Abstract
Many methods have already been used for modeling calcium metabolism (MILHAUD et al., 1957, MARSHALL, 1969). If their characteristics were widely differing, they were in common based on both mathematical procedures and physiological data which require to be reconsidered to-day. Recently, three of the authors reported that, in the rat, plasma calcium fluctuates following a clear circadian rhythm (PERAULT-STAUB et al., 1973). Our present study includes detailed knowledge of plasma 45Ca decay and shows that rhythmicity may be considered as an essential property of the processes involved in calcium metabolism. Moreover, during the modeling, we have attempted to include the new concepts of calcium homeostasis (TALMAGE, 1970; MATTHEWS et al., 1971).
The authors are grateful to Dr. G. COUTRIS for his valuable suggestions during the preparation of this manuscript.
