Abstract
Summary
The effect of salmon calcitonin on the rate of disappearance of simultaneously administered 32P was studied further in rats. It was demonstrated that at 1 hr postin-jection the 32P plasma values were significantly lower in calcitonin-injected rats than in their controls. This difference was seen in normal, thyroidectomized, nephrectomized and parathyroidectomized rats indicating that this was a direct effect of calcitonin independent of renal or parathyroid function. The data in this study confirm the earlier report that calcitonin causes a rapid movement of phosphate out of plasma.
