The effect of chicken and hog calcitonin on some parameters of Ca, P, and Mg metabolism in dogs

Abstract

Partially purified calcitonin extracted from both chickens and hogs was injected intravenously into young dogs. The effects of each extract were essentially similar in causing immediate depression of both plasma Ca and P but not Mg. The preparations caused hyperphosphaturia and decreased urinary excretion of magnesium. Gut transport of Ca, P, or Mg in either direction was unaffected by the extracts.
