The percent of E-rosette forming cells in the peripheral blood of 60 patients with Hodgkin's disease was significantly lower than in control subjects: 46.4 ± 12.3 vs. 62.4 ± 12.5. Preincubation of the mononuclear cells with levamisole, thymic humoral factor (THF) or indomethacin restored E-rosette formation to normal levels. When monocytes were removed from the mononuclear cell preparations prior to incubation, levamisole and THF retained their activity, whereas indomethacin was inactive. These results suggest a direct effect of levamisole and THF on lymphocytes in Hodgkin's disease, whereas indomethacin requires the mediation of monocytes, similarly to its reported effects on other cellular immune responses in Hodgkin's disease.
