Abstract:
Objective To observe the effect of grape seed Procyanidins on platelet aggregation and experimental thrombosis in rats.Methods 50 Experimental thrombosis male SD rats of clean grade,weighing 250～300 g,were randomly divided into five groups,normal saline(control)group,aspirin(ASP)group(60 mg/kg),and procyanidins 1 00 mg/kg,200 mg/kg,400 mg/kg group,10 in each.50 experimental thrombosis male Kunming mice of clean grade,weighing 18～20 g,were also randomly divided into five groups,normal saline(control)group,aspirin group(84 mg/kg)and Procyanidins 140 mg/kg,280 mg/kg,560 mg/kg group,10 in each.Intragastric administration was performed in these experimental animals.The effects of Procyanidins were observed on rat platelet aggregation induced by ADP,COL and AA.Experimental rat's thrombosis was induced by method of"arterio-venous"shunt and the death rate within 15 min was determined with collagen plus adrenaline induced thrombus model in mice,aspirin as a positive control.Results Procyanidins in the middle and high-dose group can inhibit ADP,COL,AA-induced platelet aggregation and experimental thrombosis obviously.Conclusion Procyanidins can inhibit experimental thrombosis and have anti-platelet aggregation effect.
