    Description / Table of Contents: Zusammenfassung Bei 6378 Verkehrsunfällen mit 8931 Verletzten zwischen 1973 und 1989 im Großraum Hannover wurden 3267 PKW-Insassen mit Frakturen registriert. Davon hatten 148 (4,5 %) Personen Frakturen im Fußbereich erlitten. Die Unfalldaten wurden in Hinblick auf Verletzungsentstehung, -art und -ausmaß ausgewertet und die Verletzungsfolgen anhand von Langzeituntersuchungen evaluiert. Bei der Entstehung der Fußfrakturen spielte die Deformierung des Fußraums die wesentliche Rolle. Fahrer und Beifahrer erlitten ähnlich schwere Verletzungen. Bei den 286 Frakturen war der Vorfuß am häufigsten betroffen (45 %), gefolgt von OSG (35 %), Mittelfuß (11 %) und Rückfuß (6 %). Der Anteil der offenen Frakturen betrug 5 %. Die Klassifikation erfolgte nach der „Abbreviated Injury Scale“ (AIS) für die untere Extremität. Die Langzeitfolgen wurden anhand der fußverletzungsbedingten Minderung der Erwerbsfähigkeit (MdE) im Verhältnis zur gesamten MdE abgeschätzt. Diese Auswertung ergab, daß die Fußfrakturen vor allem bei erheblichen Begleitverletzungen bei der Primäruntersuchung oft nicht erkannt oder unterschätzt wurden. Die Langzeitfolgen gingen häufig mit einer erheblichen fußverletzungsbedingten Invalidisierung einher.
    Notes: Summary During 1973 and 1989, 6,378 car accidents with 8,931 injured persons were evaluated in the area of Hannover. 3,267 car drivers and passengers sustained fractures overall and 148 (4,5 %) fractures of the foot. A major role in the ethiology of the foot fractures evolves from the deformation of the foot room. Driver and front seat passenger showed similar injuries. Among the 286 single fractures, the forefoot was affected most often (45 %), followed by ankle (38 %), midfoot (11 %) and hindfoot (6 %). 5 % were open fractures. The long term results were estimated upon the limitation of working ability caused by the foot injury in relation to the entire working ability. The evaluation concludes that the foot fractures especially in combination with other injuries were frequently not recognized within the primary examination and therefore underestimated. The long-term outcome leaded to a high degree of impairment due to foot fractures.

    Description / Table of Contents: Zusammenfassung Bei einer Unfallanalyse von 3.838 gurtgeschützten, angeschnallten PKW-Fahrer/-innen stieg der Anteil der HWS-Distorsionen von unter 10 % 1985 auf über 30 % 1997. Überwiegend traten diese bei frontalen oder mehrfachen Kollisionen auf. Nur bei 15 % der Patienten wurde die Verletzung durch einen reinen Heckanprall ausgelöst. In 23,2 % betrug δv 10 km/h und weniger, was einem sehr leichten Unfall entspricht. Bei frontalen Kollisionen wurde das höchste durchschnittliche δv erreicht; 1.136 der Verletzten wurden angeschrieben, um Dauer und Art eventueller Beschwerden zu ermitteln. Von den 138 Patienten, die den Fragebogen zurücksendeten gaben 121 (88 %) Beschwerden an. Es handelte sich dabei um Schmerzen (74 %), Verspannungen (6 %) und Bewegungseinschränkungen (5 %) im Bereich von Kopf (27 %), Nacken (55 %) und Schulter (8 %). Die Dauer der Beschwerden war am längsten nach mehrfachen Kollisionen und einem Beschwerdebeginn nach mehr als 24 h. Neben einem geringen Einfluß der Begleitverletzungen auf die Beschwerdedauer sind auch die individuelle Konstitution und Schmerzverarbeitung wesentliche Faktoren. Auch bei dieser retrospektiven Untersuchung bestanden erhebliche Schwierigkeiten hinsichtlich der Nachuntersuchung. Zur Lösung dieses Problems sind prospektive Studien mit genau festgelegten Protokollen zur Erfassung von Diagnose, Behandlungsart sowie Beschwerdedauer und -art erforderlich.
    Notes: Summary The analysis of 1,176 whiplash-type neck distortions was sought from a total of 3,838 restrained car driver incident reports. The percentage of these injuries increased from less than 10 % in 1985 to over 30 % in 1997. These occurred mostly with head-on or with multiple collisions, and only in 15 % with pure rear-end collisions. In 23,2 %, δv amounted 10 km/h or less, which corresponds to a very minor crash. The average δv was the highest in the cases of head-on collisions. Letters were sent to the injured to find out about the duration and type of complaints caused by a cervical spine injury. Of the 138 patients who returned the questionnaires, 121 (88 %) indicated that they had or were still suffering from their symptoms. Percentage of various complaints were as follows: pain (74 %), tension (6 %) and stiffness (5 %) in the head (27 %), neck (55 %) and shoulder (8 %). The duration of the complaints was longest after multiple collisions and when the onset of complaints was later than 24 hours after trauma. Women and elderly persons predominated slightly in the group with longer duration of complaints. A correlation between the severity of the accompanying injuries and duration of complaints occurred. Also, with this retrospective study there was considerable difficulties in the lack of adequate follow-up for these patients with less severe injuries. In order to better evaluate this problem, prospective studies are necessary which include documentation of diagnosis, treatment protocols, duration and type of complaints.

