title: Decrease of plasma somatotropin levels following thyroliberin (TRH) administration in patients with hyperthyroidism.
abstract: Thyroliberin was observed to induce a significant decrease of plasma somatotropin levels in patients with untreated hyperthyroidism, except those with very low initial somatotropin levels. These data have confirmed our previous finding where we noted that under the conditions of thyroid hormone excess thyroliberin was able to exert an inhibitory effect on somatotropin release.
