 AB    The influence of progesterone at the physiological concentration on
       normal donor and malignant patient peripheral blood lymphocytes
       incubated with interleukin 2 (IL-2) was investigated. Analysis of the
       phenotypes of IL-2-activated lymphocytes revealed that there was a
       difference in the positive rates of CD4+ and CD8+ cells between normal
       donors and patients with malignancies. Activated lymphocytes of normal
       adults older than 35 years of age consisted of 60-100% of CD4+ cells and
       0-30% of CD8+ cells. Donors younger than 35 years of age showed a
       positive rate of CD4+ cells, ranging from 0-100%, while CD8+ cells were
       between 0-60%. However, in patients with malignancies both CD4+ and
       CD(8+)-activated lymphocytes diffused from 0-100%. Activated lymphocytes
       of most patients were CD8+ cell dominant, which reversed the CD4+/CD8+
       ratio. Almost all patients at clinical stage IV showed a deviation of
       the positive rates of CD4+ and CD8+ cells from the normal range. It is
       an open question whether the prognosis of the patients with normal
       positive rates of CD(4+)- and CD(8+)-activated lymphocytes is favorable
       or not.
