[The content of some prostanoids and status of the functional activity in the brain stem of adolescents with vegetovascular dysfunction of the hypotensive type].
A correlation analysis was performed between parameters associated with the bioelectrical activity of truncus cerebri and indices for blood level of prostanoids. Our assumption is that in adolescents suffering from hypotensive type vegetovascular dysfunction, brain truncal structures participate in regulation of hemodynamics in a relatively autonomous fashion. Regulation of vascular tone in essentially healthy juveniles and in those presenting with hypotensive type vegetovascular dysfunction has different mechanisms related to redistribution of priorities of effects of those groups of prostanoids having been studied. Autonomic regulation of hemodynamics through prostaglandins does not prevent them from exerting their influence on blood supply of the truncal structures, which fact might be a manifestation of the mechanism of closure of the feedback in the chain of regulation of arterial pressure in both healthy and sick juveniles.
