    Notes: Summary The sera of 30 patients suffering from schizophrenia (DSM III) and 30 neurological controls were tested for antibrain antibodies in a blind indirect immunofluorescence assay. We found IgG- and IgM-binding in the sera of 22 patients, but only 4 out of the 30 age- and sex-matched controls. The binding was mainly directed to neurons from the frontal cortex and septal area, areas, which are regarded as important in the development of schizophrenic illness. These preliminary data are presented, to encourage other immunological studies in schizophrenia research.

    Notes: Abstract In advanced stages of Parkinson’s disease problems of speech, mobility and balance occur with a high frequency. Although the symptoms of the disease can be treated by specific and individual pharmacotherapy, some of the severe symptoms such as freezing, falls, unsteadiness, and dysarthria persist. To evaluate the potential use of additional therapies, a diagnosis of all current symptoms must be performed; afterwards a specific individual treatment can be decided by the therapist based on objective data. Only if the initial evaluations of a new therapy show improvement, will such therapies be subjected to long-term evaluation, which should be also performed by the patient. This contribution presents examples of a useful prediagnosis and of the evaluation of the conventional physiotherapy. Also, two new methods are evaluated as additional therapies: low-frequency muscle stimulation and magnetic pulse therapy. A thorough symptomatic diagnostic view, specifically directed additional therapy and the careful evaluation of the use of therapies provide the only meaningful treatment of Parkinson’s disease.

    Notes: Summary T-lymphocyte subpopulations were examined in the peripheral blood of 30 acute schizophrenic patients and compared with 30 age- and sex-matched patients with non-inflammatory neurological diseases. Significant increases in the numbers of Pan-T and T-helper cells were found in schizophrenic patients compared to the controls. The interindividual variability of values in the group of schizophrenic patients was greater than in the group of neurological patients.

    Description / Table of Contents: Ultrafeine ZrO2 - Pulver durch Laserverdampfung: Herstellung und EigenschaftenUltrafeine oxidische Pulver werden durch Co2-Laserverdampfung aus grobem ZrO2-Pulver oder kompakten ZrO2-Stangen hergestellt.Die 10.6 μm-Strahlung im Leistungsbereich von 1 bis 4 kW wird durch einen quergeströmten CO2-Laser erzeugt, der in cw-und Pw-Betrieb arbeitet.Die Verdampfungsrate ist abhängig von der relativen Lage der Fokalebene zur Oberfläche des ZrO2-Pulvers, der Laserintensität und der eingekoppelten Energie.Bei einer Laserintensität von 4.2 · 105 Wcm-2 erreicht man eine optimale Verdampfungsrate von 130 g · h-1 (cw-Betrieb des Lasers).Das hergestellte Pulver besteht aus sphärischen Partikeln; deren Durchmesser variiert im Bereich von 5 bis 200 nm und kann durch die Verfahrensparameter beeinflußt werden. Die spezifische Oberfläche ist einstellbar von 10 bis 30 m2 · g-1.Das Pulver aus unstabilisiertem Zirkonium besitzt einen sehr hohen Anteil tetragonaler Phase. Im Fall von chemisch stabilisiertem Zirkonium kann sich die Zusammensetzung während des Verdampfungsprozesses und der Rekondensation ändern.
    Notes: Ultrafine oxide powders were produced by CO2 laser evaporation of coarse ZrO2 powder or compact stabilized ZrO2 materialThe 10.6μm radiation in the power range 1-4kW was generated by a transversal flow Co2 laser which can oscillate in cw and pw operationThe vaporization rate depends on the relative position of the focal plane to the surface of the ZrO2 powder, the laser intensity and the supplied energy input.At a laser intensity of 4.2 · 105 Wcm-2 the optimum vaporization rate is 130 g · h-1 (cw-operation of the laser).The produced powders consist of spherical particles; their diameters vary in the range from 5 to 200 nm can be controlled by the process conditions. The surface area (BET) is adjustable from 10 to 30 m2 · g-1.The powders of unstabilized zirconia show an unusual high content of the tetragonal phase. In case of chemically stabilized zirconia the composition can change during the process of evaporation and recondensation.

    Notes: The dependence of depth resolution Δz/z on the sputtering angle θ is investigated for three sputter-deposited films: Cr (bee), SiNx (amorphous) and FeCoTb (amorphous). The depth resolution for the Cr system exhibits two maxima at θ = 35° and 45°. These are characteristic for bee textured material but different from fee textured material. The amorphous films show a very weak dependence, if any, owing to the absence of crystallites and crystalline texture. These results are in accordance with channeling theory.

    Notes: In an NiFe/Ta system, interface widths (Δz) are compared for sputter profiles with stationary and rotating sample holder (Zalar rotation). For low sputter angles, the Zalar rotation brings considerable improvements in Δz. For higher sputter angles, the improvement available through Zalar rotation vanishes as self-shadowing due to crystallites with less favorable orientation becomes the dominating rate mechanism. The improvement is further reduced for thinner films much below 1000 Å. For low sputter energies and films 125 Å thick, Zalar rotation has no influence. The limit of depth resolution was 30 Å, which resulted from the substrate-induced roughness of the NiFe/Ta interface. The interface width's maximum near 30° for stationary sputter etching is characteristic of sputter-deposited fcc films.
