Influence of Dietary Stable Strontium and Calcium on the Turnover of Bone-Fixed Sr 85 in Man. ∗

Summary

The turnover of Sr⁸⁵ was determined for four patients by wholebody counting for a period of 130 days following administration of the isotope. The data obtained were expressed as power functions. Two patients then received Sr lactate, and the other two Ca gluconate as dietary supplements for a period of 110 days. Sr⁸⁵ turnover was determined for this period and again expressed as a power function for each patient. While the data suggested that the addition of Ca gluconate to the diet somewhat decreased Sr⁸⁵ excretion and the addition of Sr lactate slightly enhanced excretion, no statistically significant changes in the long-term turnover rate of Sr⁸⁵ were observed.
