    Description / Table of Contents: Résumé Les réponses antennaires ont été examinées par électroantennogramme aux odeurs de plantes hôtes et non hôtes d'orthoptères Gomphocerinae de comportements alimentaires différents: Bootettix argentatus, monophage sur une dicotylédone, Larrea; Ligurotettix coquilletti, oligophage de dicotylédones; Cibolacris parviceps, polyphage; Chorthippus curtipennis, graminivore. Les types de réponse des quatre espèces étaient très voisins, mais les réponses aux odeurs de Larrea de B. argentatus et L. coquilletti, spécialistes de cette plante, étaient relativement plus fortes. Ces résultats suggèrent une similarité globale considérable dans la composition des populations de récepteurs olfactifs de ces quatre espèces d'orthoptères mais aussi une certaine spécificité pour les odeurs de la plante hôte au niveau antennaire.
    Notes: Abstract Antennal responses to host and non-host odours were recorded, using the electroantennogram technique, from four gomphocerine grasshoppers with different feeding habits: Bootettix argentatus (monophagous on Larrea, a dicotyledonous plant), Ligurotettix coquilletti (oligophagous on dicotyledonous plants), Cibolacris parviceps (polyphagous) and Chorthippus curtipennis (graminivorous). The patterns of responses across the plant odours were similar for all four grasshopper species, but there was a relatively greater response to the odour of Larrea in B. argentatus and L. coquilletti which specialise on this plant. This suggests that there is considerable overall similarity in the make up of the olfactory receptor populations of these four grasshoppers species, but that some specificity for hostplant odour does exist at the antennal level.

    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: Conclusion A number of recent studies have been discussed which provide strong evidence that genetic and immunological factors are important in the pathogenesis of PSC. Current evidence suggests that PSC is, like primary biliary cirrhosis, an immunologically mediated disease [8]. It seems likely that the immunological destruction of the biliary system is triggered in genetically predisposed individuals by viruses or bacteria [8]. The association with ulcerative colitis may be explained by the passage of viral or bacterial organisms across the damaged colonic epithelial barrier into the systemic circulation. Further studies are needed to confirm this attractive hypothesis.

    Notes: Abstract A mail survey was conducted to gain understanding of the agroforestry practices of non-industrial private forest landowners (NIPF) in Washington State, located in the north-western USA. Although NIPF owners control 1.5 million hectares of the state's commercial forestland base, their diversity of forestland uses, land management practices and objectives as land managers are not well understood. Past NIPF surveys and anecdotal information suggest agroforestry is a major use of NIPF lands. We defined agroforestry as a potentially sustainable land use practice combining the deliberate growing of woody perennials with agricultural crops and/or animals. Objectives of this study were to: 1) determine the extent that agroforestry is used by Washington's NIPF owners, 2) develop insight into NIPF owners' motivations for practicing agroforestry, 3) describe the agroforestry practices within three distinct physiographic and agroecological zones in Washington, and 4) determine the agroforestry information needs of NIPF owners. The target population consisted of NIPF owners in 4 counties within each of the three regions. Response to the August 1990 mail survey was 63.5%, yielding 296 useable questionnaires. Fifty-seven percent of all respondents practice agroforestry. Forestland grazing is the most common agroforestry practice (39% of all respondents), followed by windbreaks (34%), harvest of special forest products (12%), livestock enrichment plantings for forage or shelter (7%), orchard grazing (5%), orchard intercropping (2%), and Christmas tree grazing (0.34%). The most frequent motives for owning land were passing land on to children (80%), keeping it natural and income from timber (both 72%). Respondents saw aesthetics (77%), increasing land unit income (74%), and water conservation (70%) as possible advantages of practicing agroforestry. High establishment costs (66%) and livestock damage to trees or crops (64%) were the most frequently selected potential disadvantages to practicing agroforestry. Lack of technical and educational support (67%) and lack of access to livestock/livestock facilities (58%) were disincentives to practicing agroforestry. Landowners are interested in learning more about agroforestry and how agroforestry techniques might be incorporated in their land management tool kit. A significant number of non-industrial private forest land owners in Washington believe that management of forestland, balancing conservation and production goals, can be furthered by suitable agroforestry practices.
