Determination of blood serum protein reactivity in children with behavior disturbances.

The researches were carried out on two groups of children: normals and with behavior disturbances. The serum cationic state was determined by an original method, using heparin as cautions exchanger in physiological pH, and the protein reactivity; the electrophoretic mobility of serum proteins at pH 7.4; total soduim and serum proteins. The obtained results show that serum proteins in children with behavior disturbances differ from those of normals, having: 1) smaller number of serotonin-fixing sites, 2) higher strength interaction between the serotonin and proteins, 3) lower resistance to the denaturant agents which has as a consequence the increase of cationic activity in the serum, and an increased electrophoretic mobility. The data are discussed and interpreted as perturbations in the electrolytes exchange (Na+, especially) in the integration centres of the autonomic functions.
