    Description / Table of Contents: Zusammenfassung Trotz vorheriger Gabe von Propranolol bewirkt Oxyfedrin beim Hund einen signifikanten Anstieg der Frequenz, des arteriellen Spiegels der freien Fettsäuren, der arteriellen 3-Hydroxybutyrat-Konzentration und der Aufnahme von freien Fettsäuren in die Leber sowie eine ebenfalls statistisch gesicherte Verminderung des coronaren Widerstandes. Ein Vergleich der gefundenen Wirkungen mit bereits publizierten Ergebnissen zeigt dennoch eine, wenn auch nur partielle Blockierbarkeit der Oxyfedrineffekte durch Propranolol. Die anderen, z. T. gegenüber der alleinigen Gabe von Oxyfedrin sogar verstärkten Wirkungen wie die signifikante Abnahme des arteriellen Spiegels und der myokardialen Bilanz von Pyruvat werden durch gleichsinnige, additive Wirkungen von Propranolol und Oxyfedrin erklärt.
    Notes: Summary Following beta-adrenergic blockade with propranolol, infusions with oxyfedrin caused significant increases in heart rate, arterial free fatty acids and 3-hydroxy-butyrate levels, uptake of free fatty acids into the heart and liver, and a significant decrease in coronary vascular resistance. A comparison with data from previous experiments without beta-adrenergic blockade shows at least a partial blockade of the hemodynamic and metabolic effects caused by oxyfedrin. The other metabolic parameters, showing identical changes with oxyfedrin and propranolol, could not be taken for a comparison of the action of oxyfedrin before and after betaadrenergic blockade.

    Notes: Summary The intravenous infusion of fructose (0.7 and 2.4 g/kg/30 min) increases the incorporation of14C-glycine into rat liver adenine nucleotides significantly as compared to controls treated with 0.9% NaCl. A decrease of the total adenine nucleotide content of the livers occurs concomitantly. In contrast to its effect upon liver tissue fructose neither effects the content of adenine nucleotides nor the incorporation of glycine into these nucleotides in skeletal muscle of rats. — The results support the hypothesis that large quantities of fructose cause an increasedde novo synthesis of purine nucleotides in the liver. However, they do not as yet present clear cut evidence as to whether this is a direct effect of fructose or is secondary to the depletion of adenine nucleotides.

    Description / Table of Contents: Summary Erythrocyte metabolism studies in a case with hereditary spherocytosis only showed minimal deviations of the activity of the enzymes of glycolysis from the normal values. The formation of lactate was increased, the intracellular sodium concentration was increased and the intracellular potassium concentration was decreased. The methemoglobin level of the erythrocytes was increased. After splenectomy, which resulted in a good clinical and hematological remission, lactate formation and the abnormal electrolyte and methemoglobin level of the erythrocytes returned to normal.
    Notes: Zusammenfassung Untersuchungen des Stoffwechsels der Erythrozyten bei einem Fall von hereditärer Sphärozytose ergaben nur geringe Abweichungen der Aktivität der Fermente der Glykolyse von der Norm. Die Bildung von Laktat war gesteigert, der Gehalt an intrazellulärem Natrium vermehrt und an Kalium vermindert; der Methämoglobingehalt der Erythrozyten war vermehrt. Nach der Splenektomie, die zu einer guten klinischen und hämatologischen Remission führte, normalisierte sich die Laktatbildung und der abnorme Elektrolytund Methämoglobingehalt der Erythrozyten.

    Description / Table of Contents: Zusammenfassung In den Erythrocyten eines Falles von Trisomie G-21 konnte im Gegensatz zu bisher vorliegenden Berichten eine Verminderung der Aktivität von Phosphofructokinase (PFK) gefunden werden. Daneben wurde eine hohe Aktivität der Glycerophosphatdehydrogenase und in geringerem Ausmaß auch anderer Enzyme nachgewiesen. Die mit dem PFK-Mangel in Zusammenhang stehenden Stoffwechselstörungen sowie die Frage der genetischen Lokalisation dieses Enzyms werden diskutiert.
    Notes: Abstract A deficiency of erythrocyte-phosphofructokinase has been demonstrated in a case of Trisomy-G-21. This is in contrast to findings of other authors who reported an increase of erythrocyte-PFK in cases of Down's syndrome. The metabolic changes caused by PFK deficiency and the problem of genetic localization of this enzyme are discussed. In addition an increased activity of glycerophosphate-dehydrogenase and, to a lesser degree, some other enzyme was found in the patients red blood cells.
