The effect of exposure to ether on prolactin secretion and the half-life of endogenous prolactin in normal and castrated male rats.

abstract：:Structural and functional impairment of the skeletal system remains an important cause of morbidity and disability in patients with Cushing's syndrome (CS). Glucocorticoid (GC) excess inhibits bone formation and calcium absorption from the gut, increases bone resorption, and alters the secretion of gonadotropin and gr...
