    Notes: Summary The effect of a long-term administration of furosemide (2×30 mg/day for 3 weeks) on platelet α2-adrenoceptor density and the fraction of high-affinity binding sites, as well as on platelet aggregation induced by adrenaline and ADP, was studied ex vivo in 8 normotensive volunteers. For comparison the in vitro effect of furosemide on platelet aggregation was also evaluated. Furosemide decreased α2-adrenoceptor-density (P〈0.01) and the fraction of high-affinity binding sites (P〈0.05). Adrenaline-induced platelet aggregation was not altered ex vivo and in vitro. Furosemide inhibited ADP-induced platelet aggregation ex vivo (P〈0.05) and in parallel in vitro (P〈0.01) in a dose-dependent manner. The reduction of the density of α2-adrenoceptors in the high affinity state may be of functional importance for the hemodynamic effects of furosemide. The inhibitory effect of furosemide on ADP-induced platelet aggregation ex vivo and in vitro, which is not related to the effects on adrenoceptors, seems to involve direct effects of furosemide on platelet function. It remains to be seen whether the latter effect is of clinical importance.

    Description / Table of Contents: Zusammenfassung Ein 63jähriger Alkoholiker stürzt in betrunkenem Zustand im Treppenhaus. Auf der Rettungsteile ist der Mann schläfrig aber bei Bewußtsein; es werden neben der Alkoholisierung keine gravierenden Verletzungen festgestellt, Röntgenaufnahmen des Schädels verwackeln. Übernachtung in Polizeigewahrsam (GeSa), am nächsten Morgen zu Fuß nach Hause, dort über 2 Tage Eintrübung, Nausea, Erbrechen. $$2{\raise0.5ex\hbox{$\scriptstyle 1$}\kern-0.1em/\kern-0.15em\lower0.25ex\hbox{$\scriptstyle 2$}}$$ Tage nach dem Sturz von Ehefrau leblos im Bett aufgefunden. Obduktion: Oberfl. Schürfung Kopfhaut re. parietal, darunter Blutungen in der Galea und re. M. temp.; ausgedehntes Bruchsystem re. Parietalregion. Ein Ast der re. A. cerebri media war durch einen Riß der Dura ziehend zwischen Cortex und einer der Frakturlinien aufgespannt. Intracranielle Blutungen konnten ebenso wie Verletzungen der Arterie selbst nicht beobachtet werden. Der Fall ist erneut ein Indiz für die großen Relativbewegungen zwischen Gehirn und Schädel bei derartigen Traumen.
    Notes: Summary A 63-year-old drunken man fell and hit his head on the ground. Apart from symptoms of alcoholisation no signs of severe injuries were found. The man died $$2{\raise0.5ex\hbox{$\scriptstyle 1$}\kern-0.1em/\kern-0.15em\lower0.25ex\hbox{$\scriptstyle 2$}}$$ days after the accident. The autopsy revealed a huge fracture system in the right parietal region. A branch of the medial cerebral artery was stretched between the cortex and one of the fracture lines, passing through a tear in the dura. Characteristics of this case were that no larger hemorrhage was found and the artery which was torn from the cortex showed no lesions. The case also indicates the immense relative movements between skull and brain which occur during such trauma.
