title: Cerebrospinal fluid lymphocyte subpopulations before and after pneumoencephalography.
abstract: Pneumoencephalography (PEG) did not cause significant changes in cerebrospinal fluid (CSF) lymphocyte subpopulations. Sheep erythrocyte rosette-forming cells (E-RFC) percentage was higher in CSF before (84.0) and after (81.1) PEG than in blood (63.7). The percentage of complement receptor bearing cells was significantly higher in CSF (65.3 and 64.6) than in blood (33.1). Fcgamma receptor bearing cell levels were only slightly higher in CSF (35.6%) than in blood (31.5%), and increased after PEG to 43.9%. The high percentages of both E-RFC and complement receptor bearing cells in CSF, suggest that a considerable number of these cells bear both receptors, in contrast to blood.
