[Cell-mediated immunity after head injuries]
In 20 patients with head trauma associated with loss of consciousness without massive damage to the tissues total count of lymphocytes T in the peripheral blood was determined, and test of lymphocyte blastic transformation and leucocyte migration inhibition were done. The investigations were done one time only, usually 5 days after trauma. In the patients the total count of lymphocytes and T-cells was decreased in the peripheral blood and production of the factor inhibiting leucocyte migration was reduced. The immune disturbances observed in these patients were due probably to the action of stress triggered by trauma.
