    Description / Table of Contents: Zusammenfassung Diein vivo-Wirksamkeit von Kaninchenantiserum gegen Rattenmakrophagen (KARMS) bzw. Rattenthymuslymphocyten (KARTS) wurde nach serologisch erschöpfender Absorption mit Rattenthymuslymphocyten bzw.-makrophagen untersucht. Beide Antiseren waren im Gegensatz zu Kaninchennormalserum stark, jedoch völlig unterschiedlich wirksam. Im peripheren Blut erzeugte KARMS eine selektive 〈 24 Std anhaltende Monocytopenie; KARTS erzeugte eine entsprechende Lymphopenie. Phagocytierende Leberzellen zeigten 3 Std nach i.v. Seruminjektion folgende Veränderungen: KARMS reduzierte die Zahl Kupfferscher Sternzellen, steigerte jedoch stark die Aktivität der vorhandenen, die Monocyten und Granulocyten phagocytierten. KARTS induzierte bei normaler Zahl von Kupffer-Zellen mittlere Aktivitätssteigerung und Phagocytose von Lymphocyten. Diese Befunde werden diskutiert im Rahmen unserer Untersuchungsreihe über Reaktionsspezifitäten heterologer Antiseren nach erschöpfenden Absorptionen mit verschiedenen, kreuzreagierenden Zellarten.
    Notes: Summary In vivo effects of rabbit antisera against rat macrophages (AMS) resp. rat thymic lymphocytes (ALS) were studied after their serologically exhaustive absorption with rat lymphocytes resp. macrophages. In contrast to normal rabbit serum both antisera were strongly, but differently active. In peripheral blood, AMS induced a selective monocytopenia of 〈 24 hrs duration; ALS induced a selective lymphopenia. 3 hrs after i.v. injection of antiserum phagocytosing liver cells showed the following alterations: AMS reduced the number of intact Kupffer cells, but increased the activity of cells still present which phagocytosed monocytes and granulocytes. ALS, on the other hand, did not reduce the number of Kupffer cells but induced phagocytosis of lymphocytes. These results were discussed within the framework of our studies on specificity of reactions of heterologous antisera after their exhaustive absorption with different, cross-reacting cells.
