|Title: ||CIRCANNUAL RHYTHMS IN THE ACTIVITY OF THE PARATHYROID-GLAND AND ULTIMOBRANCHIAL BODY CELLS OF THE FROG RANA-TEMPORARIA (ANURA, AMPHIBIA)|

|Abstract: ||The annual activity of the parathyroid gland cells and those of the ultimobranchial body cells of the frog Rana temporaria is quantitatively investigated by a morphometric study. A cosinor analysis shows a periodic succession of different parameters. The secretory activity of the parathyroid cells starts after a maximal value of external temperature in July. This activity is followed by an increase of plasma calcium which seems to induce the activity of the ultimobranchial cells.|
