Insulin sensitivity and lipid profile in prolactinoma patients before and after normalization of prolactin by dopamine agonist therapy.

abstract：:Glucocorticoids are important immunosuppressive hormones; these steroids also inhibit somatic growth by decreased growth hormone (GH) secretion and induced protein catabolism. The ability of ghrelin, the endogenous ligand for the GHS-1a receptor, to increase body weight is attributed to a combination of enhanced food ...
