流行性出血热(简称出血热),是一种发病急、病情重、病死率高的自然疫源性疾病。至今尚无特异性实验诊断方法,其血象中出现类似“传染性单核细胞增多症”的异常淋巴细胞(简称异淋),对早期诊断有重要的参考意义。现将我院1980～1981年确诊的118例出血热住院患者血象中异淋的观察结果报告如下。材料与方法从病人入院开始,隔日一次,在手指采血涂片、瑞氏染色后油镜下计数100或200个白细胞,分 Epidemic hemorrhagic fever (referred to as hemorrhagic fever), is a natural disease of acute onset, severe illness and high mortality. There is no specific method of experimental diagnosis, the blood appears similar to “infectious mononucleosis syndrome” abnormal lymphocytes (referred to as heteruria), an important reference for early diagnosis. Now in our hospital from 1980 to 1981 confirmed 118 cases of hemorrhagic fever in patients with blood in the heterophylla observation results are reported below. Materials and Methods From the patient admission, once every other day, in the finger blood smear, Wright’s stain after counting 100 or 200 leukocytes,
