几乎所有的炎症疾患均以引起血浆或受累组织中的体液如腹水或滑液出现可测的C—反应蛋白.血浆中的C—反应蛋白的增加常用来鉴别小儿的细菌性感染.但用脑脊液(CSF)中的C—反应蛋白来鉴别细菌性和非细菌性中枢神经系统感染尚未报告过.本文报告用胶乳凝集试验来测定CSF中的C—反应蛋白对小儿脑膜炎是一项快速而有效的辅助诊断方法.研究对象是56例年龄自生后1月～16岁的脑膜 Almost all inflammatory disorders are caused by the presence of measurable C-reactive protein in body fluids, such as ascites or synovial fluid, in the plasma or affected tissues.C-reactive protein in plasma is commonly used to identify bacterial infections in children, but cerebrospinal fluid (CSF) to identify bacterial and nonbacterial CNS infections has not been reported.This paper reports that the use of latex agglutination tests to determine C-reactive protein in CSF is a rapid and effective treatment for childhood meningitis Of the auxiliary diagnosis.Methods: 56 cases of meninges from January to 16 years after birth
