The arterial antithrombotic activity of thioxylosides in a rat model of laser-induced thrombosis.

beta-D xylosides have been shown to have venous antithrombotic properties after simple oral administration. Therefore, the arterial antithrombotic effect of these compounds was investigated in vivo, using the experimental thrombosis model induced by laser injury. The products tested were administered orally, 4 h before the thrombosis induction.

Effect of the low molecular weight heparin/non steroidal anti-inflammatory drugs association on an experimental thrombosis induced by laser.

LMWH (Fraxiparine), and NSAIDs (Aspirin, Feldene, Indocid and Profenid) injected together in doses, 1 mg/kg (Aspirin was used at 100 mg/kg), subcutaneously into rats 30 minutes before the thrombosis induction by LASER beams, increased the number of LASER beams required to induce platelet thrombus formation, decreased the number of emboli and reduced the duration of embolization, compared with control (p < or = 0.05). Of all the studied NSAIDs being injected either with LMWH or separately 30 minutes before the thrombosis stimulation by LASER only Aspirin appeared to potentiate the antithrombotic effect of Fraxiparine.
