The Relative Influence of Calcium, Strontium and Magnesium on Calcitonin Secretion in the Pig

Abstract
Young pigs were infused in vivo with solutions of calcium, magnesium and strontium. Calcitonin was measured by radioimmunoassay in blood samples taken from an indwelling jugular catheter placed in the vicinity of the thyroid venous drainage. A several-fold rise in plasma concentration of magnesium or strontium was followed by a rise in plasma CT. A comparison of equimolar infusions of calcium, magnesium, and strontium suggests that the relative sensitivity of the CT secretory mechanism to these cations is calcium > strontium >magnesium.(Endocrinology94: 1176, 1974)
