Abnahme des tiefen synchronen Schlafes. Korrelationsstatistische Untersuchungen zeigen, daß ältere Patienten längere Wachzeiten haben, ebenso wie Kranke mit hohen komplexen Reaktionszeiten und einer euphorischen Stimmungslage, die als Ausdruck einer hirnorganischen Leistungsbeeinträchtigung interpretiert werden können. Demgegenüber tritt die Schwere des klinisch-neurologischen Syndroms für Art und Schwere der Schlafstörung zurück.
    Notes: Summary In 30 conscious patients (24 men, 6 women) aged 30–74 years suffering from ischemic lesions in the cerebral hemispheres, polygraphic night sleep recordings were performed about 45 days after the beginning of the illness. The alterations in sleep were characterized by a delay in the onset of sleep, prolonged waking periods, and a reduction of deep synchronous sleep. Statistical analysis revealed a relationship between prolonged waking time with higher age as well as with high complex reaction time and euphoric state of mind, which can be considered as a sign of psycho-organic impairment. In contrast thereto, the degree of the neurological symptomatology is of less importance for the kind and extent of the sleep disturbances.
