    Description / Table of Contents: Zusammenfassung Der Fall eines 26 Jahre alten Mannes wird beschrieben, welcher nach einer Episode von Traumen eine tödliche intraventrikuläre Hirnblutung erlitt. Bei der Obduktion wurde nach dem ersten Eindruck eine traumatische Subarachnoidalblutung vermutet, und die anfängliche Untersuchung war daher auf die Strukturen des Halses und auf die Vertebralarterien gerichtet, jedoch mit negativen Resultaten. Die Sektion des fixierten Gehirns zeigte eine massive intraventrikuläre Blutung mit sekundärer Beteiligung des Subarachnoidalraums und Ausbreitung in das Hirnparenchym. Keine Blutungsquellen oder natürliche Erkrankungen der Hirngefäße konnten gefunden werden. Die praktischen Aspekte der Diagnose und der vorsichtige Ansatz, welcher notwendig ist, um Subarachnoidalblutungen zu interpretieren, werden betont. Die Bedeutung der intraventrikulären Blutung nach Trauma ist mit der Einführung der Computertomographie offensichtlicher geworden. Die Implikationen dieses und ähnlicher Fälle werden bedacht.
    Notes: Summary A case of a 26-year-old man who suffered a fatal intraventricular cerebral haemorrhage following an episode of trauma is described. The initial appearance at necropsy suggested a traumatic subarachnoid haemorrhage and initial investigation was directed towards the anterior neck structures and the vertebral arteries with negative results. Dissection of the fixed brain showed a massive intraventricular bleed with secondary involvement of the subarachnoid space and dissection into the cerebral parenchyma. No bleeding points or natural disease of the cerebral vessels could be identified. The practical aspects of diagnosis and the cautious approach necessary in interpreting subarachnoid bleeding is emphasised. The significance of intraventricular haemorrhage following trauma has become more apparent with the advent of computed tomographic scanning. The implications for this and similar cases are considered.

    Notes: Abstract The host-selection behavior of three species of grasshopper feeding on creosote bush,Larrea tridentata, in southern California was investigated. The species wereBootettix argentatus, which is monophagous;Ligurotettix coquilletti, oligophagous; andCibolacris parviceps, polyphagous. The monophagous species is stimulated to bite by nordihydroguaiaretic acid (NDGA), a compound that is characteristic of the host plant and that may comprise up to 10% of the dry weight of the leaf. Host specificity ofB. argentatus is enhanced by deterrent responses to compounds present in the surface waxes of all non-host-plant species. Both the oligophagous and polyphagous species are deterred by NDGA at naturally occurring concentrations. Their association withLarrea is probably based on tolerance of the plant chemicals rather than on dependence on specific chemicals. Factors other than the chemistry of the plant probably also contribute to the specificity ofB. argentatus andL. coquilletti.
