Immunologic aspects of ozena.

In order to be able to describe the systemic cellular immunity in patients with ozena, the following immunologic parameters were studied in 19 ozena patients: the number of T- and B-cells, the spontaneously proliferating cells, and the transformation response of lymphocytes to phytohemagglutinin and pokeweed mitogen. No differences could be found between the ozena patients and the healthy control subjects, however. Subsequently, with the methods used, we were unable to find any systemic cellular immuno-disorders in patients with ozena.
