PERMEABILITY OF BLOOD BRAIN BARRIER FOR CARDIOTROPIC SUBSTANCES UNDER HYPOTHERMIA AND HYPERTENSION

It has been shown that under hypothermia conditions the interactions between central and autonomous contours of cardiac activity regulation can be significantly changed, therefore the probability of paradoxical reactions of an organism to application of cardiotropic preparations increases. The change of a sign of chronotropic effect of cathecholamines (CA) and acethylcholine (AC) under hypothermia in a great extent is substantiated by an increase of blood brain barrier (BBB) permeability, that should be taken for consideration in practical medicine. Besides therapeutic cooling regimens contribute to a recovery of impaired rhythmicity of functioning of nerve and cardiovascular systems, in particular under conditions of emotional stress, that is one main causes of human disease appearing.
