Physical criteria of pathological processes. III. The structure of correlation between the level of the steady brain potential and the proteins of serum complement in rheumatic diseases

The activity of serum complement proteins and the level of steady brain pot ential in patients with systemic lupus erythematosus and rheumatoid arthrit is were determined. The statistical analysis indicated that there is a corr elation between the parameters of the complement system and neurophysiologi cal characteristics. The differences between rheumatoid artritis and system ic lupus erythematosus are observed in the mean values of activity of compl ement proteins and the steady potential, their dispersions, and the structu re of correlations between immunological and neurophysiological parameters.
