Prolactin and TSH response to TRH and metoclopramide before and after l-thyroxine therapy in subclinical hypothyroidism.

abstract：:We have previously shown that the diterpene forskolin, a compound which increases intracellular cyclic AMP (cAMP), causes a concentration-dependent release of luteinizing hormone (LH) by continuously perifused anterior pituitary cells from female rats. To test the hypothesis that cAMP-associated LH release is an estro...

Angiotensin acts on and through the amygdala to stimulate thirst and sodium appetite. In addition, different angiotensins seem to play a role in cognition and learning mechanisms by acting on and through t...
