Abstract: | The review focuses on the concept of biological stress pioneered by Hans Selye, who demonstrated a key involvement of the pituitary-adrenocortical axis in the response to stress. It discusses the historic background of development of the stress concept and some aspects of modern physiological researches related to stress-induced activation of the hypothalamic-pituitary-adrenocortical axis. We focus mainly on the results demonstrating that stress-induced activation of the hypothalamic-pituitary-adrenocortical axis is a gastroprotective component of stress response. |
