    Description / Table of Contents: Zusammenfassung Durch drei chemische Carcinogene wurden Darmtumoren bei Ratten induziert. Nur bei durch 1,2-Dimethylhydrazin induzierten Tumoren konnte eine schwache Reaktion auf eine Kombinationschemotherapie mit Adriamycin, Methotrexat, 5-Fluorouracil und Cyclophosphamid beobachtet werden. Das gleiche Therapieschema versagte bei durch N-Methyl-N′-Nitro-N-Nitroso-Guanidin und durch Acetoxymethyl-Methyl-Nitrosamin induzierten Tumoren. Diese Ergebnisse und die Vergleichbarkeit der Chemotherapie autochthoner Tumoren mit experimentellen und klinischen Beobachtungen werden diskutiert.
    Notes: Summary Intestinal tumors in rats were induced by three different chemical carcinogens. Only tumors induced by 1,2-dimethylhydrazine responded slightly to combination chemotherapy of Adriamycin, Methotrexate, 5-Fluorouracil, and Cyclophosphamide. The same therapy failed in tumors induced by N-methyl-N′-nitro-N-nitroso-guanidine or acetoxymethyl-methyl-nitrosamine. These results and the comparability of chemotherapy in autochthonous tumors to experimental and clinical observations are discussed.

    Description / Table of Contents: Gibberellins. XXXV. Synthesis of Neutral and Amino-substituted Amides of the Gibberellin A3 and A1 SeriesThe synthesis of neutral and amino-substituted amides of the gibberellin A3 and A1 series via aminolysis of the corresponding gibberellin carboxylic acid anhydrides is described. The mass spectra and 1H-NMR data of these compounds are discussed.
    Notes: Es wird die Synthese einer Anzahl neutraler und basischer Amide der Gibberellin-A3- und -A1-Reihe durch Aminolyse entsprechender Gibberellinanhydride beschrieben. Massen- und 1H-NMR-spektroskopische Befunde an dieser Verbindungsklasse werden mitgeteilt.
