    Description / Table of Contents: Summary The Stroke Unit concept of the German Neurological Society differs from its precedents in Scandinavia or the United Kingdom. Hallmarks of the German concept are very early onset of diagnosis and treatment, continuous surveillance of vital functions by bedside monitors and specialized care by a multiprofessional team. This comparison of two Stroke Units in Minden and Munich-Harlaching, working according to the new German concept, shows broad similarities in admission intervals, diagnostic procedures, treatment modalities and short term prognosis, with an exceedingly low in-hospital mortality of 3.4–5.6% and a high proportion of patients (64–69%) leaving the hospital with Barthel scores above 70. Ongoing studies will show how this kind of Stroke Unit treatment compares to general wards.
    Notes: Zusammenfassung Das Stroke-unit-Konzept der Deutschen Gesellschaft für Neurologie unterscheidet sich von den Schlaganfallstationen skandinavischer und angloamerikanischer Prägung. Es zielt ab auf eine frühe Aufnahme von Schlaganfallpatienten, die Durchführung einer unmittelbaren Diagnostik und Therapie auf einer spezialisierten Station durch ein multiprofessionelles Team, ein kontinuierliches Monitoring in der akuten Phase und eine früh einsetzende Rehabilitation. Der Vergleich der Daten zweier Schlaganfallstationen an kommunalen Krankenhäusern zeigt eine hohe Übereinstimmung bezüglich der behandelten Patientenzahl, der Diagnostik und Therapien sowie der aufgetretenen Komplikationen während des stationären Aufenthaltes. Es zeigt sich bei den Patienten eine niedrige Krankenhausletalität. Der Datenvergleich dient einer Standortbestimmung und ermöglicht weitere Vergleiche mit ähnlichen oder anderen Konzepten der Akutversorgung von Schlaganfallpatienten.

    Notes: Abstract In the leaves of Coffea arabica L., purine alkaloid formation was estimated by analyzing the theobromine and caffeine content and by measuring the methylation rate of [2-14C]theobromine to [2-14C]caffeine in short-term experiments (6–24 h). At the same time, growth (in terms of dry weight and area), net photosynthesis (NPS), and dark respiration were determined. During leaf development, which was considered to be terminated when NPS was at a maximum (60–80 μmol g-1 s-1) and dark respiration at a minimum (5–7.5 μmol g-1 s-1), the content of theobromine and the velocity of caffeine formation were both found to decrease by a factor of more than 100. The close correlation between the theobromine content and the methylation rate is suspended when purine alkaloid formation is influenced by factors other than leaf development. Among these factors, temperature is the most effective: the velocity of caffeine biosynthesis is increased by raising the temperature and vice versa. Although the plants were well irrigated, a drastic decrease of NPS in the afternoon was observed under all environmental conditions tested. Light saturation was reached between 170–360 μmol m-2 s-1. The temperature optimum of NPS was shown to be very broad (24–33°C)m provided the adaptation time was sufficiently long.
