采用火箭电泳法、单向琼脂扩散法和放射免疫法，分别检测４３例再障患者血液中ＡＴ－Ⅲ、α２－Ｍ、α１－ＡＴ及ＰＣ含量。结果表明，ＡＴ－Ⅲ、α２－Ｍ，ＰＣ抗原含量明显高于３９例正常对照（Ｐ均＜０．１），２９例口服康力龙者ＡＴ－Ⅲ、α２－Ｍ，ＰＣ含量较１４例未服康力龙者显著增高（Ｐ＜０．０１）。提示ＡＴ－Ⅲ、α２－Ｍ、ＰＣ含量增高可能是引起再障出血的原因之一。推测抗凝血蛋白增高与再障病人单核－巨噬细胞清除能力下降和应用蛋白同化类固醇激素有关。结果还显示，α１－ＡＴ含量随着出血程度加重而减低，故可作为再障出血的监视指标，并有利于动态观察病情。
The concentrations of AT-Ⅲ, α2-M, α1-AT and PC in blood of 43 patients with aplastic anemia were detected by rocket electrophoresis, one-way agar diffusion and radioimmunoassay respectively. The results showed that the content of AT-Ⅲ, α2-M and PC antigen was significantly higher than that of 39 normal controls (all P <0.1). The AT-Ⅲ, α2- Conor Long were significantly higher (P <0.01). Tip AT-Ⅲ, α2-M, PC content may be one of the causes of aplastic anemia. It is speculated that elevated anticoagulant protein and aplastic anemia in patients with monocyte - macrophage clearance decreased and the application of protein assimilation steroids. The results also showed that α1-AT content with the degree of bleeding aggravated and decreased, it can be used as a marker of aplastic anemia, and is conducive to dynamic observation of the disease.
