以免疫电子显微镜和免疫萤光技术测试Ｃ型逆转录酶病毒。测定了神经性疾患病人和正常人各４０例的病毒抗原。结果正常人全部阴性，而病人阳性率为２２．５０％，差异非常显著（Ｐ＜０．０１）；且在抗原阳性标本中见Ｃ型病毒颗粒。提示国内神经性疾病与Ｃ型逆转录病毒感染有关。另检测了５０例正常人和５４例神经性疾患病人血清病毒抗体，显示正常人全部阴性，病人阳性率为１．８５％，无显著差异（Ｐ＞０．０５）。但病人病毒抗原和抗体的阳性率相比，差异非常显著（Ｐ＜０．０１），说明测试抗原比抗体敏感。
C-type reverse transcriptase virus was tested by immuno-electron microscopy and immunofluorescence techniques. A total of 40 viral antigens were determined in patients with neurological disorders and normal controls. Results All patients were negative, but the positive rate was 22.50%. The difference was significant (P <0.01). In the antigen-positive specimens, C virus particles were found. Tip domestic neurological diseases and C-type retroviral infection. Another test of 50 cases of normal subjects and 54 cases of neurological disease in patients with serum virus antibodies, showing normal all negative, the positive rate of 1.85%, no significant difference (P> 0.05). However, the difference between the positive rate of virus antigen and antibody was very significant (P <0.01), indicating that the test antigen is more sensitive than the antibody.
