    Notes: Summary A 20-month-old girl with massive digitoxin intoxication (initial digitoxin serum level: 629 ng/ml) was successfully treated with digoxin-specific antibody fragments (Fab). She presented with moderate signs of digitalis toxicity (somnolence, bradycardia, first-degree AV block) and improved rapidly during fractional Fab administration. Free serum-digitoxin disappeared after 6 vials of Fab (480 mg), but was measurable again on days 6 and 7. This case demonstrated that digoxin-specific antibodies, despite a 30–100 times lesser affinity for digitoxin, are effective in massive digitoxin intoxications. A rebound phenomenon may occur several days later and should be taken into consideration.

    Description / Table of Contents: Summary If the concentration of elements with Z〉22 (Ti) is to be determined in mineral samples and if the concentration of any of these elements is greater than ≈ 1%, the sample is diluted by grinding it together with an appropriate amount of quartz powder in an agate mortar mill. The diluted sample is measured in powdered form in a spectro-cup at practically infinite thickness by energy-dispersive X-ray fluorescence; the counting rates are corrected by means of the Compton scattering peak and evaluated by use of calibration curves obtained by measuring standards on the basis of silica gel. The applicability of this method is established by measuring the concentrations of 12 elements with Z〉22 in 14 mineral samples of varying composition.
    Notes: Zusammenfassung Wenn die Konzentration von Elementen mit Ordnungszahlen Z〉22 (Ti) in mineralischen Proben bestimmt werden soll, und wenn die Konzentration eines dieser Elemente größer als ≈ 1% ist, wird die Probe durch Mahlen mit einer geeigneten Menge Quarz-Pulver in einer Achatmörsermühle verdünnt. Die verdünnte Probe wird in Pulverform in einem „spectro-cup“ bei praktisch unendlicher Schichtdicke durch energiedispersive Röntgenfluorescenz gemessen, die Zählraten werden mit Hilfe des Compton-Streupeaks korrigiert und unter Verwendung von Eichkurven ausgewertet, die durch Messung von Standards auf der Basis von Silicagel erhalten werden. Die Anwendbarkeit dieser Methode wird überprüft durch Bestimmung der Konzentration von 12 Elementen mit Ordnungszahlen Z〉22 in 14 mineralischen Proben verschiedener Zusammensetzung.
