[Effect of adrenaline and noradrenaline on the vascular antiaggregation activity in cats].

The anti-aggregation ability of vessels from different circulatory zones was studied under the influence of adrenaline and noradrenaline. Dissimilarity of the basal antiaggregation activity of the vessel wall of various circulatory zones was revealed. The complex character of influence of catecholamines on the anti-aggregation ability of the vessel wall was revealed, the final result of which depends greatly on the initial anti-aggregation activity of the vessel wall.
