Abstract
To study the effect of 3,4',5-trihydroxystibene-3-beta-mono-D-glucoside (Polydatin, Pol) on rabbit arterial thrombosis. Rabbit arterial thrombosis was induced by vascular endothelial damage with trypsin. It was showed that the moist weights of the thrombus were 6.6 +/- 1.8 and 4.8 +/- 1.6 mg in Pol 5 and 10 mg.kg-1 groups, respectively, which was lighter than that in control (10.9 +/- 1.9 mg, P < 0.05, P < 0.01); the platelet aggregation was inhibited simultaneously. In vitro, Pol 0.30-1.15 mmol.L-1 reduced TXA2 produced in platelets. It did not affect the production of PGI2 in cultured human umbilical vein endothelial cells. Thrombosis was abated by Pol. The selective inhibition of production of TXA2 rather than PGI2, is one of the mechanisms involved.
