已知苯具有血液毒性近一个世纪了。苯引起白细胞减少、血小板减少和全血减少。苯引起再生障碍性贫血的临床表现和血象与一般的再生障碍性贫血相同。有时有轻微的胆红素血症,渗透脆性改变,乳酸脱氢酶和粪胆素原升高,偶尔发现神经异常。电子显微镜在一些再生障碍性贫血病例中的发现与光学显微镜的观察所得相似。在接触苯的1名技术人员中见到 It has been known that benzene has hematotoxicity for nearly a century. Benzene causes leukopenia, thrombocytopenia and decreased whole blood. Benzene aplastic anemia caused by clinical manifestations and blood and the same as the general aplastic anemia. Sometimes there is a slight bilirubin, osmotic fragility changes, lactate dehydrogenase and proanthogenin increased, and occasionally found neurological abnormalities. The findings of electron microscopy in some cases of aplastic anemia are similar to those obtained with light microscopy. See a technician in contact with benzene
