It was determined that tumor necrosis factor (TNF) is capable of decreasing the local brain's blood flow on 45.6% (in the concentration of 6 micrograms/kg); to make a spasm of the pial arteries on 39.6%. In vitro experiments TNF increased the amplitude of the rhythmical and the tonic contractions of the brain's arteries smooth muscles (3.6 X 10(-8) M). The direct action of the TNF in the vascular wall is endothelium-dependent.
