Action of Parathyroid Hormone in Normal and Hypophysectomized Pigeons. ∗

Abstract

Summary

The parathyroid hormone (parathormone) effectively increases the serum calcium level in normal, hypophysectomized and in thyroidectomized pigeons. Pigeons are therefore to be added to the few species now known to be suitable for use in studies which seek to identify the particular anterior pituitary hormone which stimulates the parathyroids. The parathormone preparation used contained something which led to increased blood sugar values in 5 of 6 tests made on normal pigeons.
