[Immunoregulation effect of traditional Chinese medicine treatment on patients with oral lichen planus].

Objective: To explore effect of traditional Chinese medicine (TCM) treatment on immune state of patients with oral lichen planus (OLP).
Methods: 30 cases of patients with OLP were treated by TCM and peripheral blood T-lymphocyte subgroup in these patients were determined.
Results: CD3, CD4 and CD4/CD3 ratio of patients with OLP were decreased significantly, compared with that of health people (P < 0.01) before TCM treatment, while after TCM treatment CD3, CD4 and CD4/CD3 ratio were increased significantly (P < 0.01) and the latter recovered to normal, 8 patients recovered, 14 cases significantly improved, and 8 cases improved.
Conclusion: TCM therapy is useful for the treatment of OLP. It acts biphasically a regulation effect on the immunologic balance of the patient.
