[State of non-specific immunoreactivity in patients with closed cranio-cerebral trauma].

Studies of the state of the non-specific humoral protection in 138 patients with craniocerebral injuries demonstrated that the bactericidal and beta-lytic activity of the serum remains relatively stable during the acute period of trauma, while the complement activity and the concentration of lysozyme are subject to significant alterations. The elevation of the lysozyme content and the enhancement of the complement activity are in direct proportion with the severity of the injury, and are revealed at the peak of the acute period of the craniocerebral trauma.
