0-/-B-hydroxyethyl/rutoside has been investigated for its effect on laser-induced thrombus formation in rat mesenteric venules and arterioles. The in vitro effect of this agent on platelet adhesion to bovine subendothelial extracellular matrix (ECM) and glass, on spreading and on platelet aggregation induced by ADP, collagen and epinephrine have also been studied. The animal investigations of 0-/-B-hydroxyethyl/rutoside showed an antithrombotic effect in doses between 5 and 50 mg/kg after i.v. injection. This effect was similar for both arterioles and venules damaged. After i.v. injection of minimum effective doses of 0-/-B-hydroxyethyl/rutoside, the antithrombotic effect lasted longer than 6 hrs but less than 12 hrs. In vitro, 0-/-B-hydroxyethyl/rutoside significantly inhibited platelet adhesion to bovine ECM in concentrations of 20 micrograms/ml PRP, and with 30 micrograms/ml the PRP adhesion to glass and spreading were inhibited. Epinephrine and ADP induced aggregation was inhibited in concentrations higher than 30 micrograms/ml PRP.
