    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 A randomized study of 6 ventilatory modes was made in 7 piglets with normal lungs. Using a Servo HFV 970 (prototype system) and a Servo ventilator 900 C the ventilatory modes examined were as follows: SV-20V, i.e. volume-controlled intermittent positive-pressure ventilation (IPPV); SV-20VIosc, i.e. volume-controlled ventilation (IPPV) with superimposed inspiratory oscillations; and SV-20VEf, i.e. volume-controlled ventilation (IPPV) with expiratory flush of fresh gas; HFV-60 denotes low-compressive high-frequency positive-pressure ventilation (HFPPV) and HVF-20 denotes low-compressive volume-controlled intermittent positive-pressure ventilation; and SV-20P denotes pressure-controlled intermittent positive-pressure ventilation. With all modes of ventilation a PEEP of 7.5 cm H2O was used. In the abbreviations used, the number denotes the ventilatory frequency in breaths per minute (bpm). HFV indicates that all gas was delivered via the HFV 970 unit. The ventilatory modes described above were applied randomly for at least 30 min, aiming for a normoventilatory steady state. The HFV-60 and the HFV-20 modes gave lower peak airway pressures, 12–13 cm H2O compared to approximately 17 cm H2O for the other ventilatory modes. Also the mean airway pressures were lower with the HFV modes 8–9 cm H2O compared to 11–14 cm H2O for the other modes. The gas distibution was evaluated by N2 washout and a modified lung clearance index. All modes showed N2 wash-out according to a two-compartment model. The SV-20P mode had the fastest wash-out, but the HFV-60 and HFV-20 ventilatory modes also showed a faster N2 wash-out than the others. Regarding the lung clearance index, the SV-20P, HFV-60 and HFV-20 modes showed better indices than the other modes. No relationship was found between the ventilatory mode and extravascular lung water, and there were no differences in the hemodynamic variables.

    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.

    Notes: Zusammenfassung Der Grippevirus-Aluminiumhydroxyd-Adsorbatimpfstoff ruft nach der Injektion die Bildung einer bindegewebigen Kapsel um die injizierte Impfstoffmasse hervor. Dieses Depot kann entfernt werden, der Depotinhalt kann erneut zur Immunisierung von Versuchstieren dienen. Die Entnahme des Depots erlaubt es, ein Urteil über die Leistungsfähigkeit des Impfstoffes abzugeben und Termine festzusetzen, bis zu denen eine Entnahme des Depots ohne Unterbrechung der Antikörperbildung erfolgen kann.

    Meerschweinchen als Typhusbakterienausscheider (1953)

    Notes: Zusammenfassung Es gelingt, nach Infektion der Gallenblase von Meerschweinchen den Zustand eines Typhusbakterienausscheidertums herzustellen. Da der Erfolg von individuellen Faktoren abhängig ist, wird empfohlen, durch häufige Prüfung der Ausscheidung in Kot und Urin und im Widal die Meerschweinchen erst 30 Tage nach der Infektion für chemotherapeutische Versuche zu bestimmen. Entscheidend sind die Typhusbakterien-Kontrollen der Organe nach der Sektion. Zur Erprobung von chemotherapeutischen Mitteln werden Experimente mit Typhusbakterien ausscheidenden Meerschweinchen angeraten.

    Notes: Abstract Nano-crystalline zirconia particles, prepared by laser evaporation, were analyzed by electron microscopy and X-ray diffraction. The volume part of particles of the tetragonal modification comes up to 90%, although the sizes of the majority of the particles lie significantly above the equilibrium size of the transformation tetragonal → monoclinic. First interpretations are given.

    Classification of electrode glasses including structural parameters (1994)

    Notes: Abstract Cluster Analysis has been shown to be partially suitable for the classification of glasses. The expansion of the clusters on the Seger's diagram allows an investigation of the influence of the different glass components. Variation of the SiO2 content results in a smaller change of properties than variation of the Na2O/RO relationship. Principal Component Analysis is convenient for showing correlations between the composition of the examined glasses, the glass structure parameters, and the different electrode properties.

    Remote auscultatory patient monitoring during magnetic resonance imaging (1992)
    Springer
    Journal of clinical monitoring and computing 8 (1992), S. 37-43

    Notes: Abstract A system for patient monitoring during magnetic resonance imaging (MRI) is described. The system is based on remote auscultation of heart sounds and respiratory sounds using specially developed pickup heads that are positioned on the precordium or at the nostrils and connected to microphones via polymer tubing. The microphones operate in a differential mode outside the strong magnetic field to reduce various sources of interference from the MRI equipment. After amplification, the signal is transmitted as infrared light to a small, battery-operated receiver and a headphone set. Thus, the patient can be simultaneously auscultated both inside and outside the shielded MRI room by infrared transmission through a metal mesh window. Bench tests of the system show that common mode acoustic noise is suppressed by approximately 30 dB in the frequency region of interest (100–1,000 Hz), and that polymer tubing having a diameter of approximately 2 mm can be used for efficient sound transmission. Recordings in situ show satisfactory detection of both heart sounds and respiratory sounds, although the signal is somewhat masked by noise during imaging. A clinical test incorporating 17 sedated or anesthetized patients was also performed. In all but four cases, the quality of the breath and heart sounds was regarded as acceptable or better.
