37例培养阳性结核性脑膜脑炎脑脊液细胞学动态分析

目的探讨脑脊液结核分枝杆菌培养阳性结核性脑膜炎脑脊液细胞学特点。方法运用玻片细胞沉淀(粟秀初教授研制)细胞学方法,对37例使用Bactec MGIT 960培养阳性结核性脑膜炎患者的脑脊液细胞学分类特点进行动态观察与分析。结果结核性脑膜脑炎患者脑脊液白细胞总数升高,但有4例患者脑脊液白细胞数小于50×106/L。多数确诊结核性脑膜炎患者脑脊液呈混合型细胞反应,有33例(89.2%)患者脑脊液中检测到中性粒细胞,25例(67.6%)患者脑脊液中检测到浆细胞。但多数患者脑脊液(60%)以淋巴细胞为主,少量(1/3)以中性粒细胞为主。且几乎所有患者脑脊液内均可以检测到浆细胞的存在。结论确诊结核性脑膜炎患者的脑脊液白细胞数明显增高,脑脊液细胞分类主要表现为淋巴细胞为主型,少部分为中性粒细胞为主型。

Cytological features of cerebrospinal fluid in the patients with culture positive tuberculous meningitis

Objective To investigate the cytological features of the cerebrospinal fluid in the culture positive tuberculous meningitis（TBM）.Methods The cytological features of 37 cases of culture positive TBM were evaluated through the dynamic observation by using the cerebrospinal fluid sediment chamber method.Results The total number of leucocytes was increased in cerebrospinal fluid of TBM patients.The granulocytes were increased obviously and the mixed cell reactions were observed in the all stage.Conclusion The cerebrospinal fluid of the patients with culture proved TBM features by the obvious increase of white cells number with a majority of lymphocytes and a minority of granulocytes.
