in studying the additive and potentiating effect on acth release of crf in combination with vasopressin , vip and the catecholamines it became evident that only the combination of micromolar concentrations of epinephrine or norepinephrine together with nanomolar concentrations of crf will make acth release significantly less sensitive to the suppressive effect of dexamethasone .
