[Immunologic and biochemical changes in patients with cranio-facial pain].

The authors provide the results of an analysis of the interrelation between the immunologic and biochemical parameters in 6 groups of patients suffering from facial pains or headaches (a total of 153 patients). Significant correlations were revealed in the patients' groups with trigeminal neuralgia and periodic migrainous Horton's neuralgia. The main attention was concentrated on the following parameters: IgA in the serum, secretory IgA in the patients' saliva, % CD4 of lymphocytes and histamine concentration in the peripheral blood, concentration of beta-endorphin in the plasma, catecholamine content in the urine.
