    Notizen: The in vitro effect of levamisole (LMS) on lymphocyte, neutrophil, basophil and platelet function was investigated in patients with severe atopic dermatitis and hyper-immunoglobulinaemia E. Lymphocyte stimulation by several concentrations of PHA, con A and PWM, polymorphonuclear leukocyte chemotaxis and basophil histamine release were unaffected by LMS (10 μg/ml). Platelet serotonin release induced by iodipamide was decreased in patient and control groups by LMS but release induced by methacholine, epinephrine and thrombin was not.

    Notizen: Abstract The Perkin-Elmer Zeeman/5000 Atomic Absorption Spectrometer is only able to perform a calibration with three single standards or a one-point standard addition. The accuracy and precision of these methods are inappropriate in ETA-AAS, a computer-based data management is essential. A software package for calibration and evaluation was developed using curve fitting by linear regression based on a leastsquares fit when absorbances were transformed by the Baule-Mitscherlich function. The total analytical range could be covered by this method whether peak area or peak height values were fitted. The maximum absorbance levels could be calculated, as well. Absorbance signals were collected and stored by the “HGA-graphics” software (modified by Perkin-Elmer Nederland B. V.). The “Pecowriter” software was used for identifying data and file manipulations. The results of the calibration and evaluation can be stored on disk and/or printed. Calibration curves can be plotted on hardcopy output. The “Limit of Detection” and the “Characteristic Mass” can be calculated. The use of the CALIBRATION program is demonstrated by the calibration curves for the determination of Pb, Cd, As, Se, Cr, Al, Cu and Ni using mostly STPF-conditions. The performance of the method evaluated by the root mean square percent deviation of the fit is equal to the traditional curve-fitting function as well as to rational or quadratic functions. The use of the EVALUATION program is demonstrated by the results of the direct determination of lead in mineral waters.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Die derzeit gebräuchlichen i.v. Gammaglobuline (GG) zerfallen im wesentlichen in zwei Gruppen: Gespaltene und ungespaltene Produkte. Gespaltene GG erhält man durch Pepsin- oder Plasmin-Behandlung, ungespaltene durchβ-Propiolacton-Stabilisierung, Säure-pH-4-Behandlung oder Polyäthylenglykol-Hydroxyäthylstärke-(PEG/HÄS)-Fällung. Die einzelnen Präparate unterscheiden sich in ihrer biologischen Aktivität (bestimmte Funktionen der Komplementaktivierung und Opsonisierung sind an die Fc-Struktur gebunden) sowie im Eliminationsverhalten (ungespaltene GG haben längere intra- und extravasale Halbwertszeiten). Während die Wirkung von GG in tierexperimentellen Studien gesichert erscheint, stehen für die meisten klinischen Indikationen kontrollierte Studien noch aus. Eine prospektive Studie an chirurgischen Risikopatienten ergab, daß die prophylaktische Gabe von hohen Dosen eines 7 S-GG die Häufigkeit septischer Komplikationen im post-operative Verlauf zu senken vermochte. Die Zukunft der GG-Therapie scheint in der Entwicklung eines größeren Spektrums von Hyperimmunglobulinen zu liegen.
    Notizen: Summary The presently available i.v. gammaglobulines (GG) can be classified into two groups: Degraded and intact GG. Degraded GG are produced by pepsin or plasmin digestion. Intact GG are obtained byβ-propiolactone treatment, acidification at pH 4 or precipitation with polyethylenglycol-hydroxyethylstarch (PEG/HES). The various products have different characteristics with regard to their biological activity (certain functions of complement activation and opsonization are connected with the Fc structure) as well as their elimination (intact GG have longer intra-and extravasal half-life times). While their is no doubt about an effect of GG in animal experiments, little controlled studies have been done for most of the clinical indications. One controlled prospective study showed that in surgical high risk patients the frequency of septic complications can be reduced by prophylactic application of high doses of 7 S-GG. For the future, the development of a broad spectrum of hyperimmunoglobulines seems desirable.
