摘要
以新鲜全血制备白细胞冻溶上清液，进行其促血小板聚集和促凝血时间的对照研究，结果发现，临床甲襞微循环检查肯有白色微小务珠患者血小板聚集率明显增高及凝血时间缩短明显（Ｐ〈０．００１），证实白细胞确有促凝物质的存在并参予了白色微小血栓的形成。
Supernatance of frozed-melted leukocyte coming from fresh whole blood was researched into platelet proaggregation and procoagulation time using double-blind control methods. Result indicated that rate of platelet aggregation of patients with white microthrombi by detecting microcirculation of hand nailfold was significantly higher compared with control group(P＜0.001),but coagulation time of patients was significantly shortened (P＜0. 001). These findings suggested that leukocyte did include with procoagulant and participated in white microthrombosis.
