导言医疗专业人员在对与疾病检测、处理或预防中使用的药物、装置和操作相关的证据的严格评价中扮演的核心角色是十分必要的。对涉及这些疗法和操作的绝对和相对益处和风险的现有资料进行适当和严格的专业分析,可通过将资源集中于最有效的治疗策略,从而改善治疗效果、优化患者转归和合理控制成本。这些资料的一种重要应用是制定临床实践指南,后者进而能为其他各种应用,如绩效评价、合理应用标准、临床决策支持工具和质量改进工具提供依据。  相似文献

A monoclonal antibody, LK-4, has been developed which distinguishes platelet PLA1/PLA1, PLA1/PLA2 and PLA2/PLA2 genotypes on platelet glycoprotein GPIIIa of Triton-solubilized platelet extracts. An ELISA assay has been developed which traps GPIIIa with Concanavalin A, enriching the platelet extract for the PLA antigens. A second monoclonal antibody, DEK-10, which reacts equally with GPIIIa of PLA1/PLA1 and PLA2/PLA2 platelet extracts is employed as an internal standard to correct for individual differences in GPIIIa content, GPIIIa extracted by Triton X-100 and GPIIIa trapped with Concanavalin A. This ELISA assay clearly differentiated 11 different PLA1/PLA1 subjects from eight PLA2/PLA2 women with a history of neonatal alloimmune thrombocytopenia as well as six unrelated obligate heterozygotes and should be useful in evaluating the PLA genotype of pregnant women and their families.  相似文献

A New Platelet Antigen System, Yuka/Yukb   总被引:3,自引:0,他引:3  
We report a new platelet antigen (Yukb) involved in a case of neonatal alloimmune thrombocytopenia (NAITP). This antigen is considered to be a product of an allele of the Yuk gene, another allele of which codes for Yuka which was involved in 2 cases of NAITP. The Yuka and Yukb antigens are not expressed on thrombasthenic platelets which suggests that these antigens are present on platelet glycoprotein IIb and/or IIIa. The gene frequencies for Yuka and Yukb in the Japanese population were estimated to be 0.0083 and 0.9917, respectively.  相似文献
