BIOPHYSICAL AND CHEMICAL INVESTIGATION ON BONE TISSUE IN EXPERIMENTAL HYPERPARATHYROIDISM1

Abstract
Effects of parathyroid hormone on bone tissue were investigated by studying rate of renewal of bone phosphate using chemical and autoradiographic techniques, and general distribution of mineral salts using microradiography. In young animals rate of renewal of bone phosphate is decreased but is increased in the case of old animals. Destruction of bone tissue is accelerated by parathyroid hormone, but characteristics of the process are unchanged.
