摘要
凝血酶可诱导单个核细胞与血小板之间发生聚集,此聚集为一Ca^(2+)依赖过程。川芎嗪对此有明显的抑制作用,呈剂量—效应关系。川芎嗪也可预防静注凝血酶引起的小鼠周围血白细胞计数下降,提示在体内也可能抑制白细胞聚集。当归、丹参酮Ⅱ_A等血小板抑制剂对凝血酶诱导的单个核细胞—血小板聚集无明显影响。
Thrombin-induced aggregation between mononuclearcytes and platelets was investigated and shown to be calcium dependent. Tetrame-thylpyrazine inhibited the aggregation and a dose-effect relationship was demonstrated. Tetramethylpyrazine also prevented the decrease of blood leukocyte count induced with thrombin venous injection in mice. Angelica sinensis Diels and tanshinone did not show any obvious effects on thrombin-induced aggregation between mononuclearcytes and platelets.
