Stress-induced dependence on endogenous opioid peptides--a fundamental process in the pathophysiology of a disturbed...

Using previous findings of stress-induced disturbances in regulation of peripheral and central function within the general adaptation process and hints from the literature to a multiple participation of opioid peptides in adaptive processes, this paper represents experimental data which gives hints to a functional relation in the etiopathophysiology between the development of stress-induced dependence on endogenous opioid peptides and stress-induced disturbances in blood pressure regulation and to the adaptive effect of substance P within the peptidergic interaction with endogenous opioid peptides and its importance for the physiology or pathophysiology of adaptive processes.
