title: Development of tolerance to the ACTH-releasing effects of beta-endorphin.
abstract: Acute intracisternal injection of human beta-endorphin results in increased plasma concentration of adrenocorticotropic hormone (ACTH). Repeated injections of beta-endorphin are associated with the development of tolerance with regard to this ACTH-stimulating effect.
