Effect of fibrinogen degradation products on the rat blood vessels.

Effect of fibrinogen degradation products on the rat blood vessels. Acta Physiol. Pol. 1977, 28 (2): 153--159. It was found that fibrinogen degradation products (FDP) exert a slight hypotensive effect and increase the flow of Tyrode's solution through isolated hindpaw of rat. The investigated peptides failed to change significantly the action of noradrenaline and had an additive effect with isoprenaline. Propranolol reduced the effects of FDP and isoprenaline. It is suggested that the described effects may be due to stimulation of the vascular beta-adrenergic receptors by FDP.
