[Interrelation of the epiphysis and parathyroid glands]

Synergism between parathyroidin and epithalamin (an extract from the cattle epiphyses) with relation to phosphorus metabolism was revealed in experiments on guinea-pigs. Both drugs possessed a hypophosphatemic effect. The influence of epithalamin on calcium metabolism was mediated by changes in parathyroid function. An elevation of the parathyroid hormone in the blood was noted after the administration of epithalamin.
