摘要
对二十碳五烯酸(EPA)的抗栓作用及其机制进行了研究。结果表明,EPA在体内、体外均有明显抗栓作用,并能增强纤溶活力,缩短优球蛋白溶解时间,抑制花生四烯酸和胶原诱导的大鼠血小板聚集。放射免疫测定证明,EPA能降低小鼠血浆血拴素B_2(TXB_2)含量,提高6-酮前列腺素F_(1α)与TXB_2的比值。
The effects of eicosapentaenoic acid (EPA) on experimental thrombosis and its mechanism were studied. The results showed that eicosapentaenoic acid had a significant antithrombolic effect both in vivo and in vitro . EPA also had a fibrinolytic activity and can shorten euglobulin lysis time. Our studies also showed that EPA can inhibit platelet aggregation in rats. The plasma concentration of 6-keto-PGF1a and TXB2 was measured by radioimmunoassay. The results showed that EPA can reduce the contents of TXB2 and raise 6-keto-PGF1a/TXB2 ratio.
