Abstract
Involvement of hypothalamic-pituitary-adrenocortical axis into the analgesic effect of corticotropin-releasing hormone after its systemic administration was studied in experiments on rats. Pharmacological blockade of the hypothalamic-pituitary-adrenocortical axis decreased the duration and degree of the analgesic effect of corticotropin-releasing hormone. This analgesic effect can be mediated via two pathways: related to hormones of the hypothalamic-pituitary-adrenocortical axis and independent of these hormones.
