Abstract
Twelve normal subjects have been studied using calcium balance techniques and47Ca to provide normal reference values for metabolic calcium studies in adult humans. A composite graph of plasma and urinary calcium specific activities is presented at intervals from 0.1 to 300 hours after isotope injection. It is suggested that an adequate representation of this data may be made by means of two power functions, and the practicality of this interpretation is discussed.
Résumé
Des techniques permettan l'étude de l'équilibre calcique et du47calcium ont été utilisées chez douze sujets normaux pour apprécier le métabolisme calcique chez l'homme adulte. Un graphique des activités spécifiques du calcium plasmatique et urinaire est dressé de 0.1 à 300 heures après l'injection isotopique. Il semble qu'une interprétation satisfaisante de ces résultats puisse étre réalisée à l'aide de deux fonctions de puissance et l'intérêt de cette interprétation est analysé.
Zusammenfassung
12 Gesunde wurden mit der Ca-Bilanztechnik unter Verwendung von Ca47 untersucht, um Bezugsgrößen für Ca-Stoffwechseluntersuchungen bei Erwachsenen zu erhalten. Ein Diagramm der spezifischen Aktivitäten im Plasma und Harn 0,1–300 Std nach einer Isotopeninjektion wird dargestellt. Man folgert, daß eine gleichmäßige Wicdergabe dieser Werte durch eine zweigliedrige Funktion möglich ist; die praktische Bedeutung dieser Interpretation wird diskutiert.
