With stock diets (Ca: P = 1.1: 1) parathormone produced hyperostosis, and with higher doses, osteitis fibrosa. With diets containing optimal Ca and high P (Ca: P = 1: 2.3) relatively lower doses of parathormone produced fibrosis. The hormone failed to prevent rickets. Moderate hypercalcaemia and hyperphosphataemia resulted from parathormone administration; the hyperphosphataemia depended on the dose of hormone and on the P intake.
