Effects of total flavone of Abelmoschl Manihot L. Medic on the function of platelets and its mechanism
摘要
Objective: To study the effects of total flavone of Abelmoschl Manihot L. Medic (TFA) on the function of platelets and to explore its mechanism.Methods: Rat models of artery-veins bypassing thrombus formation were used. The platelets of rabbits were collected. Platelet aggregation was induced by collagen and intracellular calcium ion concentration ([Ca2+]i) was assayed by Fura-2 method.Results: TFA (25
50
100 mg/kg) significantly and dose-dependently reduced the weight of thrombus. TFA (0.025
0.05
0.1 mg/ ml) possessed dose-dependant inhibitory effects on rabbits’ platelet aggregation induced by collagen. TFA significantly reduced the resting and CaCl2-induced increase of free intracellular calcium concentration ([Ca2+]i) in rabbit plateletin vitro.Conclusion: TFA has an antiplatelet effect via the inhibition on the influx of Ca2+.
