Effects of Methyl Protodioscin on In-Vivo and In-Vitro Thrombosis and Blood Viscosity in Rats

Objective To investigate the effects of methyl protodioscin (MPD ) on in-vitro and in-vivo thrombosis and blood viscosity in rats. Methods The vitro thrombus was induced by Chandler method,and the length,wet and dry weight of the thrombus were measured. Thrombosis instrument was to observe the in-vivo occlusion time (OT). At the same time,determined the high-,middle-,low-shear blood viscosity as well as the plasma viscosity in rats was determined .Results Compared to normal group,middle-dose MPD group can delay the OT,and the high-dose group can decrease the length,wet and dry weight of in-vitro thrombus. The blood viscosity is reduced in all groups. Conclusion MPD can inhibit the in-vitro thrombosis,decrease the dry and wet weight of thrombus and delay the OT. Moreover,MPD has the effects of lowering the whole blood viscosity and plasma viscosity.
