    Description / Table of Contents: Zusammenfassung Jede Streßreaktion führt zu einer hormonell bedingten, gesteigerten Fettsäurenmobilisation, deren Ausmaß als Parameter für den Schweregrad eines Aggressionsgeschehens angesehen werden kann. An 15 Patienten mit idiopathischer Trigeminusneuralgie, die sich einer operativen Therapie in Neurolepthypalgesie unterzogen, wurde die Frage nach quantitativen und qualitativen Änderungen im Fettsäurenkonzentrationsmuster unter der Operation geprüft. Im Gegensatz zu einigen Angaben in der Literatur fanden wir, daß die Erhöhung der Gesamtfettsäurenkonzentration auf einer gleichsinnigen Zunahme aller Einzelsäuren beruht. Durch praeoperative Gabe des Betarezeptorenblockers Pindolol ließ sich das Ausmaß des Fettsäurenanstiegs deutlich mindern, ohne daß es zu einer qualitativen Verschiebung einzelner Fettsäuren kam.
    Notes: Summary Every stress reaction leads to an increased, hormonelly induced mobilisation of fatty acids, the extent of which may be considered as a parameter of the aggression mechanism. In 15 patients with idiopathic trigeminal neuralgia, who were operated under neurolepthypalgesia, the problem of quantitative alterations of the concentration pattern of fatty acids was investigated during the operation. In contrast to some reports of the literature, the increase of the concentration of total fatty acids was due to corresponding increases of all individual fatty acids. By preoperative administration of the beta-adrenergic blocking agent Pindolol the increase of fatty acids was reduced without a qualitative shifting of individual fatty acids.

    Notes: Abstract In this paper an array acousto-optical spectrometer (AOS) with four 1 GHz bands and a frequency channel spacing of 1 MHz is presented. A discussion about the requirements which have to be fulfilled by the presented instrument for applications in radio astronomy is given as well as e detailed description of the optical design. Remarkable test results have been achieved such as an Allan-Variance minimum time of about 1000 s, identical noise performance, and identical frequency calibration of all bands. The reproducibility of measurements has been demonstrated by tests with CH3CN, using an absorption cell. The question of the maximum number of bands per array AOS is discussed. Although it may seem promising to increase the number of bands per optical unit to e.g. eight or more instead of four, a strong limitation has been found due to the increasing r.f. power level on the Bragg cell which affects the baselines of the spectra.
