摘要

5,6-反式前列腺素E2 (trans- pge2)被发现在无细胞系统中加速纤维蛋白溶解。反式pg E2在纤维蛋白凝块裂解时间法中使裂解时间缩短15%,在纤维蛋白平板法中使裂解面积增加22%。相反,5,6-顺式前列腺素E2则没有这种作用。在缺乏组织型纤溶酶原激活剂或纤溶酶原的情况下,反式pge2均不发挥作用。这些结果表明,反式pg E2通过组织-纤溶酶原激活剂促进纤溶酶原产生纤溶酶。

Trans-prostaglandin E2 enhances fibrinolysis.

5,6-trans-Prostaglandin E2 (trans-PG E2) was found to accelerate the fibrinolysis in a cell-free system. trans-PG E2 decreased the lysis time by 15% in the fibrin clot lysis time method and increased the lysis area by 22% in the fibrin plate method. On the contrary, 5,6-cis-prostaglandin E2 did not have such effects. trans-PG E2 did not exert the effect in the absence of either tissue-plasminogen activator or plasminogen. These results suggest that trans-PG E2 enhances the generation of plasmin from plasminogen by tissue-plasminogen activator.
