    Notes: Summary The influence of arachidonic acid (AA) metabolism upon histamine release (HR) from human basophils after stimulation with anti-IgE was studied in 23 atopic and 11 normal individuals. HR occurred significantly faster in atopics than in normals; the total amount of HR after a 40 min incubation period was not significantly different between the two groups. Indomethacin and acetylsalicylic acid (ASA) increased the quantity of HR significantly both in atopics and normals without influencing the time course. Addition of exogenous PGE2 decreased HR; here atopics were more affected than normals 5 and 10 min after challenge with anti-IgE. Production of PGE2 after stimulation with anti-IgE was very low in both groups (in the range of 30–50 pg/106 cells) and often below detection limit (10–20 pg/ml). Addition of glutathione (GSH), a coenzyme of PGE2-isomerase, increased PGE2 production 2 to 5-fold during stimulation with anti-IgE. These data support the idea that arachidonic acid metabolites play an important role in modulating the “releasability” of human basophils. It is suggested that the basophils of atopic individuals may release their histamine faster than normals — perhaps on the basis of a more slowly acting endogenous feedback mechanism by PGE2. Both phenomena support the idea of an altered “releasability” of basophils from atopics compared to normals.

    Description / Table of Contents: Zusammenfassung Zwei Gruppen von Hunden wurden elf Tage lang mit 20 mg/kg 131-I-markiertem Pferde-anti-human-Lymphozyten-Globulin bzw. Normal-Pferde-Gammaglobulin i.v. behandelt. Pferde-anti-human-Lymphozyten-Globulin wurde signifikant schneller eliminiert als Normal-Pferde-Gammaglobulin. Im Gegensatz zu dem kontinuierlichen Anstieg der Serum-Radioaktivität unter Normal-Pferde-Gammaglobulin-Behandlung war in der Pferde-anti-human-Lymphozyten-Globulin-Gruppe ab dem 5. Tag eine Plateaubildung zu beobachten. Zum Behandlungsende betrug die Serumkonzentration des xenogenen Proteins 165 ± 8 mg/1 in der Pferde-anti-human-Lymphozyten-Globulin- und 498 ± 15 mg/1 in der Normal-Pferde-Gammaglobulin-Gruppe. Die Pferde-anti-human-Lymphozyten-Globulin-behandelten Tiere zeigten einen signifikant höheren Anstieg agglutinierender Antikörper gegen Pferde-Erythrozyten als Normal-Pferde-Gammaglobulin-behandelte Tiere. Diese starke Immunogenizität von antilymphozytärem Pferde-Gammaglobulin muß bei der Applikation von Pferde-anti-human-Lymphozyten-Globulin berücksichtigt werden.
    Notes: Summary Two groups of dogs received daily intravenous doses of 20 mg/kg 131-I-labelled horse-anti-dog lymphcyte globulin or normal horse gammaglobulin respectively over a period of 11 days. Horse-anti-dog lymphocyte globulin showed a significantly higher eleimination rate than normal horse gammaglobulin. In contrary to the continuous increase in serum radioactivity during normal horse gammaglobulin treatment, there was a plateau after the 5th day in the horse-anti-dog lymphocyte globulin group. The xenogeneic protein concentration, measured with the single radial immunodiffusion technique, at the end of treatment was 165 ± 8 mg/1 in the horse-anti-dog lymphocyte globulin, compared to 498 ± 15 mg/1 in the normal horse gammaglobulin group. After treatment horse-anti-dog-lymphcyte globulin treated animals showed a significantly higher increase in active hemagglutination titer against horse erythrocytes with an average of 2−8.
