急性病毒性脑炎和脑膜炎的脑脊液细胞学检查

Cerebrospinal fluid cytology of acute viral encephalitis and meningitis

应用玻片离心法对９８例急性病毒性脑炎和脑膜炎患者进行脑脊液细胞学检查。发病第一周脑脊液中常见激活淋巴细胞和浆细胞，亦可见多种淋巴细胞异常形态如有丝分裂、双核细胞、异常的核分叶，偶见Ｒｕｓｓｅｌ小体及桑椹体。上述改变主要存在于急性病毒性脑炎；

Using cytological examination, the cerebrospinal fluid(CSF) of 98 patients with acute viral encephalitis was investigated. We found 81.4% activated lymphocytes and 5.8% plasma cells in CSF in the first week. In addition, various lymphoid features were disclosed in association: mitosis, binucleation, abnormal nuclear lobulation, Russell bodies, and morula in plasma cells. These cellular changes specifically existed in CSF of acute viral encephalitis, which were helpful to distinguish the said disease from tuberculous melitis and multiple sclerosis.
