Leukocyte migration inhibition by a brain tissue antigen and electroencephalography in uncomplicated measles.

In 11 patients with uncomplicated measles and in 10 control patients with acute enteritis, electroencephalography and leukocyte migration inhibition test using basic myelin protein as antigen were carried out. There were no EEG abnormalities and no migration inhibition in the control group. Leukocyte migration inhibition was observed in 9 measles patients; among these 5 had slight or moderate EEG abnormalities. It is suggested that EEG abnormalities have the same pathological background in uncomplicated measles as in measles encephalitis.