    Notes: Summary: The role of visual cues provided by resident wasps on resource choice by yellowjacket and paper wasp foragers was investigated. Large spring queen yellowjackets and small early season yellowjacket foragers (Vespula germanica, Vespula maculifrons, and Vespula vidua) were extracted in hexane to remove odors and posed as though feeding at petri dish feeders bearing daisy-like flower models, equipped with microcapillary feeding tubes, and containing 1:3 honey:water solution. An array of five feeders was presented to foragers at a suburban and a woodland site in Saratoga Springs, New York. The visual cues provided by resident wasps influenced resource choice by approaching social wasp foragers. Vespula germanica, an introduced yellowjacket species that tends to dominate at rich resources, was the only wasp visiting the suburban feeders. Foragers of this species preferentially fed on feeders and flowers with posed wasps and fed most often next to large wasps. Polistes fuscatus foragers at the woodland site similarly preferred to feed on occupied feeders and flowers. Vespula maculifrons and V. consobrina preferentially visited unoccupied feeders. Individual V. maculifrons, V. consobrina and V. vidua foragers that landed on occupied feeders all preferentially visited unoccupied flowers on those feeders. Vespula vidua and V. flavopilosa foragers did not demonstrate a feeder preference based on the presence/absence of posed wasps. Vespula consobrina foragers that visited occupied feeders preferred those occupied by extracted V. maculifrons queens and workers; no other wasps showed species based landing preferences.

    Notes: Summary Whole-cell patch clamp experiments were carried out in rat striatal brain slices. In a subset of striatal neurons (70–80%), NMDA-induced inward currents were inhibited by the adenosine AZA receptor selective agonist CGS 21680. The non-selective adenosine receptor antagonist 8-(p-sulphophenyl)-theophylline and the AZA receptor selective antagonist 8-(3chlorostyryl) caffeine abolished the inhibitory action of CGS 21680. Intracellular GDP-β-S, which is known to prevent G protein-mediated reactions, also eliminated the effect of CGS 21680. Extracellular dibutyryl cAMP, a membrane permeable analogue of cAMP, and intracellular Sp-cAMPS, an activator of cAMP-dependent protein kinases (PKA), both abolished the CGS 21680-induced inhibition. By contrast, Rp-cAMPS and PKI 14–24 amide, two inhibitors of PKA had no effect. Intracellular U-73122 (a phospholipase C inhibitor) and heparin (an inositoltriphosphate antagonist) prevented the effect of CGS 21680. Finally, a more efficient buffering of intracellular Ca2+ by a substitution of EGTA (11 mM) by BAPTA (5.5 mM) acted like U-73122 or heparin. Hence, AZA receptors appear to negatively modulate NMDA receptor channel conductance via the phospholipase C/inositoltriphosphate/Ca2+ pathway rather than the adenylate cyclase/PKA pathway.

    Notes: Abstract We present spectroscopy of the molecular shock in the supernova remnant IC 443. The H2 level populations in IC 443 are nearly identical to Orion Peak 1 (Brand et al. 1988; Parmar et al. 1994) and are consistent with a partially dissociative J-shock. The similarity with Orion suggests the shock processes which dominate the emission in both regions are essentially identical.
