直接凝血酶抑制物的测定及其临床意义 |
|
【摘要】 目的 采用稀释血浆凝血酶时间法(稀释纠正法)检测血浆中特异性凝血酶抑制物,为抗血栓形成治疗提供有效的实验室监测试验。方法 延长的凝血酶时间(TT)用正常人混合血浆作1∶4稀释后作TT测定。结果 稀释纠正法测的直接凝血酶抑制物(direct thrombin inhibitors,DTIs)浓度与TT有良好的相关性(r=0.9569),可测最低DTIs浓度为8.0×10-3 μg/ml,测得凝血酶抑制药物阿加曲班治疗患者DTIs血浆浓度为118.2±20.78×10-3 μg/ml,不明原因轻度出血异常、急性白血病患者也存在不同程度的DTIs。结论 稀释纠正法TT测定对DTIs有较高的特异性和敏感性,是凝血酶抑制物类药物治疗血栓性疾病有价值的实验室监测指标。

Abstract: Objective To detect specific thrombin inhibitors with a plasma diluted thrombin time and find an effective method for laboratory monitor of anticoagulant and thrombolytic therapy.Methods Patient samples were 1∶4 dilutions with normal plasma and the diluted thrombin time was examined by ACL9000.Results The direct thrombin inhibitors (DTIs)detected by diluted thrombin time were associate with the thrombin time(r=0.9569),the lowest density of DTIs was 8.0×10-3μg/ml,the DTIs density of patients spiked with argatroban was (118.2±20.78)10-3μg/ml,the DTIs were also detected in patients with unknown bleeding and acute leukemia.Conclusion Detectin[1] [2] [3] [4] 下一页 上一个医学论文: 习惯性流产的抗凝血酶原抗体IgG IgM检测的初步应用 下一个医学论文: 血小板膜GP b 基因多态性与血栓性疾病相关性的研究进展
